An Open Letter on Climate Change Science to all Canadian Elected Government Leaders

June 2008

Twenty years ago, Canada, as a leader in international environmental issues, hosted a conference in Toronto entitled "Our Changing Atmosphere: Implications for Global Security" The participants concluded that: "Humanity is conducting an unintended, uncontrolled, globally pervasive experiment, whose ultimate consequences are second only to global nuclear war."

Two years ago, climate science leaders from the academic, public and private sectors across Canada, conveyed in a letter to the Prime Minister their views on the current state of knowledge of climate change and called for national leadership in addressing the issue.

In our opinion, tackling climate change has become an even more urgent concern since that 2006 letter.

The Fourth Assessment Report of the Intergovernmental Panel on Climate Change placed before the global community definitive scientific evidence regarding the threat of climate change.

In awarding the 2007 Nobel Peace Prize to IPCC, the Nobel Committee, a committee of the Norwegian Parliament, framed climate change as an issue of global peace and security. It stated "Action is necessary now, before climate change moves beyond man’s control."

New analyses show that global greenhouse gas concentrations are increasing, sea level rising and Arctic sea ice decreasing faster than projected only a few years ago. Water shortages are predicted in the western Prairies, the Okanagan and in the Great Lakes basin. Earlier targets to avoid human interference with the climate system are now seen to be inadequate.

Addressing greenhouse gas emissions will require a polluter-pay approach and absolute emission caps. Adaptation to the inevitable impacts of climate change is now imperative and we need a national adaptation strategy to minimize those impacts and gain whatever benefits there may be. We are concerned that the pace with which action is being taken in Canada does not reflect adequately the urgency of the threat.

Finally, we believe that sound policy continues to require good scientific input. There is need for further investments in research and systematic monitoring to track the rate and nature of changes, to understand what is happening now, to refine projections of future changes and to analyse the opportunities and threats presented by these changes.

In less than 18 months, the global community will convene in Copenhagen to put in place a new agreement to address climate change. We sincerely hope that, based on the compelling science at hand, our political leaders display the urgency and determination that we believe is required.

Yours sincerely:

Signed by 130 Canadian climate science leaders from the academic, public and private sectors across the country
