1. What is the primary greenhouse gas responsible for the enhanced greenhouse effect?

Carbon Dioxide

Explanation

Main driver of global warming.

9. What is the primary natural source of methane emissions?

Wetlands

Explanation

Microbial activity in waterlogged soils.

21. Which greenhouse gas is released during the combustion of fossil fuels and biomass?

Carbon Dioxide

Explanation

Primary product of burning organic matter.

2. Which human activity is a significant contributor to the increase in atmospheric methane concentrations?

Rice cultivation

Explanation

Methane released from flooded rice paddies.

3. What is the Keeling Curve used to monitor?

Greenhouse gas concentrations

Explanation

Graph showing rising CO2 levels over time.

6. What is the main source of anthropogenic nitrous oxide emissions?

Agricultural activities

Explanation

Fertilizer use, livestock farming, etc.

8. In the context of greenhouse gas concentrations, what is the 'pre-industrial' baseline typically used as a reference?

1700-1750

Explanation

Era before significant human emissions.

11. What is the primary driver of increased carbon dioxide concentrations in the atmosphere?

Burning of fossil fuels

Explanation

Burning coal, oil, and gas releases CO2.

4. Which greenhouse gas is considered a 'short-lived climate pollutant'?

Methane

Explanation

Short atmospheric lifespan, potent warming effect.

#10

5. How does the phenomenon of 'radiative forcing' relate to greenhouse gases?

It measures the warming effect of greenhouse gases on the Earth's surface

Explanation

Quantifies heat trapped by greenhouse gases.

#11

7. Which greenhouse gas is primarily responsible for stratospheric ozone depletion?

Chlorofluorocarbons (CFCs)

Explanation

Break down ozone, thinning the ozone layer.

#12

10. Which greenhouse gas is most effective at trapping infrared radiation per molecule?

Water Vapor

Explanation

Abundant in the atmosphere, strong absorber.

#13

12. Which international agreement aims to address climate change by limiting global warming?

Paris Agreement

Explanation

Agreement to limit global temperature rise.
