This policy brief, prepared by the Africa Progress Panel, African Development Bank and UN, outlines the implications of climate change for Africa, emphasising the need for a strong and cohesive negotiating position at the December 2009 climate talks in Copenhagen.

The authors argue that African governments must define practical steps for the international community to address the climate crisis. Three areas require urgent action: clear emissions targets and an adaptation fund; energy-saving technologies through additional financing and technology transfer; and improving long-term frameworks such as the Clean Development Mechanism and reduced emissions from deforestation and forest degradation (REDD).

To achieve this, argue the authors, African heads of state and ministers of finance, planning and environment must collaborate on a practical strategy position to generate maximum buy-in from the rest of the world. This must be achieved in time for high-level meetings in the second half of 2009.

This policy brief, published by the Global Canopy Programme, proposes a system called Proactive Investment in Natural Capital (PINC), to reward countries for conserving large areas of tropical forest that act as 'global utilities' providing ecosystem services essential for preserving global food and energy security.

The authors suggest that the system, could complement current proposals for reducing emissions from deforestation and forest degradation (REDD). They argue that REDD could encourage countries with historically low deforestation rates to destroy their forests. They point out that if REDD successfully brings deforestation rates down — to zero eventually — then in the long-term, countries will not be able to receive payments for reducing deforestation.

The alternative, PINC, would build on existing systems that pay for ecosystem services, such as eco-certification, although scaling-up funding for standing forests is still a challenge, say the authors. To be effective, PINC requires capacity building and improved governance across the world. Land tenure reform will be needed in many countries, as will local participation in decision making and training in forest management. But, if appropriately designed, PINC could provide local communities with co-benefits such as poverty alleviation and biodiversity conservation.

This 'toolkit', published by the World Bank, provides policy advice on how to integrate climate change adaptation strategies into development programs.

It gives an overview of climate change impacts in developing countries and identifies the main channels through which development programs can cost-effectively adapt to climate change and reduce greenhouse gases. The authors identify individual development policies and suggest ways of incorporating mitigation and adaptation measures. They also provide lists of desirable climate outcomes alongside the specific policies needed, by type and sector, to achieve them.

The Third Assessment Report of the IPCC's Working Group 1 builds on past assessments and incorporates new results from the past five years of climate change. It descibes the current state of udnerstanding of the cliamte system, and provides estiamtes of its projected future evolution and their uncertainties.

Many hundreds of scientists from around the world participated in the preparation and review of the report, which states that "there is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities".

The Third Assessment Report of the Intergovernmental Panel on Climate Change, published in 2001, is the most comprehensive and authoritative source of information on climate change. Its conclusions confirm and strengthen those of the previous reports: human-induced climate change is a reality and most of the effects will be negative, but a range of mitigation opportunities is available to address the problem.

The Report finds that most of the earth’s warming over the past 50 years can be attributed to human activities, and that its effects are already being felt. Global temperature is expected to increase by 1.4 to 5.8ºC over the next century, a significant increase on the projections of the 1995 Second Assessment Report. This briefing paper summarises the findings of the Third Assessment Report and the debates underpinning them, and discusses the likely outcomes of the Report.
