Question
What will happen to the climate, if we stop burning fossil fuels today?
- Earth's normal temperature would continue to increase.
- Temperatures would remain to warm, then start to cool down in 100 years or more.
- Temperatures would keep on fluctuating but continue to be the same on an average.
- Temperatures will not be rising once greenhouse gas concentrations stopped rising.
Hint:
The greenhouse effect is the way in which heat is trapped close to Earth's surface by “greenhouse gases.
The correct answer is: Temperatures will not be rising once greenhouse gas concentrations stopped rising.
- There is general agreement among scientists that when emissions fall to net zero, then the amount of greenhouse gases in the atmosphere will stop increasing. At that point, the global increase in temperature will slow or stop.
