CCA Climate Science & GHG Fundamentals 2

Question 1

Which of the seven greenhouse gases is most commonly referenced when discussing agricultural emissions from livestock?

Accepted Answer

Methane (CH4)

Answer

Methane produced by enteric fermentation in livestock (especially cattle) is the primary GHG associated with agricultural animal husbandry.

Question 2

The 'carbon cycle' describes the process by which:

Accepted Answer

Carbon moves between the atmosphere, oceans, land, and living organisms

Answer

The carbon cycle describes the natural movement of carbon through Earth's systems including photosynthesis, respiration, decomposition, and ocean absorption.

Question 3

What is 'radiative forcing' in climate science?

Accepted Answer

The change in energy flux in the atmosphere caused by natural or anthropogenic factors

Answer

Radiative forcing quantifies the change in energy balance in the Earth's atmosphere resulting from factors such as increased GHG concentrations, expressed in watts per square meter (W/m²).

Question 4

Which sector is the largest source of US greenhouse gas emissions according to the EPA?

Accepted Answer

Transportation

Answer

Transportation surpassed electricity generation as the largest source of US GHG emissions, accounting for approximately 28% of total emissions according to recent EPA data.

Question 5

What is the difference between 'mitigation' and 'adaptation' in climate policy?

Accepted Answer

Mitigation reduces GHG emissions; adaptation adjusts to climate change impacts

Answer

Climate mitigation involves actions that reduce or prevent GHG emissions, while adaptation focuses on adjusting systems and practices to cope with the effects of climate change that are already occurring.
