If Earth’s average surface temperature continues to change over the next 30 years at the same rate it changed between 1980 and 2010, the average temperature will most likely be around
0.2°C lower than in 1990.
0.6°C higher than in 2010.
the same as it was in 1980.
the same as it was in 2000.

Answer 1

0.6°C higher than in 2010.

Reason: From 1980 to 2010 the average temperature rose by about 0.6°C. If it continues to change at that same rate for the next 30 years (2010→2040), it would increase another ~0.6°C above the 2010 value.
