Why are there melting glaciers in Patagonia and Canada and Greenland?

Climate change would be my educated guess. The rays that hit the Earth used to be able to get out of the atmosphere. Now with all the air pollution the heat rays are being locked under the atmosphere, basically where us humans are located. In result the earth is warming up. Patagonia, Canada and Greenland are not the only places suffering. For example the Himalayas glaciers are melting which is a huge problem for the people on the banks who use that water to bathe and to drink. I know this wasn't part of your question, but if we don't be careful, sea levels will rise massively which could result in flooding coastlines. Think about the Netherlands! they are BELOW sea level.
