A new atmospheric pathway

More tipping points than we thought:

Trees set ablaze in Brazil’s Amazon rainforest could contribute to melting glaciers in the Himalayas and Antarctica because distant ecosystems essential to regulating the Earth’s climate are more closely connected than previously thought, new research has found. 

Scientists have discovered a new atmospheric pathway that originates in the Amazon, runs along the South Atlantic, then across East Africa and the Middle East until it reaches central Asia, according to a paper published this month in Nature Climate Change. That connection, which stretches 20,000 kilometers (12,400 miles) across the globe, means that when the Amazon warms, so does the Tibetan Plateau, whereas the more it rains in the Amazon, the less it rains in Tibet.

So Bolsonaro sealed Tibet’s fate and thus much of Asia’s along with Brazil’s.

The study is among the first to investigate the interaction between ecosystems at risk of reaching a climate tipping point — a point of no return that would transform them irreversibly. More significantly, the newly-discovered pathway suggests that the collapse of one ecosystem could destabilize others too, leading to a cascade of tipping events across the planet.

Scary enough yet?

The latest report by the UN’s Intergovernmental Panel on Climate Change saw an increased probability that the Amazon will cross a tipping point. The question now is what that might mean for the Himalayas, one of the world’s great reserves of fresh water, which is already seeing unprecedented glacial melt. 

Just India, Pakistan, China – no biggy.
