"Secretary Hagel promised in his November 22 announcement that the US military would also work to “preserve the Arctic environment.”
That goal will be impossible to achieve if temperatures keep rising, say scientists.
The physical momentum of global warming—rooted in the fact that carbon dioxide [CO2] lingers in the atmosphere for many years after being emitted—insures that Arctic and global temperatures will rise for decades to come, even if humanity reduces annual emissions of greenhouse gases.
Thus scientists regard further melting of the Arctic as inevitable.
The only disputes are over how much and how fast.
“We are going to get into a ghastly situation for the planet at some point and whether it is happening next year or it is going to take a few decades is the only question,”
Wadhams testified to Parliament in 2012.
Although Wadhams stands alone in projecting an ice-free Arctic as soon as 2015, other scientists agree that the day is coming fast"
