Which scenario is least likely to result from a warmer climate?

The scenario of more moderate weather is least likely to result from a warmer climate because climate change is associated with increased energy in the atmosphere, which tends to enhance weather variability rather than create stability. As temperatures rise, the potential for severe weather events also increases, leading to more extreme weather patterns.

Warmer conditions contribute to increased evaporation rates and altered precipitation patterns, often resulting in more intense storms and a higher frequency of droughts in different regions. As climate systems become more erratic due to increased atmospheric heat, the tendency is towards extremes—such as severe storms, heavy rainfall, and prolonged dry spells—rather than a return to a more moderate climate. Hence, the expectation of moderation contradicts the established understanding of climate change dynamics.
