American Trees Are Moving West, and No One Knows Why

https://www.theatlantic.com/science/archive/2017/05/go-west-my-sap/526899/

“Different species are responding to climate change differently. Most of the broad-leaf species—deciduous trees—are following moisture moving westward. The evergreen trees—the needle species—are primarily moving northward,”

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/

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.
