A comphrehensive comparison of GISS and UAH global Temperature data

Part 1 of Comparison of GISTEMP and UAH MSU TLT Anomalies

Guest Post by Bob Tisdale

I originally started this comparison by looking at the differences between OI.v2 SST and the UAH MSU Lower Troposphere Temperature (TLT) anomalies for the same ocean segments. Since OI.v2 SST data has been used by GISS for their GISTEMP product since December 1981, I decided to add another comparison: GISS Land Surface Temperature (LST) versus UAH MSU TLT for the same continental land segments. Then I added one last comparison, which is the subject of this post.

Note 1: The data illustrated in the following graphs are as I downloaded them from the KNMI Climate Explorer website. I made no effort to offset either dataset in the comparative graphs so that the two curves rested on one another. The graphs will show that GISTEMP anomalies are higher than UAH MSU TLT anomalies. This is a function of base years. Focus on the trends and the shapes of the curves, not the location of the curves.

Figure 1 is a comparison of Global GISS Surface Temperature (GISTEMP) and UAH MSU Lower Troposphere Temperature (TLT) anomalies. Both datasets have been smoothed with 12-month running-average filters.

Pelosi concedes ‘not enough votes to pass global warming bill’

24 06 2009

If any WUWT readers have moderates in their congressional district, now is the time to make your opinions known.

May I suggest that you send your congressional representative this story with a request to read it on the floor. And while you are at it, the EPA shenanigans and my surfacestations report.  – Anthony

House Democrats unsure of global warming bill’s passage

WASHINGTON (CNN) – House Democratic leaders are furiously lobbying their members and moderate Republicans to support a landmark energy bill in the face of resistance from some conservative members of their own party, and staunch opposition from the GOP — roadblocks that are making it difficult to find the 218 votes necessary to pass the measure, according to Democratic leadership aides.

A vote on the Clean Energy and Security Act, which would restrict emissions of green house gases and require use of alternative energy in an effort to slow the effects of global warming, is scheduled for Friday.

The legislation’s lead sponsors held a pep rally outside the Capitol on Wednesday to whip up support for the legislation’s passage. Read the rest of this entry »

The EPA suppresses dissent and opinion, and apparently decides issues in advance of public comment

24 06 2009

The EPA apparently doesn’t care about any negative comment of their GHG Endangerment findings, even internally, so the exercise in Democracy we did yesterday apparently was for naught.

“The time for such discussion of fundamental issues has passed for this round. The administrator and the administration has decided to move forward on endangerment, and your comments do not help the legal or policy case for this decision… I can only see one impact of your comments given where we are in the process, and that would be a very negative impact on our office.”

- Internal EPA email, March 17th, 2009

The Competitive Enterprise Institute (CEI) has caught EPA administration red-handed in concealment of internal dissent as well as apparently proceeding with plans in advance.

From this PDF circulated today by CEI, here are the points:

NCDC writes ghost “talking points” rebuttal to surfacestations project

24 06 2009

UPDATE: The “ghost author” has been identified, see the end of the article.

When I first saw it, I laughed.

When I saw the internal memo circulated to top managers at NOAA, I laughed even more.

Why?  Because NOAA and NCDC are rebuking an analysis which I have not even written yet, using old data, and nobody at NOAA or NCDC  had the professionalism to put their name to the document.

First let’s have a look at the National Climatic Data Center’s web page from a week ago:

ncdc_web_page_061209

I was quite surprised to find that my midterm census report on the surfacestations.org project evoked a response from NCDC. I suppose they are getting some heat from the citizenry and some congress critters over lack of quality control. I was even more surprised to see that they couldn’t even get the title right, particularly since the title of my report defines most of what NCDC is all about; Surface Temperature Measurement.
