GeoSkill


Here you are given a graph and you must carefully examine the x- and y-axes. The title on the graph will tell you what is being displayed.


(a) If we consider the average temperature records from 1880 to 2020, in which decade do we see the most significant increase in global temperatures begin to occur? Tick the correct box below.


History of Global Surface Temperature Since 1880


1.0 0.8 0.6 0.4 0.2 0


–0.2 –0.4


1880 1890 1900 1910 1920 1930 1940 1950 1960 1970 1980 1990 2000 2010 2020 Year


Remember!


What happened in the developed world to cause this temperature increase?
