Melting Ice: Regional Dramas, Global Wake-Up Call
Former Vice President
TROMSO,
The Arctic is already being affected by climate change, with temperatures rising twice as fast as the global average. A changing Arctic in turn affects the global climate. Polar sea ice in the Arctic reflects much of the incoming solar energy. As the ice melts, this energy is absorbed by the ocean, leading to more warming with global effects. Large-scale melting of the
The situation in the Arctic can be seen as a warning to the rest of the world. Climate change scientists say that over the next few decades, 1.3 billion people will be threatened by more serious flooding, followed by the loss of drinking water, as their rivers swell and then dry up. Many of the world’s main rivers depend on meltwater from the mountains for part of the year. Scientists predict that ice and snow in the mountains that feed these rivers will melt away because of global warming. Rivers flowing from the Himalayas, the Andes Mountains, the Rocky Mountains and the Alps will be affected. In
