evidence: Ice everywhere—from the high mountains to the polar ice caps—is also changing, and fast. Some impacts of melting ice are felt very directly by communities that live nearby. In the high mountains, like the Andes or the Himalaya, glaciers are retreating at unprecedented rates some 30 percent higher than a few decades ago, the report says. [...] If all countries held themselves to their most ambitious goals, the polar ice sheets would add somewhere between 5 to 23 centimeters to the world’s oceans by 2100 (the mountain glaciers and the expansion of warmer ocean waters would add more). But if we continue on a path similar to today’s, by the end of the century the ice sheet could add much more melt to the oceans: between 11 to 55 centimeters.
