Global warming hardly a left-wing conspiracy

I got a big laugh out of Thomas Crosswhite’s letter claiming warming seas and melting polar ice caps cannot cause mean sea level rises and it’s all a big made-up sinister left-wing conspiracy.

Thomas must be getting his science from the world renown climate expert Rush Limbaugh. Thomas needs to go back and take a few high school science classes. His logic is so convoluted and incorrect that I haven’t space to answer its fallacies but I will address two.

First, water expands as it warms and takes up more volume; the oceans are warming. Second, the net amount of land ice from both poles combined is shrinking.



Sea levels rose eight inches between 1870-2004 and are projected to rise an additional 7 to 21 inches in the next 90 years, but that may be accelerating.

Storm surges can greatly multiply the damaging effect in coastal areas of a two-foot rise.




Even if you are a big oil climate-change denier and do not believe climate is changing due to anthropogenic causes, the seas are rising and acidifying with potential disastrous results for 70 percent of the world’s population.
