O'Rourke in Nevada

Climate change is perhaps the greatest challenge facing human civilization, and everyone needs to chip in to solve it, Democratic presidential hopeful Beto O’Rourke told a Reno audience on Thursday.

“We know that this will become worse, and much worse for our kids and grandkids, if we don’t take action,” O’Rourke warned the college-age crowd of hundreds gathered at Bibo Coffee, near the campus of the University of Nevada, Reno. “None of this can be met by half-measures, or even half the country.”
