What would a +2°C warmer world look like?

So, the world has already seen conditions with high CO2 and temps 2-degrees centigrade today — and life flourished. Darn those inconvenient truths.

Watts Up With That?

Cretaceous_Trail_sign,_South_Table_Mountain[1]An argument regularly advanced by alarmists is – can we afford to take the chance? This argument is often associated with a claim that a rise in global temperature greater than 2°C would be catastrophic – a theory backed by authoritative sounding computer simulations which suggest dangerous ocean acidification, deadly heat, and extreme weather.

It is all very well to simulate these scary possibilities, but at the end of the day a computer simulation is just an educated guess – it is no substitute for observation.

Wouldn’t it be great if there was a way to actually observe what a warmer world would actually be like? What if it were possible to create a parallel Earth, dial up the CO2 level, and actually see what really happens? Would anyone bother running a computer simulation, if we could observe the reality?

We can’t create a new planet, but there is a…
