Swift global action to reduce greenhouse gas emissions could prevent the “abrupt” collapse of ecosystems, which may otherwise begin within the next few decades, a study finds. The research, published in Nature, finds that uncontrolled climate change would see tropical ocean ecosystems exposed to potentially catastrophic temperature rise by 2030. By 2050, tropical forests could also face such conditions. By comparison, limiting global warming to below 2C – the goal of the Paris Agreement – could delay the date of exposure by up to six decades, according to the research. The results “show very clearly that it is not too late to act and the benefits of acting now will be massive”, a study author tells Carbon Brief.
