When top U.S. scientists released the fourth National Climate Assessment, it spelled out one blunt conclusion: human activity in releasing carbon dioxide into the atmosphere caused the climate change that has warmed the globe.

EPA head: new report that climate change is manmade has ‘no bearing’ on plans to end climate action
When top U.S. scientists released the fourth National Climate Assessment, it spelled out one blunt conclusion: human activity in releasing carbon dioxide into the atmosphere caused the climate change that has warmed the globe. Mandated for release every four years, the report will apparently have no sway over EPA administrator Scott Pruitt, a... ![2017 Chevrolet Bolt EV Premier and 2017 BMW i3 electric car, Aug 2017 [photo: Tom Moloughney]](https://images.hgmsites.net/tmb/2017-chevrolet-bolt-ev-premier-and-2017-bmw-i3-electric-car-aug-2017-photo-tom-moloughney_100618415_t.gif)
While it's clear that the transition to plug-in electric cars is accelerating across the globe, in the short term electric cars still face numerous hurdles. Charging infrastructure remains inconsistent, vehicle range is still an issue, and ultimately, the inherent and appropriate conservatism of car buyers themselves acts as a brake on adoption of... 
This month's best deals for hybrid, electric, and fuel-efficient cars are in and buyers will find a handful of eco-friendly bargains. Most cars have held their spots from October 2017, but a few newcomers may surprise shoppers, including the brand-new 2018 Toyota Camry Hybrid. Read on to see where the best deals can be had. DON'T MISS: Costco... 
Amazon, once a humble bookseller, now dips its toes into numerous technology realms. Its next potential act? Perhaps it will be drones that can charge electric cars on the fly. The online retailer and technology company filed an application to patent a drone specifically built for electric-car charging when a charging station isn't nearby. The... 
Tesla has never built anything but battery-electric cars. Now a Dutch gasoline company believes it's improved upon the Silicon Valley automaker's design with a hydrogen fuel cell—so much so that it wants to sell its solution to the general public. The Holthausen Group, a Dutch gasoline supplier, claims it built a hydrogen fuel cell-powered... ![Donald J.

Following President Donald Trump's decision to pull the United States from the Paris Climate Accord—a global pact to reduce carbon output and curb climate change—only two other nations had not signed the treaty. Now, the U.S. sits alone and isolated internationally on climate policy. This week Syria, the final nation invited to join... 
Electric cars provide a zero-emission driving experience, but one of the most important raw materials for their batteries—cobalt—has a supply chain that needs some work. About half of the world's cobalt supply comes from the Democratic Republic of Congo (DRC), a country with high rates of child labor under very poor working conditions... 
Both Hyundai and Kia planned to approach the electric and plug-in car market aggressively, but now the Korean siblings plan to boost production even over totals announced earlier this year. This past summer, both brands said they would increase their electrified car production to 50,000 units next year. Now, according to a report earlier this... 
Luxury and sports car maker Porsche isn't concerned with the sweeping changes vehicle electrification will bring. In fact, the brand believes it will maintain its steady profit and 15-percent operating margin into the future, despite the major investments in electric and plug-in cars it plans to make. While Porsche can't pass through some of those... 
Workhorse, best known for its forthcoming W-15 range-extended electric pickup truck, today revealed its newest vehicle. The N-Gen electric van will tackle the important "last-mile" delivery segment, performed by vehicles that deliver parcels over relatively short distances. Not only makers like Workhorse but also their fleet customers have come to... ![The White House, Washington, D.C.

The United States tax code hasn't seen a major overhaul in decades, and the current Congress—along with the Trump administration—may be learning, or re-learning, why. Numerous opponents have moved swiftly to condemn various aspects of the draft Tax Cuts and Jobs Act (HR1) proposed in the House of Representatives, released last... ![2015 Nissan Leaf at evGo fast charger at Livingston Mall, Livingston, NJ [photo: John Briggs]](https://images.hgmsites.net/tmb/2015-nissan-leaf-at-evgo-fast-charger-at-livingston-mall-livingston-nj-photo-john-briggs_100558580_t.gif)
One way for electric-car charging networks to make the public charging experience more user-friendly is through the use of smartphone apps to replace the RFID cards that identify members and let them initiate charge sessions. Not only do they provide electric-car drivers a host of capabilities, but they allow drivers to pay for charging sessions... 
A group of automakers in Europe announced on Friday they will launch "Ionity," a network of high-power fast-charging stations to build out the continent's infrastructure for electric-car travel. When it's finished in 2020, Ionity will include 400 charging stations across multiple countries, supporting all electric cars that adhere to the Combined... 
The huge annual SEMA show for builders and owners of highly customized cars brings out some truly bizarre creations. Only at SEMA will you see vehicles like the one-of-a-kind PriuSRT8, a Toyota Prius with a gas-guzzling V-8 engine under its hood that effectively turns the hybrid's green credentials on its head. The once gas-sipping hatchback... 
Over seven years of plug-in electric cars and 20 years of hybrids, the pickup truck sector remains largely untouched. GM sold hybrid Chevrolet and GMC pickups for a few years, and Ford plans an F-150 hybrid in 2020. A startup company now called Workhorse (nee AMP) noticed that white space and made a bold play for the market with its W-15 plug-in... 
Although claims of imminent volcanic eruption are likely exaggerated, any eruption of what's known as the Yellowstone Supervolcano would cause global chaos. Through intense monitoring programs, scientists have a clear idea of the Yellowstone volcano's behavior. Now NASA scientists are exploring a radical idea that could one day neutralize the... 
First-hand details about the Tesla Model 3 remain almost as rare as the cars themselves; Tesla has built only a few hundred Model 3 electric cars since its launch in July Now a new video provides an incredibly in-depth look at Tesla's mass-production car, though we suspect it may have been approved by the company. It gives us a detailed look at... 
Less than two years from now, barring action by the Trump administration, a National Highway Traffic and Safety Administration rule will require hybrid and electric cars to produce an audible noise under 19 mph. Alongside its Nissan IMx self-driving electric SUV concept it launched at the recent Tokyo Motor Show, the maker of the world's... 
The way a driver operates a car can produce very different fuel-economy numbers, and when driving downhill, two notable techniques come into play. The first is leaving the car in gear and using so-called engine braking to provide at least some deceleration. But many believe putting a car in neutral uses less fuel, followed by use of the brakes to... 
Although electric cars offer numerous benefits in engineering, design, and zero-emission operation, their overall weight remains a hurdle for automakers, especially as bigger batteries with longer ranges become more important. It now appears that Toyota may look to airless tires as a way to cut weight in its future electric cars: It debuted the...
