Glaciers Melting Unstoppable for a Long Time

That’s the conclusion of a new study reported by ThinkProgress:

The observations show that “the rates of early 21st-century [glacial] mass loss are without precedent on a global scale, at least for the time period observed and probably also for recorded history,” according to the study from the World Glacier Monitoring Service, based in Zurich.

[…]

The melting is speeding up. Glaciers are now losing mass twice as fast as they were in the period from 1901-1950, three times as fast as in the period from 1851-1900, and four times as fast as in the period from 1800-1850, the researchers found.

And the glaciers will continue to recede, even if global temperatures stabilize, the study’s lead author, Michael Zemp, told Climate News Network. “Due to the strong ice loss over the past few decades, many glaciers are too big under current climatic conditions. They simply have not had enough time to react to the climatic changes of the past,” he said.

In other words, the Earth’s glaciers are melting to keep up with temperature changes that have already occurred.

[…]

“It takes time for the warming to whittle down the ice sheets,” he said. “But it doesn’t take forever. There is evidence that we are likely seeing that transformation begin to take place now.” Carlson told ThinkProgress that “we are nearing one degree Celsius warming,” and that the “worst case scenario is what we are already on.”

Are we doomed because of the inability of our political class to say “Enough is enough” to the powerful Dirty Energy industries?
