You're a fucking ignorant mongoloid.
> Global warming is one of the results of climate change along with sea level rise, ice cap loss, extreme weather, etc.
That's literally backwards you pants pissing pansy. The earth is experiencing Global Warming, an increase in average temperature. This drives climate change, changes in local weather patterns that include increases AND decreases in local temperature.
> Yes, it has been warmer in the past
ooh fun fact.
> Unfortunately there wasn't 7 billion humans on the planet during the Mesolithic period
so the fuck what? go back to eating ass, at least you're better at that than you are at making an argument.
That the earth was warmer and without humans doesn't change the base fact that (seemingly) the earth could sustain life despite higher temperature equilibrium due to (presumably) higher radiative forcing.
> Climate models have been pretty decent actually.
No. Short run climate models are decent. Long run climate models are nearly indistinguishable from chance alone. Fact is we don't know very much about the long-run effects of climate increase, with a variety of consequences of warming implying a mitigating or exacerbating effect.
The core and insurmountable problem with the research on this front is the extent to which the academe has been tainted ideologically in favor of (mis)representing the issue as a global catastrophe which demands collective government action to address.
The truth is that we have no reason to expect individual choice to live lower-energy lifestyles, nuclear energy, and future carbon (or rather, GHG) sequestration technologies to fail to mitigate the extent of climate change. A basic fact is that Wind Energy has been cheaper to build and operate than any carbon energy technology for what? half a decade.
Again, go suck the farts out of the nearest asshole.
