The Northern Eurasia Earth Science Partnership: An Example of Science Applied to Societal Needs

Little is known about the biogeochemical, energy, and water cycles of the Northern Eurasian landmass, a carbon-rich region capable of significantly influencing global climate. In response to this deficiency, the Northern Eurasian Earth Science Partnership Initiative (NEESPI) was formed in 2004 to better understand and quantify feedbacks between Northern Eurasia and the global climate. This partn... View arrow

Northern Eurasia and the Global Earth System

In August 2007, a meeting was held at the Aspen Global Change Institute that addressed the role of the Northern Eurasian Landmass in the global Earth system. The meeting brought together members of the Northern Eurasia Earth Science Partnership Initiative (NEEPSI) to discuss how current and future research efforts in the region can better support global climate projections. One conclusion of the... View arrow

Climate Change and Aspen: An Assessment of Impacts and Potential Responses

As part of the Canary Initiative, AGCI contracted with the City of Aspen in May 2005 to author a study to determine the likely consequences of global warming on the City of Aspen. The results of study are detailed in this installment of AGCI's ongoing Elements of Change series. The report focuses on three major areas: 1. Changing climate trends and projections in Aspen and the surrounding are... View arrow

Impacts of Extreme Weather and Climate on Terrestrial Biota

Climate plays a key role in biotic systems, and while it is easy to predict how living systems react to gradual changes in climate, less certainty exists about the effects of extreme weather events. This article presents research showing specific examples of how extreme weather events have brought about manifest changes to species populations, behavior, morphology, as well as ecosystem-level effe...

CLIMATE POLICY (2003)

The Climate Impacts of Land Surface Change and Carbon Management, and the Implications for Climate-Change Mitigation Policy

While carbon sequestration in the terrestrial biosphere may play a necessary role in mitigating anthropogenic climate change, current climate mitigation policies do not generally take into account the effects of the resulting changes in land surface albedo, the fluxes of sensible and latent heat to the atmosphere, and the distribution of energy within the climate system. As a result, proposed mit... View arrow

AGCI ELEMENTS OF CHANGE REPORT (1998)

Climate Extremes: Changes, Impacts and Projections

Although the relationship between climate change and extreme weather events, such as hurricanes and floods, is still uncertain, many scientists believe the two to be linked. This report focuses on the methods and evidence surrounding such a link. It presents existing data that suggests an upward trend in extreme weather and discusses how existing climate models can be reinterpreted or improved t... View arrow

Scaling from Site-Specific Oservations to Global Model Grids

Much attention in climate modeling has focused on how to downscale from large scale model output to smaller scales in order to resolve critical features such as mountain ranges. This Elements of Change report looks at the other side of the scale problem. It addresses the problem of known as upcaling, which is scaling from areas measured in square meters to larger aggregates. In this report are d... View arrow

Planning for the U.S. National Assessment of the Consequences of Climate Change

The U.S. Global Change Research Program Act of 1990 requires the U.S. government to do periodic climate impact assessments of the United States. This Elements of Change report serves as a guide to help outline the content and approach taken for this important assessment. The content of this report reflects the discussions that took place at a 1997 AGCI meeting among federal agency representatives,... View arrow

AGCI ELEMENTS OF CHANGE REPORT (1995)

Changes in Global Vegetative Patterns and Their Relationship to Human Activity

Since the onset of satellites, particularly Landsat in 1972, the ability to map vegetative cover type and changes in its aerial extent has led to a fundamentally new way of understanding the Earth and rates of change to its surface. This Elements of Change report explores the technical aspects of remote sensing and analysis of data along with a variety of ground truthing techniques. Furthermore, i... View arrow
