AMSRE Global SST down – near zero – trend since 2002 also down

While we have one blog post that shows OHC disappearing due to an adjustment by KNMI, Ocean Heat Content: cooling gone today with new adjustment, global sea surface temperatures are telling another story. That story is that our trend is down since 2002. You wouldn’t know it though to look at this NOAA chart.

Global Average SST Update to October 14

Since the global average sea surface temperature (SST) anomalies (departures from average) hit a peak a couple of months ago, I thought it would be a good time to see how they are progressing. Here’s a plot of running 11-day SST anomalies for the global oceans (60N to 60S latitude):

AMSR-E-SST-thru-10-14-09

As can be seen, at least for the time being, temperatures have returned to the long-term average. Of course, this says nothing about what will happen in the future. I have also plotted the linear trend line, which is for entertainment purposes only.

The SSTs come from the AMSR-E instrument on NASA’s Aqua satellite, and are computed and archived at Remote Sensing Systems (Frank Wentz). I believe them to be the most precise record of subtle SST changes available, albeit only since mid-2002.

Could someone explain this in relation to what made news yesterday.
— Globe simmered in September —
—> http://tr.im/BZbs
I am hard pressed to explain which temperature record is relevant. You look at the trend of satellite records and they are up,flat,down trend depending on the altitude of the record, you have the ground stations record (with or without cherry picking, with or without “contamination”) going all over the place trend wise. And now, here we talk about the surface ocean temperature being the most “accurate” to “show a trend”.
Is there a good resume somewhere to get started on all those different data sets, what they mean, how good or bad they are?
Thanks, Simon

“global sea surface temperatures are telling another story. That story is that our trend is down since 2002. You wouldn’t know it though to look at this NOAA chart”
Err, maybe because the chart you showed wasn’t global, try this one instead http://www.osdpd.noaa.gov/data/sst/anomaly/2009/anomnight.10.15.2009.gif
Notice how the cherry picking missed out the cold SST anomolies, or was it a genuine mistake, the kind of mistake you are so quick to damn on this site.
I haven’t seen such sloppy reporting as this since the Daily Mail blunder (US records V global).

I have tracked the particular SST events that lead to global cooling. Ocean up welling from the deep colder ocean currents in the Southern Hemisphere and associated cooling of the Southern Hemisphere SST were the earliest signs . [ SEE Professor GRAY’s papers ] Global temperature anomalies could be still rising while this is happening initially. Eventually the Northern Hemisphere SST anomalies will also start to decline The Southern Hemisphere SST has been declining now for three months in a row. If this continues for another 6 months or so watch for most of the other ocean SST’s anomalies to decline as well and to start to go cooler. We got a brief snapshot of this in September. AMO, AMO, and NAO will all to go cool on an annual basis and a drop in global temperatures will be clearly evident as a LA NINA replaces the current weak El Nino that is struggling to start. I see a possibilty of this happening in 2010.

The apparently opposite trends of OHC and SST anomaly are still confusing for me.
OHC is the amount of heat stored or present in the oceans above the thermocline which in most places is hundreds of meters deep.
SST is the temperature of the ocean at the surface.
In a stable climate OHC and SSTs will move in opposite directions. Increasing SSTs means more heat lost from the oceans and declining OHC. And increasing OHC for decreasing SSTs

I’ve been watching Unisys daily all summer, and it’s been showing an enlargement of the cool anomalies in the southern oceans but growing warm anomalies in the Atlantic,north of the equator. Nothing at all like the maps at the begining of this post.

Isn’t the problem of the NOAA chart the reference period for the anomaly?
Roy Spencer uses the term ‘return to the long term average’ but surely he is meaning the average of the Aqua period instrumentation from 2002. NOAA will be using the long term mean over several decades – as does Hadley (1961-1990). If you do that you get 3 C anomalies for the current decade – especially in northern oceans in the Hadley set because the base period includes the trough of 1960-1975 and excludes the Arctic peak of 1930-1940 which was also general in the northern hemisphere.
There is value in the graphic from 2002 – it shows that ‘global warming’ as driven by GHGs is not powerful enough to over-ride the natural variability (cycles) – and the reverse may be happening (which I think is the case – having concluded from the satellite data on radiation flux to the ocean surface that at least 80% of the ocean warming can be put down to thinning clouds from 1980-2000 (it is still an open question among open scientific minds – for example, Takmeng Wong at NASA – and I recommend:
http://eospo.gsfc.nasa.gov/eos_observ/pdf/Jan_Feb08.pdf
for a discussion of whether thinning cloud is a consequence of the GHG warming or cause of the ocean warming that has been mistaken for the GHG fingerprint
In my mind, the current cooling or flatline, points toward the latter. But GHG advocates can point out that the decade 2000-2009 is still warmer than the decade 1990-1999, and that was warmer than 1980-1989
we really need a better handle on the recovery from the Little Ice Age – long term trends and the long cycle of 800/400 years on top of which these shorter cycles of the PDO/AMO/AO and ENSO are peaking.

The current West to East equatorial trade winds need to turn around and head East to West for La Nina to return. The wind velocity we have now is barely discernible using the little arrows. There are occasional westerly wind bursts near the western side (Indonesia) of the Pacific that keeps this El Nino alive. I am waiting for the wind to blow the other way. As soon as that begins to happen, I will predict a La Nina.

David, You probably call a teeter-totter a see-saw. May be other names for this childhood playground item.

You might know a teeter totter by the name “sea saw”. It is a long board just wide enough to set on both ends that has been balanced on a raised structure at the middle fulcrum point. Then you sea saw or teeter totter up and down. When one end goes down, the other end goes up, along with you. Then you go down and the other child goes up.

Federal Agency Honesty in Forecasting Award:
(from the Staten Island Real-Time News)
http://www.silive.com/news/index.ssf/2009/10/national_weather_service_predi.html
“National Weather Service Predicts That Winter Weather Will Be Unpredictable”
WASHINGTON — The National Weather Service’s prediction for winter weather in the Northeast is that it can’t easily be predicted.
The federal agency is forecasting equal chances for above-, near- or below-normal temperatures and precipitation, which differs from AccuWeather’s prediction yesterday of a snowy and cold winter here.
Meanwhile in Pennsylvania (from the Philadelphia Inquirer):

I’m hearing arguments that ocean warming has turned deep; that surface measures are no longer applicable.
I’m skeptical since there is no recent sea level rise. Guessing it’s yet another global warming oh wait climate change oh wait air temp oh wait ocean temp oh wait deep ocean temp change because the facts keep not supporting their beliefs.
Anyway, anyone have any hard data on deep ocean non-warming?

Doug Jones and Mark Baker: Mark you asked, “What happened in 2007 to cause that huge downturn?” and Doug replied, “Mark, are you forgetting that a large amount of ice was blown out of the Arctic to melt in the North Atlantic? Probably took a year for this large extraction of heat from the Atlantic to flow through into the general SST averages?”
The reason for the drop in 2007 is the significant 2007/08 La Nina, as note above by Juraj V:
http://i37.tinypic.com/5vwqhd.png
Also as M White replied, Dr Spencer noted a significant increase in cloud cover in 2007.
http://wattsupwiththat.com/2009/09/26/the-2007-2008-global-cooling-event-evidence-for-clouds-as-the-cause/
Seeming to contradict this, a La Nina causes a decrease in cloud cover over the tropical Pacific, which is what recharges the ocean heat content there for the next El Nino (the minor El Nino we’re experiencing now), but the tropical Pacific is not the globe, so the global drop in cloud cover and the La Nina combined to drop the global SST anomalies.
With respect to your ice melting theory, Doug, the Arctic SST anomalies do not show it.
http://i33.tinypic.com/11kw3s7.png
A decrease in ice cover yields more solar input to the ocean, which raises SST anomalies, which melts more ice…
The SST anomalies of the North Atlantic also don’t agree with your theory:

I recently came across an interesting report by the USGS, which looks at cosmic rays, solar wind, ocean heat transport, and climate.
Solar Activity and Regional Streamflow:
Kansas District, U.S. Geological Survey
AUTHOR: Charles A. Perry, Research Hydrologist
Variations of Solar Activity Affect Regional Hydro-climate
http://ks.water.usgs.gov/waterdata/climate/
This research focuses on the hypothesis that variations in solar activity affect regional streamflow. Variations in solar activity may control the amount of energy that reaches the Earth’s surface. These variations in solar energy may help create ocean temperature anomalies that can persist for years and move with the ocean currents. The ocean temperature anomalies can have an effect on meteorological factors such as atmospheric vorticity and moisture, both important for precipitation formation. Varying amounts of precipitation controls the regional hydrology including streamflow, groundwater, and lake levels.

Please take a time to observe the above NOAA chart in detail, take then into account that in spite of this agency tendency to depict temperature anomalies in very intense orange and red colors, this time show not only blue but BLACK color, right in the equator line (the sea in front of Ecuador country, east pacific coast, Nino 1+2 area) , and that is a -5 degrees centigrade anomaly!
Don´t forget these are the early signs of the new minimum (Landsheidt, Jose or Eddy´s)
