Environmental Effects of Ozone Depletion: 1994 Assessment

Description: A change in the composition of the stratosphere becomes relevant to society only if it has noticeable effects. This places the assessment of effects in a pivotal role in the problem of ozone depletion. Decreases in the quantity of total-column ozone, as now observed in many places, tend to cause increased penetration of solar UV-B radiation (290-315 nm) to the Earth's surface. UV-B radiation is the most energetic component of sunlight reaching the surface. It has profound effects on human health, animals, plants, microorganisms, materials and on air quality. Thus any perturbation which leads to an increase in UV-B radiation demands careful consideration of the possible consequences. This is the topic of the present assessment made by the Panel on Environmental Effects of Ozone Depletion.

Ocean Biogeochemistry and Global Change

Description: From the perspective of terrestrial ecosystems, the most important component of global change over the next three or four decades will likely be land-use/cover change. It is driven largely by the need to feed the expanding human population, expected to increase by almost one billion (109) people per decade for the next three decades at least. Much of this increase will occur in developing countries in the low-latitude regions of the world. To meet the associated food demand, crop yields will need to increase, consistently, by over 2% every year through this period. Despite advances in technology, increasing food production must lead to intensification of agriculture in areas which are already cropped, and conversion of forests and grasslands into cropping systems. Much of the latter will occur in semi-arid regions and on lands which are marginally suitable for cultivation, increasing the risk of soil erosion, accelerated water use, and further land degradation.

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.

Science Plan and Implementation Strategy

Description: The IGAC Science Plan and Implementation Strategy lays out the scientific objectives and key research issues of the atmospheric chemistry project of the International Geosphere Biosphere Programme (IGBP) as both IGAC and IGBP enter their second phase. It also lays out a framework for addressing these objectives and issues, recognizing the need for collaboration with partner programmes and projects. The scientific focus of this document emerged from the first decade of IGAC research, much of which was conducted in the context of focused, intensive measurement campaigns. The scope of IGAC in its next phase includes both regional characterisation and the extension into issues that cross more expansive boundaries in space, time and discipline. While local and regional-scale atmospheric chemical composition will be a primary focus, it is now clear that issues such as intercontinental transport and transformation of chemically active species and the interactions between atmospheric chemistry and climate must also be addressed in order to better understand atmospheric chemical composition and to provide guidance to the public and policy-making community.

Climate Change: State of Knowledge

Description: This brief report describes that the Earth's climate is predicted to change because human activities are altering the chemical composition of the atmosphere. The buildup of greenhouse gases-primarily carbon dioxide, methane, nitrous oxide and chlorofluorocarbons-is changing the radiation balance of the planet. The basic heat-trapping property of these greenhouse gases is essentially undisputed. However, there is considerable scientific uncertainty about exactly how and when the Earth's climate will respond to enhanced greenhouse gases. The direct effects of climate change will include changes in temperature, precipitation, soil moisture, and sea level. Such changes could have adverse effects on ecological systems, human health, and socio-economic sectors.

Ozone

Description: The amount and distribution of ozone molecules in the stratosphere varies greatly over the globe. Ozone molecules are transported around the stratosphere much as water clouds are transported in the troposphere. Therefore, scientists observing ozone fluctuations over just one spot could not know whether a change in local ozone levels meant an alteration in global ozone levels, or simply a fluctuation in the concentration over that particular spot. Satellites have given scientists the ability to overcome this problem because they provide a picture of what is happening daily over the entire Earth.

Our Changing Planet: The FY 2002 U.S. Global Change Research Program

Description: 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 scientists provide to policy- and decision-makers. Without them, the IPCC SPM [Summary for Policymakers] could give the impression that the science of global warming is 'settled,' even though many uncertainties still remain. The emission scenarios used by the IPCC provide a good example. Human dimensions will almost certainly alter emissions over the next century. Because we cannot predict either the course of human populations, technology, or societal transitions with any clarity, the actual greenhouse gas emissions could either be greater or less than the IPCC scenarios. Without an understanding of the sources and degree of uncertainty, decision makers could fail ...

Carbon Monoxide from California Fires

Description: Large fires can be blamed for some polluted air. In addition to ash and smoke, fires release carbon monoxide into the atmosphere as they burn. This false-color image shows the atmospheric column of carbon monoxide, with yellow and red indicating high levels of pollution. (The gray areas show where no data were taken, likely due to cloud cover.) The data were taken by the Measurements Of Pollution In The Troposphere (MOPITT) instrument aboard NASA's Terra satellite for the period October 26-31, 2003.

Past Global Changes (PAGES) Status Report and Implementation Plan

Description: This document summarizes progress made thus far by the Past Global Changes (PAGES) programme element of the International Geosphere-Biosphere Programme (IGBP). The document also outlines the implementation plans for most of the Foci, Activities and Tasks currently within the PAGES remit. The plan first introduces the scope and rationale of PAGES science and explains how PAGES is organized structurally and scientifically to achieve its goals. For all of the palaeosciences relevant to IGBP goals, PAGES has sought to identify and create the organizational structures needed to support continued work and progress. Models intended to predict future environmental changes must, in order to demonstrate their effectiveness, be capable of accurately reproducing conditions known to have occurred in the past. Through the organization of coordinated national and international scientific efforts, PAGES seeks to obtain and interpret a variety of palaeoclimatic records and to provide the data essential for the validation of predictive climate models. PAGES activities include integration and intercomparison of ice, ocean and terrestrial palaeorecords and encourages the creation of consistent analytical and data-base methodologies across the palaeosciences. PAGES has already played a crucial role in the archiving, management and dissemination of palaeodata. This is fully summarized in the recently published Global Palaeoenvironmental Data Workshop Report (95-2). The growing significance of this type of activity is evidenced by the steep increase in consultation and use of the data currently in the public domain and accessible electronically, and by the growing importance of such data for model validation and intercomparison.
