Which of the following scenarios is likely to result from increased temperatures in the Artic?
Increased melting of the sea ice decreases the sea level and leads to more arable
land area that can be farmed
Increased melting of the permafrost decreases the number of days that large vehicles
can travel over the area to transport drilling equipment to extract oil from the region
Increased numbers of mosquitos drive caribou to lower, warmer elevations to where
there is more vegetation
Increased melting of the sea ice increases travel distance for ships but decreases
the distance that polar bears and other Arctic species have to travel to find food, leading
to their possible population boom
Decreased melting of the permafrost decreases the amount of methane that escapes
into the atmosphere, which decreases the temperature even more
