I have yet to see anybody make a verifiable prediction with regard to climate change on anything less than what will happen decades from now.
1. There will be less glaciated area, worldwide, next year than there was last year. There will be less glaciated area, worldwide, in 5 years time than there is now.
2. The arctic ice sheets will contain less ice next year than they did last year, measured across the year. The arctic ice sheets will contain less ice in 5 years time than they do this year, measured across the year.
...and the time scale of all predictions concerns what will happen at mid or end of century, it's entirely possible that scientists are making claims that can't be falsified in their lifetimes.
Simply put, some people can see further than the end of their nose! (I apologise, implying you are shortsighted is not likely to help.)
Imagine a large pot, full of water, let's say a gallon. Now, put that pot on a stove. Does all the water in that pot, in your mind, immediately become hot, or boil? No? Why not? Is it going to get hotter? How long does it take? Is the end result in doubt? How much bigger than that pot is the Earth? Is the end result in doubt?
I'm 99% sure your answer to the last question will differ to your answer to the identical question that preceded it. To be fair so does mine, but only as a matter of degree. Or to rephrase that, the only doubt in my mind is the exact number of degrees, and that is inherently unpredictable, due to the action or inaction of others.
I choose to believe that the scientists don't haven't it all figured out.
You may chose to believe what you want, and I'll defend your right to do so. It is your actions, and the actions of everyone else (and that includes business as usual inaction) that I take issue with. The problem with beliefs is that they seem remarkably resistant to logic. And it is logic that is the basis for science, not what we wish were true, not what we believe!
