Strategic Plan for the U.S. Climate Change Science Program

Description: This strategic plan has been prepared by the 13 federal agencies participating in the CCSP, with coordination by the CCSP staff under the leadership of Dr. Richard H. Moss. This strategic plan responds to the President's direction that climate change research activities be accelerated to provide the best possible scientific information to support public discussion and decision-making on climate-related issues.The plan also responds to Section 104 of the Global Change Research Act of 1990, which mandates the development and periodic updating of a long-term national global change research plan coordinated through the National Science and Technology Council.This is the first comprehensive update of a strategic plan for U.S. global change and climate change research since the original plan for the U.S. Global Change Research Program was adopted at the inception of the program in 1989.

Marine Ecosystems and Global Change

Description: The ocean is a vital component of the metabolism of the Earth and plays a key role in global change. In fact, the oceans cover so much of the Earth's surface that our planet has been described as the Water Planet, and it could be argued that its most extensive ecosystems are marine. Marine ecosystems are inextricably involved in the physical, chemical, biological and societal processes of global change. It is impossible to describe and understand the Earth system without understanding the ocean, the special characteristics of the environment that it provides for life, the changes that it is undergoing and the manner in which these changes interact with the total Earth System. Understanding the functioning of marine ecosystems and how they respond to global change is also essential in order to effectively manage global marine living resources, such as fisheries. The GLOBEC project is an international response to the need to understand how global change will affect the abundance, diversity and productivity of marine populations, from zooplankton to fish, that comprise a major component of oceanic ecosystems. GLOBEC's goal is to advance our understanding of the structure and functioning of such ecosystems, their major subsystems, and responses to physical forcing so that a capability can be developed to forecast the response of marine ecosystems to global change. This volume in the IGBP Science Series, "Marine Ecosystems and Global Change", gives topical examples of the scientifi c problems that GLOBEC is tackling, the innovative approaches adopted, and some selected scientific achievements. It has been written at a time when GLOBEC is in the mid-phase of its implementation. The ultimate achievements of GLOBEC research will be presented in a final synthesis at the end of the project.

Environmental Variability and Climate Change

Description: The PAGES research community works toward improving our understanding of the Earth's changing environment. By placing current and future global changes in a long term perspective, they can be assessed relative to natural variability. Since the industrial revolution, the Earth System has become increasingly affected by human activities. Natural and human processes are woven into a complex tapestry of forcings, responses, feedbacks and consequences. Deciphering this complexity is essential as we plan for the future. Paleoenvironmental research is the only way to investigate Earth System processes that operate on timescales longer than the period of instrumental records.

Circumpolar Arctic Vegetation [Map]

Description: The Circumpolar Arctic Vegetation Map shows the types of vegetation that occur across the Arctic, between the ice-covered Arctic Ocean to the north and the northern limit of forests to the south. Environmental and climatic conditions are extreme, with a short growing season and low summer temperatures. As one moves southward (outward from map's center in all directions), the amount of warmth available for plant growth increases considerably.

Effects of Climate Change on Energy Production and Use in the United States

Description: This document, part of the Synthesis and Assessment Products described in the U.S. Climate Change Science Program (CCSP) Strategic Plan. Climate affects the design, construction, safety, operations, and maintenance of transportation infrastructure and systems. The prospect of a changing climate raises critical questions regarding how alterations in temperature, precipitation, storm events, and other aspects of the climate could affect the nation's roads, airports, rail, transit systems, pipelines, ports, and waterways. Phase I of this regional assessment of climate change and its potential impacts on transportation systems addresses these questions for the region of the U.S. central Gulf Coast between Galveston, Texas and Mobile, Alabama. This region contains multimodal transportation infrastructure that is critical to regional and national transportation services. Historical trends and future climate scenarios were used to establish a context for examining the potential effects of climate change on all major transportation modes within the region. Climate changes anticipated during the next 50 to 100 years for the central Gulf Coast include warming temperatures, changes in precipitation patterns, and increased storm intensity. The warming of the oceans and decline of polar ice sheets is expected to accelerate the rate of sea level rise globally. The effects of sea level rise in most central Gulf Coast counties will be exacerbated by the sinking of the land surface, which is accounted for in this assessment. The significance of these climate factors for transportation systems was assessed.

Ozone

Description: In the stratosphere, ozone is created primarily by ultraviolet radiation. When high-energy ultraviolet rays strike ordinary oxygen molecules (O2), they split the molecule into two single oxygen atoms, known as atomic oxygen. A freed oxygen atom then combines with another oxygen molecule to form a molecule of ozone. There is so much oxygen in our atmosphere, that these high-energy ultraviolet rays are completely absorbed in the stratosphere.

IHDP Global Carbon Cycle Research: International Carbon Research Framework

Description: The degree to which carbon flows balance each other - human activities leading to carbon emissions into the atmosphere, vegetation and oceans soaking it up - is the subject of vigorous debate. It is not yet possible to define quantitatively the global effects of human activities such as forestry and agriculture, and may never be so. However, studies to determine these effects have emerged as critical for understanding how the earth's climate will evolve in the future. Global concern about the potential implications of the behaviour of the carbon cycle under anthropogenic stress includes concepts of system instability and large scale change. To contribute to understanding this behaviour, and our potential responses to it, requires a thorough investigation of both biophysical and social systems. Until recently, most scientific assessments of such risks focused on the anatomy of conceivable environmental changes themselves, devoting little attention to either the human driving forces or the ecosystems and societies that might be endangered by the changes. Recently, however, questions about the linkage and interaction of social, ecological, and biogeochemical systems are emerging as a central focus of policy-driven assessments of global environmental risks. The approach used here is to accept humans as an integral part of the carbon cycle, not as an agent perturbing an otherwise natural system - indeed, this approach assumes there is no independence of the different components of the carbon cycle. The human dimensions research community sees this critical and necessary re-conceptualisation as the foundation of a new approach to studying the interaction between human and environmental systems.
