Extreme heat in oceans ‘passed point of no return’ in 2014

Formerly rare high temperatures now covering half of seas and devastating wildlife, study shows

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 analysed 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.
