To some extent, it was thanks to a miscalculation by the Reagan Administration! In the mid s, I was head of the atmosphere program at what was then called the Environmental Defense Fund.
In October , the UN sponsored an international meeting of scientists on climate change in Villach, Austria. Its conclusion: Increasing concentrations of greenhouse gases could cause an historic rise in global temperature. This was the first international scientific consensus on climate change and an important turning point, but the key question was, "Could this scientific concern be directed toward leveraging government action worldwide"?
Our group hoped to engage governments and the public in a chain of events that would culminate in a "framework convention", a type of treaty suggested by the Villach participants.
To this end, we organized or helped to plan a series of science and policy meetings between and , including the highly visible World Conference on the Changing Atmosphere , sponsored by the Canadian government and held in Toronto in the summer of Also, other groups besides ours, in the US and abroad, were pressing for action on the climate front. Future Risks and Opportunities for Adaptation; and 3.
Managing Future Risks and Building Resilience. It assesses all relevant options for mitigating climate change through limiting or preventing greenhouse gas emissions, as well as activities that remove them from the atmosphere. It lays out a number of baseline scenarios that, without mitigation efforts, would lead to substantial warming by the end of the 21st century.
In its periodic assessments, the Intergovernmental Panel on Climate Change has expressed growing certainty that global warming is underway and that human activity is a principal cause. Tags Science Extreme Weather. Climate Basics » Climate Science. What is the IPCC and why is it important? What is the Fifth Assessment report? AR5 is broken up into three sections, or working groups: Working Group I provides a comprehensive assessment of the physical science basis of climate change: Released Sept.
Working Group II assesses the scientific, technical, environmental, economic and social aspects of vulnerability to climate change as well as consequences for ecological systems, socio-economic sectors and human health: Released March 31, Working Group III assesses all relevant options for mitigating climate change through limiting or preventing greenhouse gas emissions and taking actions to remove them from the atmosphere: Released April 11, The syntheses report was released Nov.
It answers such questions as: What is the state of the science in understanding and attributing climate changes? What are the primary drivers of climate change?
How do recent changes compare to paleoclimatic records? WCRP continues its contributions to the analysis and prediction of climate change as part of Earth system change. The intergovernmental nature of the new assessment body, on the other hand, made it a natural fit within the remit of WMO and UNEP, both intergovernmental organizations.
