What causes global sea level rise?
Sea level rise is caused by melting glaciers and ice sheets. Glaciers are very important for the regulation of the global temperature because they reflect sunlight away from the planet keeping temperatures lower. However, since the 1900s, industrialisation and greenhouse gas emissions have caused temperatures all around the world to increase, particularly in the polar regions. With the higher polar temperatures, glaciers and ice sheets melt, causing the sea level around the world to rise by approximately 3mm per year. This has an effect on humans, wildlife, weather and the environment.
