ALASKA-Seeking to lend urgency to his climate agenda, President Barack Obama warned Monday that even ramped-up efforts to curb emissions were being outpaced by the effects of a warming planet. And he warned those who doubt scientists’ assertions that humans are responsible for a warming planet that their views are increasingly untenable. “We know that human activity is changing the climate,” Obama said in Anchorage, Alaska. “We know that human ingenuity can do something about it. We’re even starting to see that we might actually have the political will to succeed. So the time to heed the critics and cynics is past. The time to plead ignorance is surely past. The deniers are increasingly alone, on their own shrinking island.” Obama is visiting Alaska this week to underscore the areas global warming is already disrupting life, including melting glaciers and more severe wildfires.(CNN NEWS/ ksat.com)…[+]
