I agree, but you have to be careful about where you start. We've been cooling if you start when the earth was a molten volcanic miasma, but have warmed up considerably from the time the world was a giant iceball.
Yeah, we've known for a while that the Earth goes through climate shifts. However this particular climate shift is warming much, much faster than previous ones. We know this from the arctic ice drilling and probably other techniques I don't understand
It's pretty obvious that greenhouse gases trap heat... so would it not make sense to say that pumping more greenhouse gases into the atmosphere would equal higher temperatures? Seems like common sense
It's also important to note that even a change in the average temperature by one or two degrees may seem insignificant, but it can wreak havoc on ecosystems. We're already seeing its affect on polar bears in the far north. With all of the melting ice they're unable to hitch rides on floating pieces of ice, and as a result many of them are drowning from it.
