World's oceans warming at increasingly faster rate, new study finds

Ocean water has absorbed more than 90% of the excess heat and nearly 30% of the carbon dioxide generated by human consumption of fossil fuels

The world's oceans are warming at a quickening rate, with the past 20 years accounting for half of the increase in ocean heat content that has occurred since pre-industrial times, a new study has found.

US scientists discovered that much of the extra heat in the ocean is buried deep underwater, with 35% of the additional warmth found at depths below 700 meters. This means far more heat is present in the far reaches of the ocean than 20 years ago, when it contained just 20% of the extra heat produced from the release of greenhouse gases since the industrial revolution.
