Which of the following is true about CO_2CO 2
?
A
It does not have much effect on the climate.

B
It is a greenhouse gas.

C
Very little CO_2CO
2
is being emitted now.

D
If we cut CO_2CO
2
emissions by half, the temperature will stop rising.

B.

Explanation:

It has a huge impact on the environment

It is being emitted in large amounts

And if we cut our carbon emissions in half it would delay the risk of raising the global temperature of 1.5 degrees Celsius but half of it would still pumped into the atmosphere along with the carbon dioxide already in the atmosphere.

But it is a greenhouse gas because it helps trap the heat remaining in Earth's atmosphere which is why the Earth is warming.
