Methane emissions have a feedback on its own lifetime, serve as an ozone precursor, and reduce the production of sulphate and nitrate aerosols (and consequently indirect cloud-aerosol effects), all of which amplify its net warming effect to about 1.2 ppm, a factor of more than 200 smaller). W/m 2 for CH 4. References. Etminan, G. Myhre, E.J.
Our ozone layer serves as a lifesaving UV barrier for planet earth, functioning to absorb most of the sun’s ultraviolet radiation. At the same time, ground-level ozonepollution is extremely harmful to human health. Good Ozone’: Our Essential Sun Shield. How is Ozone Created?
Krishnan Ramamurthy, DEP Deputy Secretary for Waste, Air, Radiation and Remediation, explained it this way-- “Conventional wells [were] pretty much exempted from any permitting requirements, regulatory requirements. For the first time we are addressing those. The Preamble to the revised rulemaking says “.
Krishnan Ramamurthy, DEP Deputy Secretary for Waste, Air, Radiation and Remediation, told the EQB in order to have a complete SIP [State Implementation Plan] revision meeting the mandatory requirements of EPA, Pennsylvania must cover both conventional and unconventional oil and gas facilities sources.
Chlorofluorocarbons (CFCs) : A group of inert chemical used in many industrial and everyday processes such as our refrigerators that are not broken down at lower atmospheric levels and rise to the upper levels, destroying ozone. They are water vapor, carbon dioxide, methane, nitrous oxide, ozone, CFCs, and hydrofluorocarbons.
the UHIE occurs in metropolitan areas and “can affect communities by increasing summertime peak energy demand, air conditioning costs, airpollution and greenhouse gas emissions, heat-related illness, mortality, and water quality.”. According to the US Environmental Protection . gency (EPA). , flood-prone regions.
We breathe oxygen from the atmosphere, weather systems distribute water, and the ozone in the upper atmosphere protects us from harmful radiation. 5] Additionally, the reaction of these volatile chemicals contributes to ground-level ozone production, which, unlike ozone in the stratosphere, is hazardous to human health.
Since global and local pollutants are often byproducts of the same activities, mitigation policies for global warming emissions have the potential to simultaneously mitigate local airpollution 2. One good example of the nexus between global warming and local pollution is ground-level ozone. have a diameter of 2.5
Regardless, places with high densities of emissions, such as industrialized cities, still have airpollution problems, and these are called “non-attainment areas” because those areas fail to attain one or more NAAQS. Implementation of the Clean Air Act is a unique (from a regulatory perspective) partnership between EPA and each state.
Outdoor airpollution accounts for approximately 3.7 – 4.8 AMAP Assessment 2015: Black Carbon and Ozone as Arctic Climate Forcers.” Particulate Matter AirPollution and Cardiovascular Disease.” link] Climate & Clean Air Coalition. Health Effects of Fine Particulate AirPollution: Lines That Connect.”
