Oregon State University researchers this week revealed details about a piece of amber from the Early Cretaceous period that contains a spider in its web attacking an intruding wasp.
The burning of fossil fuels and the release of carbon dioxide into the atmosphere don't affect just the air--it also impacts the Earth's oceans, according to U.S. National Oceanic and Atmospheric Administration (NOAA).
Oceans absorb the carbon dioxide, which in turn changes the water's pH acidity levels. What this means is that coral reefs are growing at a slower rate and the survival of marine species is decreasing, according to NOAA.
Now, the speed at which ocean pH level is changing is faster than any time in the last 300 million years, according to a new … Read more
To measure a country's greenhouse emissions from fossil fuels, it makes sense to consider the whole carbon supply chain, from oil well or coal mine to a consumer's shelf, scientists reported today.
Currently, putting a price on climate-warming carbon dioxide generated by oil, coal, natural gas, and other fossil fuels typically takes place where the fuel is burned.
However, this may not be the most effective way to calculate carbon emissions' cost, the researchers wrote in the journal Proceedings of the National Academy of Sciences.
Carbon dioxide generated by human activities such as coal-fired power plants and factories … Read more
Fossil fuel subsidies worth $312 billion should be realigned to ensure the growth of renewable energy and curb the world's reliance on carbon-intensive fuels, the International Energy Agency said in a report.
Demand for fossil fuels is outstripping the deployment of cleaner technologies. Renewable energy has seen growth rates of 30 percent to 40 percent over recent years but coal has met 47 percent of global new electricity demand over the past decade, the IEA said in its "Clean Energy Progress Report" (PDF) today.
To change this, the IEA suggests realigning fossil fuel subsidies to support clean … Read more
President Barack Obama today proposed boosting funds for clean-energy research and deployment in his 2012 budget by slashing subsidies for fossil fuels such as oil, gas, and coal.
The budget would provide the Department of Energy with $29.5 billion for fiscal year 2012, up 4.2 percent from the proposed 2011 budget, and up 12 percent from the enacted 2010 budget. Some $8 billion would support research in clean energy like wind, solar, and advanced batteries.
"Whomever leads in the global, clean-energy economy will also take the lead in creating high-paying, highly skilled jobs for its people," … Read more
About half of the electricity in the U.S. is made by burning coal, but a limit on carbon emissions from utilities would lead to a shift toward nuclear, natural gas, and renewable energy, according to a report.
Research and consulting company ICF International released one of its periodic Energy Outlook reports last week, projecting a change in the fuel used for generating electricity in the U.S. if Congress passes an energy and climate bill.
Though some moviegoers' powerful identification with "Avatar" may have inspired them to ponder the planet and rethink their carbon footprint, they likely missed the irony: millions of nonbiodegradable, plastic 3D glasses were reportedly distributed for the movie.
Luckily, cinemas may be on their way to adopting a more sustainable technology. Cereplast, an L.A.-based maker of bioplastics, has partnered with Oculus3D to create what appear to be the first biodegradable 3D glasses. Unlike current 3D glasses that are made using petroleum-based plastic, these will be manufactured with plastic derived from plant materials.
Cereplast and Oculus3D say they'… Read more
A team of paleontologists at Yale University say they've been able to determine the actual colors of an extinct species of dinosaur.
While many of the illustrations of dinosaurs we see in movies and books are striking, the truth is that much of the way we depict our jurassic friends is based on educated guesswork. But a few teams of scientists now say they have been able to determine a dinosaur's coloring with more precision. And one dino, in particular, has been color-mapped from head plume to toe.
Anchiornis huxleyi was a four-winged, feathered dinosaur that lived during … Read more
Solar power, it turns out, can mean more than just clean electrons and home hot water systems.
Chevron on Friday disclosed plans to use solar thermal technology from BrightSource Energy to enhance oil recovery from an aging well in central California.
The system will use 7,000 mirrors on Chevron-owned land to reflect light onto a tower to make steam. The steam will be pumped underground to heat up heavy oils and make them easier to extract, according to a Reuters report. Right now, Chevron uses natural gas to make steam.
Concentrating solar power has emerged as one of the … Read more
