Climate change

Glacial CalvingClimate change, caused by increasing atmospheric concentrations of greenhouse gases, is driven by human activity. Anthropogenic emissions of carbon dioxide, methane, nitrous oxide, and black carbon are primarily responsible for the changing climate. Burning fossil fuels and clearing natural habitats for human use produce the majority of these emissions. Climate change continues to cause glacial melting in Greenland and the Antarctic, rising sea levels, increases in global mean surface temperatures, increases in extreme weather events, and changes in the abundance, distribution, and composition of species. Climate change and the above ecosystem transformations are inextricably connected; as a result, these changes and impacts mutually exacerbate each other.
