Accurate Space "Thermometers" Stratosphere's Coldest Month Measuring Temperature from Space 1998 Temperature Trends Interactive Temperatures & Vorticity Temperature Anomaly Sources GHRC UAH GHCC Home	Globally-Averaged Atmospheric Temperatures Global Warming Debate Continues. . . The figure above shows the monthly temperature deviations from a seasonally adjusted average for the lower stratosphere - Earth's atmosphere from 14 to 22 km (9 to 14 miles). Red is an increase in the temperature from the average, and blue is a decrease in temperature. The large increase in 1982 was caused by the volcanic eruption of El Chichon, and the increase in 1991 was caused by the eruption of HREF="http://volcano.und.nodak.edu/vwdocs/volc_images/southeast_asia/philippines/pinatubo.html">Mt. Pinatubo in the Philippines. November 2000 was the coldest month on record for stratospheric temperatures. This chart shows the monthly temperature changes for the lower troposphere - Earth's atmosphere from the surface to 8 km, or 5 miles up. The temperature in this region is more strongly influenced by oceanic activity, particularly the "El Niño" and "La Niña" phenomena, which originate as changes in oceanic and atmospheric circulations in the tropical Pacific Ocean. The overall trend in the tropospheric data is near zero, being +0.04 C/decade through Feb 2002. Click on the charts to get the numerical data. Surface thermometer measurements indicate that the temperature of the Earth is warming, while the satellite data show long-term cooling trends. These differences are the basis for discussions over the existence and magnitude of any global warming the Earth may be experiencing as a result of human activity. This page, updated monthly, will continue to provide the latest temperature measurements of various layers of the Earth's atmosphere from space. We have a Java-based tool that allows you to interact with the Global Temperature Variations Data Set. Using this tool you can examine temperature variations from average at single locations on the globe or you may look at region averaged values. You can examine atmospheric temperature features for both the lower troposphere and the lower stratosphere in either degrees Fahrenheit or degrees Celsius. The data used were obtained by the National Oceanographic and Atmospheric Administration TIROS-N satellite, and interpreted by scientists Dr. Roy Spencer (University of Alabama at Huntsville) and Dr. John Christy (University of Alabama at Huntsville) at the Global Hydrology and Climate Center (GHCC), a cooperative laboratory involving NASA, the Alabama Space Science and Technology Alliance, and private industry.

If the formatting of this is messed up, or if the charts and graphs don't show up, then please click on the link to read it at the NASA website. I copied and pasted the HTML source, but it was messed up when I did the preview.

Hmm. From where I'm sitting, that looks messed up. I'm sorry. Please click on the link to see it correctly at the NASA website.

Gotta love real data over liberal feelings. Take that, envirowackos - let's see you refute REAL data.

Surface thermometer measurements indicate that the temperature of the Earth is warming, while the satellite data show long-term cooling trends.

"Question: How many fools, dupes, idiots and supposedly learned idiots does it take to understand that thermometers placed near/in cities will record slightly warmer temps?"

Answer: It looks like none of them.

"See!!! See!!! All these green house gas emissions due to Bush's failed environmental policies and the "Shock and Awe" bombing of Iraq has now caused enough Global Warming that we are headed for another ICE AGE!!!!!!"

Are you happy now RED-STATERS?" Bush's NEOCON policies will be responsible for the deaths of billions of poor minority women and children. If only you had voted for Kerry.

You drew an acurate picture of the liberal mode: reality in, garbage out.

Global cooling? Crap, I was rooting for the 'warming' tesm.

Well, those urbanizing stations aren't the worst of the problem. Liberals repeatedly use the intense warmth in Alaska to cry insidiously about global warming. Alaska is very mush warmer than it was in the 1960s, but that warmth has nothing to do with "global warming." The Pacific Decadal Oscillation flipped in 1977; the temperatures in Alaska from 1948-1977 show no real trend. The temperature trend since 1978 likewise shows no particular trend. But the average temperature jumped--in some places close to 10 F°--between 1977 and 1978.

Unfortunately, most Alaska stations do not have data that predates World War II, but paleoclimatic data suggest that we saw the exact opposite discontinuity in mean temperature sometime around 1946 and 1900 and the same discontinuity circa 1922. Well, not exactly; for some reason that we don't fully understand, the Pacific Decadal Oscillation appeared significantly damped during the nineteenth century.

When will the 9th circuit be asked by the ACLU to overturn the 2nd law of thermodynamics?

[R. Scott]

25 years is a “long term” trend?
However, it does give lie to the claims by environuts that the Earth has been warming at a dangerous rate the last few years.

Well posted Grundle.

Let me know if you wish to be added or removed from this list.
I don't get offended if you want to be removed.

They are a little more sophisticated now - the response will be more like this: environmentalist professor: The data indicates that the cooling trend is much slower than expected on our models, probably caused by greenhouse gasses from the USA, Japan, and to a small extent western Europe, but definitiely not from China. Capitalist Global Warming is causing Earth to experience slower Global Cooling than it should.
