Question

1. what is the result of greenhouse gas emissions?

a. cleaner air
b. global warming
c. increased rainfall
d. reduced biodiversity

Explanation:

Greenhouse gas emissions trap heat in the Earth's atmosphere, leading to a rise in global average temperatures, which is defined as global warming. Cleaner air is not a result of greenhouse gas emissions (they pollute the air). Increased rainfall is not a direct primary result, and reduced biodiversity is a consequence of climate change (like global warming) but not the direct result of emissions themselves. So the correct option is b.

Answer:

b. Global warming
