No, to reason and fact. I don't believe others here because they sound authoritative, but because I've come to similar conclusions by reading the actual research.
Climate science is not predicting doomsday, although if you are informed by 2nd or 3rd hand accounts, you may get this impression (or, indeed, the opposite, depending on where you get your information). The science is complex and boring, and the predictions have uncertainty and nuance.
I understand your skepicism, because there have been all sorts of "scare stories" over the years. The format tends to go something like:
Scientist: "I've observed certain behaviours in the atmosphere due to particulates from smoke and volcanoes, which are reflecting heat back into space. If my assumptions are correct, this could lead to an overall cooling effect over the coming decades and centuries"
Press: "SCIENTISTS PREDICT SNOWBALL EARTH"
The science that led to the "global cooling" prediction was not bad science. Increased levels of particulates *do* have a cooling effect on the climate. However, it did not take long for climate science to progress past that conclusion. As more and more data was gathered, and models became more and more comprehensive, the greenhouse effect was found to greatly outweigh the cooling effect.
There have been decades of research now, from all countries, using multiple methods. They all agree, and have had their models confirmed with the real data, that the warming is real and that we're causing it. The sea level is rising, the climate is changing, and unless we make *drastic* changes (rather than the more gradual ones we could have made if we started 30 years ago like we should), then those changes will continue on their present trends. The world is not going to end, but it is going to cause us plenty of problems.
