Amazon Deforestation Accelerating Towards Unrecoverable 'Tipping Point'


https://www.theguardian.com/world/2019/ ... ping-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.”

The whole reason I started this thread is we are already past the tipping points. Face it, the future Earth climte is not going to be like the climate of the 20th century where most of us grew up.

Oh sure, if you live in Tibet or the Andes mountain tropics you might not see much change, but pretty much everyone else won't be so lucky.

The Amazon will become a grassland instead of being a forest, based on climate projections. Whether humas rush the removal of the remaining forest at this point isn't going to change the ultimate situation. The same is probably true of the California Sequoia National Forest, as well as Alaska/Siberia/Canada. It really really can depress you if you love trees, but you have to think further ahead. Just as the current forests will go away or vastly change so will the vast areas now known as Tundra. In almost all of current Tundra lands forests used to prosper. On the yet another hand the great North American Breadbasket from Ohio to the Rocky Mountains is likely to convert to desert just as it was a few million years ago.

Pollen analysis of lake bed sendiments in the Amazon reveal that during the maximum glacial advance of past ice ages the Amazon was savanna grasslands with tropical forest remaining only in the riparian habitat of waterways.

The pulse back and forth between grassland and forest was part of a natural cycle. Whats happening now is a forced grassland during a time when we are at a glacial minimum. Who the hell knows what impacts this will have.

Biodiversity loss enormous, rainfall patterns greatly altered. Certain regions in Brazil and beyond suffering drought. Crop failures. What's missing is a rogue pathogen coming out of the Amazon, air born like the flu, lethality of Ebola and with the mutation rate of AIDS.

Why not with delayed onset of symptoms like AIDS?
Try imagine airborne Ebola like disease with latent period of 2-5 years. No cure and no vaccine.
Only faulty BRCA1 would provide natural protection. :-D

If such a pathogen came out most of people would believe that it was designed regardless of facts.

Really scary post on Arctic News.

The thing is it may very well be true.

Likely it will have no effect/impact because it is not a cause of climate change. The tail doesn’t wag the dog, climate change can cause deforestation, it’s difficult for a small amount of deforestation to result in any measurable climate change. The 3 football fields (soccer) per second of deforestation is 12,000 sq km per year. The Amazon rain forest is 5,500,000 sq km, the earth’s surface is 510,000,000 sq km. Amazon deforestation is minuscule to the solar energy absorbing surface of the earth and the CO2 exchange. It is also insignificant compared to the amount of reforestation happening around the world, we have a net increase in green.

A new study using data from NASA satellites shows that China and India, the two most populous countries in the world, are leading the increase in greening on land and concludes that the "effect comes mostly from ambitious tree-planting programs in China and intensive agriculture in both countries." The study was published on Monday in the journal Nature Sustainability.

The researchers found that the global green leaf area has increased by 5 percent since the early 2000s, an area equivalent to the Amazon rainforests. At least 25 percent of that gain came in China.

Cid may laugh last with his methane-bomb predictions (in spirit at least).

HALL OF SHAME:
-Short welched on a bet and should be shunned.
-Frequent-flyers should not cry crocodile-tears over climate-change.

Thanks for the laugh, jaw. Nothing like Chinese propaganda for a good chuckle! :)

"Global Times... is a daily Chinese tabloid newspaper under the auspices of the People's Daily newspaper, focusing on international issues from the Chinese government's perspective" (wiki) i.e. Chinese Communist mouth piece. I didn't realize you had such a deep love and respect for commies these days, jaw. That's kinda sweet! :) :)

Meanwhile, back on planet earth:

World losing area of forest the size of the UK each year, report finds


Chance of ending deforestation by 2030 seems lower than when pledge was made five years ago


...The New York declaration on forests was signed at the UN in 2014, requiring countries to halve deforestation by 2020 and restore 150m hectares of deforested or degraded forest land.

But the rate of tree cover loss has gone up by 43% since the declaration was adopted, while the most valuable and irreplaceable tropical primary forests have been cut down at a rate of 4.3m hectares a year...

World 'losing battle against deforestation'


A historic global agreement aimed at halting deforestation has failed, according to a report.


An assessment of the New York Declaration on Forests (NYDF) says it has failed to deliver on key pledges.

Launched at the 2014 UN climate summit, it aimed to half deforestation by 2020, and halt it by 2030.

Yet deforestation continues at an alarming rate and threatens to prevent the world from preventing dangerous climate change, experts have said.

The critique, compiled by the NYDF Assessment Partners (a coalition of 25 organisations), painted a bleak picture of how the world's forests continue to be felled.

Deforestation 'accelerating'

"Since the NYDF was launched five years ago, deforestation has not only continued - it has actually accelerated," observed Charlotte Streck, co-founder and director of Climate Focus, which co-ordinated the publication of the report.

The report says the amount of annual carbon emissions resulting from deforestation around the globe are equivalent to the greenhouse gases produced by the European Union.

On average, an area of tree cover **the size of the United Kingdom was lost every year between 2014 and 2018.
