global warming

The Earth’s climate system has demonstrably changed on both global and regional scales…
  • there is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities;


  • human activities have increased the atmospheric concentrations of greenhouse gases and aerosols since the pre-industrial era;


  • the key greenhouse gases are carbon dioxide (CO 2), methane (CH4), nitrous oxide (N2 O), and fluorinated gases - i.e. hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulphur hexafluoride (SF6) - all of which are covered by the Kyoto Protocol*, and also tropospheric ozone (O3).


* The IPCC, the Intergovernmental Panel on Climate Change, is the United Nations agency that issued reports on the state of research in 1990, 1995, and 2001. Its 1995 review was a prime driver behind the Kyoto Accords (see following facts sheets).
