Tallahassee, We Have a Problem: The Harm Done by Florida’s Climate Leadership Void

What could justify the Governor of Florida, a state widely considered “ground-zero” for climate change in the U.S., to prohibit the use of that term by state staff? Read More

Can Republican Politicians Change Their Tune on Climate and Energy?

When former Texas Governor Rick Perry (R) ran for president in 2011, he flatly rejected climate science and even claimed that scientists had manipulated climate data. But last week, in response to a question about climate and energy issues at the Conservative Political Action Conference, he touted his environmental record, instead. Read More

Days of Haze: How Palm Oil and Landscape Fires Affect Health in Southeast Asia

On a recent trip to Singapore, after the day’s discussion about how best to stop deforestation in Southeast Asia had ceased and the jet-lag was just beginning to take a hold of me, I hopped into bed to fall asleep. Or probably more accurately, I collapsed into bed. I turned on the television and what I saw on the screen was surprising. Read More

Smothering Snow, Spiking Sea Levels, and Other Climate Plot Twists: Expecting the Unexpected in the Northeast

When I first started digging into climate impacts, I used to think that the northeastern U.S., where I live, was a pretty good place to have landed. I still think so. It’s unlikely we’ll see historic mega-droughts, like those forecast by some for the U.S. Southwest. We’ll see heat that we’re far from prepared for, but it’ll be hotter still in the South. Our forests are expected to change, but they’re not under pressure like those in the Mountain West, nor are they currently experiencing rising risks of wildfire. We have our own problems, to be sure, like coastal vulnerability and trends in extreme precipitation.

But this week in the news there are two new studies that reminded me to expect the unexpected. While we understand the general pathway of change, the shorter-term directions the climate can take along the way can take us by surprise. Read More

Rep. Grijalva’s Requests and the Real Problem with Conflict of Interest Disclosure

On Tuesday, Arizona’s U.S. representative Raul Grijalva asked seven academics for their sources of funding and earlier drafts of testimony they have delivered before congressional committees. Since then, many have debated whether the requests cross the line into harassment or witch hunts or McCarthyism. Lost in the discussion around whether the requests are too broad is a bigger question to address: Why don’t we already know who funds the work of those who testify before Congress? Read More

Counting the Benefits of Agroecology: We Have the Tools, Let’s Use Them

With global challenges such as diminishing environmental quality and public health, combined with accelerating climate change, we need more than ever to know how to confront many problems at once. Since plants inhale carbon dioxide and soils store carbon, there are numerous reasons to expect agriculture to play a significant role for improving the human prospect. Indeed, scientific research documents that we have tools to achieve ecological and climatic sustainability, but here’s the catch—we have to use them. Read More

Is Small Farmers’ Firewood Use Burning up the Forests?

For many years, small farmers in developing countries have been blamed for deforestation because of the way that they make breakfast. While in developed countries nearly everyone cooks with fossil fuels, or with electricity generated by fossil fuels or hydroelectricity, in developing countries firewood still predominates, especially among the poorest people in rural areas. But is this really an important driver of deforestation—and thus a major contributor to global warming? A new study—the most in-depth and comprehensive look at the subject yet—says no.

5 Reasons Why Colorado Should Increase—Not Roll Back—Its Renewable Energy Standard

UPDATE: (March 3, 11 a.m.): Good news! Yesterday, the Colorado House of Representative’s State, Veterans, and Military Affairs Committee voted against the proposed rollback of the state’s renewable energy standard, effectively killing SB 44 for the 2015 legislative session. This is yet another defeat for fossil fuel interests who do not want to compete with renewables on a more level playing field.

On February 5th, state Senate Republicans passed a bill to roll back Colorado’s renewable energy standard (RES), which has helped make the state a national leader in clean energy. Rolling back the RES is precisely the wrong direction for Colorado to go at this time. In addition to providing important benefits to Colorado’s economy, increasing renewable energy use is one of the most cost-effective strategies for complying with the EPA’s proposed power plant carbon standards.

Stormy Seas, Rising Risks: New Analysis Shows Undisclosed Climate Change Impacts at Oil Refineries

Ten miles outside New Orleans stands a two-million barrels per day oil refinery, surrounded by the Meraux, Louisiana community. On low-lying ground along the Gulf coast, an elaborate network of pipes and smoke stacks looms beyond double-wide trailers, rows of single-family homes, and a playground. By 2050, the refinery and surrounding areas could be underwater, given intermediate sea level rise estimates. But this won’t be the first time the refinery has seen high water levels. Read More

What Kinds of Scrutiny of Scientists are Legitimate?

This morning, Rep. Raul Grijalva sent letters to seven universities seeking documents related to academics who have testified before Congress on climate change. The requests come in the wake of revelations over the weekend that the Smithsonian Institution agreed not to disclose payments from the Southern Company, a major utility, to fund and review the work of Smithsonian aerospace engineer Willie Soon. As all of the researchers in question have been critical of mainstream climate science, some are wondering if Rep. Grijalva’s requests can be considered a witch hunt. So is it? Read More
