Global warming pause.

There have been several articles about the pause in global warming and these have been instigated by some new research which shows that the heat is going into the Atlantic. In fact it said that the Pacific Ocean could not absorb the sufficient heat to account for the pause. The researchers looked at the records from the Argo floats and found that the extra heat was going into the Atlantic.

93% of the world’s heat is stored in the oceans so it has an enormous effect on the atmospheric surface temperature anyway and our records of the oceans are abysmal. The Argo floats are doing great stuff but they have only been in operation ten years and only record the top 2000 metres, which is not much to go on.

A quick look at the NASA temperature records since 1880 shows that there have been two previous pauses and the last one lasted thirty years so we have a bit to go yet.

The pauses are caused by heat going into the ocean deeps from the Gulf Stream, Southern ocean and Alaskan current and coming out decades later.
In the meantime the heat and the ocean acidity that travels with it are doing untold damage in our oceans.

Thanks for the interesting piece on ocean warming and argo. News of prototypes launched off New Zealand's coast (developed by Scripps Institute) that can measure temps down to the sea bottom. We should build up a lot more additional information over the next few years.

There is a good piece on the Argo website about the first trial launch. We need to know what is going on down in the deep oceans.
