As sea ice shrinks, Arctic shipping options expand

As sea ice shrinks, Arctic shipping options expand

On October 7, 2013, the Nordic Orion bulk carrier ship completed its journey from Vancouver, Canada, to Pori, Finland, having traveled northward around Alaska and through the Northwest Passage. It was the first large commercial freighter ever to make the voyage through these typically ice-covered Arctic waters. Avoiding the longer journey, through the Panama Canal, […] … learn more→

Fossil fuel use pushes Carbon Dioxide emissions into dangerous territory

Fossil fuel use pushes Carbon Dioxide emissions into dangerous territory

Increasing global emissions of carbon dioxide (CO2), a heat-trapping gas, are pushing the world into dangerous territory, closing the window of time to avert the worst consequences of higher temperatures, such as melting ice and rising seas. Since the dawn of the Industrial Revolution, carbon emissions from burning fossil fuels have grown exponentially. Despite wide […] … learn more→

The Energy Game is Rigged: Fossil Fuel Subsidies Topped $620 Billion in 2011

By Emily E. Adams The energy game is rigged in favor of fossil fuels because we omit the environmental and health costs of burning coal, oil, and natural gas from their prices. Subsidies manipulate the game even further. According to conservative estimates from the Global Subsidies Initiative and the International Energy Agency (IEA), governments around […] … learn more→

The great transition, Part I: From fossil fuels to renewable energy

The great transition, Part I: From fossil fuels to renewable energy

The great energy transition from fossil fuels to renewable sources of energy is under way. As fossil fuel prices rise, as oil insecurity deepens, and as concerns about pollution and climate instability cast a shadow over the future of coal, a new world energy economy is emerging. The old energy economy, fueled by oil, coal, […] … learn more→

On Arctic Sea ice melt and coal mine canaries

On Arctic Sea ice melt and coal mine canaries

Despite peak global temperatures in 2005 and 2010 (unprecedented in the instrumental record), a recent sharp plunge in volume of the Arctic Sea ice and a spate of extreme weather events, coal mining, coal exports and carbon emissions continue to grow, overwhelming any mitigation attempted by schemes such as the Australian carbon price. And although […] … learn more→

Researchers challenge study on hydrofracking's gas footprint

Researchers challenge study on hydrofracking’s gas footprint

A Cornell study’s contention that hydraulic fracturing would be worse for climate change than burning coal is being challenged by another study, also by Cornell researchers. In April 2011, Robert Howarth, the David R. Atkinson Professor of Ecology and Evolutionary Biology, and colleagues published a study in Climatic Change Letters concluding that methane leakage from […] … learn more→

Solar energy incentives around the world

Solar energy incentives around the world

Sunlight is an unlimited source of non-polluting energy. Most power plants currently produce electricity with steam turbines. The heat to generate the steam is supplied by the combustion of fossil fuels such as oil, natural gas, or coal. Staggering volumes of carbon dioxide gas are produced through the combustion process. Carbon dioxide is a greenhouse […] … learn more→

Stress causes clogs in coffee and coal

Stress causes clogs in coffee and coal

It’s easy to get in a jam. But it’s much harder to explain exactly how or when it started. Scientists still aren’t sure what causes clogs in flowing macroscopic particles, like corn, coffee beans and coal chunks. But new experiments by Duke physicist Robert Behringer and his colleagues suggest that when particles undergo a force […] … learn more→

U.S. Carbon emissions down 7 percent in four years: Even bigger drops are coming

U.S. Carbon emissions down 7 percent in four years: Even bigger drops are coming

Between 2007 and 2011, carbon emissions from coal use in the United States dropped 10 percent. During the same period, emissions from oil use dropped 11 percent. In contrast, carbon emissions from natural gas use increased by 6 percent. The net effect of these trends was that U.S. carbon emissions dropped 7 percent in four […] … learn more→
