Guidelines Issued for Diesel Fuel Used in Hydraulic Fracturing

The U.S. Environmental Protection Agency (EPA) issued guidelines on the use of diesel fuel in oil and gas hydraulic fracturing, or fracking, a method that involves pumping water containing chemicals into shale formations to unlock trapped energy resources. The EPA defines five substances as diesel variations and outlines guidelines and “technical recommendations” for their use.…

Keystone XL Assessment Report Finds No Significant Environmental Objections

The State Department issued its final environmental impact statement on the Keystone XL pipeline, which echoed findings in previous analyses that the pipeline would lead to no substantial increase in greenhouse gas emissions. It found that approximately 147-168 million metric tons of carbon dioxide would be created by producing, refining and burning the pipeline’s oil. The report’s release kicks off a 30-day…

Corridors to Survival: Charting a Path to Combat Climate Change in the Tropics

New findings from Woods Hole Research Center scientists use satellite data to recommend habitat corridors between protected areas in the tropics to promote long-term conservation. The concept of habitat corridors in conservation has been around for a while. It’s a topic at global climate talks and an issue for NGOs eager to create pathways for…

Obama Promises Strong Action on Climate Change, Energy Independence in State of the Union Address

In his 2014 State of the Union Address, President Barack Obama took just 5 minutes of the 65-minute speech to cover energy and environment issues. He declared climate change “a fact,” stating “when our children’s children look us in the eye and ask if we did all we could to leave them a safer, more stable world, with…

Obama Doesn’t Need Congress to Move Forward on Clean Energy

A week before President Barack Obama’s State of the Union address, a new report says Obama could advance key measures of his Climate Action Plan with or without the cooperation of Congress. “When they believed a national situation warranted action, some past presidents interpreted their authority broadly and exercised it aggressively,” the report said. “That is the practice of presidential authority Americans…

Study Says United States Tops List of Global Warming Offenders

A new study by Canadian researchers finds the United States, Germany, the United Kingdom, China, Russia, and developing nations Brazil and India were responsible for more than 60 percent of global temperature changes between 1906 and 2005. The U.S. alone was responsible for 22 percent of the warning; China followed at 9 percent and Russia at 8 percent. Brazil…

Carbon Markets Show Glimmers of Recovery in 2014

A year after the launch of its cap-and-trade program, California formally linked its emissions trading scheme with Quebec’s—enabling carbon allowances and offset credits to be exchanged between participants in the two jurisdictions. The linkage, which marks the first agreement in North America that allows for the trading of greenhouse gas emissions across borders, is designed to escalate…

EIA Releases Early Predictions from Annual Energy Outlook

The Energy Information Administration (EIA) on Monday released a 20-page preview of its Annual Energy Outlook 2014, which includes projections of U.S. energy supply, demand and prices through 2040. Although the full report won’t be released until spring 2014, the preview projects a spike of 800,000 barrels a day in domestic crude oil production in 2014. By 2016,…

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…

Report Warns of Sudden Climate Change Impacts

Hard-to-predict sudden changes to Earth’s environment are more worrisome than larger but more gradual impacts of climate change, according a panel of scientists advising the federal government. A 200-page report released Tuesday by the National Academy of Sciences repeatedly warns of potential climate “tipping points” beyond which “major and rapid changes occur.” And some of these changes—happening in years…

Scenes from the Philippines: Post-earthquake, Post-typhoon

Guest blog by Dr. Amanda Vincent, Director and Co-founder of Project Seahorse  It’s been an incredibly difficult few weeks for the central Philippines. Following a 7.2 magnitude earthquake last month that caused considerable loss of lives and homes, the Visayas region was hit on Nov. 7th by Typhoon Haiyan (a.k.a. Yolanda), one of the very strongest…

EPA Proposes Lower Biofuel Mandate

The U.S. Environmental Protection Agency (EPA) on Friday announced cuts to a federal mandate dictating how much ethanol must be blended into gasoline. The mandate—under the Renewable Fuel Standard—would have been scheduled to reach 18.15 billion gallons in 2014, up from 16.55 billion gallons this year. The EPA instead proposes to set the 2014 requirement at 15.21 billion gallons, equal…

U.N. Climate Conference Kicks Off Amid Reminders of Deal Urgency

The 12-day United Nations Climate Change Conference, which aims to forge an agreement to cut climate-altering greenhouse gas emissions, began in Warsaw, Poland, this week. The goal set by the U.N.: limit warming to 2 degrees Celsius over pre-industrial levels. Representatives from nearly 200 countries are debating an agreement that would take effect by 2020. Major breakthroughs are not expected at…

Report: Current Efforts to Slow Global Warming Not Sufficient

Days before world leaders meet in Warsaw, Poland, for the latest United Nations Climate Change Conference, a new report warns that the opportunity to limit global temperature increases to 2 degrees Celsius compared with preindustrial levels is diminishing. The “Emissions Gap Report 2013,” compiled yearly by the United Nations Environment Programme (UNEP), looks at how each nation is meeting its…

Hardened Alpinists Don’t Complain

Science and exploration are companion expressions of human curiosity- and both render a tough breed.
