Climate Change

In the last century, average global air temperature has increased by about 0.7°C (1.3°F). This increase in temperature is causing glaciers to recede on all continents, a major source of freshwater to millions of people, and extreme weather events to become more frequent and intense, for example, Hurricanes Katrina and Sandy (Intergovernmental Panel on Climate Change, 2007).
