4 Key Problems With Measuring EV Pollution vs. Gas Cars — Eric Jaffe | CityLab

Posted by in category: environmental

“People basically have to buy a new gas car to get a cleaner gas car. If you own an EV for a decade, on the other hand, it has the potential to get cleaner every year as the electricity grid gets cleaner—in a sense, updating itself in real-time. ‘Only electric cars get cleaner as you drive them.’” Read more

Electric Vehicles Go the Distance with Fast Charging — By Reed McManus | Sierra Magazine

2015-7-EVGuide-illo-WB

I’M driving 550 miles in three days, all by myself, mainly for the fun of it—and I’m not an environmental villain. Behind the wheel of a borrowed bright-red electric Tesla Model S, I click off the miles as I head south from the San Francisco Bay Area on Interstate 5 through California’s San Joaquin Valley, feeling virtuous because my tailpipe spews no pollution.

Accelerated modern human–induced species losses: Entering the sixth mass extinction | Science Advances

Posted by in categories: education, environmental, ethics, governance, law enforcement, science, security

Unknown


“The evidence is incontrovertible that recent extinction rates are unprecedented in human history and highly unusual in Earth’s history. Our analysis emphasizes that our global society has started to destroy species of other organisms at an accelerating rate, initiating a mass extinction episode unparalleled for 65 million years. If the currently elevated extinction pace is allowed to continue, humans will soon (in as little as three human lifetimes) be deprived of many biodiversity benefits.”

CRISPR, the disruptor — Heidi Ledford | Nature

Posted by in categories: biological, DNA, environmental

“Researchers are considering how CRISPR could or should be deployed on organisms in the wild. Much of the attention has focused on a method called gene drive, which can quickly sweep an edited gene through a population. The work is at an early stage, but such a technique could be used to wipe out disease-carrying mosquitoes or ticks, eliminate invasive plants or eradicate herbicide resistance in pigweed, which plagues some US farmers.” Read more
