Obama: Shrinking Exit Glacier a powerful sign of warming climate

By Roberta Rampton SEWARD, Alaska (Reuters) – President Barack Obama walked down a winding wooded path, past a small brown post marked “1926” and a glacial stream trickling over gravel that eons of ice have scraped off mountain peaks. “This is as good a signpost of what we’re dealing with on climate change as just about anything,” Obama told reporters near the base of the glacier. It was the signature moment of Obama’s trek to Alaska, aimed at making the world pay heed to the damage already caused by rising seas, and demand global leaders reach a deal in Paris in December to curb climate-changing carbon emissions.
