There have always been shorter cycles riding on longer ones. It's the long term ones we have to worry about. There is no doubt, except by those who refuse to accept the evidence, that adding certain gases, such as methane and carbon dioxide to the atmoshere raises the temperature. There is a lot of evidence in sediment and ice core samples that show this, and it has happened naturally in the past. But since humans started burning coal, we've been adding CO2 to the atmosphere that had been locked away for millions of years. So, if you look at the earth's temperature over the past few hundred years, you will see many ups and downs, but the long term trend is up and at a faster rate than generally happens normally, other than when there's a significant disruption, such as a large volcano. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
