Earth’s melting polar ice has been speaking to scientists and the message is terrifying
In the seven years since the release of An Inconvenient Truth , Box says that Earth’s melting polar ice has been speaking loudly and clearly to scientists—and the message is terrifying : “If we’ve learned anything, it’s that we’re under-predicting the sensitivity of the cryosphere,” he says. “The ice is telling us that abrupt climate change is well underway. You’ll hear people say we’re going into uncharted territory, but that’s not correct. We are already in uncharted territory.” Simply put, we’re melting the world’s ice-covered regions. And this extreme thaw is a problem for two big reasons. One, the excess water will cause sea levels to rise, thereby threatening countless coastal communities.

In 2012, the Arctic ice cap shrank to a record low, with only 24 percent of the Arctic Ocean covered by ice, a 50 percent drop from 1...
