ozone.org Scientific Consensus on Global Warming There is no longer a substantial debate in the scientific community about whether global warming exists, though a few vocal skeptics keep the vast majority on their toes. In the last decade the debate has shifted from questions of 'If?' and 'How?' to those of 'When?', 'How much?', and 'What impact?' global warming will have. The scientific consensus on global warming grows each year: 1996 - 3,000 scientists of the Intergovernmental Panel on Climate Change (IPCC) coauthored and peer-reviewed a document reviewing the scientific evidence of global warming in the Second Assessment Report of the IPCC. The IPCC concluded that "the balance of evidence suggests a discernable human influence on global climate." The IPCC Third Assessment Report is due to be delivered in 2001. 1997 - 2,500 scientists sign the Scientists' Statement on Global Climatic Disruption declaring that "human induced climate change is underway" adding that the "scale, severity and costs" of the threat inspired their "note of urgency." The group called for "early domestic action to reduce U.S. emissions…" and encouraged other nations to follow suit and that the U.S assist such countries in their efforts. 1997 - Union of Concerned Scientists issues the World Scientists' Call for Action at the Kyoto Summit signed by 1,560 scientists from 65 countries including 109 Nobel laureates. The statement called for "all government leaders to demonstrate a new commitment to protecting the global environment" and pushed for a strong emissions reduction mandate in Kyoto. 1999 - February - The American Geophysical Union issued a policy statement Climate Change and Greenhouse Gases on behalf of its membership citing the evidence of the influence of human activities on global warming while acknowledging the limits on predictive capabilities of climate science. The policy statement says that as "the world may already be committed to some degree of human-caused climate change, and further buildup of greenhouse gas concentrations may be expected to cause further change" and that these changes "could be very disruptive." Finally AGU "believes that the present level of scientific uncertainty does not justify inaction in the mitigation of human-induced climate change and/or the adaptation to it." 1999 - December - NOAA/BMO - Heads of both the National Oceanographic and Atmospheric Administration and the British Meteorological Office in an open letter to newspapers warn that "Ignoring climate change will surely be the most costly of all possible choices, for us and our children." They conclude that the evidence for global warming is " almost incontrovertible, that man has an effect and therefore we need to act accordingly" and called on governments and businesses to move forward with solutions. 2000 - January - A National Academy of Sciences special panel issues a major report on the lingering discrepancy between various global temperature datasets. The report "Reconciling Observation of Global Temperature Change" calls the recent warming trend "undoubtedly real." 2000 - June - U.S. National Assessment Released
