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.



Ole also shows below the Argo data for the 59 N, 30-0W transect. (On the map at the top, you can see this relates to the line from the Shetlands to just west of Iceland).

This particular section is deemed to be important because it sits across the main part of the North Atlantic Current.

Again we see a steep decline in the last few years. But significantly we can see the time depth diagram below as well.

What this shows clearly is that the cold has been building up from the bottom.

It has been claimed that “melting Arctic ice” is been responsible for colder SSTs. The ARGO data proves that this is not true.

We are reminded that it is the oceans and their cycles which dominate the Earth’s climate.

The AMO is continuing to flatline in positive territory, but are the OHC figures the first sign that things might be beginning to change?

    Reblogged this on Climatism and commented:
    North Atlantic ocean temps dropping rapidly, inline with atmospheric temps dropping rapidly, post El Niño.

    Meanwhile trace gas CO2 increases. Ergo, CO2 versus Temp correlation?

    Even though I cannot pretend to understand the oceans and ice information it is obvious that the oceans are the drivers of the climate. The obsession with linking climate to air heating (due to carbon dioxide) is slowly being shown to be incorrect.

    It would be most amusing to invert these graphs and send them to the Gruniad and Big Brother Corp, they would create fantastic fear headlines.

    Here in Singapore area, people are saying “ooh weather is unusual’s rained most days this last month (hence i’s cooler) , then they say ..ooh Climate Change” ..
    I ask “What about El Nino /La Nina ?
    They reply “I’ve nevr heard of it “

    It’s going to be very interesting to see what effect this cooling has on certain fish stocks in the North sea and North Atlantic. It was claimed by the AGW zealots that global warming had driven some fish northwards seeking colder waters. Many fishermen on the other hand claimed this was just part of a natural oceanic cycle.

    I know who my money would be on.

      North Sea stocks of Gadoid Fish were at their highest since 1945 in the late 1960s early 1970s,the Gadoid Outburst, which coincides with the coldest period in the Global monthly heat content anomaly (GJ/m2) in the uppermost 700 m of the North Atlantic (60-0W, 30-65N) ocean since January 1955 chart above. Most theories are that the decline in the herring population was a cause, but it is just as likely that cooler water had a major influence perhaps also affecting the herring population at a time of over fishing.

        Oh well, the Cod are back….

    The Argo time depth diagram is quite striking. Pity we don’t have any previous to compare, but it does demonstrate the level of our knowledge/comprehension – the lack of it!

    Yet it does not stop folks from being absolutely certain about what the future holds, whilst remaining at a loss about the present.

    Still it is quite a significant change. One can only assume the data has been double checked? Or is it possible there is a data collection/processing/equipment malfunction yet to be discovered?

    Ho hum, time will tell……

    Where does that heat go? I thought that the ocean had an enormous heat capacity.

      Your statement in the second sentence IS the answer to your question in the first sentence.

    Just like in the movie “The Day After Tomorrow”! We are doomed!!

    I just rented out that silly movie over this past weekend. Quite a coincidence!
