I suggest that we draft an Open Letter addressed to the Participants of the Major Economies Forum on Energy and Climate, who will be at the preparatory session at the US Department of State on April 27-28 in Washington, D.C.
Taking into account Stephen's comments on the body language of Dr Pachauri, it may be wise to make a very brief statement, such as the following: ===== OPEN LETTER TO PARTICIPANTS OF THE MAJOR ECONOMIES FORUM ON ENERGY AND CLIMATE ========== Participants, We, a group of scientists, researchers and other people sharing a strong background and interest in climate change, are concerned that the Forum's sole focus will be on the politics of energy, as seems confirmed by the name of the Forum. Whilst we acknowledge that the politics of energy are vitally important, we believe that a more comprehensive approach to global warming is appropriate, which would include the following three parts: Part A: Emissions reduction Part B: Carbon stock management Part C: Heat transfer and radiation management We are especially worried that there appears to be little or no funding for research and testing regarding part C. Signatories: John Nissen, ... Sam Carana etc. ========= END PROPOSED OPEN LETTER ===================== I invite others to make changes, but suggest that leaving the Open Letter short could make more members of this group willing to sign, while we could always each elaborate in separate articles as to what we each individually propose. Please all make comments and changes as you see fit, but do add your name and just let's try and get more names under the Open Letter this time! Cheers! Sam Carana PS: I'll add details about the Forum below: President Obama Announces Launch of the Major Economies Forum on Energy and Climate http://www.whitehouse.gov/the_press_office/President-Obama-Announces-Launch-of-the-Major-Economies-Forum-on-Energy-and-Climate/ THE WHITE HOUSE Office of the Press Secretary _____________________________________________________________ For Immediate Release March 28, 2009 President Obama Announces Launch of the Major Economies Forum on Energy and Climate The President is pleased to announce today the launch of the Major Economies Forum on Energy and Climate. The Major Economies Forum will facilitate a candid dialogue among key developed and developing countries, help generate the political leadership necessary to achieve a successful outcome at the UN climate change negotiations that will convene this December in Copenhagen, and advance the exploration of concrete initiatives and joint ventures that increase the supply of clean energy while cutting greenhouse gas emissions. President Obama has invited the leaders of 16 major economies and the Secretary General of the United Nations to designate representatives to participate in a preparatory session at the Department of State on April 27-28 in Washington, D.C. The preparatory sessions will culminate in a Major Economies Forum Leaders’ meeting, which Prime Minister Berlusconi has agreed to host in La Maddalena, Italy, in July 2009. The 17 major economies are: Australia, Brazil, Canada, China, the European Union, France, Germany, India, Indonesia, Italy, Japan, Korea, Mexico, Russia, South Africa, the United Kingdom, and the United States. Denmark, in its capacity as the President of the December 2009 Conference of the Parties to the UN Framework Convention on Climate Change, and the United Nations have also been invited to participate in this dialogue.
