Mule deer are seen in the snow during a late spring snow storm in Golden, Colorado May 11, 2014. A Mother's Day snowstorm blanketed the Northern Rockies on Sunday, prompting road closures in Colorado and Wyoming, and the same weather system prompted tornado watches in several Midwestern states as it moves eastward, officials said.

Demonstrators use boats on the river Spree during a protest for Germany's shift to green energy and away from nuclear power and fossil fuels in Berlin May 10, 2014. Environmental groups and supporters rallied on Saturday against nuclear energy, the expansion of fossil fuel power stations and what organisers said was a backtracking of the German government on the country's planned energy transition, the shift from conventional forms of energy sources to the use of renewable means of energy generation.
