Is This Spindly Fossil a 3-Billion-Year-Old Eukaryote?

spindle_eukaryote_fossil_Geology_Christopher_H_House_200

“Surprisingly Large and Complex” 3 Billion Year Old Fossil ID’d as ex-Plankton Eukaryotes may not be the most abundant organisms on earth (that would be viruses, if you count them as alive), or the most ancient (bacteria and archaea are surely Eldest), but they have given Earth its most structurally entertaining passengers. Pterodactyls, anglerfish, slime [...]

How Much Nature Do We Have to Use?

It’s so easy to slip into debt, but so hard to dig oneself out. Just ask the typical wage earner—even business and national leaders. People who know better still wait for that next paycheck, assumed pay raise or small miracle to help them catch up. As any accountant will tell you, accumulating debt is not [...]

US-climate-change-negotiator-todd-stern

“There will be coal burning.” Negotiators from around the world produced a four-page climate-change accord (pdf) after some sleep-deprived haggling over the weekend in Lima, Peru, but the agreement could be summed up in those five words. For the first time, all nations agreed that all nations must have a plan to curb greenhouse gases. [...]

Clean Coal Era Begins

boundary-dam-power-plant

On October 2, the Boundary Dam power plant in Saskatchewan became the first full-sized coal-fired boiler to capture the copious carbon dioxide that had previously billowed from its smokestack, preventing the greenhouse gas from entering the atmosphere. On the resulting invisible stream of hot smoke ride the hopes of combating climate change while still burning [...]

U.S. Starts National CO2 Permits, Cap and Trade Works, and Other Surprises

thomas-c-ferguson-power plant

The U.S. has begun to regulate greenhouse gas emissions from power plants—quietly, with little fanfare and starting in Texas. The Thomas C. Ferguson Power Plant in Llano County is being modernized with the installation of a combined cycle natural gas-fired turbine for improved efficiency at generating electricity. The refurbished “peaker” plant—so-called because it is fired [...]

Climate projections: Visualizing global warming in the round

science on a sphere

BOULDER—Thin clouds of dust blow off the west coast of Africa toward the Caribbean; wisps of black carbon emissions roil over the U.S. These big-picture global chemical equations can often get lost deep in complex climate datasets. But a seemingly simple idea is helping school children and scientists alike visualize models of carbon, climate and [...]

What happens when coal is gone?

LINDAU, Germany–What’s the best way to address a politically charged topic such as the future of energy? Remove the politics. “We’re going to skip over the politics,” Robert P. Laughlin, who won a Nobel Prize for physics in 1998, told a rapt audience of young scientists and others here at the 60th annual Nobel Laureate [...]

No shenanigans here, U.S. carbon emissions are down

Credit: Saul Loeb/AFP/Getty Images

U.S. energy-related carbon emissions are down in 2012 according to the Energy Information Administration: Now there are several ways to say that carbon emissions are down. A common practice is to use carbon intensity, which is a handy policy metric for measuring carbon emissions against economic output (tons of carbon dioxide emissions to GDP). But [...]
