New report shows oceans warming much faster than anticipated (Updated)
Update: The scientists behind this study have updated their report in the journal Nature acknowledging key errors in the study. The note that the data regarding scientific uncertainty was mishandled, which inflated the amount of heat the oceans have absorbed. The central finding that the oceans...

Report: Trump EPA plans to cancel California emissions waiver
The EPA is planning to cancel the special waiver that California has relied on since 1970 to set its own emissions standards, according to a Bloomberg report. As part of its plan to reverse a program to steadily tighten fuel economy standards that it coordinates with California and the National...

EPA staffers told how to downplay climate change in leaked memo
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...

Are you optimistic about efforts to address climate change? Take our Twitter poll
Ten years ago, energy security may have been as much a driving force behind electric cars for U.S. policymakers as climate change. Now, with continuous growth in domestic oil and gas production over that period, you just don't hear energy security discussed as much. Scientists agree that the...

We often speak of methods and technologies we can employ as a society to curb climate change, either by reducing carbon emissions or through other means. But less frequently do we talk about them in real terms, including how much excess carbon these methods and technologies can pratically remove from the atmosphere. That's where Drawdown, a climate action plan detailing 80 different possibilities, comes into play. DON'T MISS: Most-accurate climate-change models suggest worst effects on global weather Based on a book of the same name, the Drawdown website is a venerable resource that takes a...

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...

EU to slash vehicle carbon emissions one third more from 2021 through 2030
Europe already has tough standards for reducing carbon-dioxide emissions in current and future vehicles. Now they're going to get significantly tougher between 2021 and 2030. At its weekly cabinet meeting, held Wednesday, the European Union formally adopted far more stringent requirements for...

Climate change all manmade, say actual scientists: awkward for Trump science deniers
When the Environmental Protection Agency quietly issued its new four-year plan in mid-October, the phrase "climate change" did not appear anywhere in the 38-page document. It is now clear the Trump Administration intends to delay, halt, or erase government efforts to limit U.S. emissions of carbon...

Could California climate-change rules raise gas price enough to backfire?
California has by far the most aggressive climate-change policies in the nation, and the state is a global leader in plans to reduce carbon-dioxide emissions. It's also the world's eighth-largest economy, with a growing population, soaring economic output, and a resolutely progressive legislature...

Buying A New Car Is Greener Than Driving An Old One...Really
You've probably heard it at some point: A friend claims his older vehicle is far greener than the new car with much higher fuel economy you just bought That's because, he says, the old car didn't require all the energy and natural resources your car consumed as it was built. But is that older car...

Will European Fuel-Efficiency Tests Get More Realistic Under New Rules?
When we report on European market cars, we'll often advise you to take their official fuel consumption ratings with a pinch of salt. The current New European Drive Cycle (NEDC) test simply isn't very real-world relevant, unrealistically inflating a car's economy potential. That may change in the...

Electric Cars Cut Greenhouse Gases Even More Than Expected, NASA Says
A trial program with electric cars at the Kennedy Space Center is going better than expected, cutting greenhouse gas emissions in company vehicles. In fact, the center's sustainability office suggests the results are 10 times better than those expected--electric cars are making a real impact...

Renault Study Shows Electric Cars Far Greener Than Gasoline--In France
With relatively few electric vehicles on the market, drawing direct comparisons with regular gasoline and diesel vehicles is surprisingly difficult--not many vehicles are sold with all three drivetrains. The Ford Focus is one, and Renault's Fluence sedan is another. Now, reports Autoblog Green, the...

Ford Cut Plant CO2 Emissions By A Third Since 2000; Another Third By 2025 Targeted
There's more to making a car green than just the car itself. Ideally, the whole process of making the car should be as environmentally-friendly as possible too. Ford is doing just that, having cut global carbon dioxide emissions at its plants by over a third since 2000. CO2 emissions have dropped...

Is 400 PPM Actually The Most Important Metric Ever For Cars?
You won't have been able to feel it, but on Friday the levels of carbon dioxide in the atmosphere hit a milestone amount. For the first time in recorded history, CO2 levels averaged 400 parts per million (ppm), or 0.04 percent, at a monitoring station on Mauna Loa, Hawaii. And, say scientists, it's...

Biofuel From CO2: Too Good To Be True?
We currently have two main issues in our transport future. The first is cutting down on fossil fuel use, ensuring our finite supplies can be used for longer than our current consumption levels would account for. The second is reducing greenhouse gas emissions, helping prevent runaway climate...
