High concentration of green house gases has resulted in maximum rise of atmospheric temperature in
tropic region
middle latitude
polar region
temperate region
As discussed in Global warming -
Increases in the level of greenhouse gases has led to considerable heating of earth leadding to global warming. During the past century, the temperature of earth has increased by 0.6oC , most of it during the last three decades. Rise in temperature is slight in tropics , moderate in middle latitudes and maximum in polar regions. It will led to melting of polar ice caps as well as of other places like the Himalayan snow caps.
Hence, the correct option is (c).
