The climatic extremes that occur in the Amazon rainforest directly affect those on the Tibetan Plateau, according to research by scientists who have established a connection.
More specifically, they warned that the Himalayan region, which is vital to ensuring water security for millions of people, is on the verge of a potentially catastrophic “tipping point.”

The climate change caused by human activities leads to often irreversible changes in crucial ecosystems and entire regions.
Areas particularly vulnerable to these climate disturbances include the ice caps, whose melting could raise sea levels by several meters, and the Amazon Basin, where tropical forests victimized by deforestation are at risk of converting to savannas. which will prevent them from fulfilling their role as carbon sinks on the planet.
But can a “tipping point” in one part of the world have a domino effect in another region? And recent research suggests that this is already the case.
Climate change in the Amazon basin is having an impact on the Tibetan plateau 20,000 kilometers away, Chinese, European and Israeli scientists guarantee in an article published in the journal Nature Climate Change earlier this month.
Scientists used global data on nearsurface temperatures over the past 40 years to identify climate links, from South America to southern Africa, then to the Middle East and finally to the Tibetan Plateau.
Computer simulations were then used to determine how global warming might alter these relationships over the long term through 2100.
From there, scientists found that when the temperature in the Amazon rises, temperatures in Tibet rise. And conversely, as precipitation increases in the South American rainforest, snowfall in the Himalayan region, sometimes referred to as “the third pole,” decreases.
