Earlier observations from satellites and balloons suggest that stratospheric water vapor probably increased between 1980 and 2000, which would have enhanced the decadal rate of surface warming during the 1990s by about 30% compared to estimates ignoring this change, according to the authors. —Solomon et al.
Although viewed as a potential target in the global effort to reduce climatechange, atmospheric black carbon particles absorb significantly less sunlight than scientists have predicted, according to a new study by an international team of researchers, published in the journal Science. Earlier post.).
Mitloehner said that focusing on meat and dairy is not only scientifically inaccurate, but also distracts society from embracing effective solutions to global climatechange. It read: “ The livestock sector is a major player, responsible for 18 percent of greenhouse gas emissions measured in CO 2 e (carbon dioxide equivalents).
trillion in 2010) would be required to overcome poverty; increase food production to eradicate hunger without degrading land and water resources; and avert the climatechange catastrophe. In addition, global carbon dioxide emissions have been increasing.
EPA’s SmartWay Transport Partnership is a market-driven initiative that empowers businesses to move goods in the cleanest, most energy-efficient way possible to protect public health and reduce the emissions that contribute to climatechange. Davis Transfer Co. Cargo Transporters. Challenger Motor Freight Inc. DHL Express USA.
Prof Dabo Guan, professor of climatechange economics at the University of East Anglia (UEA), led the research, along with Dr Yuli Shan from UEA’s School of International Development. Rather than creating low-carbon pathways at a national level, we need a pathway for each city. —Prof Guan.
A study by researchers at UC Davis suggests that a properly designed vehicle scrappage (i.e., Considering the 4-6 year vehicle product planning, design, and introduction cycles where major retooling of automobile plants is needed, the researchers said, such longer term programs could actually induce technology changes. Earlier post.).
ARB staff believes that vehicle mass-reduction technologies, along with many other vehicle technologies—including powertrain efficiency, improved aerodynamics, and hybrid drivetrain systems—could be among the promising strategies for reducing carbon dioxide and other greenhouse gas emissions. ITS-Davis, 2010. EDAG, 2009.
Increasingly efficient conventional combustion-engine vehicles will be key in moving towards a low carbon future, according to the GFEI. carbon fuel vehicles will be needed to continue to decarbonize LDVs and reduce oil use out to 2050 and beyond. If the question is ‘how do we move to a low carbon future for vehicles?’,
The California Air Resources Board estimates that significant GHG reductions from passenger vehicles can be achieved through improvements in vehicle technology and the low carbon fuel standard; however, these reductions will not be enough to achieve 1990 levels if current trends in vehicle miles traveled (VMT) continue. Rodier, Caroline J.
A new study finds that the growth of carbon production from Chinese exports has slowed or reversed, reflecting a “new phase of globalization” between developing countries that could undermine international efforts to reduce emissions. 2018) “China’s “exported carbon” peak: Patterns, drivers, and implications.” —Prof Guan.
While this sounds like an all-too-logical conclusion, the study reports a 57% reduction in the benefits of driving the fuel efficient car for carbon emissions purely based on the purchase of the second vehicle.
Participating scientists are from several DOE national laboratories, NASA and the University of California, Davis, along with many other academic and research institutions. The data they are collecting will help researchers improve computer models that simulate the climate and project climatechanges.
Reducing the carbon intensity of the energy sources used in aviation and marine transportation, by transitioning to alternative fuels and power sources, also could reduce GHG emissions over the medium to long term, although the level of potential reductions is uncertain.
Organic aerosol (OA) in the atmosphere is detrimental to human health and represents a highly uncertain forcing of climatechange. The use of petroleum-derived fuels is an important source of reactive gas-phase organic carbon that provides key precursors to the formation of secondary OA (SOA) and tropospheric ozone.
Very little research has been performed applying CO 2 as the carbon source in synthetic fuel production, the authors note, because generally CO 2 —which is chemically very stable—has been thought of as having too high of an energy barrier for polymerization, even in the presence of a catalyst. Davis and Heather D. Dorner, Dennis R.
Columbia University’s Center on Global Energy Policy and the University of California, Davis Institute of Transportation Studies analyzed four scenarios to understand how COVID-19 and other political, economic, social and technological drivers may impact transportation activity and global oil demand.
The International Transport Forum (ITF) at the OECD has launched a major global initiative towards carbon-free transport. It is now up to the transport sector to demonstrate how carbon-free mobility can be achieved. Transport activity currently contributes 23% of global CO2 emissions from fossil fuels, with the share expected to rise.
Katie Davis, Trane Technologies The colder the temperature outside, the harder heat pumps must work to extract and move enough heat to maintain the home’s temperature. They couldn’t get the lab any colder than that, so we had to cut the power to get the heat pump to turn off,” Davis says.
Unlike ethanol made from grains, such fuels could be used in today’s engines and infrastructures and would be carbon-neutral, meaning the use of these fuels would not exacerbate global climatechange. Among potential crop feedstocks for advanced biofuels, switchgrass offers a number of advantages.
DOE’s National Energy Technology Laboratory (NETL), under the purview of DOE’s Office of Fossil Energy and Carbon Management (FECM), will manage the selected projects. The projects are additional selections for the $160-million funding opportunity DE-FOA-0002400, announced in January 2021. Earlier post.)
Though it’s clear that ess carbon in the atmosphere coming from tailpipe exhaust is a win for the planet, not everyone shares the belief that all-electric transportation is the panacea it is chalked up to be. Rapson, a professor at the University of California, Davis. “It Downsides to the forecasts But not all skies are sunny.
A five-year, £11million study into the effects of climatechange on Britain’s seas has been announced as scientists warn of more acidic seas affecting the food chain. Passenger cars account for about 12 per cent of the European Union’s yearly carbon emissions.
The award recognises Jaguar’s efforts in lowering carbon dioxide (CO2) emissions and fuel consumption as well as presenting advantages to customers. According to Andrew Davis, director of the ETA, the XJ “consistently outperforms its rivals in the luxury class&#. .
The program, which is essential to fulfilling the state’s pioneering climate-change policies, is slated to invest approximately $90 million during this fiscal year to develop new transportation technologies, as well as alternative and renewable fuels.
Attendees believe that renewable energy needs two elements to be successful: technical progress leading to lower costs and a price on carbon. They were hoping it was going to be more aggressive in combating carbon directly through a stronger cap and trade and indirectly with a higher federal renewable energy standard. Earlier post.).
and UC-Davis Emeritus and Catherine JJ DeMauro. He holds more than 35 patents (12 of which belong to UC Davis), has published more than 100 papers, and is an internationally recognized subject matter expert. To restore balance we must protect the oxygen-producing biomass of Earth and reduce the amount of carbon emissions.
Larry Burns, GM vice president for research and development and strategic planning: "Whether your concern is energy security, global climatechange, natural disasters, the high price of gas, the volatile pricing of a barrel of oil and the effect that unpredictability has on Wall Street - all of these issues point to a need for energy diversity.

In a call with reporters on Thursday, EPA Assistant Administrator Bill Wehrum said: There’s nothing about how greenhouse gases and potential climatechange affects California that’s any different than any other state in the country. —California Air Resources Board Chair Mary D. —The ICCT.
