Dr. Roy Spencer has an essay below on sea surface temperatures starting to bottom out, but in addition to that, the UAH daily lower troposphere plot shows a sharp drop also.
As this graph of UAH TLT from D Kelly O’Day’s site shows, The current global anomaly is 0.044C – or very nearly zero. That’s a big drop from last month when we ended up at 0.60C.
Note the black dot, the value on 10-26-10. Click to enlarge the image.
Now compare that to Dr. Spencer’s Sea Surface temperature plot below.
Bottom Falling Out of Global Ocean Surface Temperatures?
by Roy W. Spencer, Ph. D.
Having just returned from another New Orleans meeting – this time, a NASA A-Train satellite constellation symposium — I thought I would check the latest sea surface temperatures from our AMSR-E instrument.
The following image shows data updated through yesterday (October 27). Needless to say, there is no end in sight to the cooling.
(Click on image for the full-size version).
Since these SST measurements are mostly unaffected by cloud cover like the traditional infrared measurements are, I consider this to be the most accurate high-time resolution SST record available…albeit only since mid-2002, when the Aqua satellite was launched.
I won’t make any predictions about whether SSTs will go as low as the 2007-08 La Nina event. I’ll leave that to others.
