Letter: Earth in flux
Re: ‘Long-term data tell different story on climate change’ (Metro, Feb. 21-23)
I would like to point out that our average temperature today is built upon daily temperature readings taken since 1865.
During any given period since that time, average temperatures will rise and fall. It’s averaging these numbers that allow us to arrive at the “norm.” Now, just because the winter of 2013 was a very warm doesn’t mean that temperatures will continue to rise just as because the winter of 2014 has been brutally cold doesn’t mean that temperatures will continue to fall. It simply means that temperatures fluctuate and that fluctuations are themselves the norm. Further, while I don’t necessarily disagree that temperatures are rising globally, I do disagree with it’s supposed cause and also with its supposed effects.For example:
Recently a ship in Antarctica studying global warming was trapped in the ice and had to be saved by ice-breaking ships. This, and the fact that the Arctic ice is growing, disproves scientific predictions from eight years ago that “in five years the polar ice caps will be gone.”
During the age of the dinosaurs, the mean temperature was much warmer than today and during the “Little Ice Age” (1550-1850) the mean temperature was much cooler.
During the former, humans weren’t even on the planet — and during the latter, humans were essentially pre-industrial and therefore could not affect global temperature.
