Those peaks and troughs are happening over the course of thousands of years. For example: those melting rates are measured in millions of years. Earths climate temp is rising incredibly fast over a shot period of time; much quicker then historically expected.
You do realize our atmosphere was prominently carbon rich during those warmer year?
What are the factors causing Earths temperature to rise and fall over these large periods of time? Volcanic activity, orbital periods, sun temperature, or greenhouse gases?
It seems like you're friend is misinterpreting data for his own benefit or is lacking any knowledge of historical climatology. He is however correct about over speculation by certain climatologists; the debate currently isn't over IF but HOW MUCH.
> P, therefore Q> Q, therefore PJust like historical climate data has no relationship with the greenhouse gas effect :^)
The greenhouse gas effect is real, here I found a page for your level of education:
http://climatekids.nasa.gov/greenhouse-effect/>>8348680Venus's atmosphere is made up of 97% CO2 (resulting in much higher surface pressure than Earths) . I'll remind you that the gas giants are also opaque, by your logic they should be incredibly warm as well.
