Among the many climate-related vulnerabilities that can impact its mission, the US Environmental Protection Agency (EPA) cites a likely increase in tropospheric ozone pollution as potentially making it more difficult to attain National Ambient Air Quality Standards ( NAAQS ) in many areas with existing ozone problems.
Significant climate anomalies 2008/2009. Source: ClimateChange Compendium. The hole in the ozone layer has had a cooling effect on Antarctica, and is partly responsible for masking expected warming on the continent. ClimateChange Science Compendium 2009. Tags: ClimateChange. Earlier post.).
This new study is based on a thorough review of a decade of research on aviation emissions. It makes an important contribution to the scientific understanding we have of the role of aviation for climatechange—an understanding decision-makers and politicians may need on the way to achieving the goals of the Paris Agreement.
the final version of the proposed First Update to the ClimateChange Scoping Plan (First Update). Achieving our long-term climate goal and 2032 ozone standards will require a much deeper penetration of ZEVs into the fleet. The California Air Resources Board (ARB) has released. The draft version was released in February.
The system will graph lifecycle impact for a range of specified powertrains, for a large number of impact categories: Climatechange [kg CO 2 -eq.]. Deterioration of the ozone layer [kg CFC-11-eq.]. The top sample above shows climatechange impact; the subsequent chart shows human toxicity. in review).
The study will appear next month in the peer-reviewed journal ClimaticChange Letters. Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. However, the effects of natural gas on climatechange have been difficult to calculate.
After a thorough scientific review ordered in 2007 by the US Supreme Court, the US Environmental Protection Agency (EPA) issued a proposal with two distinct findings regarding greenhouse gases. In both magnitude and probability, climatechange is an enormous problem. harm to water resources, agriculture, wildlife and ecosystems.
US Congressman Scott Peters (CA-52) introduced the Super Pollutant Emissions Reduction Act (SUPER Act) of 2013, legislation aimed at combating short-lived climate pollutants, which are only somewhat addressed by disparate government programs. C in projected cumulative warming by 2050 and 1.1 °C C or more projected warming by 2100, IGSD says.
Decomposition of the decadal change in total global CO 2 emissions from fossil fuel combustion by four driving factors; population, income (GDP) per capita, energy intensity of GDP and carbon intensity of energy. However, the underlying estimates do not take into account economic benefits of reduced climatechange.
On the first day of a two-day board meeting—the second day of which (Friday 24 March) will consider the Advanced Clean Cars Midterm Review—the California Air Resources Board (ARB) took a number of climate and air quality actions. emissions by more than 20%. emissions by more than 20%.
That figure does not include damages from climatechange, harm to ecosystems, effects of some air pollutants such as mercury, and risks to national security, which the report examines but does not monetize. The resulting consensus reports undergo external peer review before completion. Source: “Hidden Costs of Energy”.
The draft adds HFCs to the list of similar substances that EPA currently regulates because they deplete the ozone layer. The draft also provides that new source review does not apply to these global warming pollutants. Tags: ClimateChange Emissions Policy. Ensuring Domestic Competitiveness.
The leaders of the world have just returned from the UN's latest climatechange summit, COP26 , in which the countries that have signed on to the Paris Agreement upped their commitments to fight climatechange. IEEE Spectrum : What role does Silver Lining play in climate research or advocacy? In 2015, the U.S.
The estimated climate benefits reflect a net reduction in climatechange damages, which include human health impacts, property damages from flood risk, and the value of ecosystem services, among other effects.
ARB staff reviewed four offset protocols and recommends that they be approved as part of this regulatory package: (1) the Urban Forest Projects Protocol; (2) the US Ozone Depleting Substances Projects Protocol; (3) the Livestock Manure (Digester) Projects Protocol; and (4) the US Forest Projects Protocol. Offset Protocols.
As we confront the enormous challenge of climatechange, we should take inspiration from even the most unlikely sources. Take, for example, the tens of thousands of fossil-fueled ships that chug across the ocean, spewing plumes of pollutants that contribute to acid rain, ozone depletion, respiratory ailments, and global warming.
After a thorough scientific review was ordered by the US Supreme Court in 2007, the Environmental Protection Agency (EPA) has issued a proposal on greenhouse gases. It has been deemed by the EPA that the emissions from new motor vehicles and their engines contribute to these concentrations and threaten climatechange.
Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new work led by the National Center for Atmospheric Research (NCAR). The RCPs were chosen to represent a broad range of climate outcomes, based on a literature review. Ozone formation.
New WHO has issued new Global Air Quality Guidelines (AQGs) that reduce levels of key air pollutants, some of which also contribute to climatechange. When action is taken on these classical pollutants—particulate matter (PM), ozone (O?), and PM 10 ), ozone, nitrogen dioxide, sulfur dioxide and carbon monoxide.
A new report prepared by the World Bank at the request of the G8 identifies ways that the World Bank can do more through its projects to reduce the emission of short-lived climate pollutants (SLCPs): black carbon, methane, tropospheric ozone, and fluorinated gases known as HFCs. Over the six-year period of the review (FY2007-2012), 7.7
Many of the strategies employed to reduce GHG emissions will also work to meet the national ambient air quality standard for ozone in 2032. However, to achieve the needed transportation GHG reductions and the corresponding 2032 ozone standards, the market uptake of advanced technologies will need to be accelerated. Vehicle technology.
In their paper on lifecycle analysis, Emanuela Menichetti and Martina Otto reviewed and assessed 30 LCA studies particularly those relating to the energy balance and greenhouse gas (GHG) emissions of biofuels produced from a range of crops and other biomass feedstocks using various conversion technologies. Lifecycle analysis. Howarth, R.W.,
Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather? Research takes a long time.
