Annual Temperature Trends in Canada

The climate in every region of Canada has gotten warmer during the last six decades.

Winter Storms Have Grown More Devastating

Severe winter storms that leave behind million of dollars in damage have become less common in the United States over the last five decades. But at the same time, individual storms have become more massive and destructive.

Coldest, Hottest Places Depend on What's Measured

The town or city in the continental United States that can lay claim to being the hottest or coldest location hinges on how temperature is calculated.
