China pledges to clean up Beijing by 2008

(Phys.org) —Air quality and visibility have improved dramatically at national parks and other areas of national scenic value in association with reduced air pollution emissions, according to new data analysis ...

(Phys.org) —One often ignored consequence of global climate change is that the Northern Hemisphere is becoming warmer than the Southern Hemisphere, which could significantly alter tropical precipitation ...

Most organisms would die in the volcanic sulfur pools of Yellowstone and Mount Etna. Robust simple algae call it home, and their secrets to survival could advance human medicine and bioremediation.

Programs that allow facilities to buy and sell emission allowances have been popular and effective since they were introduced in the U.S. two decades ago. But critics worry the approach can create heavily polluted "hot spots" ...

Australian researchers have suggested that nations should abandon the concept of carbon emissions trading in favor of a carbon swap bank that might lead to genuine reductions in the amount of carbon dioxide greenhouse gas ...

When it comes to forming the droplets that make up clouds, a little oily and viscous organic material apparently doesn't matter that much. And that's good news for reducing the uncertainty of climate model predictions.

What people take from nature – water, food, timber, inspiration, relaxation – are so abundant, it seems self-evident. Until you try to quantitatively understand how and to what extent they contribute ...

Farmers have resumed planting rice for market only 15 kilometres (nine miles) from Japan's crippled Fukushima Daiichi nuclear power station, a local official said Wednesday.

Scientists and engineers must join together in a major new effort to educate the public and decision makers on a crisis in providing Earth's people with clean water that looms ahead in the 21st century. That's the focus of ...

The University of Stirling is to lead a new project to develop a strategy for using nutrient-rich aquatic biomass waste – from ponds, wetlands and other water-bodies – in farming, as an environmentally ...

Environmental projects which map some of the most important benefits we get from nature have been brought together for the first time in an online database, following national survey work by researchers in the University ...

About 55.5 million years ago, geologically rapid emission of a large volume of greenhouse gases at the Paleocene-Eocene boundary (PETM) led to global warming of about 5oC, severe ocean acidification, and ...
