The calculus of unsustainability
.
Sustainability is a squishy term—and difficult to operationalize for public policy
.
Perhaps the underlying problem is the public’s lack of understanding about material stocks and flows, integrals and derivatives, i.e., the calculus of unsustainability. In the U.S., we simply do not seem to get it.

@eagle1O9 That scenario would be if Earth's climate wasn't being altered by extremely high emissions of CO2 caused by humans. But, the opposite of your scenario is bound to happen if immediate action is not taken.

@failurbanik Summer Arctic sea ice is expected to be GONE in 5-20 years. Average temp. rise estimates for this century are +1C - 5C (MIT estimates =+3.5 -7.4C).
It depends on how much climate feedback mechanisms, like ocean warming & methane release kick in.
Different models predict different scenarios. No one actually knows.
