Unusually high air temperatures and a warm ocean have led to a record low Arctic sea ice extent for November, according to scientists at the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder. In the Southern Hemisphere, Antarctic sea ice extent also hit a record low for the month, caused by moderately warm temperatures and a rapid shift in circumpolar winds.
Sea Ice Hit Record Lows in November
On October 1, top chemistry researchers from around the country came to Missoula, Montana, to light stuff on fire. They converged at an old building that looked like a mad scientist’s warehouse. Inside, they helped each other set up millions of dollars worth of instruments. Wind tunnels weaved in and out of the walls, and a rickety elevator ferried researchers to the top of a giant smoke funnel. These scientists were kicking off a multi-year mission called FIREX—Fire Influence on Regional and Global Environments Experiment, to better understand the air quality and climate effects of fire—in the controlled environment of the Forest Service’s Rocky Mountain Research Station Fire Sciences Laboratory (Fire Lab).
