Popular passages
Page 570 - The scientific understanding of climate change is now sufficiently clear to justify nations taking prompt action. It is vital that all nations identify costeffective steps that they can take now, to contribute to substantial and long-term reduction in net global greenhouse gas emissions.
Page 406 - IPCC assessment report notes that "an increasing body of observations gives a collective picture of a warming world and other changes in the climate system...
Page 756 - The IPCC's conclusion that most of the observed warming of the last 50 years is likely to have been due to the increase in greenhouse gas concentrations accurately reflects the current thinking of the scientific community on this issue.
Page 66 - Climate change' means a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods.
Page 251 - Hemisphere indicate that the increase in temperature in the 20th century is likely to have been the largest of any century during the past 1000 years. It is also likely that, in the Northern Hemisphere, the 1990s was the warmest decade and 1998 the warmest year.
Page 442 - Council, they were responsible for making certain that an independent examination of this report was vn carried out in accordance with institutional procedures and that all review comments were carefully considered. Responsibility for the final content of this report rests entirely with the authoring committee and the institution.
Page 422 - The A2 storyline and scenario family describes a very heterogeneous world. The underlying theme is self-reliance and preservation of local identities. Fertility patterns across regions converge very slowly, which results in continuously increasing population. Economic development is primarily regionally oriented and per capita economic growth and technological change more fragmented and slower than other storylines.
Page 408 - Hence, it is physically plausible to expect that over a short time period (eg, 20 years) there may be differences in temperature trends. In addition, spatial sampling techniques can also explain some of the differences in trends, but these differences are not fully resolved.
Page 66 - The Parties should protect the climate system for the benefit of present and future generations of humankind, on the basis of equity and in accordance with their common but differentiated responsibilities and respective capabilities.
Page 413 - Confidence In the ability of models to project future climate has Increased. Complex physically-based climate models are required to provide detailed estimates of feedbacks and of regional features. Such models cannot yet simulate all aspects of climate (eg, they...
