Wolverine to Vanish From U.S. Due to Warming?

The wolverine may have finally met an enemy it can't claw past: The fierce creature is at risk of being KO'd by climate change, a new study says.

Built for the cold, wolverines make their homes mostly in the northern forests and tundras of North America, Europe, and Asia. The carnivores are rarely found in places where temperatures get higher than 72 degrees F (22 degrees C).
During winter, the animals' thick, oily fur serves as insulation, while large, padded paws help them run across deep snow. In the spring, wolverines build dens in the lingering snowpack to shelter newborns.

Currently about 15,000 or more wolverines are believed to roam Canada, and an unknown number reside in Alaska. Only a few dozen to a few hundred are believed to live in the contiguous United States, almost all of them in the mountains of Wyoming, Idaho, Montana, and Washington State.

Is severe winter weather related to global warming?

You may not remember exactly what you were doing one year ago, but odds are good you spent part of the day shoveling, buying an extra pair of gloves or replenishing your emergency stash of batteries. Odds are even better that you remember what happened just before and just after the anniversary we celebrate today. The first of a pair of major blizzards struck Washington on Feb. 5 and 6. The reprise landed on Feb. 9 and 10.

Our region experienced record snowfall last winter, topping the charts dating at least as far back as the late 1800s. In all, more than six feet of snow fell at sites such as Baltimore-Washington International Marshall Airport. Extreme weather nailed other U.S. cities last winter, too, and swaths of Europe saw unprecedented snowfalls and record cold temperatures. This year, the nation's capital has suffered one unusually severe storm. Parts of the East Coast from Atlanta to Boston have been experiencing blizzard conditions. Last week, a vast swath of the country's midsection and East Coast got deluged with sleet and snow, paralyzing travel. What gives?
