Why does global warming occur in the polar regions?

Answer 1

Global climate change is the same at the poles as anywhere else in the world. The frequent newspaper stories would seem to indicate that the changes in the multiyear sea ice cover, permafrost melting, polar bear habitat loss, penguin breed area loss, calving glaciers and such are a unique phenomenon at the poles because of climate change. they are not, they are unique because these are the areas where these unique animals and geophysical situations exist to be affected.

Climate change impacts in the rest of the world such as the northern movement of Humboldt squid, droughts, extreme weather conditions, northward movement of plant and insect species, glacier losses in Canada and the US (and elsewhere in the world) just don't get the press that the polar losses and impacts do.

Answer 2

Global warming occurs in the polar regions because the winds blow carbon dioxide (CO2) and other greenhouse gases all round the world. So emissions from one country are shared around, even to the countries with a very low carbon dioxide footprint. This is why everyone must act.
