World Sees Some Tangible Outcomes from U.N. Climate Summit

World leaders gathered in New York this week for the United Nations Climate Summit, a meeting aimed at raising carbon reduction ambitions and mobilizing progress toward a global climate deal. In speeches at the summit, President Obama and other leaders recognized that countries across the world are feeling climate change effects, particularly extreme weather. “In America,…

Solar Storm Heading for Earth May Spark Auroras This Weekend

A solar outburst promises weekend northern lights.

Scenes From Mongolia’s Changing Steppe

National Geographic Grantee Hannah Reyes is a photojournalist curious about cultures in transition—how old traditions are surviving, what remains under broader social pressure, and the new forms emerging through the fusion, interaction and conflict of cultures. Mongolian herders are one such culture.

Report, Initiatives Aim to Take Action on Climate Change

Editor’s Note: While Tim Profeta is on vacation, Jeremy Tarr, policy associate in the Climate and Energy Program at Duke’s Nicholas Institute for Environmental Policy Solutions, will author The Climate Post. Tim will post again August 28. A new report from the White House Council of Economic Advisers finds that for each decade of delay, policy actions on climate…

White House Announces New Climate Change Initiatives

The White House on Wednesday announced executive actions to help states and communities build their resilience to more intense storms, high heat, sea level rise, and other effects of climate change. The actions, which involve several federal agencies, were among the recommendations by the president’s State, Local and Tribal Leaders Task Force on Climate Preparedness and Resilience. “…Climate…

Senate Clears Way for Keystone XL Pipeline

The U.S. Senate Energy and Natural Resources Committee voted 12 to 10 on a bill Wednesday approving the long-debated Keystone XL oil pipeline. The pipeline, which would transport oil from Canada to the U.S. Gulf Coast, requires presidential approval as it crosses international boundaries. Without a commitment from Senate Majority Leader Harry Reid to bring it to a vote…

EPA Releases Proposed Rule for Existing Power Plants

The U.S. Environmental Protection Agency (EPA) this week announced a proposed rule to reduce carbon dioxide emissions from existing fossil fuel–fired power plants 30 percent below 2005 levels by 2030. This first-of-its-kind proposal uses an infrequently exercised provision of the Clean Air Act to set state-specific reduction targets for carbon dioxide and to allow states to devise individual or…

Watch: Sun Unleashes First Big Flare of 2014, May Create Colorful Aurora Light Show

The new year has started off with a bang, with a powerful solar flare being hurled off the surface of the sun on Tuesday. NASA’s Solar Dynamics Observatory and STEREO spacecrafts managed to capture the eruption of a massive X-class flare—the largest type on the Richter scale of solar explosions—as it occurred above a group of sunspots directly…

Clean Air Rules Face Scrutiny as World’s Largest Emitter Develops Climate Plan

Oral arguments were held Tuesday to determine the legality of a rule that regulates air pollution crossing state lines. Before the U.S. Supreme Court was the issue of whether the U.S. Environmental Protection Agency (EPA) exceeded its authority by designing state limits for air pollution when it developed the Cross-State Air Pollution Rule (CSAPR), which was intended to take…

Sun About To Magnetically Flip

As the sun reaches a crescendo in its 11 year activity cycle this year, it’s also getting ready to go topsy-turvy.  The sun’s global magnetic field is about to reverse—flipping its orientation so that north becomes south and south becomes north. Astronomers estimate that we may be only three or four months away from this mysterious…

U.N. Climate Talks Pick Back Up in Bonn

The next round of U.N. climate change talks began in Bonn, Germany—the final round of midyear negotiations before the 19th Conference of the Parties to the U.N. Framework Convention on Climate Change in November. The talks are, in part, focused on defining elements of a universal climate agreement by 2015, an agreement that would be enforced by 2020.…

Looming Sequester Has Implications for National Weather Forecasting, Energy

Unless Congress reaches a deal by Friday, a set of automatic spending cuts—known as the sequester—will take effect. According to the Obama Administration, this trigger, for $85 billion worth of across-the-board federal spending cuts, is expected to have significant implications for climate and energy. Newly released estimates by the White House detail how the cuts are projected to impact programs in each state. Decreases in environmental…

A Wind Tax Credit, Indefinitely?

In last week’s State of the Union address, President Barack Obama called for doubling research and development funding for renewable energy. A policy document released by the White House following the State of the Union proposes making the wind production tax credit—which was renewed in January for one year as part of the deal to avert the fiscal cliff—permanent. “To once…

Federal Court Tosses EPA’s ‘Good Neighbor’ Pollution Rule

The U.S. Court of Appeals for the D.C. Circuit this week threw out the Cross-State Air Pollution Rule (CSAPR), which set stricter limits on sulfur dioxide and nitrogen oxide emissions from coal-burning power plants in 28 states and the District of Columbia. In a 2–1 ruling, the panel held the U.S. Environmental Protection Agency (EPA) exceeded its authority under the…

Harnessing Sun, Wave Power for Energy

Oceans, which cover more than two-thirds of the planet, hold a large amount of energy. In fact, the U.S. Department of Energy estimates ocean wave and tidal currents have the potential to account for 15 percent of the nation’s electricity by 2030. While technologies harnessing energy from tides and currents have been domestically discussed for decades, the…
