Title: Forests: An Endangered Resource
Post by: Sigmetnow on October 11, 2015, 07:40:25 PM
Forests
Climate change is increasing the vulnerability of many U.S. forests through fire, insect infestations, drought, and disease outbreaks. Forests play an important role in absorbing and storing carbon dioxide, but the rate of uptake is projected to decline.

Explore interactions between climate change and forests.

The Rapid and Startling Decline Of World’s Vast Boreal Forests

Scientists are becoming increasingly concerned about the fate of the huge boreal forest that spans from Scandinavia to northern Canada. Unprecedented warming in the region is jeopardizing the future of a critical ecosystem that makes up nearly a third of the earth’s forest cover.

In a surprising new study, scientists say they’ve pinned down the climate factor most strongly tied to variations in terrestrial carbon storage — that is, the ability of plants and other features of the Earth’s surface to take up carbon, thus preventing it from going into the atmosphere. They’re arguing that the biggest driver is tropical nighttime temperatures, which are expected to warm at a faster rate than average temperatures otherwise will.
...
“The idea here is that on warm nights, plants — and other parts of the ecosystem as well, potentially — are consuming and using up more of their sugars and losing that carbon to the atmosphere more than they do on cooler nights,” Anderegg said.

California Drought Puts Tens of Millions of Big Trees at Risk: Study
Quote
As many as 58 million of California's large trees are at risk due to the ongoing drought, according to a new study — and researchers say that means big changes may be ahead for the state's forests even if El Nino does drive increased rainfall in the coming year.

Using imaging tools on board the Carnegie Airborne Observatory, ecologist Greg Asner and a team from the Carnegie Institution for Science surveyed forests affected by the drought that's been ongoing since 2012. Their research, which shows how California's forest canopies have lost water over time, was published Monday in the Proceedings of the National Academy of Sciences.

Nine-year-old boy plants seed that yields 3 trillion trees
Quote
Felix challenged his classmates—and ultimately, children throughout the world—to plant a million trees in each country, an idea that grew into an international youth organization called “Plant-for-the-Planet.” In 2011, the UNEP turned its Billion Tree Campaign over to the organization Felix had started. By that time, the UN program had celebrated the planting of 12 billion trees.
Quote
The team also found that on average, some 15 billion trees are lost each year while only 5 billion new trees are gained, a net loss of 10 billion trees per year. So if we want to maintain the current total of 3 trillion, we need to achieve some combination of planting a lot more trees and reducing the number that are lost.

Forest Loss Pushes Far Beyond Plantation Boundaries in South America, Africa
Quote
Which of the world’s forests are natural, and which have been planted by humans?

It seems like a simple question, but researchers have been struggling to answer it for years. Satellites can’t easily distinguish between primary and secondary forests, which occur naturally, and planted forests, which are created and managed by people to supply timber, rubber and other commodities. And few countries provide accurate maps of plantation locations.

But we’re getting closer. Researchers from Global Forest Watch and Transparent World recently mapped tree plantations in seven heavily forested nations, and found that in most of the countries, more than 90 percent of tree cover loss is occurring within natural forests. That’s a problem since natural forests, especially those in the tropics, provide much greater climate, water and biodiversity benefits over planted landscapes.

Chinese Oil Companies to Buy One-Third of Ecuador's Rainforests
Quote
In a move that has angered local tribes and environmental activists, Ecuador plans to sell more than a third of its rainforests to Chinese oil companies.

The country's Amazonian rainforest measures 8.1 million hectares (20 million acres) in size – slightly larger than the total area of South Carolina – according to a 2008 study published in PLOS ONE. The reason for this sale is twofold: Ecuador owes China billions of dollars in debt, and the country's rainforests are rich in oil reserves, the report added.

As of last summer, Ecuador was at least $7 billion in debt to China, Reuters said. That's more than 10 percent of the country's GDP, and it gave Chinese oil companies the ability to bargain their way into those useful rainforests.

Risk level rises for North American forests
Quote
“Our analysis shows virtually all US forests are now experiencing change and are vulnerable to future declines. Given the uncertainty in our understanding of how forest species and stands adapt to rapid change, it’s going to be difficult to anticipate the type of forests that will be here in 20 to 40 years.”
Quote
“When you chop down trees, you create hotspots in the landscape that are just scorched by the sun. These hotspots can change the way that heat moves through a landscape,” says the report’s lead author, Kika Tuff, a PhD student at the university’s department of ecology and evolutionary biology.

Low air pressure in the cleared spots pulls the cool moist air from the shade of the trees, to be replaced by hot, dry air. The cleared areas then get the rainfall, while the nearby forest dries.

The warming effect is most pronounced within between 20 and 100 metres of the forest’s edge, where temperatures can be as much as 8°C higher than deep in the forest interior.

Since 20% of the world’s remaining forests lie within 100 metres of an edge, and more than 70% lie within a kilometre of an edge, the discovery suggests that the warming effect could be happening anywhere, or everywhere.

Forest restoration: from Stone Age to drone age
Forest restoration still relies on back-breaking manual labor with basic tools like spades, machetes, and hoes. But now researchers are developing techniques for automated forest restoration — or AFR — using drones to survey forests, gather and disperse seeds, and control weeds, among other possibilities.

China's forest conservation programs show a decade of improvement in tree cover. 
Quote
But that didn't mean China's thriving manufacturing industry was just going without timber. The nation now sees significant timber imports from places like Vietnam, Madagascar, and Russia, Dr. Viña says. "We think that success in reducing deforestation in China is basically being transferred into deforestation in other regions," he says.
Globally, deforestation continues, but at a slowing pace.
Quote
Although global deforestation has yet to reverse course, reports do suggest it is slowing. In fact, global deforestation rates have been cut in half since 1990, according to the United Nations Food and Agriculture Organization’s Global Forest Resources Assessment (FRA). In the 1990s, an average of 0.18 percent of the world's forests were lost each year, but from 2010 to 2015, that average loss dropped to 0.08 percent.

"It is encouraging to see that net deforestation is decreasing and that some countries in all regions are showing impressive progress. Among others, they include Brazil, Chile, China, Cape Verde, Costa Rica, Philippines, Republic of Korea, Turkey, Uruguay, and Viet Nam," FAO Director-General Jose Graziano da Silva said in a press release in 2015.

And with decreasing deforestation, that means more carbon storage. The FAO also reported that carbon emissions from forests decreased by 25 percent from 2001 to 2015.

Ash dieback and beetle attack likely to 'wipe out' ash trees in UK and Europe
Quote
Almost all the ash trees in the UK and across Europe are likely to be wiped out by a “double whammy” of a bright green borer beetle and the fungus that causes ash dieback, according to a comprehensive new academic analysis.

The loss of the ash, one of the most abundant tree species in the UK, would mean losing even more trees than the 15 million elms killed by Dutch elm disease in the 1970s. Ash is the most common hedgerow tree, with 60,000 miles of tree lines. It is the second most common tree in woodland, after the oak, and there are many ash trees in towns and cities.

Amazing. Market value of 180K cu. m of wood even discounted and amortized over a decade is worth all that old forest.

There is a quote from Aldo Leopold to the effect that a trade presented as getting something for giving nothing turns into getting nothing for losing everything. You can't bargain with Nature in terms of human values, She sets the terms, and exacts a hard bargain.

Invasive insects are ravaging U.S. forests, and it’s costing us billions
Quote
Last week, a group of researchers published saddening news about “sudden oak death,” spread by an invasive water mold, that has killed over a million trees in coastal California. The pathogen, they found, simply cannot be stopped — though it can still be contained, and the harm mitigated. But it is too extensively established now in California to eradicate.

Unfortunately, it’s a familiar story. The U.S. is subject to the introduction of 2.5 new invasive insects into its forests ever year, according to a comprehensive new analysis of this problem, in the journal Ecological Applications, by Gary Lovett of the Cary Institute of Ecosystem Studies and a group of 15 colleagues from Harvard, the U.S. Department of Agriculture, and numerous other institutions. And that number is just for insects — it doesn’t count diseases, like sudden oak death.

Young Forests Can Store ‘Enormous’ Amounts of Carbon
Quote
Woodland areas that regrow after forest fires, logging operations or other disturbances can sequester huge amounts of carbon dioxide and they play an unexpectedly valuable role in mitigating climate change, according to a study by 60 scientists from across the globe.

The research, published Friday in the journal Science Advances, is the first to quantify how much carbon these so-called second-growth forests can sequester, and it turns out it’s huge. The scientists found that over the span of 40 years, Latin American second-growth forests can stash away the equivalent of 21 years worth of the region’s human carbon dioxide emissions.

Cattle Grazing Is Now Causing Massive Deforestation Hotspots In The Peruvian Amazon
Quote
Deforestation in the Amazon has been a growing problem over the past five decades, with ranchers leading the way in clearing rainforest for cattle and cultivation. But while Brazil, the largest country in South America, seems on track to reduce deforestation, other major Amazonian countries like Peru are increasingly struggling to protect their share of the world’s largest rainforest.

In fact, a new wave of deforestation is underway in the Huanuco region of central Peru, which now has the highest concentration of the deforestation in the country, according to an Amazon Conservation Association (ACA) report published this month. The report is based on algorithms of satellite data from 2013 through 2015 and points to cattle grazing as the main culprit, Matt Finer, senior research specialist at the ACA told ThinkProgress. “We just hadn’t really dealt with that driver before. You hear that more in the context of Brazil.”

102 million dead California trees 'unprecedented in our modern history,' officials say
Quote
The number of dead trees in California’s drought-stricken forests has risen dramatically to more than 102 million in what officials described as an unparalleled ecological disaster that heightens the danger of massive wildfires and damaging erosion.

Officials said they were alarmed by the increase in dead trees, which they estimated to have risen by 36 million since the government’s last survey in May. The U.S. Forest Service, which performs such surveys of forest land, said Friday that 62 million trees have died this year alone.

“The scale of die-off in California is unprecedented in our modern history,” said Randy Moore, the forester for the region of the U.S. Forest Service that includes California. Trees are dying “at a rate much quicker than we thought.”

Scientists say five years of drought are to blame for much of the destruction. The lack of rain has put California’s trees under considerable stress, making them more susceptible to the organisms, such as beetles, that can kill them.  Unusually high temperatures have added to the trees’ demand for water, exacerbating an already grim situation.

California Forests Failing to Regrow After Intense Wildfires
Huge, destructive fires are more common with climate change, and the loss of regeneration threatens to exacerbate global warming.
Quote
There are warning signs that some forests in the western U.S. may have a hard time recovering from the large and intense wildfires that have become more common as the climate warms.

After studying 14 burned areas across 10 national forests in California, scientists from UC Davis and the U.S. Forest Service said recent fires have killed so many mature, seed-producing trees across such large areas that the forests can't re-seed themselves. And because of increasingly warm temperatures, burned areas are quickly overgrown by shrubs, which can prevent trees from taking root.

"With high-severity fires, the seed source drops off," said study co-author Kevin Lynch, a forest researcher at UC Davis. "We aren't seeing the conditions that are likely to promote natural regeneration."

Historically, severe fires were uncommon in the forests covered by the study, largely made up of yellow pines and mixed conifers, but extended drought and heatwaves have exacerbated fire conditions across the West. The changing climate is also seen as a factor in recent wildfires in the Southeast, which is also mired in drought.

For the study, published Wednesday in the journal Ecosphere, the researchers surveyed 1,500 plots in burned areas at different elevations in the Sierra Nevadas, Klamath Mountains, and North Coast regions. There was no natural conifer regeneration at all in 43 percent of the plots, they reported.

Brazil halves environment budget amid rising Amazon deforestation
Quote
In a bid to contain a growing budget deficit, the government has slashed the funding to enforce forest protection laws

The Brazilian government is cutting its environment ministry budget by 51% as part of a bid to limit the country’s spiralling deficit.

The cuts come as deforestation rates are rising, driven by demand for timber, soy and beef. The Amazon region saw a 29% increase in forest clearance last year, according to preliminary data from Brazil’s National Space Research Institute.

It is an even steeper drop in spending than the 31% Donald Trump’s administration is proposing for the US Environmental Protection Agency.

The environment ministry oversees Ibama, the agency responsible for enforcing laws to protect the forest. Sharp spending cuts risk weakening its capacity to carry out inspections, warned NGO Observatorio do Clima.

And as far north as three forks, montana where the jefferson, madison and galltin come together to make the missouri.  Nothing is replacing as a succession species that i saw. That whole area is monoculture pine, too much for the beetle to eat, and winters not cold enuf to kill them. One of the people i talked to is trying to plant spruce, but it's hard. Pheromone packets help a little. Saw it as far east as nebraska, but more varied trees there.

TOP CLIMATE SCIENTIST JOINS COALITION IN CALLING FOR AN END TO CLEARCUTS AND TIMBER PLANTATIONS
July 10, 2018
Quote
One of the world’s leading climate scientists joined a coalition of 18 conservation, scientific, and community organizations calling on Oregon’s new Carbon Policy Office (CPO) and the Department of Forestry (ODF) to do an about-face on the state’s evolving forest carbon policy and to immediately implement measures to curb the harmful climate impacts of clearcutting and tree plantations. In a thirteen-page letter sent to CPO Director Kristen Sheeran and State Forester Peter Daugherty, the coalition urges the state to abandon the timber industry’s preferred ‘hands off’ approach to forests and climate change in favor of a forest carbon policy based on science and principles of environmental justice. The letter was also sent to forest policy makers in Washington state since that state is on a similar track with respect to forests and climate. ...

I was up in Shoshone and Yellowstone back in 2016 and was shocked at how bad it was. I have photographs from the 80s and early 90s when I used to go up there as a kid and it had totally changed. The snow patches and ice had visibly retreated way up and in some spots beetle kill went all the way up to the tree line.

I thought I had seen the worst, but that came when we trekked up to the Yoho National Forest in Canada. Huge swaths of that forest were dead or dying when we went through. It hadn't yet gotten to Banff, but it was knocking on the door. I feel fortunate I got to see Banff before it hit. What a beautiful place.

Wildfires In The U.S. Are Getting Bigger
https://fivethirtyeight.com/features/wildfires-in-the-u-s-are-getting-bigger/
"That dichotomy — fewer fires, more land ablaze — is in keeping with long-standing trends. Since 1985, the trend in the number of wildfires hasn’t changed much, but the trend for total acreage burned has gone up and up and up. So what gives? Experts say there’s no single cause in the midst of all that smoke. Instead, the trend is probably related to the interaction of changing climate, short-term weather patterns and a philosophical shift in how we manage both forests and fires."
...
"Fire managers began to change their philosophy and allow some fires to burn in a more natural way in the 1970s.... Over the last 15 or 20 years, that’s become more of the norm. In the past, every little fire that started got put out before it burned much land. Today, one fire might be allowed to eat up much more built-up kindling... It’s better to let the fire burn more acreage than risk lives unnecessarily.

But transitioning to a more natural sort of fire management isn’t necessarily going to return the forests to a past state of balance with the blaze, Collins warned. Decades of extreme fire prevention have altered forest adaptation. Areas that burn severely today might never grow back the same way. “You can’t just turn the switch back on,” he said. “We might be turning [some forests] into shrublands.”

Iconic Forests Reaching Climate Tipping Points in American West, Study Finds
Quote
Climate change in the American West may be crossing an ominous threshold, making parts of the region inhospitable for some native pine and fir forests to regrow after wildfires, new research suggests.

As temperatures rise, the hotter, drier air and drier soil conditions are increasingly unsuitable for young Douglas firs and ponderosa pines to take root and thrive in some of the region's low-elevation forests, scientists write in a study published Monday in the Proceedings of the National Academy of Sciences. Wildfires in these areas could lead to abrupt ecosystem changes, from forest to non-forest, that would otherwise take decades to centuries, the study says.

"Once a certain threshold was crossed, then the probability of tree establishment decreased rapidly," said Kimberley Davis, a researcher at the University of Montana and lead author of the study. "The climate conditions are just a lot less suitable for regeneration." ...

Hurricane Maria Devastated Puerto Rico’s Forests at an Unprecedented Rate
The tropical storm snapped and uprooted trees long thought to be the hardiest—and some of the most important for keeping carbon out of the atmosphere.
Quote
As Hurricane Maria raged across the island with rampaging rains and winds gusting at up to 155 miles per hour, it inflicted serious damage on 20 to 40 million trees. Some species were hit harder than others, and in the aftermath of the onslaught, the makeup of Puerto Rico’s lush ecosystems has likely been permanently altered. And Maria’s destructive powers might well be a harbinger of far worse times to come: With global temperatures on the rise, the researchers forecast that similar storms will follow.

“These hurricanes are going to kill more trees...the factors that protected many trees in the past will no longer apply,” study author María Uriarte, an environmental biologist at Columbia University’s Earth Institute, said in a statement.
...
But not all species were affected in the same way. “There were winners and losers,” Uriarte told Mark Tutton at CNN. Uriarte was surprised to find that large, old hardwoods like tabonucos (candlewoods) and ausubos (bulletwoods)—thick, dense, slow-growing breeds that have traditionally showed resilience in the face of natural disasters—were among the fallen. The loss of these staple species further endangers the birds and other wildlife that typically make their homes in their branches, trunks, and leaves. Others, like the common sierra palm, which have the flexibility to sway and buckle in the gales and easily resprout after damage, fared far better.

Ultimately, these long-term shifts in composition could make for “lower saturated and less diverse forests,” Uriarte said in a statement. And that could have some serious long-term consequences.

With their lower density, palms can’t store as much carbon as hardwoods. If these forests morph into glens of short, skinny, light-bodied trees, they might not do as good a job keeping carbon out of the atmosphere. Additionally, every bout of forest destruction takes trees out of commission, compromising the ability of Earth’s ecosystems to stave off climatic changes, Yadvinder Malhi, an ecosystem scientist at the University of Oxford who was not involved in the study, told Tutton at CNN.

Emissions from the decay of felled trees could even begin to outweigh the carbon taken in by replacements, turning these forests into net carbon emitters. In other words, the landscapes of the future might end up feeding the very changes that put them at risk. ...

The secret deal to destroy paradise: The story behind the single biggest threat to the rainforests of Indonesia.
https://news.mongabay.com/2018/11/the-secret-deal-to-destroy-paradise/ (https://news.mongabay.com/2018/11/the-secret-deal-to-destroy-paradise/)

This is only a small extract, please go to the link:

Quote
The threat to the rainforests of Indonesia was very real. Since the turn of the century, only Brazil has lost more rainforest than Indonesia. One of the leading causes of this deforestation was a boom in industrial-scale plantations that began in the early 2000s. Those plantations enabled Indonesia to become the leading producer of palm oil, an edible oil used in an endless array of consumer products. But it also sparked an environmental crisis, as the carbon locked up in rainforests was released into the atmosphere.

The volume of greenhouse gas emissions from Indonesian rainforests has made it a matter of international concern. Norway has pledged $1 billion in an attempt to incentivize reforms to curb them. Since 2015, the administration of President Joko Widodo has sought to rein in the plantation industry, most recently by enacting a temporary ban on any new permits for palm plantations. Though just a small proportion of the Tanah Merah project has been developed, the permits were issued before the ban came into force, and the forest remains slated for destruction.

Today, an area larger than Manhattan has been cleared within the Tanah Merah project. This is only a fraction of the total project area. If the rest is bulldozed as planned, it will release as much emissions as Virginia produces by burning fossil fuels each year. If the giant sawmill that is today being constructed on the land is completed, it will suck in timber for years to come, settling the fate of swathes of rainforest in southern Papua.

Logging Is the Leading Driver of Carbon Emissions From US Forests

...

Many people are aware of the importance of protecting rainforests in Brazil to help mitigate climate change, but few realize that more logging occurs in the US, and more wood is consumed here, than in any other nation globally. The rate and scale of logging in the Southeastern US alone is four times that in South American rainforests.

...

Carbon emissions from logging in the US are ten times higher than the combined emissions from wildland fire and tree mortality from native bark beetles. Fire only consumes a minor percentage of forest carbon, while improving availability of key nutrients and stimulating rapid forest regeneration. Within a decade after fire, more carbon has been pulled out of the atmosphere than was emitted. When trees die from drought and native bark beetles, no carbon is consumed or emitted initially, and carbon emissions from decay are extremely small, and slow, while decaying wood helps keeps soils productive, which enhances carbon sequestration capacity over time.

On the other hand, industrial logging — even when conducted under the euphemism of “thinning” — results in a large net loss of forest carbon storage, and a substantial overall increase in carbon emissions that can take decades, if not a century, to recapture with regrowth. Logging also tends to make fires burn faster and more intensely while degrading a forest ecosystem’s ability to provide natural protections against extreme weather events.

Consider this: About 28 percent of tree carbon is contained in branches, and this is emitted when they are burned after logging operations. An additional 53 percent of the carbon in trees removed from forests is emitted as waste in the manufacturing and milling process. Overall, about two-thirds of the carbon in trees that are logged for lumber quickly become greenhouse gas emissions.

When trees are cut down and burned to generate “biomass” electricity under the guise of “renewable energy,” 100 percent of the carbon is emitted. Incinerating wood for energy emits evenmore CO2 than burning coal, for equal energy produced. Yet, the expansion of US production of wood pellets to fuel power stations in Europe has been spreading like wildfire across the Southeast, accelerating the destruction of some of our nation’s most ecologically-important forests and putting the health of some of the nation’s most vulnerable communities at increased risk.

Wood wide web: Trees' social networks are mapped

Research has shown that beneath every forest and wood there is a complex underground web of roots, fungi and bacteria helping to connect trees and plants to one another.

This subterranean social network, nearly 500 million years old, has become known as the "wood wide web".

Now, an international study has produced the first global map of the "mycorrhizal fungi networks" dominating this secretive world.

Details appear in Nature journal.

...
Using millions of direct observations of trees and their symbiotic associations on the ground, the researchers could build models from the bottom up to visualise these fungal networks for the first time.

...

The research reveals how important mycorrhizal networks are to limiting climate change - and how vulnerable they are to the effects of it.

...

Mycorrhizal fungi are those that form a symbiotic relationship with plants.

There are two main groups of mycorrhizal fungi: arbuscular fungi (AM) that penetrate the hosts's roots, and ectomycorrhizal fungi (EM) which surround the tree's roots without penetrating them.

EM fungi, mostly present in temperate and boreal systems, help lock up more carbon from the atmosphere. They are more vulnerable to climate change.

AM fungi, more dominant in the tropics, promote fast carbon cycling.

According to the research, 60% of trees are connected to EM fungi, but, as temperatures rise, these fungi - and their associated tree species - will decline and be replaced by AM fungi.

"The types of fungi that support huge carbon stores in the soil are being lost and are being replaced by the ones that spew out carbon in to the atmosphere."

A New Study Finds That Cutting Down One Forest Can Make Neighboring Forests Hotter



Areas cleared of forests bleed heat to neighboring forests, and this fuels increases in temperatures there, new research has found. Average temperatures in forests around the world are already rising because of climate change; this leaked heat exacerbates the problem and accelerates local extinctions of forest-dwelling species.



What struck Sinervo was the unusually high rate of extinction in Madagascar, one of the most biodiverse countries in the world. "I was intrigued why Madagascar had a much higher observed extinction rate  (of lizards) than any other [country] and I saw that Madagascar had warmed faster than mainland Africa," Sinervo says.
In Madagascar, two forest reserves analyzed in the 2010 paper reported an increase in maximum temperatures of two degrees Celsius (3.6 degrees Fahrenheit) and also a 75 percent rate of deforestation in adjacent areas. However, there was insufficient data at the time to investigate whether the rising forest temperatures were related to the nearby deforestation.



In tropical forests, the study found, loss of half of the forest cover leads to an increase of about 1.08 degrees Celsius (1.94 degrees Fahrenheit) in the land surface temperature of the adjacent forest. Based on the model, the team predicted that, in Brazil, current rates of deforestation could lead to as much as 1.45 degrees Celsius (2.61 degrees Fahrenheit) of additional warming by 2050

Disrupting Tropical Soil Could Be Releasing Previously Unaccounted Ancient Carbon Dioxide


Researchers investigated 19 sites in the Democratic Republic of Congo for dissolved organic carbon that had been drained into streams and rivers. As thousand-year-old soil is upturned and disrupted, they found that older dissolved organics from areas that had seen higher rates of deforestation were richer in energy and more chemically diverse.

“We estimate that while deforestation reduces the overall flux of dissolved organic carbon by approximately 56%, it does not significantly change the yield of biolabile dissolved organic carbon,” wrote the authors. “Ultimately, the exposure of deeper soil horizons through deforestation and agricultural expansion releases old, previously stable, and biolabile soil organic carbon into the modern carbon cycle via the aquatic pathway.”

Areas that have been heavily deforested were more likely to have leached organic carbon older and more biodegradable than organic carbon put off. Older, more unstable organic carbon released when the soil is upturned or disrupted. Microscopic organisms that consume released CO2 then pump it back into the atmosphere, potentially worsening impacts of the greenhouse effect.

"In many ways, this is similar to what happened in the Mississippi River Basin 100 years ago, and in the Amazon more recently," said study author Rob Spencer in a statement. "The Congo is now facing conversion of pristine lands for agriculture. We want to know what that could mean for the carbon cycle."

'Football pitch' of Amazon forest lost every minute
Quote
An area of Amazon rainforest roughly the size of a football pitch is now being cleared every single minute, according to satellite data. The rate of losses has accelerated as Brazil's new right-wing president favours development over conservation.

Satellite images show a sharp increase in clearances of trees over the first half of this year, since Jair Bolsonaro became president of Brazil, the country that owns most of the Amazon region. The most recent analysis suggests a staggering scale of losses over the past two months in particular, with about a hectare being cleared every minute on average.

The single biggest reason to fell trees, according to official figures, is to create new pastures for cattle, and during our visit we saw countless herds grazing on land that used to be rainforest.

What does Brazil's new policy mean?
According to a senior Brazilian environment official, the impact is so "huge" that he took the risk of giving us an unauthorised interview to bring it to the attention of the world.

We had to meet in secret and disguise his face and voice because Mr Bolsonaro has banned his environment staff from talking to the media. Over the course of three hours, a startling inside picture emerged of small, under-resourced teams of government experts passionate about saving the forest but seriously undermined by their own political masters.

Multi-year drought caused massive forest die-off in Sierra Nevada
https://phys.org/news/2019-07-multi-year-drought-massive-forest-die-off.html

The researchers warn that matters are expected to get worse as global mean temperatures increase.

“Parts of the Sierra Nevada reached a ‘tipping point’ in 2015, where annual precipitation plus stored subsurface water were not enough to meet the water demand of the forest,” Bales said.
The trees in California’s mixed-conifer mountain forests have roots that can draw water from as deep as 5 to 15 meters down, which has historically protected the trees against even the worst multiyear droughts.
But the severity of California’s 2012-2015 dry-spell “exceeded this safety margin,” the researchers said. When forest stands exhausted the subsurface moisture, they became vulnerable to attack by pests, leading to widespread tree death.

"It's a catastrophe. German forests are close to collapsing," Dohle added in an interview with t-online, a online news portal of Germany's Ströer media group.

Low rainfall last summer saw Germany's rivers reach extreme lows, with some waterways still struggling and forests prone to fire.

"These are no longer single unusual weather events. That is climate change," said Dohle.

Amazon Deforestation Accelerating Towards Unrecoverable 'Tipping Point'
https://www.theguardian.com/world/2019/jul/25/amazonian-rainforest-near-unrecoverable-tipping-point

Deforestation of the Brazilian Amazon has surged above three football fields a minute, according to the latest government data, pushing the world’s biggest rainforest closer to a tipping point beyond which it cannot recover.

The sharp rise – following year-on-year increases in May and June – confirms fears that president Jair Bolsonaro has given a green light to illegal land invasion, logging and burning.

The steady erosion of tree cover weakens the role of the rainforest in stabilising the global climate. Scientists warn that the forest is in growing danger of degrading into a savannah, after which its capacity to absorb carbon will be severely diminished, with consequences for the rest of the planet.

...There are a number of tipping points which are not far away,” said Philip Fearnside, a professor at Brazil’s National Institute of Amazonian Research. “We can’t see exactly where they are, but we know they are very close. It means we have to do things right away. Unfortunately that is not what is happening. There are people denying we even have a problem.”

Right now, upwards of 300 million trees are being planted in B.C. annually, a significant portion of it designated for areas that have previously burned. But Aitken says the fertility of landscape is inconsistent, as dry heat in some areas has stripped the soil of its ability to support trees.

"Some areas will likely convert from being forests to being more like grasslands at those very dry margins at the extent of the forest," she said.

Future of Amazon Deforestation Data in Doubt as Research Head Sacked
https://news.mongabay.com/2019/08/future-of-amazon-deforestation-data-in-doubt-as-research-head-sacked/

The Brazilian government and the world have relied on the INPE (Brazilian National Institute of Space Research) satellite monitoring system to track deforestation since 1988, without controversy. INPE’s data gathering program has been hailed as one of the best such operations in the tropics.

However, after INPE reported a major uptick in the rate of Brazilian Amazon deforestation in June and July 2019, as compared with the same months in 2018, the Bolsonaro administration responded angrily by accusing the agency of manipulating data, of lying, and of being in conspiracy with international NGOs.

On August 2, the president fired Ricardo Magnus Osório Galvão, the head of INPE, leaving officials inside the institution concerned for the future of the satellite monitoring program. The government has repeatedly said it plans to develop a costly, privatized deforestation tracking system which would replace INPE.

Galvão’s removal triggered an outcry from scientists, NGOs and Brazilian federal prosecutors who are concerned over the threat to the future accuracy of Amazon deforestation monitoring. The Bolsonaro administration plans to announce a replacement shortly.

Mass destruction of the Amazon now underway, and this is just the beginning.

https://www.theguardian.com/world/2019/aug/07/bolsonaro-amazon-deforestation-exploded-july-data

Bolsonaro rejects 'Captain Chainsaw' label as data shows deforestation 'exploded'
Data says 2,254 sq km cleared in July as president says Macron and Merkel ‘haven’t realized Brazil’s under new management’

Quote
According to a report in the Estado de São Paulo newspaper, Amazon destruction “exploded” in July with an estimated 2,254 sq km (870 sq miles) of forest cleared, according to preliminary data gathered by Brazil’s National Institute for Space Research, the government agency that monitors deforestation.

That is an area about half the size of Philadelphia and reportedly represents a 278% rise on the 596.6 sq km destroyed in July last year.

“It’s almost as if a licence to deforest illegally and with impunity has been given, now that you have the [environmental] inspection and control teams being attacked by no less than the president of the republic and the environment minister,”

In recent weeks the globally respected National Institute for Space Research has found itself at the eye of a political storm as a result of the inconvenient truths revealed by its data.

Earlier this month, with alarm growing about the consequences of the intensifying assault on the Amazon, its director, Ricardo Galvão, was sacked after contesting Bolsonaro’s “pusillanimous” claims he was peddling lies about the state of the Amazon.

Galvão’s successor, the air force colonel Darcton Policarpo Damião, looks set to follow a more Bolsonarian line. In an interview this week Damião said he was not convinced global heating was a manmade phenomenon and called such matters “not my cup of tea”.

Pope Francis – who is preparing to host a special synod on the Amazon in October – has also incurred Bolsonaro’s wrath on the environment.

In June the Argentinian leader of the Catholic church questioned “the blind and destructive mentality” of those seeking to profit from the world’s biggest rainforest. “What is happening in Amazonia will have repercussions at a global level,” he warned.

Asked about those comments, Bolsonaro offered a characteristically unvarnished response, suggesting they reflected an international conspiracy to commandeer the Amazon.

“Brazil is the virgin that every foreign pervert wants to get their hands on,” Bolsonaro said.

"Between 1990 and 2015, the area covered by forests and woodlands increased by 90,000 square kilometres - an area roughly the size of Portugal in the EU". The EU has strong policies to increase the size of its forests and it's working.

New Study Shows Impact of Large Scale Tree Death on Carbon Storage
https://phys.org/news/2019-08-impact-largescale-tree-death-carbon.html

Largescale 'disturbances', including fires, harvesting, windstorms and insect outbreaks, which kill large patches of forest, are responsible for more than a tenth of tree death worldwide, according to new research at the University of Birmingham

Researchers in the Institute for Forest Research (BIFoR) at the University of Birmingham studied satellite-based observations of forest lost between 2000 and 2014, and assessed the typical time interval between large disturbance events across the world's forests.

The team then used a computational model to calculate the impact of these events on tree deaths—measured as the amount of carbon stored in the wood of dead trees—and found that they accounted for 12 per cent of tree death overall. Their simulations showed how even small changes to the frequency of large-scale disturbances can have a significant effect on forest carbon stocks in 44 per cent of the world's dense forests.

Tree-damaging pests pose ‘devastating’ threat to 40% of US forests

https://www.theguardian.com/environment/2019/aug/12/us-forests-pests-risk-climate-crisis-resource (https://www.theguardian.com/environment/2019/aug/12/us-forests-pests-risk-climate-crisis-resource)

Some excerpts:

Tree-damaging pests have already destroyed swathes of US woodland, with the American chestnut virtually wiped out by a fungal disease and elms blighted by Dutch elm disease. About 450 overseas pests that damage or feed on trees have been introduced to US forests due to the growth in international trade and travel.

A PNAS-published study of the 15 most damaging non-native forest pests has found that they destroy so many trees that about 6m tons of carbon are expelled each year from the dying plants. This is the equivalent, researchers say, of adding an extra 4.6m cars to the roads every year in terms of the release of planet-warming gases.

Together, these maladies pose a growing threat to US forests that are coming under increasing strain from rising temperatures and altered rainfall and wildfire patterns, particularly in the west of the country, due to global heating.

There are an estimated 6bn dead trees standing in the US west, with more trees now dying due to disease, insects and wildfire than are being felled for wood products.

Satellite data show the Río Plátano Biosphere Reserve lost more than 10 percent of its tree cover between 2001 and 2017, more than a third of which happened within the last three years of that time period. Preliminary data for 2019 indicate Río Plátano is experiencing another heavy round of forest loss this year, with UMD recording around 160,000 deforestation alerts in the reserve between January and August, which appears to be an uptick from the same period in 2018.

If you understand the science of this - this is VERY BAD!

Research: Link Between Increased Atmospheric Vapor Deficit and Worldwide Loss of Vegetation
https://phys.org/news/2019-08-link-atmospheric-vapor-deficit-worldwide.html

Scientists have been studying the possible repercussions of global warming for several years, and suggest it is likely to lead not only to warmer temperatures, but also changes to weather patterns. One such weather change not often mentioned is VPD, which is the difference in air pressure due to water vapor during fully saturated times versus times when it unsaturated. When VPD is increasing, there is less water in the air. VPD is important because of its impact on plants. When VPD rises a certain amount, plants react by closing their stomata, the pores in their leaves, to prevent water loss. But this also shuts down the release of oxygen and the absorption of carbon dioxide—partially shutting down photosynthesis and slowing growth. In this new effort, the researchers wondered if there might be a connection between observed losses of vegetation worldwide and changes to VPD in some parts of the world.

To find out, the researchers obtained datasets that included observation information from across the globe going all the way back to the 1950s. When focusing on VPD, they found that prior to the 1990s, VPD increased only slightly. But after 1998, the VPD grew quite dramatically—by up to 17 times over the next several years in some places, and it remained at those levels. They also found that over half of all vegetated land on the planet experienced a rise in VPD. The researchers also found that the upswing in VPD occurred in lockstep with the rise in global temperatures and the decrease in worldwide vegetative cover. They suggest that global warming is pushing VPD ever higher, resulting in more loss of vegetation—and because the planet is growing hotter, they predict that VPD will continue to increase, as well, resulting in diminishing vegetative cover.

I just returned from a trip out west, Yellowstone seems to be recovering a little from the beetle attack. I was there two years ago and was shocked by the extent of damage. This time the trees seem to be coming back. I also see a few deciduous trees appearing at higher elevations than before.

Fires are raging at a record rate in Brazil’s Amazon rainforest, and scientists warn that it could strike a devastating blow to the fight against climate change.

The fires are burning at the highest rate since the country’s space research center, the National Institute for Space Research (known by the abbreviation INPE), began tracking them in 2013, the center said Tuesday.

There have been 72,843 fires in Brazil this year, with more than half in the Amazon region, INPE said. That’s more than an 80% increase compared with the same period last year.
