In an opinion piece in the journal Nature , a team from the US and Europe suggests that the transition to a low-carbon world will create new rivalries, winners and losers, and that it is therefore necessary to put geopolitics at the heart of debates about the energy transition. abating carbon will create losers. Big green deal. ?This
watts per square meter warming effect from the carbon dioxide increase during that same period. The team concluded that models miss an important cooling factor if they don’t account for the influence of stratospheric aerosol, or don’t include recent changes in stratospheric aerosol levels. —John Daniel. Solomon, J. Daniel, R.

The results depend most sensitively on the grade of shale used, and the rate of carbonate mineral decomposition which causes inorganic CO 2 release, reports Brandt in a paper published online 25 August in the ACS journal Energy & Fuels. The high temperatures can cause carbonate minerals within the shale to decompose. These are ~1.5-1.75

Methane and black carbon (soot) are the second- and third-most powerful climate-warming agents after carbon dioxide. Methane and black carbon (soot) are the second- and third-most powerful climate-warming agents after carbon dioxide. Lead author Drew T.
Canada’s Minister of Environment and ClimateChange, Catherine McKenna, and the Chair of the California Air Resources Board, Mary Nichols, today signed a new cooperation agreement to advance cleaner vehicles and fuels. Canada is developing a Clean Fuel Standard that will cut emissions by 30 million tonnes in 2030.
Methane is the second most abundant greenhouse gas after carbon dioxide, albeit a distant second. Observations from satellites and ground sites suggest that biomass burning—the burning of plant and other organic material that releases carbon dioxide and methane—contributed about 20% of the total methane released into the atmosphere in 2007.
Burning methane by flaring as it is released converts it to carbon dioxide, another greenhouse gas but one that is less harmful on a pound-by-pound basis. The new data suggests we have overestimated flaring’s effectiveness and, as a result, underestimated its contribution to methane emissions and climatechange.
According to a Definitive Feasibility Study (DFS) completed in 2020, Ioneer will produce enough lithium carbonate to produce batteries for 400,000 EVs per year. Climatechange could impact the frequency and severity of future herbivory events because future conditions will likely be warmer and drier.). Tiehm’s buckwheat.
Ceres is a national network of investors, environmental organizations and other public interest groups working with companies and investors to address sustainability challenges such as global climatechange. < —Mindy Lubber, president of Ceres and director of the $9 trillion Investor Network on Climate Risk /p>.
A new study led by Colorado State University predicts significant climate benefits stemming from the use of advanced biofuel technologies. These results affirm the climate mitigation logic of biofuels, consistent with their prominent role in many climate stabilization scenarios. —Field et al. —John Field.
This is a key component of the global climate system, linking the cycling of water with energy and carbon cycles. Climatechange is expected to intensify the hydrological cycle and to alter evapotranspiration, with implications for ecosystem services and feedback to regional and global climate. —Jung et al.
The researchers determined the global warming potential, expressed in carbon dioxide equivalents (t e CO 2 ), for seven components of urban inventories: electricity, heating and industrial fuels, industrial processes, ground transportation, aviation, marine, and waste.

airports are increasingly experimenting with generating and storing electricity on site typically with solar power and batteries to curb carbon emissions, prepare for future electricity needs, and manage rising disruptions caused by climatechange and aging infrastructure. can help reduce an airports carbon footprint.
At EVmatch , we envision a distributed, equitable, and carbon-free clean energy economy that connects and elevates all people. That’s why we are always encouraged to learn about and partner with other companies that are identifying innovative ways to fight the growing climate crisis.
The findings suggest that in addition to carbon dioxide, there are other compounds in need of attention and regulation. All of the scientific uncertainty around climatechange relates to clouds in one way or another, said Wang’s advisor and co-author Neil Donahue, professor in chemistry.
The Creative Greenius says you can now expect a bold United States policy on cutting greenhouse gas emissions, a rapid shift away from carbon-based fuels to renewables and a science-based approach to water policy and other critical resources. Change is but mere weeks away. And again, if that bugs you - so much the better.

With climatechange awareness increasing, gas prices continuing to climb, EV charging stations expanding, and tons of new EV options hitting the market each year, it’s no surprise that electric vehicle purchases are skyrocketing. Electric vehicles are becoming more and more common on the roads across the country.
switched to a heat pump, home energy use would drop by 31 to 47 percent on average, and national carbon dioxide emissions would fall by 5 to 9 percent, depending on how much electricity is provided by renewable energy. A two-year study published 12 February in the journal Joule supports the DOE’s claim.

2021 was a big year for energy-related news, what with the ongoing hunt for new forms of energy storage and cleaner if not carbon-free electricity and events and research that spotlighted the weak links in our power grid. We’ll still have to do the hard work of cutting carbon emissions, but geoengineering could be a way to buy us some time.
Thousands of Washington insiders and climate activists have had a hand in these legislative breakthroughs. Among the most articulate and almost certainly the wonkiest is Jesse Jenkins , a professor of engineering at Princeton University, where he heads the ZERO Lab—the Zero-carbon Energy systems Research and Optimization Laboratory, that is.
