Page 140 - the balance of evidence suggests a discernible human influence on global climate' [5], and was sufficiently confident by the time of the Third Assessment Report to conclude that 'there is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities...
Page 129 - describe and understand the interactive physical, chemical, and biological processes that regulate the total earth system, the unique environment that it provides for life, the changes that are occurring in this system, and the manner in which they are influenced by human actions.
Page 152 - Bl storyline and scenario family describes a convergent world with the same low population growth as in the Al storyline, but with rapid changes in economic structures toward a service and information economy, with reductions in material intensity, and the introduction of clean and resource-efficient technologies.
Page 137 - In the mid- and high latitudes of the Northern Hemisphere over the latter half of the 20th century, it is likely7 that there has been a 2 to 4% increase in the frequency of heavy precipitation events.
Page 141 - In the light of new evidence and taking into account the remaining uncertainties, most of the observed warming over the last 50 years is likely to have been due to the increase in greenhouse gas concentrations.
Page 55 - 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 137 - It is very likely7 that precipitation has increased by 0.5 to l% per decade in the 20th century over most mid- and high latitudes of the Northern Hemisphere continents, and it is...
Page 65 - 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 increase could be largely due to this natural variability; alternatively this variability and other human factors could have offset a still larger human-induced greenhouse warming...
Page 56 - ... about 10% in the extent of snow cover since the late 1960s, and ground-based observations show that there is very likely to have been a reduction of about two weeks in the annual duration of lake and river ice cover in the mid- and high latitudes of the northern hemisphere, over the 20th century.
