As I said, I know nothing about the IPCC, but the fact that they falsified data doesn't change the fact that in the last few decades, the climate, not only temperature, changed brutally. We should also keep in consideration the timespan in which events happen, not only the absolute values, because time is necessary to adapt. It's clear that "industrialization" moved some values suddenly, and humans have not been able to keep pace with evolution to avoid serious damage.

Btw, what IPCC's final goal?
