I have always stated that (almost) everything good came from the Palaeolithic era and that more palaeo-style emulation by humanity would be the answer to a lot of problems. It seems that scientists are finally agreeing with me!!!
I was never sure re climate-change notions but I do concede that human destruction of the environment has caused chaotic weather in recent decades. For example, my holidays in Northern Italy now involve far hotter summers with rain in non-summer months either not happening at all or occurring in sudden weeks-long flash-floods which wipe out terrain etc. My skiing has been similiarly hit with much poorer snow-conditions before and after January/February with far too much snow during those 2 months.
