Quote from: dahangWe are now in uncharted territory involving CO2 emissions. Never before have the levels been this high (>400 ppm), and we are seeing an rate of change in temperature like never before.1 degree in 100 years, shouldn't the temperature have increased more from 1940-2000, or do you think the lack of increase was due to natural causes? the IPCC says the earth will be 8 degrees warmer in 2050, i'll be around to see this not happen.there are other reasons, besides CO2 emissions, why we might measure a higher rate of temperature change. you have the urban heat island effect, the chopping down of forests, inaccurate measurements, etc. if CO2 has a significant effect, satellites should be measuring higher temperatures as well. not that i believe the earth has never warmed this fast; who knows, how many ice core samples do we have? does one measure the earth's average temperature from one location? how do you show CO2 significantly increases temperature? what about factoring in other causes when we can't measure their effect? not to mention we don't know what to expect naturally. you keep showing me a graph of CO2 and temperature, isn't it obvious temperature would dictate CO2 levels. there are so many other factors that dictate temperature, and CO2 levels always seem to vary with the temperature. how are you determing CO2 alters temperature significantley? seems to me the professor of atomopheric science from MIT had the right attitude.

I"m not sure what this obsession with evidence is

1 degree in 100 years,
in my opinion there are to many unknowns
