Climate change

Description: The Earth's climate has not been constant over geological time. This record is contained in ice, which has built up as snowfall accumulated in distinct yearly layers. Pockets of air trapped between the snow crystals contain traces of past atmospheres, which in turn tell us about the climate at the time the snow formed. Glaciologists collect this record by drilling ice cores and then use sensitive chemical techniques to analyse the layers.

Report on the TCO/GCP Terrestrial Carbon Observations and Model-Data Fusion Workshop

Description: The global carbon cycle is of intense interest to policy-makers, the scientific community, and public organizations. As a result, numerous new programmes and projects have been developed over the last few years. TCO and GCP are two such complementary initiatives which share a common goal of advancing the availability of more accurate and mutually consistent estimates of terrestrial carbon sources, sinks and processes, regionally and globally, through syntheses of observations and models. The workshop was intended to advance the availability of more accurate and mutually consistent estimates of the distribution of carbon sources and sinks at a regional and global level. This goal can be achieved by convergence of in situ and satellite observations, experiments and modelling strategies; improvements in data acquisition and sharing; and product generation, distribution and use. The workshop focused on the following questions and associated issues: 1. What carbon cycle data products could be routinely produced from a carbon observation system based on model-data and model-data fusion? 2. What are the main conceptual approaches to assimilating atmospheric carbon content, terrestrial carbon flux and remotely sensed data into coupled atmospheric circulation-carbon cycle models? 3. What is the present and eventual uncertainty regarding the main carbon fluxes at global and regional scale, and how will it be reduced by projects currently underway and about to begin? 4. In what regions, and on what topics, will new data inputs make the largest contribution to reducing the residual uncertainties? What actions should be taken to overcome the gaps and limitations identified?

Understanding ecosystems

Description: Plants and animals live in environments which change over different periods of time. Some changes happen each year with the seasons, whilst others take hundreds or even millions of years. As these changes occur, living organisms respond in different ways. To cope with the changing seasons, individuals can change their physiology or behaviour, for instance by hibernating or migration. In response to longer-scale change, species may adapt through evolutionary change. If they cannot, they must either move away or become extinct.

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.

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.

Remarks by Administrator O'Keefe at the Earth Observation Summit

Description: Remarks by NASA Administrator Sean O'Keefe at the 2003 Earth Observation Summit in Washington, DC. The purpose of the summit was to promote the development of a comprehensive, coordinated, and sustained Earth observation system or systems among governments and the international community to understand and address global environmental and economic challenges, and also to begin a process to develop a conceptual framework and implementation plan for building this integrated Earth observation system. When the space age dawned it was clear that the ability to propel robotic spacecraft and humans beyond the gravity of our home planet would open up untold avenues of exploration and discovery throughout the Solar System and beyond. What was not understood at the time was how comprehensive observations of the Earth system from space would lead to a significant new field of scientific inquiry.

NOAA Reports Potent Greenhouse Gas Levels Off

Description: This document provides a summary of a study by NOAA researchers and National Institute for Space Research in the Netherlands. According to the study, one of the atmosphere's most potent greenhouse gases, methane, may now have leveled off. Scientists aren't sure yet if this "leveling off" is just a temporary pause in two centuries of increase or a new state of equilibrium.

Global Carbon Project: The Science Framework and Implementation

Description: Carbon cycle research is often carried out in isolation from research on energy systems and normally focuses only on the biophysical patterns and processes of carbon sources and sinks. The Global Carbon Project represents a significant advance beyond the status quo in several important ways. First, the problem is conceptualised from the outset as one involving fully integrated human and natural components; the emphasis is on the carbon-climate-human system (fossil-fuel based energy systems + biophysical carbon cycle + physical climate system) and not simply on the biophysical carbon cycle alone. Secondly, the development of new methodologies for analysing and modelling the integrated carbon cycle is a central feature of the project. Thirdly, the project provides an internally consistent framework for the coordination and integration of the many national and regional carbon cycle research programmes that are being established around the world. Fourthly, the project addresses questions of direct policy relevance, such as the management strategies and sustainable regional development pathways required to achieve stabilisation of carbon dioxide in the atmosphere. Finally, the Global Carbon Project goes beyond the traditional set of stakeholders for a global change research project by seeking to engage the industrial and energy sectors as well as the economic development and resource management sectors in the developing regions of the world.
