Question

If the presence in greenhouse gases in Earth's atmosphere continues to increase at the present rate, scientists predict that in the next 50 to 100 years, atmospheric temperatures could rise by 2oC.

All of these could be consequences of global warming EXCEPT
A) an increase in arid and semi-arid areas on Earth.
B) permanent flooding of low-lying coastal wetlands.
C) an increase in square miles of polar ice covering Earth.
D) a rise in the amount of vegetation found in tundra and taiga regions.

Answer 1

Al of these will be the consequences except C, increase in polar ice. The rise in temperature is already causing the polar ice to melt down. The further increase in temperature will make the situation of the polar ice worse. the rise in vegetation in Tundra and Tyga regions could be seen because they are very cold areas and temperature increase may help vegetations to survive.

Answer 2

Answer: C, increase in polar icee.

Explanation: The rise in temperature is already causing the polar ice to melt down the rise in vegetation in Tundra and Tyga regions could be seen because they are very cold areas and temperature increase may help vegetations to survive.
