Question

Which of these is evidence of global warming ?

Answer 1

I think option D would be evidence of global warming.

Two major mechanisms are causing sea level to rise. First, shrinking land ice, such as mountain glaciers and polar ice sheets, is releasing water into the oceans. Second, as ocean temperatures rise, the warmer water expands. Trapped within a basin bounded by the continents, the water has nowhere to go but up. 

Which ends up being Global warming.

Hope this helps :)

Answer 2

melting sea ice and ice sheets apex
