Global warming refers to climate change as a result of greenhouse gases. Some experts believe that if we don't make an effort to stop air pollution and the release of greenhouse gases, the climate change from global warming will change the world.
Global warming is the rise of temperatures throughout the Earth. Some examples of global warming include:
A .8 degrees Celsius increase in the Earth's temperature since pre-industrial times.
A global average temperature rise of 2 degrees Celsius or less in coming years. In 2010, 200 nations agreed to limit the global average temperature rise to these levels to try to avoid the dangers of climate change. However, meeting this goal may be difficult as scientists warn that more fossil fuels are being burned and more greenhouse gases are being emitted.
The rising of the sea levels throughout the world.
Widespread decreases in the extent of snow and ice.
Warming of the Earth at high northern latitudes. Some warming is expected to occur over the Southern Oceans and the Northern Atlantic, but most warming will be occurring in Northern areas.
The unfreezing and de-icing of the Arctic by September 2037.
The melting of the polar ice caps.
These are the current or expected effects of global warming that some experts observe or predict with reasonable certainty.
