Okay, I'll tell you my thoughts.
First, my look at it:
We are in a warming trend. It's not linear, but accelerating. And this corresponds to what has been constantly predicted for some 20 years.
Second, search for reason:
We are mankind, and we are able to stupid things to the environment. Our input into GW is only bound to warm. Just a question of how much.
Third, The consequences:
Well, it really doesn't take a long time of this to carry on to make quite some woopsies to mankind.
Fourth, What can we do:
Well, if we have a finger in this, we must look into that our own doings are also accelerating. There was a very good lecture on how numbers stack up somewhere above in the thread. So, what we can do, is mend our ways, so we won't be putting an increased weight on to GW. And this is partially why I belive that the most die-hard denialists of GW come from the USA....4% of mankind using 25% of the energy or something in that size, that's bad....
Fifth, Consequences II, what if GW is not a problem. MMGW a hoax, and all is honkey-dory?:
Well, we're going to screw ourselves in about the same time as GW would do to us, - resource-vise. There is no way our "line" is going to be able to carry on as it does....
