The world at the last glacial maximum. Deserts were much bigger than today, and tropical forests were substituted by savanna due to delayed and reduced monsoon rains. Over 70% decrease on rainfall over Africa, and death of 50% of temperate trees species in Europe. Winters lasted far longer, and temperature lines on February, for instance, were around 20K lower than today. Almost impossible for man to live in latitudes over 35 because of harsh and unpredictable climate conditions.
Ah, the holocene climatic optimum. Temperatures were higher and the world was far moister, despite ice caps lingering over what is the Hudson bay nowadays. Florests expanded and no Sahara desert. No summer ice in the arctic.
Talk about which one is dangerous now - cooling or warming. Of course things are different nowadays, due to changes being much faster meaning continents will warm before the oceans, but in the long term things should estabilize if emitions were controller. Instead of this, people insist to engage in an almost irrational doomsday-like movement against global warming.
