According to a 2009 study, the continent-wide average surface temperature trend of Antarctica is positive and significant at >0.05 °C/decade since 1957. West Antarctica has warmed by more than 0.1 °C/decade in the last 50 years, and this warming is strongest in winter and spring. Although this is partly offset by fall cooling in East Antarctica, this effect is restricted to the 1980s and 1990…

Previously, scientists have highlighted the importance of subsurface ocean melting as a key process, which can trigger runaway effects in the major marine-based ice sheets in Antarctica. WebOct 18, 2024 · Although most people do not look out their window and see a frozen tundra, the cryosphere impacts everyone. Some communities are directly impacted by the cryosphere — they rely on frozen ice to travel and hunt, or to get their water from melting snow and glacier runoff. Other communities feel the impact of the cryosphere less directly.
