Here at COTTonLINE we have taken a skeptical view of human-caused global warming, and we still do. On the other hand, we remain open to scientific evidence that points in the warming direction.
That said, you might want to take a look at an article in Scientific American about rising rates of C02 in the atmosphere. It seems to lack "the sky is falling" tone of many such articles.
The article reports that C02 levels are rising, period. It suggests there may be a link between such increase and warmer climate. Whatever your view of the climate change issue, this article may interest you.
Who knows, the DrsC may find it attractive to winter over in Wyoming if they live long enough to see serious warming ... an unlikely possibility. Of course, then we'd need to install air conditioning as the summers would be warmer too.
