I agree with #1 totally. I mean even the 3 brilliant and knowledgeable skeptical folks
@MichaelJ mentioned that support his own middle of the road position that even he said is similar to mine, have clearly stated they believe AGW exists. One of them, the brilliant Dr. Roy Spencer said:,"
I routinely take other skeptics to task for believing such things as 'there is no greenhouse effect',"
and
"I believe the climate system has warmed (we produce one of the global datasets that shows just that, which is widely used in the climate community), and that CO2 emissions from fossil fuel burning contributes to that warming"
Spencer, Curry, and Christy are skeptics not because they don't believe in AGW but because they don't believe in the alarmist catastrophic scenarios often shown by models and also spouted by leftists for political purposes. Look above for all the quotes I posted from all three of them.
In other words, these three believe that John Coleman is full of BS, but that also the leftist Democrats are full of BS.
You then said:
"2) We cant pinpoint the exact amount of impact manmade GHG's are having but its not none and it grows more significant every day.."
Regarding your #2, I agree with the first part 100% as nobody knows the exact amount of impact.
Regarding the 2nd part, I have several things to say: it does appear it is growing more significant every day but
I also feel that at some point negative feedback of some kind (possibly unknown) may come in and halt the warming well before climate models say so. It could even happen soon for all I know. Or perhaps some totally different climo factor enters the picture and causes enough cooling to counter the AGW.
Also, I feel that you should have included what JC mentioned: that increased food production and increased greening of our planet are likely positive effects of AGW. By the way, increased greening may itself eventually impart enough negative feedback to halt GW. Also, fewer people freezing to death, lower heating costs, etc.
It is conceivable that AGW is a net positive for our planet. I don't know that, but it is something the left will never even mention for obvious reasons. I'm saying this even as one not far from the coast who is concerned about future sea level rises affecting Tybee Island, etc.
