The US has stricter ozone rules but the limits lag guidelines set by some other countries and more coordination in regulation is needed to address air pollution globally.
Scientists are studying how carbon-rich permafrost known as yedoma acts much like frozen vegetables to hungry microbes – and is becoming an additional source of heat-trapping gases.
Exxon wasn’t the only giant corporation to have climate scientists in the 1980s. Scientists at GM and Ford also honed in on climate change, but they – and their companies – took very different paths.
Should conservationists ‘sell’ the value of nature by focusing on the ecosystem services nature provides people? Surveys show this may be the wrong tack.
Did environmentalists force Shell to exit the Arctic? Not really. Blame economics and geopolitics first and foremost.
Volkswagen’s emissions cheat didn’t just anger owners and regulators; the cost to human health from violating air quality rules exceeds US$100 million.
Shell has abandoned oil exploration offshore Alaska for now but a variety of trends are driving the energy industry to take a fresh look at Arctic drilling.
Volkswagen’s emissions deception and a case of alleged price-gouging around pharmaceuticals are part of a troubling trend of businesspeople who operate with little regard for ethics.
Can VW rebuild public trust? Its survival may depend on repairing the image damage caused by deception over clean diesels.
After two years of negotiations, the UN Sustainable Development goals will be adopted today. How can society and government actually end poverty and achieve other lofty goals?
Hillary Clinton’s opposition to construction of the Keystone pipeline has little effect in the short term but reflects building “supply side” strategy of environmentalists to limit fossil fuel development.
Current clean diesel technology is more than capable of meeting tough air quality rules while still delivering excellent fuel performance. Biofuels could make it even cleaner.
A summit between officials from the US and China on climate change underscores the crucial role cities need to play in meeting national carbon-emission goals.
Federal agencies pay much of the cost to fight forest fires, which means taxpayers are subsidizing the risky practice of building more homes at the wildland-urban interface.
Using more accurate data, researchers find that waste disposal at methane-emitting landfills is two times greater than previous EPA estimates.
Agroecological techniques that mimic nature – the antithesis of GMOs and high-cost fertilizers – have made farmers in developing countries more resilient to extreme weather.
Field trials in Senegal show native shrubs can access deep-soil water and make it available to adjacent crops – a technique that could alleviate drought conditions in marginal lands around the world.
The future of two key energy policies – the EPA’s Clean Power Plan and Renewable Fuel Standard – will decide whether bioenergy will continue to grow in US or not.
According to scientists, tree-ring analysis shows that California drought is the worst it has been in 500 years.The study underscores the severity of current drought and the challenges of future water management in the state.
The combination of local fishing rights with adjacent marine reserves creates incentives to avoid overfishing and could improve nearshore, small-scale fisheries around the world.
If we burned all fossil fuels, the loss of ice in Antarctica would raise sea levels 160 to 200 feet, but even our current trajectory could lead to dramatic sea level rise.
El Niño explained: how it works, what a mega El Niño this year could bring and how global warming might affect future El Niño-driven weather patterns.
The UN climate talks in Bonn last week left many key issues unresolved, creating big challenges for forging a global deal in Paris later this year that would avert the worst effects of climate change.
Sophisticated models and supercomputers allow researchers to create a high-fidelity map of the Earth’s trees – and show that we’re losing billions of trees a year.
