Carbon dioxide, in its ionic form bicarbonate, has a regulating function in the splitting of water in photosynthesis, researchers have found. This means that carbon dioxide has an additional role to being reduced to sugar. The pioneering work opens up a new research field where researchers can investigate possible biological and ecological consequences of the dual role of carbon dioxide.
Research on the behavior of coral reef fish at naturally-occurring carbon dioxide seeps in Milne Bay in eastern Papua New Guinea has shown that continuous exposure to increased levels of carbon dioxide dramatically alters the way fish respond to predators.
Wrangling over wording of the summary of the latest U.N. climate report foreshadows worse to come in treaty talks.
A decades-long debate over the dominant way that nitrogen is removed from the ocean may now be settled. Researchers found that both of the nitrogen 'exit strategies,' denitrification and anammox, are at work in the oceans. The debate centers on how nitrogen -- one of the most important food sources for ocean life and a controller of atmospheric carbon dioxide -- becomes converted to a form that can exit the ocean and return to the atmosphere where it is reused in the global nitrogen cycle.
Water: too much, too littleClimate change may accentuate seasonal differences in moisture availabilityClimate change will reduce water availability during dry seasons and increase it during wet seasons around the globe, new research suggests. It also finds there will be large regional variations in water-related impacts.

April 10, 2014 | Climate change will reduce water availability during dry seasons and increase it during wet seasons around the globe, new research suggests. It also finds there will be large regional variations in water-related impacts. Some areas may see an increase in both droughts and floods by the later part of the 21st century.

Leviathan of last resort
Tom Steyer is betting that campaigning on climate change can win elections. Is the verdant billionaire right?
DEMOCRATS have often feared big money in American politics, perhaps because most of it doesn’t go their way. When the Supreme Court struck down the caps on aggregate campaign donations last week, Republicans, broadly speaking, cheered and Democrats jeered. In the 2012 election cycle, four of the five biggest donors to superPACs—independent groups that raise money, often from the extremely rich, and spend it on outlandish political advertising—were Republicans.
Tom Steyer, a San Francisco-based billionaire who worries about climate change, is doing his best to help his fellow Democrats get over their qualms. Perhaps best known for his opposition to the ...
World Health Organisation joins with US politicians and healthcare companies in criticising $1,000-a-day price of Gilead Sciences’ pioneering treatment
A copper-based catalyst that produces large quantities of ethanol from carbon monoxide gas at room temperature has been developed by scientists. This promising discovery could provide an eco-friendly alternative to conventional ethanol production from corn and other crops, say the scientists.
People who pack their cars and drive like Clark Griswold in National Lampoon's 'Vacation' pay a steep penalty when it comes to fuel economy. For the study, researchers tested a sport utility vehicle and a compact sedan with various configurations, including underinflated tires, open windows, and rooftop and hitch-mounted cargo. The researchers tested the vehicles at a variety of speeds with the different configurations. While the findings were not unexpected, they serve as a reminder of how drivers can save money by taking simple measures.
Some thoughts on the challenges facing a nine-part Showtime series on global warming.
There is evidence that efforts to raise public concern about climate change by linking it to present-day natural disasters will backfire.
A fraction of the carbon that finds its way into Earth's oceans -- the black soot and charcoal residue of fires -- stays there for thousands for years. A first-of-its-kind analysis shows how some black carbon breaks away and hitches a ride to the ocean floor on passing particles.
Research is offering hospitals and trauma centers a unique, accurate and scientific approach to making decisions about transporting critical-care patients by air or by ambulance. Geographic Information Systems (GIS) has been in existence since the 1960s, and was first developed in Canada to manage land inventory. The popularity of the technology didn't increase until the rise of personal computers in the late 20th century. GIS now has a wide range of applications from business operations to transportation, conservation and agriculture, urban planning and more areas.
Future generations will have to pay more for today's carbon emissions than what governments across the world currently understand. The climate models used by policymakers around the world to estimate the economic and social costs of CO2 emissions have to be improved according to experts.
Large weather events, such as snowstorms and heavy storms that cause power outages, can lead to an increase in the number of reported carbon monoxide exposures. Researchers explored the link between these major storms and the rise in carbon monoxide exposure cases. They found that portable generators were the most common source of carbon monoxide exposure after storms which resulted in power losses; car exhaust was the most frequent source of exposure after heavy snowstorms.
Small but prolific predators, salamanders affect the ecosystem of a forest and collectively could help stave off climate disaster.
Scientists have made a surprising discovery about the degradation of solar cells that could help pave the way to creating a longer lifetime for these cells. Key factors for creating cost-efficient solar cells to compete with conventional energy sources like fossil fuels include fabrication cost, efficiency and lifetime of the cells.
If you think transportation solutions are essential for reducing greenhouse emissions and growing economic opportunity in rapidly-expanding cities, think again. Scientists now say we're looking at the problem the wrong way.
A veteran of environmental regulation and management seeks a non-hysterical approach to climate progress.
Researchers have found that arid areas, among the biggest ecosystems on the planet, take up an unexpectedly large amount of carbon as levels of carbon dioxide increase in the atmosphere. The findings give scientists a better handle on the earth's carbon budget -- how much carbon remains in the atmosphere as CO2, contributing to global warming, and how much gets stored in the land or ocean in other carbon-containing forms.
