You know my reasons. Do I need to repost them again? I find certain arguments that take wider perspective to be more compelling than others.
Considering that I am pro-environment, don't you think that it is strange that I don't believe in AGW? Because their arguments are flawed, I don't accept their conclusion.
Why I doubt AGW:
1) Cherry pick the data.
Compare current temperature rise with unusually and rare cold point in earth's history.
2) CO2 lags behind temperature changes by 400-1200 years.
So much for CO2 causing or amplifying warming.
3) During late Ordovician period it was as cold as today, yet CO2 was above 3000ppm (vs 396.80ppm today
). So much for current catastrophic levels of CO2. Solar activity is said to be lower during that Ordovician period, so solar activity was a factor. CO2 didn't play its alleged role and couldn't, see my point #2.
If it comes to solar activity being a factor of warming or cooling, then humans can't be blamed for warming.
4) During 70's there was a scare of global cooling. I wonder why... Because Earth was not warming up. And during recent times, past decade, the temperature rise appeared to have stalled. http://www.theregister.co.uk/2013/01/16 ... e_figures/
5) The average Earth's temperature within past 600 million years never seems to never go higher than ~24C (today it is 14.51C
) even if CO2 goes from 4,400 to 7,000 or stays at 3,000ppm. What is the mechanism behind holding temperature no higher than 24? Why can't this mechanism work today or in near future?
6) Is there even long term causal correlation between CO2 levels and temperature?
During first half of Cambrian, CO2 rose
from 4,400 to 7,000ppm yet average global temperature remained steady at ~23C.
During 2nd half of Cambrian, CO2 fell
from 7,000ppm to ~4,400ppm yet average global temperature remained steady at ~23C.
During Siluriun, CO2 fell from ~4,400 to 3,000 yet average global temperature was flat at ~23C.
During Cretaceous as CO2 was falling
from 2,000 to ~900, yet temperature increased
and then stayed at ~21C.
Obviously there is something much more than CO2 that drives temperature which doesn't seem to go above ~24C average. So no worry about Earth becoming too hot for life. There seems to be mechanism (in the past 600 million years) that doesn't allow temperature to go above ~24C.
