Arctic Warming Could Cost Upwards of $60 Trillion

The worldwide impacts of a rapidly warming Arctic could cost the global economy an estimated $60 trillion, nearly equal to the entire global economy in 2012, according to a new study, reports Andrew Freedman at Climate Central. That report, published recently in the journal Nature, is the first to analyze the potential economic costs of rapid Arctic warming. The study bluntly warns that the tendency for policymakers to focus solely on the benefits of an increasingly open Arctic Ocean — like increased mining, oil and gas drilling, and maritime shipping — misses the longer-term “economic time bomb.” The Arctic region, the study said, is “pivotal” to the functioning of the global climate system. Disrupting it will not come cheaply. The authors derive their huge cost from the damage arising from the  possible massive release of methane, a very potent, short-acting greenhouse gas, as vast frozen deposits melt from 2015 to 2025. The cost outweighs by far any possible economic advantages of an ice-free Arctic.  Furthermore, the study doesn’t even include the increase in global warming from the looming total loss of summer Arctic ice, a major heat shield for the planet.

Join the swelling numbers of voters TELLING Congress they’ll vote for Clean Energy candidates here: http://signon.org/sign/we-are-the-clean-99?source=c.em.cp&r_by=487176 . This is an ongoing campaign (the next Congressional election is in 2 years!) so please, spread the word. It’s our way of telling Congress that a strong clean energy voting bloc is out there. This is how YOU can make a difference.

Melting means the area is poised to deliver a giant gaseous belch at any moment  – one that could bring global warming forward 35 years and cost the equivalent of almost a year’s global GDP.
