Facts about Climate Change

Consider these facts from The Intergovernmental Panel on Climate Change (IPCC), an objective scientific panel set up at the request of United Nation member governments:

  1. Each of the last three decades has been successively warmer, and the period from 1983 to 2012 was likely the warmest 30-year period of the last 1400 years.
  2. Since the beginning of the industrial era, oceanic uptake of CO2 has resulted in a 26% increase in acidification of ocean surface water, which poses substantial risks to marine ecosystems, especially polar ecosystems and coral reefs from phytoplankton to animals.
  3. Arctic sea-ice extent has decreased in every season and in every successive decade since 1979.
  4. Since 1870, sea levels have risen approximately 7.5 inches.
  5. Impacts from recent climate-related extremes, such as heat waves, droughts, floods, cyclones and wildfires, reveal significant vulnerability and exposure of some ecosystems and many human systems to current climate variability.
