266 Current news about the topic carbon dioxiderss
After taking a rented camper outfitted with special equipment to measure methane on a cross-continent drive, a UC Santa Barbara scientist has found that methane emissions across large parts of the U.S. are higher than currently known, confirming what other more local studies have found. Their ...
New technology offers the promise of reducing billions of dollars of losses that occur each year from the silent, invisible killer of fruits, vegetables and cut flowers — a gas whose effects are familiar to everyone who has seen bananas and other fruit ripen too quickly and rot. That's the ...
Researchers launch environmental 'game' for citizen scientists
Climate science researchers from Arizona State University are launching a first-of-its kind online "game" to better understand the sources of global warming gases. By engaging "citizen scientists," the researchers hope to locate all the power plants around the world and quantify their carbon ...
Wild fire residue is washed out of the soil and transported to the sea by rivers
Wild fires turn millions of hectares of vegetation into charcoal each year. An international team of researchers led by Thorsten Dittgar from the Max Planck Institute for Marine Microbiology in Bremen and Rudolf Jaffé from Florida International University's Southeast Environmental Research ...
Scientists at Lawrence Livermore National Laboratory (LLNL) and UC Berkeley and have discovered new materials to capture methane, the second highest concentration greenhouse gas emitted into the atmosphere. Methane is a substantial driver of global climate change, contributing 30 percent of ...
Directly removing CO2 from the air has the potential to alter the costs of climate change mitigation. It could allow prolonging greenhouse-gas emissions from sectors like transport that are difficult, thus expensive, to turn away from using fossil fuels. And it may help to constrain the ...
UC research explores how efforts to keep urban lawns looking green and healthy might negate the soil's natural ability to store atmospheric toxins
Amy Townsend-Small, a UC assistant professor of geology and geography, shows the effects lawn management techniques have on greenhouse gas production in urban landscapes. She says there's a high energy cost associated with common lawn-care methods such as mowing, irrigation and fertilization ...
By using seaweed as the biomass source, scientists in the UK have made mesoporous material without the need for costly processes such as supercritical carbon dioxide drying. The materials produced have applications for new, low-cost and sustainable structured materials in monolithic form.
New method is environmentally friendly and inexpensive
A team of Virginia Tech researchers has discovered a way to extract large quantities of hydrogen from any plant, a breakthrough that has the potential to bring a low-cost, environmentally friendly fuel source to the world. "Our new process could help end our dependence on fossil fuels," said ...
Share of biomethane in natural gas fuel has more than doubled since 2012
In the past year, the share of biomethane in natural gas fuel has risen from 6 to over 15 percent. In Germany, the renewable natural gas alternative is already available at one out of every three natural gas filling stations. Over 80 percent of the biomethane is produced from agricultural ...
