Understanding Climate Change

 What is climate change?

Climate change or “global warming” refers to the increase in average temperature of the earth’s climate system since the mid-twentieth century. The rise in temperature results from the release of greenhouse gases (GHGs) into the atmosphere, including carbon dioxide, methane and nitrous oxide. At lower levels of emissions, the burning of fossil fuels would ordinarily be absorbed by vegetation and the oceans. The historically unprecedented concentration of GHG emissions since the mid-twentieth century has meant that more carbon is being stored in the earth’s atmosphere, which is thought to be the leading cause of the temperature increase.
