Researchers in Massachusetts and Wisconsin are comparing modern flower blooming data with notes made by Henry David Thoreau and Aldo Leopold. The sight of irises blooming during a Boston winter helped spur the research.
Modern scientists trying to understand climate change are engaged in an unlikely collaboration — with two beloved but long-dead nature writers: Henry David Thoreau and Aldo Leopold.
The authors of Walden and A Sand County Almanac and last spring's bizarrely warm weather have helped today's scientists understand that the first flowers of spring can continue to bloom earlier, as temperatures rise to unprecedented levels.
The federal government hit its debt limit at the end of last year. Since then, the Treasury Department has been taking what it calls "extraordinary measures" to keep the government funded and avoid defaulting on U.S. obligations.
But those measures will run out sometime between the middle of February and early March. Then it's up to Congress to raise the debt limit.
House Republicans are wrestling with the best strategy at a retreat Thursday and Friday in Virginia. And some have been denying that there is a risk of default if the debt ceiling isn't raised.
Workers dismantle the fence around the remodeled Century theater in Aurora, Colo., in preparation for the cinema's reopening Thursday. The theater's owner sent 2,000 invitations to the private event, being held for victims' families and first responders.
The Aurora, Colo., theater where 12 people were killed in a mass shooting last summer reopens Thursday, with a private event for victims' families and first responders.
