Full Disclosure: Using Transparency to Fight Climate Change

Elena Fagotto, Mary Graham

An essential first step in any effective climate change policy is to require major contributors to fully disclose their greenhouse gas emissions. Congressional leaders are finally working seriously on long term-approaches to counter climate change. But all the major proposals leave a critical policy gap because they would not take effect for at least five […]

The Energy-Climate Complex: Is Climate Change a National Security Issue?

Richard A. Matthew

The case for linking climate change and national security is robust but imperfect, and today there is a serious debate about whether it makes sense. Around the planet there is growing momentum to define climate change as a security issue and hence as an agenda-topping problem that deserves significant attention and resources. In December 2010, […]

Practical Pieces of the Energy Puzzle: Climate Change: Think Globally, Assess Regionally, Act Locally

Charles F. Kennel

Scientists must develop regional assessments of climate change that are essential to the local policymakers who will have to make the critical decisions about how to respond. Climate change is here to stay. No matter how effectively governments and the private sector limit greenhouse gas emissions, average global temperatures will rise during the next several […]

Practical Pieces of the Energy Puzzle: Reduce Greenhouse Gases Profitably

Richard Munson

A regulatory system that rewards energy companies for innovations that boost efficiency can appeal to environmentalists and industry alike. After the Senate’s failed effort to pass the Lieberman-Warner climate change bill, Congress could conclude that reducing greenhouse pollution is a political impossibility—the costs too high, the benefits too uncertain, the opposition too entrenched. But that […]

Perspective: Agriculture’s Role in Cutting Greenhouse Gas Emissions

William J. Parton, Stephen J. Del Grosso, Ernie Marx, Amy L. Swan

Agriculture is responsible for 7% of total emissions of greenhouse gases into the atmosphere in the . Although agriculture is not the major source of greenhouse gas emissions—that title belongs to industrial plants that burn fossil fuel—it is nevertheless an important one and deserves increased attention. The good news is that useful remedies are at […]

Perspective: Global Warming: The Hard Road Ahead

Robert Hahn, Peter Passell

With a president committed to fighting climate change and a new Congress inclined to go along, the prospects for greenhouse gas emissions abatement legislation are bright. That’s good news. The Bush and Clinton administrations’ intransigence on this issue set back U.S. action by at least a decade. But it should not obscure the reality that […]

Perspective: A Course Adjustment for Climate Talks

Ruth Greenspan Bell, Barry Blechman

With little hope that the United Nations Framework Convention on Climate Change (UNFCCC) process will produce an effective treaty, at least for the next several years and perhaps longer, are there other paths that could lead to near-term reductions in greenhouse gas emissions? One approach, forcefully articulated by Richard Benedick (Issues, Winter 2007), would replace […]

The Road to a New Energy System: Climate Change and U.S. Competitiveness

Joel S. Yudken, Andrea M. Bassi

We need to move to a low-carbon, energy-efficient economy, but we also need to be sure that we don’t lose critical manufacturing sectors in the process. The Obama administration and Congress have been grappling with how to craft legislation that addresses the looming threat of global warming while reducing U.S. dependence on foreign energy sources. […]

The Climate Benefits of Better Nitrogen and Phosphorus Management

Alan R. Townsend, Peter M. Vitousek, Benjamin Z. Houlton

Pursuing more efficient use of these elements has clear environmental, socioeconomic, and national security benefits. It would also help reduce some of the risks of a warming climate. Nearly four decades have passed since the phrase “global warming” first appeared in a scientific journal. Writing in Science in 1975, geochemist Wallace Broecker warned that rising […]

Changing Climate, More Damaging Weather

Robert Repetto, Robert Easton

By failing to account for the effects of climate change, long-term projections of extreme weather are providing dangerously inaccurate guidance for critical investments in infrastructure and public safety. The weather varies, but climate change affects the frequencies with which particular weather occurs, including the frequencies of extreme weather, such as heavy storms, heat waves, and […]
