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... Paris climate accords look more and more like fantasy; the reality could be far worse
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... 
Today, there are roughly 750,000 plug-in electric vehicles on U.S. roads and about 3,800 powered by hydrogen fuel cells. Proponents of each type of vehicle argue strenuously that their powertrain is a better way to produce vehicles with zero emissions from the tailpipe. Electric cars can be charged at home overnight, and electricity in many areas... 
One of California's largest electricity producers recently published a white paper that analyzed how the state will achieve its 2030 greenhouse-gas targets—and it called into question targets set forth by California regulators. Specifically, Southern California Edison (SCE) said the targeted 4 million electric vehicles isn't nearly enough to... ![Greenhouse-gas emissions of battery-electric vehicles globally in MPG equivalent [U of Michigan TRI]](https://images.hgmsites.net/tmb/greenhouse-gas-emissions-of-battery-electric-vehicles-globally-in-mpg-equivalent-u-of-michigan-tri_100631743_t.gif)
When electric cars first arrived in 2011, it was a reasonable question: Aren't you just shifting emissions from the tailpipe to the smokestack? The answer is yes, but the carbon emissions per mile of an electric car—properly measured on a wells-to-wheels basis—are virtually always lower than those of a gasoline or diesel car. It's not... 
On August 10, the U.S. Environmental Protection Agency announced it would reopen the Comment Period for the vehicle-emission standards for model years 2022 through 2025 it had finalized in January. The auto industry and its lobbyists had complained that the agency had moved too quickly, despite its issuance last summer of a voluminous Technical... 
The best analog to EPA administrator Scott Pruitt's latest action might be for the U.S. Geological Survey to undertake a "scientific critique" of theories that the world is round. After all, numerous authoritative sources over the years have raised doubts that the Earth is not flat. Surely their views deserve to be aired. Late last week, it... 
It's now clear that the zero-emission vehicles of the future will be powered by electric motors. The electricity to power those motors, however, will come from one of two competing technologies: high-capacity batteries or hydrogen fuel cells. The debate over which technology is superior, which has the lowest wells-to-wheels carbon footprint, and... 
The new U.S. president, Donald Trump, is working to eradicate every Obama policy to limit the carbon emissions that contribute to climate change. Having variously called the science behind climate change a "Chinese plot" to hurt the U.S. and referred to it using an expletive for bovine excrement, this shouldn't come as a surprise. He pledged to do... 
The new U.S. administration has made it clear that it does not accept the scientific consensus on climate change. From President Donald Trump down through his nominees for key roles—Scott Pruitt for EPA adminstrator, Rick Perry for Department of Energy head, and others—key elected and appointed officials have rejected the idea of human...
