If CO2 levels have increased the amount of radiated heat that is being trapped within our atmosphere, we should not be setting record lows. But we are.
Also, warmer ocean water leads to more evaporation and more rain. It rains much more in the tropics then is does up in the higher latitudes. That is why the extensive rain forests tend to located nearer the equator, which receives more sun energy and is hotter.
Exactly. All their protestations of calamity miss this salient point. They perceive an increase in temperature only, without considering the resultant increase in evaporation.
Desertification grows during an ice age. Deserts shrink in a warming global climate.
Instead of species dying off, almost all will see a growth opportunity in a milder climate. Consider the rich fauna and biota of Florida as opposed to northern Minnesota or North Dakota.
The African continent has had special problems climatically, and it always will. We as a species should have moved out of there long ago.
