hmm...so...whats the Null hypothesis to Anthropocentric Global Warming? That weather events stay the same as in the past? That there is no change? that weather remains constant and the climate holds within 0.1 of a degree globally averaged for 100 years?

If any of these things ever did happen, it would be highly unusual! Climate changes, always did, always will.

(I won't bring up the burgess shale if you don't try the "rate of change argument!")

I just wish we had the Prehistoric atmosphere of a constant 30C degrees at the equator and a constant 10C degrees at the poles with a hazy sky and 3 times the amount of oxygen which allowed giant lizards to hold their immense weight up and glide high in the sky.

Ahhh. Them were the days indeed.

Of course climate changes, our ice ages are proof of this. Indeed it was through trying to understand these past changes that climate scientists worked out the critical role CO2 plays in these climate shifts. A slight temperature increase caused by an orbital forcing increases atmospheric CO2 which precipitates further temperature increases. It is why atmospheric CO2 generally lags temperature. There is no logic whatsoever to the argument that because climate changed in the past anthropogenic increases in atmospheric CO2 are not forcing current changes.

Absolutely agree Motr.  I find that the deniers consider that humans are either;
- too unimportant to have such effects, or
- somehow are divorced from the earth,above it, like we don't REALLY live here, and therefore we can do anything we like, without consequences.!!.

Its like some holy belief.!!! I shake my head in amazement at the Folly.!!

I don't doubt it at all.

Some folk just deny it all together....... it really comes across as the basest stupidity.

It is as if we are exempt !! 'cos we believe in GOD.   ( not me tho) ,  or the same old same old..... its happened before..ie it's not our fault. we are innocent.!!  (whine whine)

Its like these monster tornadoes wiping out much of the US heartlands.!! 
The reporters refer to the 'wrath of mother nature'.!  But they don't seem to wonder why?

I'm not the one who been programmed, nor am I gullible.
Now, don't be late again to sing hymns in the Church of Global Warming today.
Their counting on you.

neither is there any logic in assuming that current warming MUST be the result of human co2 emissions!

Models are models, I generate computer models in my work too, however I do this to find an appoximate answer, I don't start with the answer then adjust the model until it reflects what I believe to be true.
