Page 130 - These include the United Nations Environment Programme (UNEP) , the World Meteorological Organization (WMO) , and the International Council of Scientific Unions (ICSU). The most significant recent event has been the establishment by WMO and UNEP of the intergovernmental Panel on Climate Change (IPCO.

The panel was established in 1988 by the World Meteorological Organization and the United Nations Environment Programme. The panel's goals are to (1) review and assess the science relevant to climate change, (2) assess the possible environmental and socioeconomic impacts of climate change, and (3) identify potential response strategies. To address these goals, the panel established...
Page 48 - Hansen commented that •as I testified to the Senate during the 1988 heat wave, the greenhouse effect cannot be blamed for a specific drought, but it alters the probabilities. Our climate model, tested by simulations of climate on other planets and past climates on Earth, indicates that the greenhouse effect is now becoming large enough to compete with natural climate variability.
Page 118 - The potential health and environmental effects of climate change including, but not be limited to the potential impacts on agricultural, forests, wetlands, human health, rivers, lakes, estuaries as well as societal impacts.
Page 63 - ... must always be scrupulous to point out that such opinions are personal value judgments. Finally, the more rapidly climate changes evolve, the more difficult It will be for societies to adapt; and It may be impossible for natural ecosystems to adapt without substantial dislocations or extinctions of some species. The more rapidly greenhouse gases build up, the more difficult it will be for scientists to forecast the outcome reliably. The less we know about the future the less easily we will be...
Page 13 - We are already irrevocably committed to major global change in the years ahead. The elevated concentrations of greenhouse gases produced to date by human activities will persist for many centuries and will slowly change the climate of the earth, regardless of our actions.
