From the page: "Yet the idea that climate change equals consistently hotter temperatures was dispelled long ago. 'Global warming,' which refers to long-term warming of the planet, can be a somewhat misleading term when applied to climate science, since "climate change" encompasses both hot and cold temperature extremes. According to NASA, climate change 'includes warming, cooling, and changes besides temperature.'
After an extreme winter storm in the Northeast earlier this month, the AP reported that warmer winters punctuated by strong blizzards are consistent with climate change. Warmer temperatures cause a buildup of moisture in the atmosphere, which leads to snowier days during the winter."
