I hesitate to prolong this discussion but, as someone who does worry about the way the planet's atmosphere is changing and, as a result, having an effect on our climate, I must point out that one particular comment made earlier is something I feel isn't accurate. I quote from Dr Emily Shuckburgh, a climate scientist working with the British Antarctic Survey.
"Today’s atmosphere is unprecedented throughout human history, prehistory and beyond. To find equivalent levels of CO2 you have to travel back in time more than three million years. Ancient air bubbles recovered from the Antarctic ice sheet tell us how CO2 levels have varied naturally in the past, demonstrating that the dramatic increase since the industrial revolution lies far outside the natural cycle."
