There is great debate among many people, and sometimes in the news, on whether global warming is real. But climate scientists looking at the data and facts agree the planet is warming.  The scientific theory on climatic changes related to global warming is that the average temperature of the Earth has risen between 0.4 and 0.8 °C over the past 100 years. The increased volumes of carbon dioxide and other greenhouse gases released by the burning of fossil fuels, land clearing, agriculture, and other human activities, are believed to be the primary sources of the global warming that has occurred over the past 50 years. Scientists from the Intergovernmental Panel on Climate carrying out global warming research have recently predicted that average global temperatures could increase between 1.4 and 5.8 °C by the year 2100. Changes resulting from global warming may include rising sea levels due to the melting of the polar ice caps, as well as an increase in occurrence and severity of storms and other severe weather events.]]> 2017-06-01 12:00:58 UTC https://padlet.com/19rosini/yka4qcljonr6/wish/174793994 19rosini https://padlet.com/19rosini/yka4qcljonr6/wish/174794001 scientists learned that there are several greenhouse gases responsible for warming, and humans emit them in a variety of ways. Most come from the breaking down of fossil fuels in cars, factories and electricity production. The gas responsible for the most warming is carbon dioxide, also called CO2. Other contributors include methane released from landfills and agriculture, especially from the digestive systems of grazing animals, nitrous oxide from fertilizers, gases used for refrigeration and industrial processes, and the loss of forests that would otherwise store CO2.]]> 2017-06-01 12:01:01 UTC https://padlet.com/19rosini/yka4qcljonr6/wish/174794001
