I was reading an article in one of the paleontology mags about the copper mines in Chile, Chuquicamata to be exact, and they have a small team of researchers come into areas they opening in the pit mine to look for fossils. They only have a month to to look in these areas. This last year they found at a depth of 2800 ft, fossils of animals and reptiles that were huge, not just dinosaur huge, big enough that a Tyrannosaurus Rex wouldn't even be a snack. One of the snakes was large enough to drive a bus in and still have enough room left over for the passengers to get out. Per their research, the earth at that time had to have had an average temperature over 100F/38C for these critters to have grown so large. They also said the average humidity would have been close to 100%. WE get the heat here but it's not that humid and it's unbearable. I can't imagine humans living in that environment. Regardless of the earth's changing temp, we need to make the attempt to clean up the air as best we can. It's already possible to have a zero emissions engine that burns fossil fuels but due to politics, you can't have it. If a politician says it's an issue, know that there's money involved and he wants that money in HIS pocket.
If you live in Maine and want to see your local climate change, not just ecosystem get a few dozen red necks with chain saws and cut down a 20,000 thousand acres of forest. Watch what happens to the localized newly created treeless land in the summer and winter. Hint it will be hotter it will be drier and not so nice around towns with lots of cars. In the winter it will be colder but shorter with less snow and snow melt in the spring with high runoff. Makes drought. Yes man changes climate only a moron doesn't get this.
Any lessor animal or natural event can rapidly change localized or regional climate and ecosystem. With the smartest over populated animal on the globe, worldwide change is expected not debatable.
