I'm not disagreeing, but sadly I feel it may take catastrophic events to get everyone to stop bickering about politics, brexit, reality tv, and all the other trivialities people like to spend their time arguing about.

Logically, to me, if we know what has caused cooling in the past ( whether it's an abundance of some algae, low carbon, or blotting out the sun with ash, I've read all three), we have an idea of what we could try.
