Practice Test: Environment- 1 - Question 4

Which of the following appears to contribute to global cooling rather than global warming?

Detailed Solution for Practice Test: Environment- 1 - Question 4

Aerosols have a profound impact on the climate because, just like greenhouse gases, they are able to change the Earth’s “radiative”, or energy, balance. Aerosols can control how much energy from the sun reaches the planet’s surface by changing the amount that is absorbed in the atmosphere and the amount that is scattered back out to space. It turns out that most aerosols are cooling — that is to say, they reflect the sun’s energy back out into space. There is only one aerosol — soot, also known as black carbon — that actually helps contribute to global warming by boosting the warming effects of greenhouse gases in the atmosphere.
