Hypothetically, How Could Scientists Lower Earth's Temperature in Order to Combat

Question

Hypothetically, how could scientists lower Earth's temperature in order to combat global warming?
A) by moving ice from the Arctic to the tropical oceans
B) by forcibly melting more glaciers and polar ice caps
C) by reflecting more light from land masses
D) by decreasing the reflectance of cities

Accepted Answer

Scientists could lower Earth's temperature by reflecting more light from land masses. This can be achieved by creating reflective surfaces such as white roofs or by planting more reflective crops in agricultural fields. This strategy is known as "albedo modification" and is being researched as a potential way to mitigate the effects of global warming. Option A and B are not feasible solutions as they involve moving or melting large amounts of ice which could have negative consequences for ecosystems and sea levels. Option D is not as effective as increasing reflectivity because urban areas only cover a small portion of Earth's surface.
