Global Warming Data May Be Flawed

World may not be warming, say scientists

My comment: Heat islands and the placement of data gathering instruments in or near those environments are a huge factor in weather data. Here in Kansas City, the differences between the Downtown Airport and KCI in the temperature alone can be upwards of 8 to 10 degrees, especially on calm days. I check the weather at both stations every day and typically, during the winter, the difference averages around 4 degrees on days with light winds.

Kevin Trenberth, a lead author of the chapter of the IPCC report that deals with the observed temperature changes, said he accepted there were problems with the global thermometer record but these had been accounted for in the final report.

?It?s not just temperature rises that tell us the world is warming,? he said. ?We also have physical changes like the fact that sea levels have risen around five inches since 1972, the Arctic icecap has declined by 40% and snow cover in the northern hemisphere has declined.?

The European Centre for Medium-Range Weather Forecasts has recently issued a new set of global temperature readings covering the past 30 years, with thermometer readings augmented by satellite data.

Dr Vicky Pope, head of climate change advice at the Met Office, said: ?This new set of data confirms the trend towards rising global temperatures and suggest that, if anything, the world is warming even more quickly than we had thought.?
