Global Warming Implies Warming and Cooling in the Same Place

Global warming alarmists have been focusing media attention for several years on some warming of the Antarctic peninsula and the ice shelves around it. This penisula juts northward toward the southern tip of South America, so it is strongly influenced by the local ocean currents. It represents a much smaller fraction of the land mass of Antarctica than the East Antarctica area where the ice mass has been increasing for many years. Computer modelers who claimed the earth was warming rapidly due to anthropogenic CO2 emissions were convinced that a cooling trend in the bulk of Antarctica was consistent with man-made global warming.

Patrick Michaels just wrote an article called Climate Scientists Blow Hot and Cold pointing out that a recent study of the temperature record in Antarctica by Eric Steig of the University of Washington used satellite observations to provide a means to track temperatures across wider areas of Antarctica than ever before. Most thermometer recording sites were on the coasts and very few were in the interior of the huge continent. The result is that relative to the temperatures of the 1950s and 1960s, there has been a slight warming of Antarctica as a whole, though almost all of it occurred in the early part of the time-frame from then to now. This indicates an earlier warming effect than has been claimed elsewhere for the man-made global warming by CO2 emissions proponents, which is puzzling.

Computer modelers have been delighted, however. Even though they claimed that a non-warming or a slightly cooling Antarctica was consistent with their global warming models, they are happier with a slight warming and are now claiming that that is consistent with their models.

Apparently all observed results are consistent with their models. If it warms for the next 10 years in Siberia, that is consistent. If it cools for the next 10 years in Siberia, that is consistent. If the higher altitude atmosphere warms, that is consistent. This is indeed a prediction that it should be warmer than the earth surface temperatures. But in fact, there has been no warming of these higher altitude air temperatures, let alone to higher temperatures than the earth's surface. But this gives the CO2 emissions global warmers no pause. It appears that there is no observation which will give them pause.

No matter what, man-made CO2 emissions are going to cause a disaster sometime in the future. So, stop exhaling now, so you will be morally pure and not responsible for this catastrophe! Then, there will be no need to force you to stop using coal or natural gas generated electricity or heating your home or business with gas, oil, or coal, using products manufactured with fossil fuel energy, or moving about in cars and trucks and planes.

Global warming has long been an issue worldwide. But concrete solutions were not yet made. And as cited above, air pollutants contributes much to this which needs to be reduced and minimized.

Rob,

Air pollutants can either cause warming or cooling to some degree, but the long industrialized countries have generally decided that there are enough health problems and environmental problems associated with the real pollutants, that they have been very effectively controlled. Some problems exist in some large cities and perhaps locally around some animal stockyards and some chemical plants, but mostly the problem has been dealt with to the point of vanishing returns.

The issue of CO2 is entirely different. It is not a pollutant. Every human and evey animal must emit it to live and it makes our plants grow better, since they must use it to grow and live. Calling CO2 a pollutant is an entirely different game, which is clearly meant only to hurt humanity in the pretense of protecting the God of Mother Nature. Of course, Mother Nature actually has nothing against CO2. She values it highly.
