This is because climate change is expected to increase the frequency of extreme weather events - though linking any single event to global warming is complicated. This includes the release of large quantities of methane as permafrost - frozen soil found mainly at high latitudes - melts. The effects of a changing climate can also be seen in vegetation and land animals. past five years, 2015–2019, were the warmest on record. The American pika, for example, is a small mammal that lives in cool mountainous areas in western North America—in fact, it can die when exposed to temperatures warmer than 78˚F.So as the mountain climate heats up, the pika climbs the slopes in search of cooler habitat.
