The Amazon rainforest is reaching a critical “tipping point,” according to researchers, beyond which it may no longer be able to recover from events such as droughts and wildfires.⁠

The result, a new analysis of satellite data shows, would be permanent loss of much of the rainforest, with devastating consequences for climate change and biodiversity.⁠

The study, published Monday in the journal Nature Climate Change, looked at satellite data of vegetation in parts of the Amazon that have not been altered by human activities such as logging, from 1991 to 2016. It found that, since the early 2000s, areas that suffered droughts or wildfires have been taking longer to recover than before, with drier areas of the forest experiencing the greatest decline.⁠

The study’s authors warned that if climate change continues, some of these areas may stop growing back as rainforest altogether, a phenomenon known as “dieback.” This could have dramatic worldwide consequences, as it would mean much less carbon dioxide — the most prevalent greenhouse gas that causes global warming — would be absorbed by growing trees.⁠

“Many researchers have theorized that an Amazon tipping point could be reached, but our study provides vital empirical evidence that we are approaching that threshold,” said coauthor Niklas Boers, a professor at the Technical University of Munich in Germany. ⁠

This threshold has not yet been crossed, however, meaning that if governments take swift action to reduce emissions it could still be avoided.⁠

  2. They sure use the words may, possibly, possible and could when talking about climate change. That “may” be the reason people are so slow to believe the science is based on theory and a hunch

  3. I would advice and recommend @maria_jason_fx for anyone who is seeking to migrate to 100% better dream a good life
