Popular passages
Page 206 - Convention, stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system. Such a level should be achieved within a time-frame sufficient to allow ecosystems to adapt naturally to climate change, to ensure that food production is not threatened and to enable economic development to proceed in a sustainable manner.
Page 153 - ... projects and activities. Contributing to the awareness of the importance of indigenous concerns was the role played by indigenous peoples and their supporters at the United Nations Conference on Environment and Development (UNCED) held in Rio de Janeiro in June 1992.
Page 300 - The size of this warming is broadly consistent with predictions of climate models, but it is also of the same magnitude as natural climate variability. Thus, the observed temperature increase could be largely due to natural variability; alternatively, this variability and other human factors could have offset a still larger human-induced greenhouse warming.

There are also a number of significant new findings and conclusions...
Page 305 - CH4 emissions from rice agriculture, in particular Japan, India, Australia, Thailand and China, show that the emissions depend on growing conditions, particularly soil characteristics, and vary significantly. While the overall uncertainty in the magnitude of global emissions from rice agriculture remains large, a detailed analysis now suggests significantly lower annual emissions than reported in IPCC 1990.
Page 304 - ... the processes controlling their global budgets. Atmospheric Concentrations and Trends of Long-lived Greenhouse Gases: The atmospheric concentrations of the major long-lived greenhouse gases [carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), chlorofluorocarbons (CFCs), and carbon tetrachloride (CCU)] continue to increase because of human activities.
Page 303 - Any changes in the radiative balance of the Earth, including those due to an increase in greenhouse gases or in aerosols, will tend to alter atmospheric and oceanic temperatures and the associated circulation and weather patterns.
Page 305 - Adipk acid (nylon) production, nitric acid production and automobiles with three-way catalysts have been identified as possibly significant anthropogenic global sources of nitrous oxide. However, the sum of all known anthropogenic and natural sources is still barely sufficient to balance the calculated atmospheric sink or to explain the observed increase in the atmospheric abundance of...
