| Global a/c - The warm Air/water currents do flow northward, cool down and then flow back toward the equator. Though global warming is happening, the greenhouse gas being the cause is only theory. As hip said the ice has melted before, the planet has gone through ice ages multiple times, and probably, following logic, has gone through Hot (no ice) Ages. The planet may be trying to cleanse itself...of some sort of.... Parasite? |
