In a potentially historic agreement, a draft climate accord would have every country pledge to curb fossil fuels, but each would set its own goals.
Large-scale storage of low-pressure, gaseous hydrogen in salt caverns and other underground sites for transportation fuel and grid-scale energy applications offers several advantages over above-ground storage, says a recent study.
Heart disease patients have been advised to avoid being outside during rush hour traffic. The position paper on air pollution and cardiovascular disease also recommends decreasing the use of fossil fuels. “More than 3 million deaths worldwide are caused by air pollution each year. Air pollution ranks ninth among the modifiable disease risk factors, ahead of low physical activity, high sodium diet, high cholesterol and drug use,” a corresponding author noted.
Officials have sometimes referred to a 24-year-old clause that says countries should have “common but differentiated responsibilities,” meaning developed and developing nations have different standards to meet when it comes to taking action on...
Mars is a frigid desert, suggesting that the mother of all climate changes happened there, about four billion years ago. The question that haunts planetary scientists is why? And could it happen here?
Secretary of State John Kerry will attend climate talks in Lima, Peru, to encourage countries to strike an agreement on reducing carbon emissions.
The Philippines, taking the brunt of disastrous typhoons, is now challenging every nation to embrace emissions reductions.
Climate change attributable to human behavior “may have done a little bit of an add-on,” the study’s lead author said.
A new study on tropical shallow-water soft corals, known as gorgonians, found that the species were able to calcify and grow under elevated carbon dioxide concentrations. These results suggest that Caribbean gorgonian corals may be more resilient to the ocean acidification levels projected by the end of the 21st century than previously thought.
Wind turbine developments have no effect on property values of nearby homes and farms, according to new Canadian research. Researchers analyzed more than 7,000 home and farm sales in Melancthon Township and 10 surrounding townships in Dufferin, Grey, Simcoe and Wellington counties. Melancthon, located about 100 kilometres northwest of Toronto, is home to one of Ontario's first and largest wind farms; 133 wind turbines were erected between 2005 and 2008.
Outside investors seek to monetise opportunities, in rescue, healthcare and reconnaissance
As long ago as 1991, there were calls to pursue “soft,” not binding, steps toward a global climate treaty. Talks are progressing now because this shift has occurred.
Scientists see a large amount of variability in the El Niño-Southern Oscillation (ENSO) when looking back at climate records from thousands of years ago. Without a clear understanding of what caused past changes in ENSO variability, predicting the climate phenomenon's future is a difficult task. A new study shows how this climate system responds to various pressures, such as changes in carbon dioxide and ice cover, in one of the best models used to project future climate change.

Two campaigners for children's rights and education receive the Nobel Peace Prize, the deadline for America's budget and the conclusion of a conference in Peru on climate change
The Social Cost of Carbon puts a dollar value on the climate damages per ton of CO2 released, and is used by -- among others -- policymakers to help determine the costs and benefits of climate policies. A group of economists and lawyers urge several improvements to the government's Social Cost of Carbon figure that would impose a regular, transparent and peer-reviewed process to ensure the figure is reliable and well-supported by the latest facts.

TO GET to the tent city in the grounds of Peru’s defence ministry, where UN climate talks are being held between December 1st and 12th, delegates and hangers-on must pass an assault course. Its obstacles of steep walls, ropes across ditches and parallel bars, normally used by soldiers, are a reminder of the difficulties that negotiators face if they are to forge a new treaty in Paris in a year’s time to avert destructive climate change. If the Paris meeting is to succeed, the Lima get-together—officially the 20th Conference of the Parties to the UN Framework Convention on Climate Change—must agree on crucial preparatory steps. Morale is higher than it was a year ago. But it needs to ...
A rapid process of urbanization and an expanding middle class with increasingly western tastes will keep energy consumption and carbon dioxide emissions in China at high levels over the next 20 years. However, changes are unfolding in China that offer promise and opportunities for cutting emissions and for promoting sustainable energy and climate policies.
Amines bound by buckyballs can absorb carbon dioxide from emissions at industrial plants and at natural gas wells, according to new research. Tests from one to 50 atmospheric pressures showed the newly developed compound captured a fifth of its weight in carbon dioxide but no measurable amount of methane.
A research team has designed a new approach that could lead to underwater imaging lidars that are much smaller and more efficient than the current full-size systems. The new technology would allow modest-sized unmanned aerial vehicles (UAVs) carry bathymetric lidars, lowering costs substantially.
It takes just 10 years for a single emission of carbon dioxide (CO2) to have its maximum warming effects on the Earth. This is according to researchers who have dispelled a common misconception that the main warming effects from a CO2 emission will not be felt for several decades.
