Mark....I do not deny man-made global warming as you know. However it is a fallacy that this agreement , structured around a non-binding, non-enforceable model with large transference of funds, catch-up periods and governmental affinity for tax-based approaches to mitigation, , in a world which isn't aligned to trust or co-operate on far smaller issues, would have ever acted to meet its targets.

If the world is facing an existential threat Mark then the world needs to start acting like it's facing an existential threat...one brought on by a general lack of cheaper-than-fossils technological alternatives to fossils...not using global warming as a means to drive all manner of governmental and UN  initiatives under the guise of combating climate change
