Carbon dioxide is not the only greenhouse gas of concern.

Question

BlackTom AI · Accepted Answer

The statement to evaluate is: 'Carbon dioxide is not the only greenhouse gas of concern.'
Option 1: True. This is accurate because while carbon dioxide is a major greenhouse gas contributing significantly to anthropogenic warming, there are several other important greenhouse gases as well. These include methane (CH4), nitrous oxide (N2O), ozone (O3) in the troposphere, water vapor (H2O), and a range of fluorinated gases (such as CFCs, HCFCs, HFCs, PFCs, and SF6). Each of these gases has its own global warming potential and atmospheric lifetime, and together they contribute to the overall greenhouse effect. Thus, CO2 is not the sole greenhouse gas of concern.
Option 2: False. This statement would be incorrect because it implies that CO2 is the only greenhouse gas of concern. In reality, multiple greenhouse gases contribute to climate forcing, with varying abundances, lifetimes, and warming potentials. Recognizing the role of other gases is essential for understanding the full picture of climate change and for designing effective mitigation strategies.
In summary, the assertion that carbon dioxide is not the only greenhouse gas of concern aligns with the established scientific understanding of atmospheric radiative forcing and the array of gases involved in the greenhouse effect.
