Fairbanks is the only community in the state with an historical record tracking the “green up” date. And this year, it was right on schedule.

March was exceptionally cold in Alaska. But in April, almost every part of the state was above normal.

The date and severity of river breakup in Alaska depends a lot on temperatures in April and May.

Methane hydrates are clumps of gas entrapped in a water lattice on the ocean floor. Some scientists think of these hydrates as a ‘time bomb’ for climate change.

Across the globe, the entire atmospheric circulation pattern is driven by temperature differences between the tropical latitudes and the Arctic.

For most of the state, the entire month of March has been clear and cold.
