FILE - In this Jan. 1. 2017 file photo, confetti falls as people celebrate the new year in New York's Times Square. This year's New Year's Eve celebration in Times Square will spotlight efforts to combat climate change when high school science teachers and students press the button that begins the famous 60-second ball drop and countdown to next year. “On New Year’s Eve, we look back and reflect on the dominant themes of the past year, and seek hope and inspiration as we look forward," Times Square Alliance President Tim Tompkins said in a statement Saturday, Dec. 28, 2019 announcing the plan. He said the honorees “are working to solve this global problem through science.” (AP Photo/Craig Ruttle, File)

In this Oct. 17, 2019, photo provided by the U.S. Fish and Wildlife Service, a pile of recently dead freshwater mussels are piled along the shore of the Clinch River near Wallen Bend, Tenn. While freshwater mussels have been plagued for decades by habitat loss, invasive species, pollution, sedimentation and other issues, there's a possibility that the die-off in the Clinch River could be connected to infectious disease.

In this May 10, 2019 photo, grain bins belonging to Brett Adams are surrounded by flood waters, in Peru, Neb. Adams had thousands of acres under water, about 80 percent of his land, this year. The water split open his grain bins and submerged his parents' house and other buildings when the levee protecting the farm broke. (AP Photo/Nati Harnik)

FILE - In this June 13, 2012, file photo, Asian carp, jolted by an electric current from a research boat, jump from the Illinois River near Havana, Ill. Sport fish have declined significantly in portions of the Upper Mississippi River infested with Asian carp, apparently confirming fears about the invaders' threat to native species, according to a newly released study. Analysis of more than 20 years of population data suggests the carp are out-competing fish prized by anglers, such as yellow perch, bluegill, and black and white crappie, the report said.
