Extreme heat in oceans ‘passed point of no return’ in 2014 | oceans
Extreme heat in the world's oceans passed the “point of no return” in 2014 and has become the new normal, according to research.Scientists analyzed sea surface temperatures over the last 150 years, which have risen because of global heating. They found that extreme temperatures occurring just 2% of the time a century ago have occurred at least 50% of the time across the global ocean since 2014.In some hotspots, extreme temperatures occur 90% of the time, severely affecting wildlife. More than 90% of the heat trapped by greenhouse gases is absorbed by the ocean, which plays a critical role in maintaining a stable climate.“By using this measure of extremes, we've shown that climate change is not something that is uncertain and may happen in the distant future – it's something that is a ...
