Climate Change Affects Glaciers

Glaciers and permafrost have been melting gradually, in the early years of the world, but due to the global warming, and climate change in the world today, over the past one hundred years, mountain glaciers almost everywhere in the world have decreased in incredible sizes, and similarly with the amount of permafrost in the Arctic. One specific example, is the idea of Greenland's ice sheet which is melting at a incredible speed at the moment. Another effect of melting glaciers is the sea level, sea level's have been rising dramatically over the years, (about 15cm) due to melting glaciers. Graphs and models predict that the sea level with rise as much as 59cm during the 21st century which would cause flooding and threaten coastal communities and wetlands.
