A study suggests climate change hastened the fall of Rome!

The rise and fall of civilizations are determined by climatic conditions.  For 2,500 years climate change impacted human history. 

Wet and warm summers prospered Rome while dry and varying conditions stymied the Western Roman Empire.

If we know historically that climate change caused the demise of civilizations will we take responsibility to mitigate the effects of current climate challenges?  Ask the dumb ass human ostriches who won't get onboard!
