Author Rebecca Solnit’s article this week in The Nation says 2013 is the “Year Zero in the battle over climate change, one in which we are going to have to win big, or loser bigger.”

The Earth we evolved to inhabit is turning into something more turbulent and unreliable at a pace too fast for most living things to adapt to. This means we are losing crucial aspects of our most irreplaceable, sublime gift, and some of us are suffering the loss now—from sea snails whose shells are dissolving in acidified oceans to Hurricane Sandy survivors facing black mold and bad bureaucracy to horses starving nationwide because a devastating drought has pushed the cost of hay so high to Bolivian farmers failing because the glaciers that watered their valleys have largely melted.

She notes that an Associated Press poll this month found that four out of five Americans say climate change will be a serious problem if nothing is done. Americans are starting to recognize that it’s not only an environmental issue, but also an economic one.
