Tipping Point

This video does a good job explaining the concept of the tipping point and positive feedback loops. However I don't think it gives enough credit to the earth's capacity to rebalance itself. For instance, as ice melts in Greenland fresh water floods into the North Atlantic. This freshwater is likely to shut down the Gulf Stream leading to a cooling trend in Europe specifically. Forget about crops in Scandinavia then. But of course what do I know, this may not happen at all.

I personally don't think that climate change will lead us to Venus-like conditions since I have faith in our wonderful earth but we, humans, are most definitely fucked. But as long as there is microscopic life around volcanic vents under the ocean I will die moderately happy. Human civilization has definitely failed and is irredeemable, the only tragedy would be if we took the magic of life on earth with us.
