Reflecting Sunlight to Cool Earth: The NAS Weighs Controversial Measures in New Report

The president’s science advisor John P. Holdren has often observed that humanity has three basic options for dealing with climate change: Mitigation (reducing heat-trapping emissions), adaptation (coping with unavoidable impacts of climate change), and suffering.  The more swiftly we both mitigate and adapt, the less suffering we endure and impose on future generations.

Suppose, however, that we falter and temperatures continue to rise to dangerous levels. In a climate emergency, facing high risks of major and otherwise unavoidable impacts, should the U.S. or other governments consider forced cooling of Earth by injecting reflecting aerosol particles into the stratosphere?

Detective or Scientist? Fingerprinting the Ocean to Estimate Global Sea Level Rise

Guest Bogger

Carling Hay, Ph.D.
Postdoctoral fellow, Harvard University & Rutgers University

Cambridge, MA

When you pick up the newspaper or turn on the television, you are likely to find a story about climate change and rising sea levels. Most of these stories focus on making predictions for the next century and beyond. After all, don’t we already have a complete understanding of the past? The answer to that question isn’t quite so simple.   Read More

Preparing for Climate Change: President’s Budget Misses Opportunity

Yeah, I get it. The president’s budget doesn’t really mean anything. It’s just a vehicle to lay out his vision for the country, right? Congress is controlled by Republicans, and most of the president’s fiscal priorities likely won’t be reflected in the budget he finds on his desk several months from now. But here’s one fiscal priority both parties should be able to support: pre-disaster mitigation, or …disaster preparedness. Read More

How Oregon Can Fill Up On Clean Fuels

Something big is brewing in Oregon. No, it’s not a new IPA from Portland-based Bridgeport Brewery—though that sounds delightful. It’s the next phase of Oregon’s Clean Fuel Program, a forward-thinking regulation that requires transportation fuel to get steadily cleaner on average, ultimately achieving a 10 percent reduction in carbon emissions per unit of fuel in 10 years. Extending this rule is a big deal because approximately one-third of Oregon’s greenhouse gases come from transportation, and Oregon has the in-state resource potential to produce significant amounts of clean fuels.

The Land Sector Can Close Half the Dangerous Climate Change Gap

Today we’re releasing an important report on what the world’s largest emitters of greenhouse gases could do to reduce the global warming pollution released by their land sectors—that is, their agriculture and forests. It’s called Halfway There? What the Land Sector Can Contribute to Closing the Emissions Gap.

President Obama, India’s Prime Minister Modi, and the Opportunity to Cooperate on Climate Change

When I was growing up in New Delhi, the annual Republic Day celebrations were always cause for great national pride. They commemorate the day this large, vibrant democracy’s constitution came into force, after India secured its independence from British colonial rule. This year President Obama will be a special guest for the Republic Day parade, a spectacular display of India’s rich cultural heritage and military might. What I am keenly interested to hear are the ways in which Prime Minister Modi and President Obama plan to cooperate to address one of the biggest challenges facing the world today: climate change.

We Need Sharper Questions for a Broken Climate Debate

Sen. Marco Rubio (R-Florida) recently claimed that human-caused climate change “is not well-established.”

House Speaker John Boehner (R-Ohio) said he wanted to “let scientists debate…” why the climate is changing.

By contrast, Mitt Romney reportedly said “that while he hopes the skeptics about global climate change are right, he believes it’s real and a major problem,” according to the Des Moines Register. Read More
