There you go again turning the warming into a negative. The fact is that minerals and potential huge wealth will be available if reduced sea ice in the Arctic allows exploration. The American navy is there and so is the Canadian navy as well as the Russians and five other nations as we all have territory in the Arctic and have to defend it to keep it.
There you go again turning the warming into a positive. Why is it so hard to understand that these issues have multiple effects, positive
and negative. It's the balance that counts!
And the balance
is negative, it will cost our generation, but especially future generations, dearly. And not just in money but also in health.
To give you an idea, in my home town, the people on one side of town on average live 6 months shorter than those on the other side, due to pollution (particulate matter). And that's a finding that surfaced through epidemiological research. The PM sources are 70-80% anthropogenic versus 20-30% from natural sources like e.g. sea salt (we predominantly have wind directions coming from the sea) and pollen and decaying biomatter. And it's not just that these people will keel over faster, but they will suffer from all sorts of diseases like Cardiovascular issues and failure of organs like kidneys. So they will already become less productive and less healthy earlier in life, and will need more medical intervention (and thus face higher costs if they can pay for them).
What will happen in the Arctic is, territorial conflicts, drilling for oil, oil-spills that kill ocean life, and more burning of fossil fuel to accelerate the global warming even more (after it was already boosted again by the Albedo reduction from the loss of ice).
Being prepared, or better yet reducing/preventing such things from spiraling out of control, makes a whole lot more sense than closing one's eyes and hoping it will go away (spoiler alert: it won't go away). And prevention is a lot cheaper in the end as well, so it also makes more economic sense.
