Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Most greenhouse models say that the temperature on the surface of the Earth would increase by at least____ over the next century.

A	4-6*c
B	3-5*c
C	5-10*c
D	3-9*c

Explanation:

Detailed explanation-1: -The natural greenhouse effect raises the Earth’s surface temperature to about 15 degrees Celsius on average-more than 30 degrees warmer than it would be if it didn’t have an atmosphere.

Detailed explanation-2: -An increase of five degrees would empty most of the planet’s underground reservoirs of water, making it more difficult yet to grow crops. Competition for the world’s remaining arable land could lead China to invade Russia and the United States to invade Canada.

Detailed explanation-3: -Over the last century, the average surface temperature of the Earth has increased by about 1.0o F. The eleven warmest years this century have all occurred since 1980, with 1995 the warmest on record.

Detailed explanation-4: -In 2015, world leaders finalized the landmark Paris climate agreement. It calls for nations to keep global average temperatures “well below 2 C, ” while “pursuing efforts” to keep them under 1.5 C. In the years since, 1.5 C has become the global goal.
