Definitions and Methodological Options to Inventory Emissions from Direct Human-induced Degradation of Forests and Devegetation of Other Vegetation Types

Description: This report on Definitions and Methodological Options to Inventory Emissions from Direct Human-Induced Degradation of Forests and Devegetation of Other Vegetation Types is the response from the Intergovernmental Panel on Climate Change (IPCC)1 to an invitation from the United Nations Framework Convention on Climate Change (UNFCCC)2 . The report was prepared in cooperation with the preparation of the other report under the IPCC National Greenhouse Gas Inventories Programme (IPCC-NGGIP), on Good Practice Guidance for Land Use, Land-Use Change and Forestry (GPG-LULUCF). The report discusses: Alternative definitions and provides possible framework definitions for countries to consider; Methodological options to inventory emissions from degradation and devegetation activities; Approaches to reporting and documentation; and Implications of methodological and definitional options for accounting under the provisions of Article 3.4 of the Kyoto Protocol (including issues of scale, costs and accuracy).

Revised Research Plan for the U.S. Climate Change Science Program

Description: This Revised Research Plan is an update to the 2003 Strategic Plan of the US Climate Change Science Program (CCSP), a document that was developed via a thorough, open and transparent multi-year process involving a wide range of scientists and managers. The Strategic Plan has long-term value to CCSP, but like any strategic plan, it must be supplemented by shorter-term revisions that take into account both advances in the science and changes in societal needs, and CCSP has an ongoing long-range strategic planning process to ensure that these needs are met. The Revised Research Plan (hereinafter referred to as the Research Plan) draws on CCSP's long-range planning process and provides this update, in compliance with the terms of the Global Change Research Act (GCRA) of 1990. In the Research Plan, the reader will find several things: 1) an updated statement of vision, goals and capabilities consistent with CCSP's current Strategic Plan but reflecting both scientific progress and the evolution of the Program based on accomplishments and evolving societal and environmental needs; 2) a description of the relationship of the Research Plan to the current Scientific Assessment; 3) highlights of ways in which the program is evolving in the context of the progress made over the years 2003-2007 since the Strategic Plan was put in place, and a description of the priorities that have emerged as a result; 4) a description of research plans for the coming years, in order to build upon the work envisioned in the Strategic Plan and begun over the past four years.

Clouds in the Balance

Description: This feature article provides a summary of study about the role of clouds in the balance. Until recently, scientists were uncertain whether clouds had an overall net cooling or heating effect on the Earth's climate. But recent studies show that, in the tropics, a "near cancellation" between shortwave cooling and longwave warming exists, which indicates that the amount of incoming radiant energy is roughly equal to the amount of outgoing radiation. However, small changes in tropical cloudiness can disrupt this precarious balance.

Federal Register Volume 62, No. 78, Pages 19884 to 19887, April 23, 1997

Description: The United States Federal Register is the official daily publication for rules, proposed rules, and notices of Federal agencies and organizations, as well as executive orders and other presidential documents. This specific Executive Order (E.O.) 13045 - Protection of Children from Environmental Health Risks and Safety Risks - was issued by President William J. Clinton in 1997. The order applies to economically significant rules under E.O. 12866 that concern an environmental health or safety risk that EPA has reason to believe may disproportionately affect children. Environmental health risks or safety risks refer to risks to health or to safety that are attributable to products or substances that the child is likely to come in contact with or ingest (such as the air we breathe, the food we eat, the water we drink or use for recreation, the soil we live on, and the products we use or are exposed to). When promulgating a rule of this description, EPA must evaluate the effects of the planned regulation on children and explain why the regulation is preferable to potentially effective and reasonably feasible alternatives.

How Will Climate Change Affect the Mid-Atlantic Region?

Description: Average temperature has risen 1 degree F over the last century in the Mid-Atlantic Region as well as across the globe. Climate science is developing rapidly and many studies project additional warming. Although the future is uncertain and difficult to predict, our best science suggests the following changes are likely. The Mid-Atlantic Region will be somewhat warmer and perhaps wetter, resulting in a wide range of impacts on plants, wildlife, and humans. Human activities that release heat-trapping gases into the atmosphere will continue to accelerate the observed warming trend. Climate change will compound existing stresses from population density and development. The region's overall economy is quite resilient, but impacts will be more severe for some economic activities and localities.

Megadrought and Megadeath in 16th Century Mexico

Description: The native population collapse in 16th century Mexico was a demographic catastrophe with one of the highest death rates in history. Recently developed tree-ring evidence has allowed the levels of precipitation to be reconstructed for north central Mexico, adding to the growing body of epidemiologic evidence and indicating that the 1545 and 1576 epidemics of cocoliztli (Nahuatl for "pest") were indigenous hemorrhagic fevers transmitted by rodent hosts and aggravated by extreme drought conditions.

Ice Core Records of Past Climate Changes: Implications for the Future, USGCRP Seminar, 18 September 1995.

Description: 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 changes.

Signals of Human-induced Climate Warning, USGCRP Seminar, 10 October 1995.

Description: There is increasing evidence that the global climate is changing: global temperatures have risen about 1 F over the past century, mountain glaciers are melting back, sea level is rising. But how is the climate of the United States changing? Are these changes like others being experienced around the world? Is the US climate becoming more or less variable? Are we having more or fewer climatic extremes? This USGCRP seminar addresses these questions in the context of the anthropogenic influences on atmospheric composition and climate

Dust from Africa Leads to Large Toxic Algae Blooms in Gulf of Mexico, Study Finds. [Press release].

Description: This press release summarizes the findings of a new study. Saharan dust clouds travel thousands of miles and fertilize the water off the West Florida coast with iron, which kicks off blooms of toxic algae. The research was partially funded by a NASA grant as part of ECOHAB: Florida (Ecology and Oceanography of Harmful Algal Blooms), a multi-disciplinary research project designed to study harmful algae.
