The radiative forcing from these changes in concentrations can be easily calculated using standard formulas (from Etminan et al, 2016 which supersede the slightly simpler ones from IPCC TAR), as about 2 W/m 2 for the CO 2 change and 0.65 W/m 2 for CH 4. W/m<sup>2</sup> (to about 60% of the CO 2 effect since 1750).
EPA’s own scientists concluded in 2016 that the risk value of ethylene oxide is 60 times more toxic than previously understood. You can compare this to ozone which has a half-life on the order of minutes, and some PFAS chemicals that have a half-life in air on the order of several years.
I think in hindsight that my concerns from 2013 to some extent were supported by the fact that the IPCC organised an Expert Meeting on Communication, Oslo, Norway, 9–10 February 2016. In addition, ozone depletion higher up in the stratosphere has caused a cooling high up in the atmosphere.
The rule includes a sunset date, whereby the WPCO requirement expires after both an EPA finding that all SCAQMD air basins have attained the federal 2015 ozone standard of 70 parts per billion (ppb) and a CARB finding that all SCAQMD air basins have attained the state ozone standard of 70 ppb. Further Actions.
The proposed rule would provide de minimus air quality benefits in downwind areas with extremely high costs – estimated by EPA at $22 billion discounted 2016 dollars for the 2023-2042 period. The agency’s air quality modeling indicates that most areas would receive an ozone reduction of less than 0.1 ppb by 2025.
The Basin does not meet the state or federal ambient air quality standards for ozone and particulate matter, and existing regulations have to date proved insufficient to bring the Basin into compliance. According to the 2016 AQMP, mobile sources contributed about 88% of total NO x emissions in the Basin in 2012.
This is replacing the traditional hydrofluorocarbons which have been found to damage the ozone layer. Total greenhouse gas emissions could reach 1.028 million tonnes of CO2 equivalent throughout the preparation and post-Beijing Games in 2016-2022, and about a third less than the 1.6
Two steps forward, one step back: In February 2016, the Supreme Court issued a. Equally exciting, in August 2016, the Seventh Circuit Court of Appeals upheld agencies’ ability under the Energy Policy and Conservation Act to include the. stay on implementation. of the Plan, pending judicial review. social cost of carbon. formally join.
NASA satellites have been collecting data for years on nitrogen dioxide, ozone, particulate matter, and sulfur dioxide. As a result, the EPA used satellite data in their public report on clean air trends for the first time in 2016,” says Holloway. Photo courtesy of NASA Image Library .
One good example of the nexus between global warming and local pollution is ground-level ozone. To make matters worse, NOx contributes to the formation of ground-level ozone and secondary PM2.5, In 2016 it accounted for 57% of total toxic emissions from larger sources in the city, including benzene and other known carcinogens.
Despite these claims, burning waste coal is still just burning fossil fuel and results in the emissions of significant amounts of air pollution including ozone precursors, fine particulates, acid gasses, heavy metals, and vast amounts of carbon pollution. The next logical question is why is there such an excess of flared gas?

that by 2016 the rule would save up to 11,000 lives due to premature deaths and provide up to $90 billion in health benefits associated with meeting the new standards for air toxics. where the Court held that EPA could not consider cost when setting air quality standards for ozone and particulate matter. ninety percent.
The district court ruled that EPA was required to conduct such evaluations in October 2016 and set an expedited schedule for EPA’s compliance. 451962/2016 (N.Y. The standards and guidelines were published on August 29, 2016. The court indicated that the attorney general had broad power to propound the interrogatories.
For some parts of the spectrum, the IR can be either absorbed by CO 2 or by water vapour or by clouds, but taking those overlaps into account we find that 50% of the greenhouse effect is from water vapour, 25% from clouds, and about 20% from CO 2 and the rest absorbed by ozone, aerosols, and other trace gases ( Schmidt et al, 2010 ).
The Department of Environmental Protection published notice in the April 27 PA Bulletin inviting public comments on a proposed declaration of an Exceptional Air Quality Event due to 2023 wildfires from Canada and New Jersey causing elevated levels of nitrogen oxides and volatile organic compounds impacting ozone pollution in Pennsylvania.
The last Exceptional Air Quality Event DEP documented was in November 2017 related to elevated ozone pollution concentrations originating from the upper Midwest in May 2016 that impacted ozone pollution readings in Pennsylvania. Click Here for a copy of the analysis. Comments are due March 17.
EPA regulations under the Clean Air Act for controlling mercury, sulfur dioxide, ozone and other pollutants have contributed to the employment decline. Job losses have accelerated since 2012 with the development of low-cost fracking for natural gas.

Antarctic ozone hole shrinks slightly – The Hill. EPA – Public Meeting of the Chartered Clean Air Scientific Advisory Committee (CASAC) and CASAC Ozone Review Panel (Nov. In the final rule , the US Fish and Wildlife Service determines that climate change is the biggest threat to the species’ continued survival. .
NOx and VOCs mix in the presence of sunlight to form ground level ozone (smog). Exposure to shale gas air pollution and resulting ground level ozone may impair lung function and trigger asthma attacks. -- In a case-control study conducted by Rasmussen et al.
An objection to that regulation was raised by the Republicans on the House Environmental Resources and Energy Committee questioning whether the regulation met the requirements of a 2016 law (Act 52) requiring separate regulations for conventional oil and gas operations. Read more here.

Read more here. The Preamble to the revised rulemaking says “.
The letter also said, EPA “rescinds the offset sanctions which took effect on June 16, 2022 as a result of EPA’s November 16, 2020 Finding of Failure to Submit (FFS) (85 FR 72963), which found that Pennsylvania failed to submit a SIP revision addressing the 2016 Oil & Gas CTG for the 2008 ozone NAAQS.”
with definite commitments for either work or postdoctoral training increased to 70%, from 62% in 2016 — the last time NSF reported these numbers. in 2016 to 30.2% EPA – Public Meeting of the Chartered Clean Air Scientific Advisory Committee (CASAC) and CASAC Ozone Review Panel (Nov. Similarly, the number of life sciences Ph.D.
In 2016, similar figures suggested anything between 2,000 and 3,000 although the official figure was 1,800 (27). Also, with many species going extinct in the industrial age and many more threatened with extinction to the extent that there soon became an official list (16) , conservation won out with the same elements of preservation.
the Department will develop a separate rulemaking for the RACT requirements for sources of VOC emissions installed at conventional well sites” since the regulations covering oil and gas facilities are being promulgated to attain both the federal 2008 and 2015 ozone standard. The Preamble to the revised rulemaking says “. Read more here.
Where, at the beginning, there was really only one input parameter (the CO 2 concentration) that needed to be coordinated, the inputs have now broadened to include myriad forcings related to other greenhouse gases, air pollution, land surface change, ozone, the sun, volcanoes, irrigation, meltwater etc. What can be done?
These include known cancer-causing toxics like benzene, VOCs that increase ozone levels, and methane. Rising temperatures not only pose the threat of heat illness and death during heat waves, but also directly contribute to worsening ozone levels. The medical and scientific literature is clear – living within 0.5
There have been no comprehensive changes in Oil and Gas Program regulations covering unconventional shale gas development in seven years-- since 2016-- and no comprehensive update in conventional oil and gas industry regulations in 36 years-- since 1987. Read more here.
Between 1980 and 2018, US carbon monoxide levels decreased by 83 percent, lead by 99 percent, nitrogen dioxide by 61 percent, ozone by 31 percent, and sulfur dioxide by 91 percent. In addition, scientists estimate that Japan’s nuclear plant closures resulted in more than four thousand (avoidable) air pollution deaths per year.
Methane also contributes to the formation of ground-level ozone which is itself a heat-trapping greenhouse gas and, when inhaled by humans, can trigger a variety of health problems from throat irritation and coughing to bronchitis, asthma, and reduced lung function. That request was withdrawn by the Trump administration in March 2017.
The Obama Administration set the first vehicle GHG emissions standards in 2010 for vehicles manufactured in model years 2012 through 2016, and set revised standards in 2012 for model years 2017 through 2025. In many of the states challenging EPA’s emissions regulations, local governments are leading the fight against climate change.
In 2015, when he took office as AG after stints in the Texas Legislature, he sued the Environmental Protection Agency for strengthening a standard for ground-level ozone, better known as smog. Nevertheless, Jeff Landry—Louisiana’s AG since January 2016—seems more interested in defending the fossil fuel industry than his constituents.
EPA : A draft policy assessment for the reconsideration of current Ozone air quality standards finds that there is insufficient scientific evidence that there would be a public health benefit to stricter ozone regulations. The percentage of American adults with great confidence in scientists increased between 2016 and 2020.
Lawmakers have introduced different versions of this bill since 2016 but have struggled to agree on a funding source for the bill. This bill provides $1.4 billion in annual mandatory funding to state and tribal fish and wildlife agencies for the conservation of at-risk species and the implementation of state wildlife action plans.
The grant program ended in 2016 due to a lack of funding. The SAB Staff Office is especially interested in scientists with the expertise described above who have knowledge and experience relating to criteria pollutants (carbon monoxide, lead, nitrogen oxides, ozone, particulate matter and sulfur oxides). 1144 ) from by Rep.
Climate: The Environmental Protection Agency released its Climate Change Indicators report for the first time since 2016. EPA – 2021 Annual Joint Meeting of the Ozone Transport Commission and the Mid-Atlantic Northeast Visibility Union (June 15). These indicators inform the National Climate Assessment.
