Evidence for climate change Flashcards
drilling ice cores helps scientists examine past climate change. where do the scientists go to do the drilling?
A field site in Antarctica
what has been trapped inside the ice that has been drilled?
bubbles of ancient atmosphere
what do the scientists measure in drilling the ice?
the greenhouse gases
what are the scientists trying to establish from drilling the ice?
the past temperatures of the earth and how much they have changed as evidence for climate change.
how might global sea levels be changing?
the levels are rising due to the glaciers and ice caps melting
how are mountain glaciers changing?
the glaciers are melting due to warmer temperatures which shrink the ice
how are low lying islands at risk? give an eg
islands like the Maldives are at risk due to rising sea levels which could potentially submerge these low lying islands one day
what are fossil fuels used for?
in homes they are used to produce heat, in power stations they are used to produce electricity
