Opinion about the aptness of the two adjectives…

Supreme Court Reviews EPA’s Power Plant Mercury Rule; Decision Due in June

The U.S. Supreme Court heard oral arguments this week in a challenge to the U.S. Environmental Protection Agency’s (EPA) consideration of cost impacts when developing the Mercury and Air Toxics Standard, (MATS) which are set to go into effect next month. At issue in the case is whether the Clean Air Act requires the EPA…

First Global Review of Arctic Marine Mammals Reveals Uncertain Future

Despite Arctic marine mammals being icons of climate change, little is known about their populations across the Arctic. In a first ever global review of Arctic marine mammals, published last week in Conservation Biology, an international team of scientists provides a circumpolar range assessment. They studied population status and trends for 11 species, including polar bears, ice seals, narwhals,…

McCarthy: States Must Comply with Clean Power Plan

On Tuesday, a lawyer hired by the world’s largest coal mining company told the House Energy and Commerce Subcommittee on Energy and Power that proposed requirements to reduce carbon dioxide emissions from power plants are reckless, and Senate majority leader Mitch McConnell of Kentucky, in an op-ed, said states should ignore them, but U.S. Environmental…

Warming Lakes: New Global Database Sets the Stage for Research on the Ecological Effects of Climate Change

Global assessments based on satellite data have found that the world’s largest lakes have steadily warmed in the last 25 years, and some lakes are warming more rapidly than air temperature. I wrote about this in an earlier post, noting that studies of individual lakes, using temperature data gathered in the traditional way, confirmed these…

Lessons from São Paulo’s Water Shortage

It’s getting harder and harder to separate nature’s role in disasters from our own, and the dire water predicament confronting São Paulo, Brazil, is no exception. But as with the ongoing drought in California, there are important lessons from São Paulo’s grim situation that can help us prepare for the “new normal” that’s unfolding. It’s…

Climate Pledges May Not Be Enough

The European Union (EU) is now the second body to submit an official climate target to the United Nations ahead of talks to reach a global climate agreement in Paris later this year. One of the world’s top emitters, the EU intends to reduce its emissions 40 percent (relative to 1990 levels) by 2030. This…

First-Ever Direct Observation of Greenhouse Gas Increase

A new study in the journal Nature offers that for the first time scientists have directly observed an increase in one major greenhouse gas at Earth’s surface. “We see, for the first time in the field, the amplification of the greenhouse effect because there’s more CO2 [carbon dioxide] in the atmosphere to absorb what the…

First Rules for Arctic Drilling Released

The U.S. Department of the Interior unveiled the first draft rules for offshore oil and gas exploration in the Arctic. The rules would require energy companies to clear a number of safety hurdles before being approved for drilling. “The Arctic has substantial oil and gas potential, and the U.S. has a longstanding interest in the…

McCarthy: Clean Power Plan Targets May Change

The EPA Administrator this week, suggested (subscription) that interim goals for existing power plants to comply with the agency’s proposed Clean Power Plan could be softened before the rule is finalized this summer. The proposal unveiled last year calls for a 30 percent reduction in carbon emissions from 2005 levels by 2030 and sets state-by-state…

Climate Change Poses Existential Water Risks

We often hear it said that climate change is too abstract to win the support needed to effectively combat it. But the primary way we will experience climate change is through the water cycle – through droughts, floods, depleted rivers, shrinking reservoirs, dried-out soils, melting glaciers, loss of snowpack and overall shortages of water to…

Next Stop on Road to a Climate Agreement in Paris: Geneva

Obama Addresses Climate Change with Proposed 2016 Budget

In an effort to increase energy security and resilience to climate change, President Obama’s fiscal 2016 budget proposes a 7 percent increase in funding for clean energy and a new $4 billion Clean Power State Initiative Fund aimed at encouraging U.S. states to make faster and deeper cuts in power plant emissions. The proposed $4…

U.S.-India Climate Agreement Less Substantive Than U.S.-China Climate Deal

The U.S.-India climate agreement announced January 25 creates a new agreement between the second- and third-largest emitters of greenhouse gases in the world but does not have the strength of the U.S.-China climate deal reached last year. Rather than committing India to cap its emissions, the U.S.-India deal called for “enhancing bilateral climate change cooperation”…
