"Presumptive Republican presidential nominee Donald Trump told California voters Friday that he can solve their water crisis, declaring, 'There is no drought.'"

"Stonehenge eroding under the forces of extreme weather. The city of Venice slowly collapsing into its canals. The gradual flooding of the Statue of Liberty. Images like these, familiar from Hollywood climate-catastrophe thrillers, were evoked by a joint report, released on Thursday by Unesco, the United Nations Environment Program and the Union of Concerned Scientists, that detailed the threat climate change could pose to World Heritage sites on five continents."

"The University of Massachusetts said it will divest from direct fossil-fuel holdings in its endowment, without specifying the total amount of its investment."

"On a cold rainy day last fall, dozens of people gathered in a plaza across the street from New Jersey's state Capitol. They held press conferences and slept overnight in lawn chairs."
