The first detailed map of aboveground forest carbon stocks of Mexico has been released by researchers. This carbon stock inventory is very valuable for Mexico, as one of the first tropical nations to voluntarily pledge to mitigation actions within the context of the United Nation's Reducing Emissions from Deforestation and forest Degradation program.
Offshore wind power is a valuable source of renewable energy that can help reduce carbon emissions. Technological advances are allowing higher capacity turbines to be installed in deeper water, but there is still much unknown about the effects on the environment. Scientists have now reviewed the potential impacts of offshore wind developments on marine species and make recommendations for future monitoring and assessment as interest in offshore wind energy grows around the world.
A new analysis of global energy use, economics and the climate shows that expanding the current bounty of inexpensive natural gas alone would not slow the growth of global greenhouse gas emissions worldwide. Recent advances in gas production technology based on horizontal drilling and hydraulic fracturing -- also known as fracking -- have led to bountiful, low-cost natural gas. Because gas emits far less carbon dioxide than coal, some researchers have linked the natural gas boom to recent reductions in greenhouse gas emissions in the United States. But could these advanced technologies also have an impact on emissions beyond North America and decades into the future?
Since the first undersea methane seep was discovered 30 years ago, scientists have meticulously analyzed and measured how microbes in the seafloor sediments consume the greenhouse gas methane. They have now found a type of rock known as authigenic carbonate also contains vast amounts of active microbes that take up methane. This demonstrates that the global methane process is still poorly understood.
The epaulette shark displays physiological tolerance to elevated carbon dioxide in its environment after being exposed to carbon dioxide levels equivalent to those that are predicted for their natural habitats in the near future.
Naomi Klein says climate campaigners should attack capitalism because it already is a popular target.
Species that live in and erode coral reefs will play a major role in determining the future of reefs, new research suggests. The research highlights the delicate balance that exists between bioerosion and carbonate production on coral reefs.
A team of scientists have developed a new way of identifying genes that are important for photosynthesis in maize, and in rice. Their research helps to prioritize candidate genes that can be used for crop improvement and revealed new pathways and information about how plants fix carbon.
NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has provided scientists their first look at a storm of energetic solar particles at Mars, produced unprecedented ultraviolet images of the tenuous oxygen, hydrogen, and carbon coronas surrounding the Red Planet, and yielded a comprehensive map of highly-variable ozone in the atmosphere underlying the coronas.
A Defense Department report says the military will begin planning for the risks of climate change across all of the armed forces’ operations.
Increasing reliance on renewable energies is the way to achieve greater carbon dioxide emission sustainability and energy independence. As such energies are yet only available intermittently and energy cannot be stored easily, most countries aim to combine several energy sources. Scientists have now come up with an open source simulation method to calculate the actual cost of relying on a combination of electricity sources.
TEN years ago the Bill & Melinda Gates Foundation began divvying up the money for what it hoped would be a novel approach to the task of solving the world’s health problems. The new programme’s organisers, led by Mr and Mrs Gates themselves, had identified 14 “grand challenges” in the field—from “preparing vaccines that do not require refrigeration” to “developing a genetic strategy to deplete or incapacitate a disease-transmitting insect population”—and had invited suggestions from the world’s scientists for specific projects of a sort that might not otherwise get funded, which might meet these goals. Not surprisingly, since the foundation had announced a year earlier that it was making $200m available to pay for all this, hundreds of research groups lined up to dip their bread in the gravy.A bold idea then, perhaps bordering on the naive. And that word was used more than once by Mr Gates, in a tenth-anniversary review meeting of the Grand Challenges in Global Health programme, as it is known, which was held this week in Seattle. He and his fellow board members had hoped their philanthropic version of venture capitalism would lead to breakthroughs in the...
Conventional estimates for the collapse of the Aegean civilization may be incorrect by up to a century, according to new radiocarbon analyses.
Scientists have developed a slurry-based process that can revolutionize carbon capture. The slurry, consisting of a porous powder suspended in glycol, offers the efficient large-scale implementation of a liquid while maintaining the lower costs and energy efficiency of solid carbon-capturing materials.
After a period of decline, The Times is refocusing its attention on climate change.
Because of the deforestation of tropical rainforests in Brazil, significantly more carbon has been lost than was previously assumed. The effect of the degradation has been underestimated in fragmented forest areas, since it was hitherto not possible to calculate the loss of the biomass at the forest edges and the higher emission of carbon dioxide.
Every day, private motor transportation causes traffic jams, pollution and a shortage of parking spaces. The number one mode of transportation – the automobile – is one of the biggest burdens on urban spaces and their inhabitants. But does it have to be this way? Other options have emerged that offer reliable, low-emission mobility in cities and the surrounding areas: not just electromobility, but digital networking and car sharing, too.
Scientists have probably underestimated warming since the 1970s, a study says. That could affect some climate change measures.
A future where electricity comes mostly from low-carbon sources is not only feasible in terms of material demand, but will significantly reduce air pollution, a study says.
Efforts to reduce China’s carbon dioxide emissions are being offset by the country’s rampant economic growth, according to new research. Research reveals how carbon efficiency has improved in nearly all Chinese provinces. But the country’s economic boom has simultaneously led to a growth in CO2-emitting activities such as mining, metal smelting and coal-fired electricity generation – negating any gains.
