Melting Arctic Sea Ice Causing More Warming Than Expected

February 24, 2014 by Tom Schueneman

Arctic Ice Melt

Scientists have long modeled the expected warming due to the decreased albedo effect as melting Arctic sea ice exposes more open ocean. As early as the 1960′s climate researchers have predicted how this phenomenon will amplify global warming.[read more]

Activism and Deception Underlie Weather Channel's Eagle Ford Shale Report

February 20, 2014 by Steve Everley

A report by InsideClimate News and the Center for Public Integrityconcludes that shale development in south Texas is “releasing a toxic soup of chemicals into the air.” But shaky research underlying the report raises serious questions about the validity of those claims.[read more]

Methane Emissions Far Worse Than US Estimates, But Study Concludes Natural Gas Still Better Than Coal

February 18, 2014 by Marianne Lavelle

Methane Leaks and the Environment

Emissions of the potent heat-trapping gas, methane, the main component of natural gas, are likely 50 percent higher than U.S. government has estimated in its official greenhouse gas inventory, says a new study that is the most comprehensive effort yet to assess the problem.[read more]

Do Methane Leaks Negate Climate Benefits of Natural Gas? Four Takeaways From a New Science Study

February 14, 2014 by Jesse Jenkins

Natural Gas and Methane

A new analysis recently published in Science concludes that more methane is leaking from natural gas wells and pipelines than the federal government has actually estimated, eroding some of the climate benefits of the cleaner-burning fuel.[read more]

Study: Arctic Warming Drives More Extreme Summer Heat Waves, Droughts, And Deluges

Arctic Warming and Weather

A new study has linked the past decade’s exceptional number of unprecedented summer extreme weather events in the United States and Europe with the record declines in both summer Arctic sea ice and snow cover on high-latitude land.[read more]

How Much Methane Is There?

December 3, 2013 by Edward Dodge

Methane Emissions

There has been a lot of talk this week about a new PNAS study which found much higher levels of methane in the atmosphere than previously estimated. My reaction was that this study was one more piece of evidence that there is a lot of methane out there available to be captured and utilized.[read more]

Natural Gas Reality Check: US Methane Emissions May Exceed Estimates By 50 Percent

November 29, 2013 by Marianne Lavelle

A new study challenges our understanding of natural gas as a clean fuel, and raises new questions about the U.S. energy boom. Sure, natural gas (or methane, its main component) burns with less pollution than coal, but release it directly to the atmosphere and it is a highly potent greenhouse gas.[read more]

CO2 and Climate

A new study on continued global warming after emissions stoppage challenges the widely-accepted scientific consensus that the planet’s temperature would actually remain the same or decline if CO2 emissions suddenly stopped.[read more]

Study: No Long-Term Climate Benefit From Shale Gas Revolution

Shale Gas and Climate Change

Claims that shale gas will significantly reduce US carbon emissions are based on hand-waving and wishful thinking. That’s because those claims assume natural gas is replacing coal only, rather than some combination of coal, renewables, nuclear power, and energy efficiency.[read more]

Can Low-Income and Multi-Family Households Benefit From Energy Efficiency?

October 8, 2013 by Katherine Tweed

Low-income households spend about twice the percentage of their income on energy as compared to middle- or upper-class homes. Yet many residential energy-efficiency solutions are tailored only to the biggest homes, neglecting multi-family residences.[read more]

New International Climate Report Has Profound Implications for Latin America

October 5, 2013 by NRDC Switchboard

The new report from the Intergovernmental Panel on Climate confirms what countless people in Latin America and the Caribbean already know – something is seriously wrong with the weather and it’s time we start doing something about it.[read more]

Scientific Impartiality

A recent study found that 99 percent of the greenhouse gas escaping from wells could be captured by state of the art equipment. The study’s findings were celebrated by environmentalists, but immediately criticized by two Cornell University scientists.[read more]

Natural Gas and Fugitive Emissions

The Environmental Defense Fund has spearheaded an ambitious industry-funded series of studies on fugitive emissions from fracking and other natural gas life cycle operations, and the first study to be released looks just like what you’d expect from an industry-funded study.[read more]

Study Of Best Fracked Wells Finds Low Methane Emissions, Skips Super-Emitters

Fracked Wells Study

The good news: A sample of what are probably the best fracked wells in the country finds low emissions of methane, a potent heat-trapping gas. The bad news: The study likely missed the super-emitters, the wells that are responsible for the vast majority of methane leakage.[read more]

Natural Gas Study: Allays Fears for Some, Inspires Hot Air From Others
