This document provides a brief overview of Dr. Thompson's talk on records of changes in climate in general and the most significant implications of the ice core records of past climate changes in particular. Because climate processes that have operated in the past continue to operate today, ice core records are providing very valuable insights. Within the last two decades, long cores of glacial ice have been used to establish and improve the record of past changes in climate. Analysis of ice cores from Antarctica, Greenland and tropical and subtropical areas have provided a wealth of detailed information on past climate changes. As the ice in these glaciers and ice sheets grew over time, layer by layer, tiny pockets of air were trapped within each layer, preserving a continuous record of the natural changes in the concentrations of greenhouse and other gases. In addition, these ice cores have preserved indirect/proxy records of changes in temperature (which can be closely estimated from the isotopic record of oxygen trapped in the ice), in the concentration of windblown dust, and in volcanic activity. By combining this information, these ice cores have preserved a 200,000-year history of climate changes and factors contributing to these …

The main actions of the Panel includes acceptence of revised 1996 IPCC guidelines for National Greenhouse Gas Inventories, the election of the Chairman-elect, and approval of the program and budget for 1997.

The Panel approved various draft reports including the draft report of the 12th session. The Panel noted the draft decision paper (introduced by Dr. Watson) on the TAR, and after extensive discussions and amendments, the panel approved the decision line by line. The panel deferred the decision on the adoption procedure for the the report underlying the summary for policymakers of the synthesis report.

The report of the Intergovernmental Panel on Climate Change of 1995 has been taken as a starting point. Since 1995 many new observations and reports have become available. Much of the information on observations and studies on climate change and its impacts can be found through the Internet. Where possible we have made references, such that the reader can easily verify and review our sources. This study addresses three main questions: To what extent can the human influence on the climate system presently be measured? What can we expect for the short term and long-term future? To what extent will measures to reduce net greenhouse gas emissions affect the future climate?

This report, prepared under the auspices of the President's National Science and Technology Council (NSTC), highlights the Program's recent research and describes future plans and goals. The U.S. Global Change Research Program (USGCRP) was established in 1989 and authorized by Congress in the Global Change Research Act of 1990. The first edition of Our Changing Planet was transmitted to the Congress as a supplement to the FY1990 budget. In just over a decade, the USGCRPhas generated remarkable improvements to our knowledge of Earth's global-scale environmental processes and helped identify and explain the causes and consequences of a series of global environmental changes, including ozone depletion and climate change.

An act to add Chapter 6 (commencing with Section 42800) to Part 4 of Division 26 of the Health and Safety Code, and to add Chapter 8.5 (commencing with Section 25730) to Division 15 of the Public Resources Code, relating to air pollution.

Bill introduced by the California Senate to revise the functions and duties of the California Climate Action Registry and requires the Registry, in coordination with CEC to adopt third-party verification metrics, developing GHG emissions protocols and qualifying third-party organizations to provide technical assistance and certification of emissions baselines and inventories. SB 527 amended SB 1771 to emphasize third-party verification.

Proceedings of a workshop to discuss coral reef research, monitoring, and marine protected area (MPA) management. It includes workshop summary information, specific papers presented during the event, and relevant appendixes.

This book is a series of reports summarizing discussions and recommendations from a series of forums about strategies to deal with natural disaster. The focus is on changing human behavior and development in order to coexist with natural phenomena rather than trying to control natural phenomena.

This document, which is produced annually, describes the activities and plans of the U.S. Global Change Research Program (USGCRP), which was established in 1989 and authorized by Congress in the Global Change Research Act of 1990. Strong bipartisan support for this inter-agency program has resulted in more than a decade's worth of scientific accomplishment. "Because there is considerable uncertainty in current understanding of how the climate system varies naturally and reacts to emissions of greenhouse gases and aerosols, current estimates of the magnitude of future warming should be regarded as tentative and subject to future adjustments (either upward or downward). Reducing the wide range of uncertainty inherent in current model predictions of global climate change will require major advances in understanding and modeling of both (1) the factors that determine atmospheric concentrations of greenhouse gases and aerosols, and (2) the so-called 'feedbacks' that determine the sensitivity of the climate system to a prescribed increase in greenhouse gases. There is also a pressing need for a global system designed for monitoring climate. Climate projections will always be far from perfect. Confidence limits and probabilistic information, with their basis, should always be considered as an integral part of the information that climate …

Different speakers addressed the Panel. Among other issues, the Eighteenth Session of the IPCC decided that its work must continue to maintain its high scientific and technical standards, independence, transparency and geographic balance, to ensure a balanced reporting of viewpoints and to be policy relevant but not policy prescriptive or policy driven.

Normal temperatures and precipitation levels for your area may have changed as the National Oceanic and Atmospheric Administration's National Climatic Data Center recently released new 'normal' data for about 8,000 weather stations. The data defines the normal temperature at locations across the United States, Puerto Rico, the Virgin Islands and U.S. Pacific Islands. These data are used as a benchmark for weather forecasters to calculate day-to-day temperature and rainfall departures from typical levels and are also used by business, government and industry for planning, design and operations.

El Niño is an abnormal warming of the ocean temperatures across the eastern tropical Pacific that affects weather around the globe. El Niño episodes usually occur approximately every four-five years. NOAA researchers and scientists are presently monitoring the formation of a possible weak El Niño and predict that the United States could experience very weak-to-marginal impacts late winter to early spring 2002.

This report discusses different perspectives used to consider issues related to the global climate change and issues related to the 1992 U.N. Framework Convention on Climate Change and the 1997 Kyoto Agreement.

This Science Plan is mainly concerned with the current extinction crisis on Earth, which, unlike its predecessors, is occurring at an unprecedented rate, is the direct result of human activities and is occurring at all levels at which diversity is measured - from the genetic diversity of many natural and domesticated species to the diversity of ecosystems and landscapes, through the tremendous richness of species. Current human-induced rates of species extinction are estimated to be about 1,000 times greater than past background rates. Biodiversity is the variety of life on Earth. Scientists commonly measure and describe this variety at the level of genes, species and ecosystems, but scientific interest in biodiversity goes far beyond describing and measuring it. The DIVERSITAS programme was founded to address the scientific questions that need to be answered in order to understand how biodiversity supports life on Earth, what the impacts of the present loss of biodiversity are for human and ecosystem survival and how humans can sustainably use and conserve biodiversity.

This report presents recommendations to change the NEPA implementation process, based on the review of an appointed task force.

An Act To Provide Leadership in Addressing the Threat of Climate Change.

An act to establish the legislative commission on global climate change: to direct the commission to study issues related to global warming, the emerging carbon economy, and whether it is appropriate and desirable for the state to establish a global warming pollutant reduction goal; and, if the commission determines that the establishment of a goal is appropriate and desirable, to authorize the commission to develop a recommended goal.
