Gateway to the UN System's Work on Climate Change - The Earth's Changing Climate Warming more and faster — The rate of warming of the Earth’s average surface temperature over the last 50 years was nearly twice the rate for the last 100 years. Over the past 100 years, the Earth’s average surface temperature rose by around 0.74°C. If atmospheric concentrations of the dominant greenhouse gas, carbon dioxide, were to double compared to pre-industrial level, this would lead to an average warming of around 3°C. The late 1990s and early 21st century had the warmest years since modern records began. Arctic sea ice has been shrinking on average by 2.7 per cent per decade.

Marine species affected by climate change include plankton - which forms the basis of marine food chains - corals, fish, polar bears, walruses, seals, sea lions, penguins, and seabirds. The Intergovernmental Panel on Climate Change predicts a further rise of between 1.4°C and 5.8°C by the end of the century. Climate change could therefore well be the knock-out punch for many species which are already under stress from overfishing and habitat loss.
