lolololol, right. too funny. records are made to be broken esp since we only have a track record of 150 years or so on a planet 5 billion years old. but it's man made lololollolol

Hi combjelly; Re: "As I keep pointing out, weather is a chaotic system . When a chaotic system shifts from one strange attractor to another, like with climate change, the system swings between extremes."; To a large extent this is true, but the two extremes the earth's climate can reach are "glacial" and "interglacial". During a "glacial", the US and Canada can produce almost no grain due to a combination of glaciers and reduced moisture. The tropics also get a lot less moisture (mostly) and some of the rain forests revert to grassland. This would be a disaster for humans. Right now we're in an "interglacial". These are good times for humans. At the moment our temperatures are low for an interglacial. For example, the ice cores from Greenland, which give the longest accurate approximation of temperatures, show that it was 8 degrees C warmer there over 125,000 years ago (during the previous interglacial which is known as the Eemian). Around this range, a little warming (such as we can get from CO2) is good for humans. With a little luck we'll find enough carbon fuels to postpone the next glacial long enough that we can figure out how to engineer it away from happening. Oh by the way, those northern forests you lefties are so intent on preserving are only about 10,000 years old. 90% of the time the land they're on is either too dry for trees or covered with ice. If mankind doesn't alter the planet's climate, those forests are doomed; they'll be destroyed by the next ice age just like they've been destroyed dozens of times in the past. -- Carl P.S.
