Global warming and climate change

Reasons for global warming

Global warming is the increase in the average temperature of Earth's near-surface air and oceans since the mid-20th century. The Intergovernmental Panel on Climate Change (IPCC) concludes that the main reason for the rise in temperature are the increasing concentrations of greenhouse gases. In the industrial era, human activities have added greenhouse gases to the atmosphere, mainly through the burning of fossil fuels and deforestation.
Climate model projections indicate that the global surface temperature is likely to rise a further 1.1 to 6.4 °C (2.0 to 11.5 °F) during the 21st century.

Consequences

An increase in global temperature will cause sea levels to rise and will probably lead to an expansion of subtropical deserts. Warming is also seen as main reason for the continuing retreat of glaciers and sea ice. Other effects may be an increase in extreme weather events (such as hurricaines, tornadoes and floods) and species extinction.

What can be done?

Political and public debate continues regarding global warming, and what actions (if any) to take in response. The available options are to take measures to reduce further emissions; adaptation to reduce the damage caused by warming. Most national governments have signed and ratified the Kyoto Protocol aimed at reducing greenhouse gas emissions.
