Att: Fellow tree Huggers.
From Africa’s Baobabs To America’s Pines: Our Ancient Trees Are Dying.
https://www.huffingtonpost.com/entry...b07cb1712d8ea1
Old postcards show North American redwoods large enough for cars to drive through, thousand-year-old kauri trees in New Zealand with trunks the size of tanks, and European oaks older than the Roman empire with branches covering half a football field.
Some of these monumental trees are still alive, but scientists say that the world’s oldest and largest trees are dying out fast as climate change attracts new pests and diseases to forests, and settlements and new roads fragment ecosystems.
New research published in Nature Plants records that nine of the world’s oldest 13 baobabs and five of the six biggest ones, have partially or completely died in the last 12 years. The Romanian and South African researchers involved in the study speculate that repeated droughts, linked to climate change, may be responsible, but they want more research.

Exactly, everything living must eventually die.
From the article:
The Romanian and South African researchers involved in the study speculate that repeated droughts, linked to climate change, may be responsible, but they want more research.
Note the words "speculate" and "maybe". If one pays attention they will notice every time the effects of so called climate change are discussed words admitting to basing everything on theory and guesswork are obvious. My favorite example are how all over the place the prediction of sea level rise by the magic year of 2100 are. I have seen that vary from 5 inches to 15 feet.
Funny how every plant or animal that goes extinct is now man's fault when plants and animals came and went long before man showed up.

It is more complex than climate changing forests. Deforestation affects climate and the cycle is continuous.
Climate Change and Tropical Forests
https://globalforestatlas.yale.edu/c...opical-forests
In just the Amazon basin, studies estimate that forests contain 90-140 billion tons of carbon, which could be equivalent to 9-14 decades of human carbon emissions. Previous statements by the IPCCC estimated tropical deforestation and land use change to contribute about 20% of global carbon emissions, although more recent studies have placed this percentage closer to 10%. Nevertheless, carbon emissions from deforestation remain significant, a primary motivation behind the REDD+ mechanisms as an international climate change mitigation program. At the smaller level, forests affect local climate patterns; trees transpire water, so deforestation can reduce rainfall and contribute to desertification.

C'mon now! Get real. Everyone knows that old things don't die.
And as for droughts, they have only been with us since the dawn of time.

It may come down to choosing between man and
trees.
There are ways to lessen our footprint overall, but since the industrial revolution and increase in population, humans impinge on forests to a much greater degree.
Deforestation affects climate change and the older trees that are dying are all parts of forests. So....
Deforestation and Climate Change
http://climate.org/deforestation-and-climate-change/
Agriculture
Agriculture is one of the most significant causes of deforestation.
Raising Cattle
Cattle ranching has a massive impact on forests around the world, particularly tropical rainforests like the Amazon.
Logging
Logging is also a common cause of deforestation as trees are cut down to use for paper products.
Burning biomass
on such a large scale comes with many consequences. It is estimated that the total amount of biomass burned by humans make up a whopping 90% of the total number, where natural fires are only around 10%. According to NASA

wow imagine that, someone finding another way to dupe the country for research dollars . It's a new angle so eligible for more free cash

I'd be willing to bet that no one on this forum has cut down a tree in a South American rainforest. I think you are barking up the wrong tree.

Amazon deforestation is the most extreme. Deforestation happens all over. But I titled this thread Tree-Huggers. If I wanted tree swingers instead, I would have titled it appropriately.

These old trees are not dying - they are committing suicide because hcap and his elk keep barking up them and they are tired of the drivel!

No, haven't seen the elk all day.
Wonder what they are up to?
