Climate Change Predictions Overestimate

 The United Nations Intergovernmental Panel on Climate Change and a host of other respected organizations have made predictions on the increase in global temperature, all of which have been grossly overestimated. Current temperatures have all but fallen short of the predictions, which were collected via NASA satellites and compared to real-world temperatures in the 1970s. Said models were produced by "international government agencies, universities, and other climate groups, including 19 models produced by U.S. agencies, universities, and climate groups." Of these 73 models, all have predicted more global warming than has actually occured: With the 73 models averaged, 3 times more. 

The data was provided by John Christy, a professor of atmospheric science at the university of Alabama Huntsville. While this seems like completely positive news, Christy also points out a possible discrepancy between air temperature and "hot spots" in the troposphere, which skews data collected and modeling attempts, which can show an increase or decrease in climate when there isn't really one. This could be improved by, of course, more developed technology or a new modeling process, but modeling climate change is still difficult to do, with the number of factors involved as well as a lack of foresight about whether or not the climate is actually rising, or merely fluctuating on a scale larger than we know. For the time being, however, we can be a little more at peace that this data shows our worst fears about global warming are not coming true. 

I feel that these models provide insight into how we view global warming and a generally changing climate. While the possibility of increasing temperatures should never be ruled out, we should remember to look at the facts and not made apocalyptic predictions before observing long-term patterns and obscure factors.
