Climate extremes : recent trends with implications for national security

Climate extremes : recent trends with implications for national security / Michael McElroy & D. James Baker. Harvard University, October 2012, 138 p.

Preface :

The extent and pace of climate changes will lead to potential impacts on food, water, energy and economic security. Observed change in the climate system is an issue of ongoing concern for the US. Recent unusual extreme weather phenomena worldwide, such as droughts, floods, severe storms, and heat waves raise the specter of significant impacts of changing climate in the near term. The authors sought to consider what one could expect in the period of the next decade – would these anomalous climate extremes persist? To what extent are the extreme conditions a result of natural variability or greenhouse warming, and what are plausible impacts on U.S. national security interests? The authors conclude that the early ramifications of climate extremes resulting from climate change are already upon us and will likely continue to be felt over the next decade – affecting human security and impacting U.S. national security interests.

• Weather warning: Study examines climate change as a national security issue / Peter Reuell. Physorg, 20/02/2013

A new report co-authored by Michael McElroy, the Gilbert Butler Professor of Environmental Studies, and D. James Baker, a former administrator of the National Oceanic and Atmospheric Administration, connects global climate change, extreme weather, and national security. During the next decade, the report concludes, climate change could have wide-reaching effects on everything from food, water, and energy supplies to critical infrastructure and economic security…

• A New Harvard Report Probes Security Risks of Extreme Weather and Climate Change. (A new from Harvard University Center for the Environment)

Changes in extremes include more record high temperatures; fewer but stronger tropical cyclones; wider areas of drought and increases in precipitation; increased climate variability; Arctic warming and attendant impacts; and continued sea level rise as greenhouse warming continues and even accelerates. These changes will affect water and food availability, energy decisions, the design of critical infrastructure, use of the global commons such as the oceans and the Arctic region, and critical ecosystem resources…
