Dealing with global warming as before is a recipe for disaster, as is pinning our national security on unstable suppliers. If global warming gets to the point of opening up new sea routes then atmospheric warming may well have started to release methane locked up in permafrost, a serious tipping point as CH4 has a global warming potential much higher than CO2. Sea level rise will also threaten low-lying populated areas more than it does now.We'll deal with the global warming issue as before, international conferences with resolutions but no firm agreed targets. After all, global warming is opening up those important northern waters, slashing navigation costs and accessing vast new oil reserves. This is a gift horse which will not be kicked in the mouth as witness the scramble to claim rights in that area by those powerful countries who want the ice to melt
A gift horse that enables us to access and burn even more oil in this scenario is a going to be more like a Trojan horse.
