An international team of climate scientists has found evidence suggesting that deforestation in the Amazon rainforest is influencing weather in Tibet, more than 15,000 kilometers away. In their paper published in the journal ...
Temporarily overshooting the climate targets of 1.5–2 degrees Celsius could increase the tipping risk of several Earth system elements by more than 70% compared to keeping global warming in line with the United Nations ...
