Study draws link between climate and weather—via jet stream

ForestFor some, the evidence of global warming is hard to accept, especially when it has been difficult to draw the link between individual storms and an increase in atmospheric greenhouse gasses. Now a new study by a climate scientist at Pennsylvania State University has done just that. By studying the pattern of the jet stream, Professor Michael Mann...

Scientists find affordable way to recapture CO2 and burn it

ForestScientists at Harvard have developed a new method of scrubbing carbon from the atmosphere, and turning it into hydrocarbon fuels that could be burned in airplanes or even cars. The process has been demonstrated at a small scale and combines common technologies from the pulp and petroleum industries to capture carbon and hydrogenate it back into...

Pruitt’s EPA emission rollback reasoning may well fail in court

EPA administrator Scott Pruitt  [photo from 2014]Despite the sturm und drang around the announcement by embattled EPA chief Scott Pruitt that he will relax emission limits for 2022 through 2025 vehicles, not much will happen immediately.

He is likely the first EPA head to axe scientists from the...

EPA to ease emission limits, reports say, setting up clash with California

Chrome exhaust pipeThe omens have been accumulating for months, as bits of information dribble out of the regulatory rumor mill in Washington, D.C. Now we have the most concrete reports yet that the U.S. EPA plans to modify exhaust emission limits for vehicles in model years 2022 through 2025. The EPA delivered its draft Final Determination document to the Office of...

CA attorney general: we will fight looser fuel-economy, emission rules

National Plug-In Day 2012: San Francisco, with 60 Nissan Leafs in front of the Golden Gate BridgeLast Tuesday, EPA administrator Scott Pruitt said the agency does not intend to let California set the agenda for national emission limits on vehicles. He suggested to Bloomberg the EPA plans to cut emission rules aggressively to respond to carmakers' pleas for easing of the corporate average fuel economy rules for 2022 through 2025 that they had...
