What is a key feature of Ice Sheet climates?

Ice Sheet climates are characterized by consistently below freezing temperatures due to their unique geographical and environmental conditions. These regions, which include large areas of Greenland and Antarctica, experience extremely cold temperatures year-round, which supports the formation and maintenance of thick ice sheets. The sustained below-freezing temperatures prevent the melting of ice, allowing it to accumulate and shape the landscape.

In contrast, warm and humid summers would be typical of a different climate type, likely resulting in melting and potentially disintegration of ice sheets. Frequent thunderstorms are generally associated with warmer and more humid climates, not the cold, stable, and arid conditions found in Ice Sheet climates. Additionally, high amounts of annual rainfall do not correlate with Ice Sheet climates, where the precipitation typically falls as snow, but overall, these regions receive relatively low annual precipitation compared to other climate types.
