Illustration of projected ozone changes in the South Coast region due to climate change in 2050. Areas in orange and red could see ozone concentrations elevated by 9 to 18 parts per billion. We already know that climate change will bring us increased forest fires, shorter winters, hotter summers and impact our water supply.
The amount of greenhouse gases in the atmosphere reached a new high in 2010 since pre-industrial time and the rate of increase has accelerated, according to the World Meteorological Organization’s (WMO) Greenhouse Gas Bulletin. Between 2009 and 2010, its atmospheric abundance increased by 2.3 parts per million) and the past decade (2.0
Lisa P Jackson, Administrator of the US Environmental Protection Agency, issued a public memo to EPA employees detaling “ seven key themes to focus the work of our agency ” in 2010 and beyond. Protecting America’s Waters. The seven themes are: Taking Action on Climate Change. Improving Air Quality. Cleaning Up Communities.
In addition to studying the important issues at the nexus of the air quality and climate change problems, the goal of CalNex 2010 is also to provide scientific information regarding the trade-offs faced by decision makers when addressing these two inter-related issues. 2010 CalNex Science and Implementation Plan. emission inventories?
Researchers at North Carolina State University are developing an ozone-based pre-treatment technique (ozonolysis) to release sugars from the energy grass miscanthus for production into renewable fuels or chemicals with minimal generation of chemical waste streams and degradation of the carbohydrate components. García-Cubero et al.
The process was presented during the 90 th Springtime Annual Meeting of The Chemical Society of Japan (CSJ), 26-29 March, 2010. Unlike other ethers, DME does not form peroxides, is non-toxic, has no effect on global warming nor ozone depletion and can be considered an environmentally friendly solvent.
Data collected during a major 2010 state-federal atmospheric research project show that the first-in-the-nation regulation requiring ocean-going vessels to use clean fuel when near the California coast has been extremely effective in reducing sulfur dioxide pollution from ships, according to the California Air Resources Board (ARB).
This could explain satellite measurements showing high levels of stratospheric ozone, water vapor and other chemicals over Asia during summer. When sulfur rises into the stratosphere, it can lead to the creation of small particles called aerosols that are known to influence the ozone layer. Science doi: 10.1126/science.1182274.
An international team of scientists who monitor the rapid changes in the Earth’s northern polar region say that the Arctic is entering a new state, one with warmer air and water temperatures, less summer sea ice and snow cover, and a changed ocean chemistry. C) greater than the 1981-2010 baseline period.
NO x is a precursor for both ground level ozone and secondary PM 2.5 The main conclusions of the report include: Compared to emission controls on MY 2010 US diesel trucks, today’s compact aftertreatment systems are 40% lighter, 60% smaller, and substantially less expensive.
This is especially the case for those draining nitrogen-enriched urbanized and agricultural watersheds, highlighting the importance of managing nitrogen before it reaches open water. Nitrous oxide is a potent greenhouse gas that contributes to climate change and stratospheric ozone destruction. Beaulieu et al. PNAS doi: 10.1073/pnas.1011464108.
The figure includes the direct effects and those indirect effects due to the production of tropospheric ozone and stratospheric water vapor.) Overall, EPA reported a slightly less than 1% drop in methane (CH 4 ) emissions from 2010 to 2011 (from 592.7 12.6%) decrease under 2010 emission levels. Tg CO 2 eq) in 2011.
60% of ground-level ozone (O 3 ) precursors, 6% of fine particulate matter (PM 2.5 ), and 22% of greenhouse gases (GHGs) emitted. Efficiencies and emissions factors reported are for year 2010. They excluded emissions occurring outside of the contiguous US and surrounding waters) from the results below.
As of 2010, biofuel production was contingent on subsidies, tax credits, the import tariff, loan guarantees, RFS2, and similar policies. Biofuels production has been shown to have both positive and negative effects on water quality, soil, and biodiversity. Barriers and opportunities.
A 220 volt socket like on your water heater or dryer would be better, ad these typically have 40 or 50 amp circuits, so they can deliver 8,000 to 10,000 watts - is this what they mean? 110 charging for home is probably ok, because youre going to charge over night, but for charge stations it just wont be enough.
The update identifies eight key sectors for ongoing action: Energy; Transportation, fuels, land use and infrastructure; Agriculture; Water; Waste management; Natural lands; Short-Lived Climate Pollutants (such as methane and black carbon); and Green Buildings. Transportation.
