January 2010 UAH Global Temperature Update +0.72 Deg. C
by Roy W. Spencer, Ph. D.
UPDATE (4:00 p.m. Jan. 4): I’ve determined that the warm January 2010 anomaly IS consistent with AMSR-E sea surface temperatures from NASA’s Aqua satellite…I will post details later tonight or in the a.m. – Roy

The global-average lower tropospheric temperature anomaly soared to +0.72 deg. C in January, 2010. This is the warmest January in the 32-year satellite-based data record.
The tropics and Northern and Southern Hemispheres were all well above normal, especially the tropics where El Nino conditions persist. Note the global-average warmth is approaching the warmth reached during the 1997-98 El Nino, which peaked in February of 1998.
This record warmth will seem strange to those who have experienced an unusually cold winter. While I have not checked into this, my first guess is that the atmospheric general circulation this winter has become unusually land-locked, allowing cold air masses to intensify over the major Northern Hemispheric land masses more than usual. Note this ALSO means that not as much cold air is flowing over and cooling the ocean surface compared to normal. Nevertheless, we will double check our calculations to make sure we have not make some sort of Y2.01K error (insert smiley). I will also check the AMSR-E sea surface temperatures, which have also been running unusually warm.
After last month’s accusations that I’ve been ‘hiding the incline’ in temperatures, I’ve gone back to also plotting the running 13-month averages, rather than 25-month averages, to smooth out some of the month-to-month variability.
We don’t hide the data or use tricks, folks…it is what it is.
[NOTE: These satellite measurements are not calibrated to surface thermometer data in any way, but instead use on-board redundant precision platinum resistance thermometers (PRTs) carried on the satellite radiometers. The PRT’s are individually calibrated in a laboratory before being installed in the instruments.]

So, interpretate your silence now as
a YES,
i.e. we donot really know exactly how much cooling and how much warming is caused by the carbon dioxide!
Definitely Not, you can interpret it as too busy clearing 15″ of snow off my driveway and dealing with a fallen tree limb.
You’re still wrong on the science and will be until you drop the stupid notion of reflection by CO2!
Sigh….
There are none so blind as those who donot want to see.;…
If you would read all of my writings in this post you would find out that a lot more snow is going to come your way in the years ahead, in fact I have already started praying that we will not fall into an LIA!
Enjoy your global “warming” while it lasts.
It was warmer???????? Maybe where they measure the temps – but it’s been the #30 coldest winter Iowa’s had since they started keeping records. That tops the #32 coldest that we had last year. We are definitely not getting any of this “global warming” here.
Ok, can someone please tell me precisely what the “global average temperature” is????
I only see “departure from normal” (which is a misnomer since no one knows what “normal” is – anything goes when it comes to both climate and weather)
Henry@allseasons
I stand under correction and I don’t know about the decimals, but I believe the average global temperature is 288 K (= 15 degrees C= 60 degrees F).
In fact, there really has not been that much global warming, in the past 15 years.
I suggest you look here to carry on that debate:

Probably not, on a thread this old. You could try at this most recent UAH post or at a newer one.
Thanks Henry and kadaka:)
