Since I've posted anything on the environment, so now seems like a good time.
Three pieces of interesting and alarming news in the past week:
Scientists studying ice cores in Antartica have found that there is more Carbon Dioxide in the atmosphere than at any time in the last 650,000 years. "The levels of carbon dioxide have climbed from 280 parts per million two centuries ago to 380 p.p.m. today." That is a 36% rise in just 200 years.
