I believe that Co2 emissions will be cut drastically by 2050 (50-80% from today's levels) and eliminated by 2100.

I believe in unicorns and sparkle ponies.

In my opinion, there is actually no evidence of this being likely to occur.

SH, El Cid talked about emissions, and I believe he is correct in that statement.
 Your graph of CO2 ppm in the atm. shows the state variable, whereas emissions are the flow.

Yes. I understand. I simply have less confidence in the accuracy of global emissions data as I do not know how it is calculated. I have far more confidence in a single measure, using a fixed technique.

Do you have a go to site for the global emissions metric?

Still Co2 levels show stock, emissions show flow. The change in Co2 levels shows something closer to the annual emission numbers (although likely with a lag). Besides, I was talking about the future path of emissions.

Where do you draw your emissions data?

New York City's newest park, Little Island, opens to public
Quote
The public park on New York City's Hudson River finally opened on May 21 nearly seven years after plans were unveiled, thanks to billionaire media mogul Barry Diller, whose $260 million donation has further transformed the once-derelict West Side of Manhattan.

The island was built on the pillars of the former Pier 54, connected to Manhattan by a walkway that will take visitors from the trendy Meatpacking District to the site where survivors of the Titanic were taken and from where the Lusitania departed.

The West Side, once dominated by a bustling port, deteriorated into industrial eyesores and homeless camps before a revitalization this century converted much of it into magnificent parkland. ...

Don't get me wrong, this park ^ is beautiful, but it feels sort of gimmicky.

It has very little usable space. It is more of a place to "go see," and say you've been there than a real useable green space (to sit, or kick a ball, or have a bbq, or a birthday party, etc) for people who live in the area.

Also, because it is "the end of the line," while the path is lovely it seems a bit sterile.

A few years ago my daughter who lived in Manhattan for a decade took me for a walk along an old bit of raised rail turned into the High Line Park .  It certainly looked 'contrived', but it was being well used, as I see about 30 people on the Little Island picture above.  Having lived in NYC for a year myself, I cherished my time in parks where no car were 'in your face' - I often used the John Finley Walk to get to work - it was a sidewalk between the FDR Drive and the East River, but it made life in the City more livable.

High Line Park

How the giant trees got to New York’s new island park
Quote
Little Island, the city’s newest park, is perched over the Hudson River. When it opened, it was full of large, mature trees. What does it take to fill a park out with foliage?

Off the west side of Manhattan, sitting in the Hudson River, is a new New York City public park called Little Island. The $260 million pet project of businessman Barry Diller features 2.4 acres of tree-lined pathways, an amphitheater, and a food court. The idea for Little Island began nearly a decade ago, though it just opened to the public at the end of May. You’d be forgiven for thinking it’s been around longer. The park juts out of the river on concrete tulip-esque columns, and jutting out of the park itself is an array of trees—and not skinny saplings secured with stakes into the ground. These trees look as if they’ve already lived here for some time, and that was by design. …

Creating new, old-looking greenspace within a city isn’t easy.
Quote
“If that tree had not been planted immediately, its roots would dry out and it would suffer,” Nielsen explains. There’s still a chance something could happen to the trees in the park—an infestation, disease, a lightning strike—but luckily they are under a two-year warranty. “The trees are the single-largest investment of the entire landscape, and I think they’re also hugely visually important to the site, so their care and feeding, so to speak, is an extremely high priority.”

That is so very interesting!
Ireland is so close to 'mainland' Britain.
the absence of woodpeckers must affect the ecology of Ireland's woods.
I wonder what species has been filling the woodpecker niche?

A historical preference for fields? Most of the newer tree cover is relatively recent.


Forest cover is estimated to be at its highest level in over 350 years.

...

Nearly three-quarters of the stocked forest area is less than 30 years of age.

...

at 11.4%, forest cover in Ireland in 2020 was one of the lowest in the EU 27, where the average forest cover was 38.3%; worldwide forest cover was 31.1%

https://www.gov.ie/en/publication/57d2a-forestry-facts-and-news/

Most private planted forests are new so i think it is just finally becoming attractive enough for them.

Not sure if this is the right place for this, but apparently the tundra in NW Alaska is becoming "more livable" for trees...

These Trees Are Spreading North in Alaska. That’s Not Good
White spruce trees are expanding into the Arctic tundra with stunning speed, with potentially serious consequences both for the region and the world.
https://www.wired.com/story/these-trees-are-spreading-north-in-alaska-thats-not-good/

Quote
Writing this month in the journal Nature, Dial and his colleagues put hard numbers on what they discovered in the Alaskan tundra: White spruce, both as individuals and as a population, are growing exponentially there. The population is now moving north at a rate of 2.5 miles per decade, faster than any other conifer treeline that scientists have measured, in what should be one of the most inhospitable places on the planet for a tree.

Usually, spruce seeds don’t travel more than a few hundred feet from a tree. But Dial is finding young white spruce growing from seeds that must have traveled 5 to 7 miles—and over mountains, no less. The population isn’t so much moving north as it is leaping. “These new colonists, you’d think that they're beyond the treeline, they should just be struggling. But they're actually growing really rapidly,” says Dial. “They're happy as pigs in poop—they're just going gangbusters out there in the Arctic tundra and alpine tundra. They're way ahead. They're even doing better than the shrubs.”

Exactly why they’re doing so well demands more research, but Dial speculates that the colonists have access to untapped nutrients in the soil. By contrast, back at the treeline, existing generations of white spruce have already extracted the goodies from the soil, perhaps slowing their march. “If you want to study how forests are going to move, it's probably not appropriate to go to a treeline, because a treeline is where they're kind of stalled out,” says Dial. “If you want to figure out, ‘how can a business do better?’ you probably don't go study a struggling business. You go look for startups that are doing well.”

And, boy, business is booming for white spruce right now. Soil microbes in this part of the Arctic are providing a sort of stimulus package for them. The microbes multiply as the dirt warms, processing nutrients for the trees to use. “Obviously, warming is the driving factor—warmer conditions, longer growing seasons,” says macroscale ecologist Scott Goetz, who studies Arctic greening at Northern Arizona University but wasn’t involved in this new research. “So it's all become much more suitable, and I think nutrients are just part of the story.”

It feels a bit artificial. The original was posted somewhere in the Arctic subforum. Yes it is becoming more livable for these pioneer trees but overall that is bad because it is just a feedback in the climate system.

The woodpeckers are a sign of forest recovery so that hints as an actual improvement.

When a heatwave hits, temperatures in cities can become even more extreme as all that concrete and asphalt absorbs a ton of sunlight.

One Los Angeles neighbourhood is testing out a new strategy to keep itself cool from this phenomenon, called the “urban heat island” effect.

Pacoima, a community in the San Fernando Valley, is painting one million square feet of roads, playgrounds and basketball courts with a reflective paint. The paint doesn’t absorb as much heat as uncoated surfaces would, and project organizers hope that the effects can spread to cool down the whole neighbourhood.

On hot summer days, cities can get up to seven degrees Fahrenheit hotter than their surrounding areas, according to the US Environmental Protection Agency (EPA).

Even at night, long after the sun has set, cities can still be up to 5F hotter as absorbed heat radiates back out from roads, buildings and sidewalks, the agency adds.

The paint being used in Pacoima can reflect both visible light and infrared light - meaning heat, according to Fast Company.

Streets in the neighbourhood have been coated in a light-grey paint to bounce sunlight from the dark asphalt which can be a significant source of heat since darker colours absorb more heat than light ones.

The paint also comes in more colourful hues, and areas around a local park have been decked out in blue, white, yellow and brown. Different colours were used to delineate sections of basketball and tennis courts, as well as track and hopscotch courts.

...

Some initial measurements have shown promise. Bloomberg reports that an area of coated pavement was about 10F cooler than non-coated asphalt nearby, during one measurement in the neighbourhood.

That could make a significant difference. Standard pavement can reach up to 150F (67C) on a hot day, according to the EPA, meaning lots of extra heat seeping into the community.

I didn't post it because I think it's good.  Perhaps the far north is gradually becoming more livable for all sort of creatures, but that doesn't make it a good thing.  Personally, I need more sunshine than NW Alaska receives most of the year.

If it belongs somewhere else, feel free to move it or remove it, I missed the original.

That said, I found the part about the soil microbes was interesting.  The land is definitely adjusting to the changing climate.

I do not agree. The appearance of trees north of their past area means more trees which means more C sequestration. Gaia is trying to rebalance the C budget. We need many more trees up north

yep .. let nature do it;s thing as much as possible .. it isn't her that's f'ing things .
   
    Regarding my new neighbours , the great spotted woodpeckers . it could well be the improvement to the largely deciduous forest that has developed from an almost totally conifer plantation planted in 1958.
   I almost burned it down in '74 but declared myself the hero for beating it out :) , Lost some hedge , roasted hundreds of snails and scorched a few young trees . Phew .. hot work at 14 but huge relief . My dad told me later a neighbour had seen the whole thing ..
  Anyway , conifers were thinned several times and the central 2 ha are now all beech , oak , ash etc with a surround of mostly scot's pine . An attractive potential home for some woodpeckers . I'm looking forward to hearing them .
  Of course bird tables are an added attraction .

Also will be interesting to see if our overlapping visits by Black cap subspecies generate a new AYR resident subspecies . I never saw or heard one in my first 40 years , now I'm never out of earshot !

Bats .. just spent dusk watching my flying friends . It's the first time that I've seen pipistrelles here , while there have always been plenty of larger bats so more positives . I provide ideal conditions for billions of insects so although none nested , my skies are host to 100+ house martins pretty much all day as well as a lot of swallows , the adults raising their 3rd broods atm .

The young barn owls have gone quiet . All in all , a very dry year has not had much negative impact here .. most trees seem to have access to the water table through the limestone . A lot of apples on very healthy 100 yr old trees beside the old stone well .. water table has dropped @ 30 cm .. to @ 2 m .

No problem. The article gets a bit more exposure this way and it is interesting.   

Yes it is becoming more livable for these pioneer trees but overall that is bad because it is just a feedback in the climate system.

There are more trees growing there because it is warmer now. Snow melts earlier and growing season is getting longer even relatively far up north.

Trees in the arctic reduce albedo which is bad.

Oh and did you see how small they are? This tree is never going to compensate for all the much bigger trees that burn in Siberia and Canada a bit lower north.

If you would talk about a place like Ethiopia, and their dam. They started to fill the dam. And it did'nt created much problems downstream. So basically they could use some of that water every year. If you talk about the arid regions. And lets say you would make a network of pools, natural pools. You keep the farmland away from it, so it don't becomes a pool full with toxic algea. Maybe a few km forest near the pool. Just one pipe in , and one pipe out to supply smaller pools. What seeps in the ground you can pump up later when needed. Would that be possible to keep it going ? Or would the evaporation be so high that you lose so much of it ? If they let Egypt pay for their water, that would probably be the best guarantee for them to get it. And they could use the electricity from the dam in a productive way. It could be a big boost for the horn of africa. And that would lower the level of immigration to other places. And most of these arid places were forest before.

Biden administration moves to make conservation an equal to industry on US lands
By MATTHEW BROWN
Updated 11:32 AM MST, April 19, 2024

BILLINGS, Mont. (AP) — The Biden administration on Thursday finalized a new rule for public land management that’s meant to put conservation on more equal footing with oil drilling, grazing and other extractive industries on vast government-owned properties.

Officials pushed past strong opposition from private industry and Republican governors to adopt the proposal. GOP members of Congress said in response that they will seek to invalidate it.

The rule from the Interior Department’s Bureau of Land Management — which oversees more than 380,000 square miles (990,000 square kilometers) of land, primarily in the U.S. West — will allow public property to be leased for restoration in the same way that oil companies lease land for drilling.

The rule also promotes the designation of more “areas of critical environmental concern” — a special status that can restrict development. It’s given to land with historic or cultural significance or that’s important for wildlife conservation.

The land bureau has a history of industry-friendly policies and for more than a century has sold grazing permits and oil and gas leases. In addition to its surface land holdings, the bureau regulates publicly-owned underground mineral reserves — such as coal for power plants and lithium for renewable energy — across more than 1 million square miles (2.5 million square kilometers).

Interior Secretary Deb Haaland said the changes would “restore balance” to how the U.S. government manages its public lands. The new rule continues the administration’s efforts to use science to restore habitats and guide “strategic and responsible development,” Haaland said in a statement.

Environmentalists largely embraced the changes adopted Thursday, characterizing them as long overdue.

Trout Unlimited President Chris Wood said conservation already was part of the land bureau’s mission under the 1976 Federal Lands Policy Management Act. The new rule, he said, was “a re-statement of the obvious.”

“We are pleased to see the agency recognizing what the law already states — conservation is a vital use of our public lands,” he said.

But Republican lawmakers and industry representatives blasted the move as a backdoor way to exclude mining, energy development and agriculture from government acreage that’s often cheap to lease. They contend the administration is violating the “multiple use” mandate for Interior Department lands, by catapulting the “non-use” of federal lands — meaning restoration leases — to a position of prominence.

“By putting its thumb on the scales to strongly favor conservation over other uses, this rule will obstruct responsible domestic mining projects,” said National Mining Association President Rich Nolan.

The rule’s adoption comes amid a flurry of new regulations from the Biden administration as the Democrat seeks reelection to a second term in November.

Government agencies in recent weeks tightened vehicle emissions standards to cut greenhouse gas emissions, finalized limits on PFAS chemicals in drinking water and increased royalty rates for oil companies that drill on public lands.

About 10% of all land in the U.S. falls under the Bureau of Land Management’s jurisdiction, putting the agency at the center of arguments over how much development should be allowed on public property.

Wyoming Sen. John Barrasso, a staunch Biden critic, on Thursday said he will introduce legislation to repeal the public lands rule. The Republican lawmaker alleged it would block access to areas that people in Wyoming depend on for mineral production, grazing and recreation.

“President Biden is allowing federal bureaucrats to destroy our way of life,” he said.

A property rights group that often sides with private interests said the rule would help promote voluntary conservation efforts. It will allow ranchers and others who use public lands to work with private organizations to restore streambeds, improve wildlife habitat and remove invasive weeds, said Brian Yablonski with the Property and Environment Research Center.

Democratic Rep. Raul Grijalva of Arizona asserted that protecting public lands has wide support among the American people. Oil, gas and mining companies “have had the upper hand on our public lands for too long,” Grijalva said.

Restoration leases will not be issued if they would conflict with activity already underway on a parcel of land, officials said. They also said private industry could benefit from the program, since companies could buy leases and restore that acreage to offset damage they might do to other government-owned properties.

Those leases were referred to as “conservation leases” in the agency’s original proposal last year. That was changed to “restoration leases” and “mitigation leases” in the final rule, but their purpose appears largely the same.

While the bureau previously issued leases for conservation purposes in limited cases, it has never had a dedicated program for it.

Bureau Director Tracy Stone-Manning has said the changes address the rising challenges of climate change and development. She told The Associated Press when the changes were announced last year that making conservation an “equal” to other uses would not interfere with grazing, drilling and other activities.

Former President Donald Trump tried to ramp up fossil fuel development on bureau lands, before President Joe Biden suspended new oil and gas leasing when he entered office. Biden later revived the deals to win West Virginia Democratic Sen. Joe Manchin’s support for the 2022 climate law.

(this is pretty cool. A lot of the desert sw USA is "cow burnt". Cattle and sheep have mowed down almost all ground cover, causing lots of runoff. This fills small creeks with multiple feet of sand, destroying habitat on said seasonal creeks. Also with no rootlets, lots of sheet flooding causing massive dirt road damage. These repair costs get passed on to taxpayers everywhere. Almost all the ranching in the desert southwest ends up being net negative because of these costs. Many conservation groups have been trying to take over these $8-13? acre leases, to re-sow native grasses, and re-establish antelope herds, ground water recharge, riparian habitat, and native biomes.)
