Missing heat 2000-2009 indeed deeper in ocean, says NCAR model

As a regular of Bitsofscience.org you may recall a publication on ocean warming [between 2003-2010] in Geophysical Research Letters from last July. That one was little-noticed by the world’s media, but now its findings may receive more attention, as an … Continue reading

Lull in upper ocean warming explained through ENSO – warming trend continues

Shortly after an El Niño event there is elevated heat exchange from the upper ocean layers to the cosmos over the tropical Pacific Ocean. In the North Atlantic Ocean, variations in the ocean circulation affect the heat exchange to the … Continue reading

First proof ocean CO2 uptake has started to slow down

From raw measurements we know that in recent years the oceans seem to take up a smaller percentage of the CO2 we emit. Analysing available data a group of three researchers finds in part of the North Atlantic this is … Continue reading
