Letter: The trend lines speak for themselves
Re: ‘Climate consensus’ (Metro, May 9-11)
Everybody has freedom of speech. But you do not have the freedom to harm me. Please, all skeptics, stop arguing temperature and take a minute to look at the graph of the concentration of CO2 in the Earth’s atmosphere, which you and I breathe. It’s been measured on a mountaintop in Hawaii and also in Antarctica. Readers can Google “carbon dioxide in air” or go to www.esrl.noaa.gov/gmd/ccgg/trends or any other website that has images. You will see for yourself that the level trend jiggles over the year but the curve is sharply upward!

Re: ‘Cool the debate on global warming’ (Metro, May 8)
The claim by letter writer Vlado Haluska that global warming could be natural is without merit. Virtually all scientists agree that warming is real, and most believe it is man-made. Natural cycles in the past occurred over geological times of thousands of years. Our warming was not detected 50 years ago, and has been rapid since then. The only event to cause it has been human activity.
