Key Messages from the Congress
Copenhagen, Denmark: Following a successful International Scientific Congress Climate Change: Global Risks, Challenges & Decisions attended by more than 2,500 delegates from nearly 80 countries, preliminary messages from the findings were delivered by the Congress' Scientific Writing Team. The conclusions will be published into a full synthesis report June 2009. The conclusions were handed over to the Danish Prime Minister Mr. Anders Fogh Rasmussen today. The Danish Government will host the UN Climate Change Conference in December 2009 and will hand over the conclusions to the decision makers ahead of the Conference.
The six preliminary key messages are:
Key Message 1: Climatic Trends
Recent observations confirm that, given high rates of observed emissions, the worst-case IPCC scenario trajectories (or even worse) are being realised. For many key parameters, the climate system is already moving beyond the patterns of natural variability within which our society and economy have developed and thrived. These parameters include global mean surface temperature, sea-level rise, ocean and ice sheet dynamics, ocean acidification, and extreme climatic events. There is a significant risk that many of the trends will accelerate, leading to an increasing risk of abrupt or irreversible climatic shifts.
Key Message 2: Social disruption
The research community is providing much more information to support discussions on "dangerous climate change". Recent observations show that societies are highly vulnerable to even modest levels of climate change, with poor nations and communities particularly at risk. Temperature rises above 2C will be very difficult for contemporary societies to cope with, and will increase the level of climate disruption through the rest of the century.
Key Message 3: Long-Term Strategy
Rapid, sustained, and effective mitigation based on coordinated global and regional action is required to avoid "dangerous climate change" regardless of how it is defined. Weaker targets for 2020 increase the risk of crossing tipping points and make the task of meeting 2050 targets more difficult. Delay in initiating effective mitigation actions increases significantly the long-term social and economic costs of both adaptation and mitigation.
Key Message 4 - Equity Dimensions
Climate change is having, and will have, strongly differential effects on people within and between countries and regions, on this generation and future generations, and on human societies and the natural world. An effective, well-funded adaptation safety net is required for those people least capable of coping with climate change impacts, and a common but differentiated mitigation strategy is needed to protect the poor and most vulnerable.
Key Message 5: Inaction is Inexcusable
There is no excuse for inaction. We already have many tools and approaches – economic, technological, behavioural, management – to deal effectively with the climate change challenge. But they must be vigorously and widely implemented to achieve the societal transformation required to decarbonise economies. A wide range of benefits will flow from a concerted effort to alter our energy economy now, including sustainable energy job growth, reductions in the health and economic costs of climate change, and the restoration of ecosystems and revitalisation of ecosystem services.
Key Message 6: Meeting the Challenge
To achieve the societal transformation required to meet the climate change challenge, we must overcome a number of significant constraints and seize critical opportunities. These include reducing inertia in social and economic systems; building on a growing public desire for governments to act on climate change; removing implicit and explicit subsidies; reducing the influence of vested interests that increase emissions and reduce resilience; enabling the shifts from ineffective governance and weak institutions to innovative leadership in government, the private sector and civil society; and engaging society in the transition to norms and practices that foster sustainability.
About the congress
The International Scientific Congress on Climate Change is taking place in Copenhagen 10 - 12 March. More than 2,000 participants are registered. The congress has received almost 1,600 scientific contributions from researchers from more than 70 countries. The preliminary conclusions from the congress will be presented Thursday 12 March at the closing session of the congress and will be developed in a synthesis report to be published in June this year. The synthesis report will be handed over to all participants at the United Nations Climate Change Conference (COP15) in December in Copenhagen by the Danish Government. It is organized by International Alliance of Research Universities (IARU):
- Australian National University
- ETH Zürich
- National University of Singapore
- Peking University
- University of California, Berkeley
- University of Cambridge
- University of Copenhagen
- University of Oxford
- University of Tokyo
- Yale University
