For James Overland, an Arctic oceanographer at NOAA’s Pacific Marine Environmental Laboratory, six exceptionally slushy summers in a row in the Arctic demanded an explanation that went beyond the obvious: that global warming is raising the Arctic’s temperature. After analyzing winds and pressure patterns, Overland and several colleagues documented an unusual shift in the prevailing June winds—from westerlies to southerly—that amplified Arctic warming and sea ice melt.

With the end of the most active part of the Atlantic hurricane season approaching, there is still plenty of water in the western Atlantic basin that is warm enough to fuel hurricanes.

September 2012 tied with September 2005 as the warmest September worldwide since record keeping began in 1880. See which countries saw warmer-than-average temperatures during last month, and learn how weak El Niño conditions might progress into the Northern Hemisphere winter.

Arctic sea ice extent set a new record low at the end of the summer melt season on September 16, 2012. But extent is not the only quality of the ice that is changing. Wind and ocean circulation patterns are conspiring with a warmer climate to reduce the amount of year-round (multi-year) ice, transforming the remaining ice into a younger, thinner version of its old self.

According to the latest statistics from NOAA’s National Climatic Data Center, September 2012 marked the sixteenth consecutive month with above average temperatures for the Lower 48. Meanwhile, warm and dry conditions persisting in the Northwest have led to yet another month with above-average wildfire activity in the region.
