You offer yet another observation without a link, without substantiation. "How much of this is due to human activity" is, indeed, unknown. You can't ask for a link to prove a negative. If it's known, then it's up to you to come up with the link. none argue there is none. Indeed, no rational and informed person argues that there is none. But how much more than none is, well, unknown. Simply no debate on that point. There's plenty of debate. At least there would be if half the folks weren't trying to scare us to death and the other half beating up on the first half. Then somebody might be able to find time to determine how much of it is human generated. Yet another unsubstantiated, unlinked observation. You and I have discussed it before and you apparently haven't been slowed down a bit by that discussion. Remember? We're still missing a plan. absolutely no one in the circle of those who care enough about the issue to devote their life work to it (the scientists for one ), argues nothing can be done. Once again, no rational person argues that absolutely nothing can be done. Surely we could at least slow it down a bit. But that doesn't mean that we can stop global warming no matter what we do. You offer yet another observation without a link, without substantiation. And you're not?

Google gives 130,000 hits for {"mass balance" Greenland}. Look at a few and you will see that the results are quite varied. Here is one: eurekalert.org I am sure that you can find lots of writing about global warming with scary titles. Predictions of catastrophe never seem to work out. Remember the "Club of Rome"? Remember Paul Ehrlich? Couldn't have been more wrong. Who knows, maybe the doomsayers will be right this time. The surface and satellite records agree fairly well on the 0.2 deg/decade warming. Google it if you wish. As Lane3 has answered your other points I'll leave it at that.
