Nobel Peace Prize winner Al Gore is urging governments to speed up the creation of a new treaty to reduce greenhouse gas emissions by two years, suggesting that waiting until the Kyoto pact expires in 2012 is too late. Gore made these comments upon arriving in Oslo to collect his Nobel prize, which he shares with the UN Intergovernmental Panel on Climate Change for their efforts to raise awareness and advance the science of climate change. Gore plans to emphasize the importance of an early treaty both during his acceptance speech in Norway and at the UN climate conference in Bali. The United States rejected the 1997 Kyoto protocol, a main UN climate pact that required 36 nations to reduce emissions. The US argued that the agreement would be too costly and unfairly excluded developing countries from emission cuts. Former Vice President Al Gore expressed disappointment in the US's decision, stating that the country should be leading the charge against climate change. Despite this setback, Gore noted that there were positive signs within the US, such as cities and states adopting Kyoto provisions and 150 business leaders calling for carbon emission reductions. Gore emphasized the importance of individual choices for the environment, such as taking public transportation like the train. In 2006, Gore was ridiculed for taking a limousine to the Cannes film festival where his Oscar-winning film "An Inconvenient Truth" was being shown. The film emphasizes the need for immediate action to combat climate change.
