The report provides a stark account of the threat posed by global warming. It argues that the world is drifting towards a "tipping point" that could lock the world’s poorest countries and their poorest citizens in a downward spiral, leaving hundreds of millions facing malnutrition, water scarcity, ecological threats, and a loss of livelihoods.
The report comes at a key moment in negotiations to forge a multilateral agreement for the period after 2012—the expiry date for the current commitment period of the Kyoto Protocol. It calls for a “twin track” approach that combines stringent mitigation to limit 21st Century warming to less than 2°C (3.6°F), with strengthened international cooperation on adaptation.
On mitigation, the authors call on developed countries to demonstrate leadership by cutting greenhouse gas emissions by at least 80% of 1990 levels by 2050. The report advocates a mix of carbon taxation, more stringent cap-and-trade programmes, energy regulation, and international cooperation on financing for low-carbon technology transfer.
Turning to adaptation, the report warns that inequalities in ability to cope with climate change are emerging as an increasingly powerful driver of wider inequalities between and within countries. It calls on rich countries to put climate change adaptation at the centre of international partnerships on poverty reduction.
