UPDATE – see new graph of global ∆T for the past year below. There has been a global drop in temperature of 0.63 degrees Centigrade in the past 12 months.
Of course we already have had a heads up from all the wire reports around the world talking about the significant winter weather events that have occurred worldwide in the last month, but until now, there hasn’t been a measure of how the planet was doing for the winter of 2007/2008.
Remote Sensing Systems of Santa Rosa just posted the latest MSU (Microwave Sounder Unit) data.
January posted a -.08°C near global anomaly between -70S and 82.5N latitude (the viewshed of the satellite sounder). That makes it the coldest month since January 2000, and the 2nd coldest January for the planet in 15 years. Both northern and southern hemispheres posted negative anomalies of -.120°C and -.038°C respectively, happening for the first time since January 2000.
The United States posted a -.557°C anomaly for January 2008 and a -0.196°C anomaly for December 2007.
Here is the raw anomaly data for January 2008
| Year | Month | -70.0/ 82.5 | -20.0/ 20.0 | 20.0/ 82.5 | -70.0/ -20.0 | 60.0/ 82.5 | -70.0/ -60.0 | CONUS | 0.0/ 82.5 | -70.0/ 0.0 |
| 2008 | 1 | -0.080 | -0.188 | -0.063 | 0.025 | 0.288 | -0.833 | -0.557 | -0.120 | -0.038 |

Here is my plot of the raw, unedited Global anomaly data (-70S to 82.5N) supplied by RSS per month. Note that the anomaly trend between late 2007 and early 2008 is quite steep and that the period leading up to 2008 is relatively flat.

UPDATE:
I decided to plot a magnified graph to show the global change in temperature over the last year from January 2007 to January 2008, the ∆T of -0.629°C is quite significant for a 12 month period, rivaled in the last 10 years only by the 1998 El Nino warming peak.

Probable cause– [Una] Niña muy grande. It looks like we may have a PDO shift as well. But as some say, trying to correlate such things is a “fools errand”. But, judge for yourself.

We live in interesting times.

So Timmy, did global warming end in 1998, or did global warming end in 2008?
I’m still curious.
Never mind the warming vs. cooling debate…let’s get to the real question.
“If there is Global Warming money to be made via Carbon Offsets/Hybrid Cars/Energy Star Appliances/Compact Flourecent Lights/etc, what is the value stream associated with Global Cooling?”
2007, colder than 2006! (but co2 increased in atmosphere…). Kyoto is one of the biggest lies of the History. U.N. promoves the GLOBAL ECOSUBMISSION / ECOBORREGUISMO. Thanks. 05/04/08
I don’t believe that a century even constitutes a trend. Look at the Medieval warm period and little ice age. They lasted 300+ years. When you see the graphs of the Vostok core data they neglect to tell you that the samples are 3-6000 years apart. How many warm and cold periods could there have been within those missing samples? Now we’re concerned with a 100 year trend?
Even the temps during the little ice age and Medieval warm period are derived from proxy data. Any data that is measured directly from modern instruments should never be graphed against proxy data to begin with. What is the margin of error for proxy data?
