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 … more

Global Change and the Earth System: A planet under pressure

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… more

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… more

Public Health Service Act

Description: The Safe Drinking Water Act (SDWA) was established to protect the quality of drinking water in the U.S. This law focuses on all waters actually or potentially designed for drinking use, whether from above ground or underground sources. The Act authorizes EPA to establish minimum standards to protect tap water and requires all owners or operators of public water systems to comply with these primary (health-related) standards. The 1996 amendments to SDWA require that EPA consider a detailed risk… more

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.

Thresholds of Climate Change in Ecosystems

Description: This Report (SAP 4.2) focuses on the thresholds of Climate Change in Ecosystems. As defined in this Synthesis and Assessment Report, 'an ecological threshold is the point at which there is an abrupt change in an ecosystem quality, property, or phenomenon, or where small changes in one or more external conditions produce large and persistent responses in an ecosystem'.Ecological thresholds occur when external factors, positive feedbacks, or nonlinear instabilities in a system cause changes to pr… more
