Going against my own advice, here:
This was the most basic "study" I could think to give you, and this data is undeniable FACT...if you think otherwise, you are simply delusional. Never before in geologic history has average temperature changed so rapidly, aside from catastrophic events such as the asteroid impact that caused the K-T extinction.
Furthermore, it occurs to me that since this data IS fact, the burden of proof is actually on your end to show that man is NOT causing climate change, since there is clearly a correlation between increasing man-made CO2 emissions and increasing temperature. No data exists to provide that evidence, but good luck anyway.
You can continue to ignore the obvious connection if you want, but you're just lying to yourself for no good reason.
