A Thawing Arctic


The year that Arctic Row rowed across the Arctic Ocean we witnessed the lowest ice cap in recent history. And the trend predicts more melt to come.

The Arctic, the roughly 8 percent of the earth above latitude 66º 33′ north, is warming faster than many climate scientists expected—at nearly twice the rate of the rest of the planet. The extent of Arctic sea ice, which melts to its nadir each September, has steadily declined over the past three decades. The years 2007–2013 saw the six lowest levels since satellite imaging began in 1979. Overall, the ice cap has retreated about 40 percent over this period. The trend is likely unmatched in recent human history, reported a UN panel on climate change in 2013.
