The majority of the scientific community is in agreement that increasing atmospheric concentrations of carbon dioxide and other greenhouse gases as a direct result of human activity is causing a global change in climate. Between 1906 and 2005, the global average near-surface air temperature increased by 0.74°C. It is expected that global average near –surface air temperature will further increase in the years to come, despite efforts to reduce greenhouse gas emissions through mitigation actions.
