OCEAN SURFACE TEMPERATURES: HOW LOW WILL THEY GO?
…La Nina Uncancelled
La Nina Uncancelled

A U.S. government weather forecaster raised its outlook on Thursday for La Nina conditions in the coming months, saying the weather phenomenon is likely to develop in the Northern Hemisphere fall and favored to persist into the winter 2016-17. The Climate Prediction Center (CPC), an agency of the National Weather Service, in a monthly forecast pegged the chance of La Nina developing this fall at 70 percent, versus a likelihood of neutral conditions forecast last month.

Powerful Natural Oceanic Factor Confirmed ….Global Surface Temperatures Continue Their Fall
…North Atlantic Ocean Heat Content Dropping Rapidly
Ole Humlum’s excellent site, Climate4you, has just published the latest Ocean Heat Content data, now up to March 2016. They show some interesting things happening in the North Atlantic.
First, let’s look at the area highlighted below:
Map showing the North Atlantic area within 60-0W and 30-65N, for which the heat content within the uppermost 700 m is shown in the two diagrams below.
Global monthly heat content anomaly (GJ/m2) in the uppermost 700 m of the North Atlantic (60-0W, 30-65N) ocean since January 1955. The thin line indicate monthly values, and the thick line represents the simple running 37 month (c. 3 year) average. Data source: National Oceanographic Data Center (NODC). Last period shown: January-March 2016. Last diagram update 7 June 2016.
We have become familiar with the cold blob, which has developed at the ocean surface in the northern part of the North Atlantic during the last couple of years, but it is evident that it has been getting much colder below the surface as well, down at least to 700 m. Temperatures are now back down to where they were in the early 1990s.
(It is also worth noting that the 1970s marked the coldest period in the record). Unfortunately we don’t have data for the warm 1930s and 40s.

In contrast, our satellite analysis has 2015 only third warmest which has also been widely reported for weeks now. I understand that the RSS satellite analysis has it 4th warmest.

– Land measurements …that thermometers over land appear to have serious spurious warming issues from urbanization effects. Anthony Watts is to be credited for spearheading the effort to demonstrate this over the U.S. where recent warming has been exaggerated by about 60%, and I suspect the problem in other regions of the global will be at least as bad. Apparently, the NOAA homogenization procedure forces good data to match bad data. That the raw data has serious spurious warming effects is easy to demonstrate…and has been for the last 50 years in the peer-reviewed literature….why is it not yet explicitly estimated and removed?
– Ocean Measurements …that even some NOAA scientists don’t like the new Karlized ocean surface temperature dataset that made the global warming pause disappear; many feel it also forces good data to agree with bad data. (I see a common theme here.)
– El Nino …that a goodly portion of the record warmth in 2015 was naturally induced, just as it was in previous record warm years.
– Thermometers Still Disagree with Models …that even if 2015 is the warmest on record, and NOAA has exactly the right answer, it is still well below the average forecast of the IPCC’s climate models, and something very close to that average forms the basis for global warming policy. In other words, even if every successive year is a new record, it matters quite a lot just how much warming we are talking about.…

How accurate are those estimates of ocean warming? ‘Margin of error’ may be larger than temperature change
…Southern Ocean back in business as a carbon sink (models were wrong)
The Southern Ocean absorbs 40% of the global oceanic uptake in CO2. For most of the last ten years researchers thought it was weaker, or at “saturation” point and not able to absorb more CO2. Instead, it looks like it has been absorbing more again and by the year 2010 was back up to full power. This means there was a lot more natural variation than scientists (and their models) thought.The GCM’s are meant to be coupled ocean and atmosphere models, but they don’t understand the ocean part.
Back in 2007, New Scientist declared the slowdown has “far reaching implications”, things were worse than the IPCC’s projections. Things were 20 years ahead of the IPCC’s schedule and it was “scary”:…
