A new report on pollution, economic growth, and renewable energy in California sheds new light on the link between emissions regulations and economic growth ahead of the Global Climate Action Summit in San Francisco next month. The report released Thursday shows that even as the state implemented stricter emissions standards than other states and... 
Scientists 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... 
One of the main objections that critics of global warming mitigation measures often cite is that they cost too much. A new study in the journal Nature takes issue with that conclusion. Several studies since 1991 have concluded that it is cheaper to develop new technologies to mitigate climate change than it will be to adapt to it. What those... 
With automotive emissions regulations again coming under political pressure, we thought we'd re run this Earth Day question from 2014 in an attempt to answer the question: Why all the fuss? Why do we still focus on green cars some 40 years after the EPA imposed the most significant emissions limits on cars? We hope it will provoke thought engender...

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. His determination last week that the Obama administration was "incorrect" and that the limits on those vehicles weren't needed kicks off a lengthy process of... 
President Trump has taken a lot of flack for pulling out of the Paris climate accords, claiming they were a bad deal for the country he leads. Perversely, the problem with the global climate treaty may not be that Trump's action made the potential for devastation worse, but rather that the effects of climate change are already on track to be so... 
While the name of EPA administrator Scott Pruitt is often preceded by "embattled" these days, his agency is now on record as rejecting its own recommendation of just 16 months ago. It concluded in July 2016 that the auto industry had handily met lower carbon-emission limits from 2012 through 2017—at lower cost and with more conventional... 
EPA administrator Scott Pruitt would be controversial even if he hadn't flown to Morocco in December (first-class, on the taxpayer dime) to lobby the country on the benefits of liquified natural gas while living in a condo owned by a lobbyist for the country's largest LNG exporter. He is likely the first EPA head to axe scientists from the...

The most recent detailed studies on the likely warming of Planet Earth are grim indeed, suggesting that we are collectively at "very high risk" for the most extreme effects of climate change. To stem that, mankind collectively will have to reduce its ongoing emissions of carbon dioxide radically and immediately. Now, one longtime advocate of...
