Key conclusions from the Fourth Assessment Report of the Intergovernmental Panel on Climate Change

27 June 2007 par Bert Metz

We’re in the midst of global warming - (0.8 ∫C warming so far; warmer than last 1300 years)

Anthropogenic greenhouse gas emissions are its main cause

Warming has increased the risk of extreme events - heat waves, droughts, flooding, intensity of tropical storms

Climate change will completely change the world if unchecked - 2-7 ∫C global warming by 2100, risk of "surprises"

Sea level rise:
 20th Century: 15-20 cm
 Current rate: 3 cm per decade
 Until 2100: probably < 1 m
 Centuries: several meters likely
 Regional variation due to ocean circulation

This is the presentation made during the Mini Hearing : Trade and Climate change.
