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.

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 …

Scientific news article about Snowball Earth eras. These are times when ice periodically covered the globe, and the era called the Cambrian Explosion, which produced the first fossils of almost all major categories of animals living today.

This paper takes as its initial premise the assumption that there are important and significant populations in the world's drylands who, given the right conditions and incentives, can achieve good livelihoods, accumulate assets to reduce vulnerability and escape from poverty. However, to make a convincing case it is necessary to challenge current wisdom on the distribution and condition of drylands populations, and build more realistic scenarios that decision makers can take seriously. This is a major task, and this paper will only set the challenge and introduce some of the new evidence that is required.

President. global warming later on. Indeed, had such demand-side efforts been underway sooner our current predicaments could have been avoided or lessened. Globally.. Today, the United States produces less than 12 percent of global oil supplies. Even with strenuous efforts by the Bush Administration.

This treaty allows organizations that are not governments of states to join the Inter-American Tropical Tuna Convention, and be subject to its conservation and management protocols.

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.

Different speakers addressed the Panel, and some highlighted the importance of sound data for monitoring and predicting the climate system and noted with concern the decline in observational networks. Others emphasized the value of the scientific information provided by the IPCC for the Convention process and highlighted the need to integrate scientific assessments in sustainable development consideration and to communicate with a wider audience.

This report presents two series of studies performed before COP-6 and COP-6bis, in order to provide DG Environment with economic analysis of the issues at stake in international climate negotiations. These analysis used the background information provided by the large scale world energy partial equilibrium model POLES. They were also based on an extensive use of the Marginal Abatement Cost Curves produced by the POLES model through the ASPEN-sd software, specifically designed to produce assessment.

This brief news article provides preliminary evidence that global warming may have sped up the pace at which grasslands are being overtaken by mesquite, creosote and other shrubs at desert sites around the world.

The UNEP annual report provides an overview of UNEP's activities for the year of 2000. The report also reflects on the possible challenges that the new millennium "the Environment Millennium" may bring.

This document calls for major improvements to the United States transportation infrastructure. The vision includes improvements in energy independence, environmental compatibility, safety, cost, and performance.

For African countries, it is imperative to increase capacity for implementing both the Climate Convention and the Kyoto Protocol, in view of the continent’s vulnerability to the adverse impacts of climate change, including the threat to food security and sustainable development. The country surveys, which are framed around the list of perceived capacity building needs annexed to Decision 10/CP.5, provided insight into the capacity building needs of the project-countries. Hence, the aspects examined during the assessment exercise reflect some of the concerns of African countries; and the stakeholders’ responses can be taken as indications of the capacity building needs of the African countries assessed.
