A new method for producing electricity from carbon dioxide could be the start of a classic trash-to-treasure story for the troublesome greenhouse gas, scientists are reporting. Described in an article in ACS’ newly launched journal Environmental Science & Technology Letters, the method uses CO2 from electric power plant and other smokestacks as the raw material for making electricity.
They partly attribute the observed warming, and preceding cooling trends to ocean circulation changes induced by global greenhouse gas emissions and aerosols predominantly generated in the Northern Hemisphere from human activity.
In response to a relative slump in Solar Power / Photovoltaic sales in domestic and international markets, China's State Council has backed a target for the country to massively increase installed solar power to 35GW by 2015.
A new study estimates that global sea levels will rise about 2.3 meters, or more than seven feet, over the next several thousand years for every degree (Celsius) the planet warms.
New research has shown surface ice melt will be the dominant process controlling ice-loss from Greenland. As outlet glaciers retreat inland the other process, iceberg production, remains important but will not grow as rapidly.
For the past 40 years — as far back as satellite records show — the frequency and intensity of tropical cyclones has remained relatively stable: About 90 of these storms spin through the world each year, and over the decades, cyclones’ average intensity and maximum wind speed have also remained consistent.
Scientists from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory (BNL), working with colleagues from Pacific Northwest National Laboratory (PNNL), will conduct a field campaign this summer and fall in the skies over the Pacific Northwest and Tennessee to measure the evolution of aerosols in wildfires and prescribed agriculture burns, respectively.
Policymakers should be paying more, rather than less, attention to tackling climate change in economically tough times, a new study suggests. As economies have stagnated major emitters of CO2 seem unwilling to accept binding emissions reduction targets. But findings, published this week in Nature Climate Change, show the social cost of carbon dioxide is higher in a low economic growth world.
Study shows the atmospheric CO2 has big consequences for the tiny bacteria that are the foundation of most life in the sea
One out of ten people on Earth is likely to live in a climate impact hotspot by the end of this century, if greenhouse gas emissions continue unabated. Many more are put at risk in a worst-case scenario of the combined impacts on crop yields, water availability, ecosystems, and health, according to a study now published online by the Proceedings of the National Academy of Sciences (PNAS).
