Smoke from bushfires that spread across Australia in late 2019 and early 2020 destroyed high-altitude ozone in the Southern Hemisphere, according to a study that offers new insight into the threat posed by wildfires. Read more on E360 ?.
Bakersfield, Fresno, and Visalia are consistently ranked as cities with the worst particulate and ozone pollution , according to the American Lung Association. and ozone concentrations highlighting air quality issues in the Central Valley. Annual average PM2.5 Graphics from CalEnviroScreen 4.0
One good example of the nexus between global warming and local pollution is ground-level ozone. The 2019 explosion at the Philadelphia Energy Solutions (PES) refinery was in a unit which used hydrofluoric acid as a catalyst. To make matters worse, NOx contributes to the formation of ground-level ozone and secondary PM2.5,
Global net anthropogenic greenhouse gas emissions 1990–2019. By 2019, the largest growth in absolute emissions occurred in carbon dioxide from fossil fuels and industry. As one example, according to an analysis by Client Earth , in 2019 Chevron’s disclosed emissions amounted to 697 million tons of carbon dioxide equivalent.
Medium- and heavy-duty vehicles (MHDVs), like the big rigs on our highways and the vans that deliver our packages, make up just over 1 in 10 of the vehicles on our roads, but are responsible for over half of ozone-forming nitrogen oxide pollution and lung-damaging fine particulate pollution from on-road vehicles.
In addition, ozone depletion higher up in the stratosphere has caused a cooling high up in the atmosphere. Wm 2 over the period 1750-2019 because we have added extra greenhouse gases into Earth’s atmosphere. We humans have emitted a total of about 2390 gigatons of CO 2 over the period 1850-2019.
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 ).
After the 2014 shutdown Toledo spent $53 million to install an ozone treatment system at the city’s drinking water plant to safeguard customers from algal toxins, said Andrew McClure, the plant’s administrator. Then there is the ongoing cost of putting that equipment to work. and they have largely failed outside of tribal courts.
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. The SCAQMD is requesting stakeholder feedback on the discussion draft rule by December 6, 2019. 20, 2019). [6] Looking Forward.
As previewed in a 2019 Latham blog post , despite the warehouse sector’s limited control over the types of trucks servicing its facilities (warehouses generally do not own or operate trucking fleets), the ISR imposes obligations on warehouses to indirectly reduce trucking emissions. more stringent permitting requirements for new sources).
Simplified schematic of atmosphere-ocean-ice interactions (Zalasiewicz et al, 2019). The CPDW is thought to be affected by the shift in the westerly winds around Antarctica which have increased in recent decades due to a combination of greenhouse gas forcing and the polar ozone hole ( Miller et al, 2006 ). 132-137, 2019.
But in reality the proposed emission targets were achieved 11 years early in 2019—without the plan ever even taking effect. Research has shown that the country’s remaining coal plants are responsible for 3,800 premature deaths per year, based on 2019 data.
NO x also contributes to the formation of ozone (or “smog”), another toxic pollutant. In 2019, air pollution more broadly was responsible for about 6.7 A recent study found that more than 99 percent of the global population is exposed to unsafe levels of PM 2.5 pollution, which are particles with diameters of 2.5 micrometers or less.
Studies have also shown that fireworks can create a ‘burst’ of ozone formation, also harmful to human health. concentrations on July 4 and 5 in 2020 were, on average, 50% higher than in 2019 , likely due to the increased use of household-level fireworks during the pandemic lockdown. The graph below highlights the spike in PM2.5
The lines form a chemical fingerprint that could be used to find “biosignatures” such as oxygen or ozone. The craft maintains a constant view of our planet as it rotates, observing ozone, vegetation, cloud height and aerosols in the atmosphere. 2019 ApJL 882 L1 , reproduced by permission of the AAS).

Instead, environmentalists were mainly concerned about the ozone layer, nuclear meltdown and chemical industrial pollution, the erosion of biodiversity and population explosion. I had to wait 37 years of my life until the world finally agreed to a global climate deal with the Paris Agreement in 2015.
There arecurrently carbon standards in place for new power plants , which were set back in 2015; however, there are no standards for existing plants as neither the 2015 Clean Power Plan nor the 2019 Affordable Clean Energy Rule —both of which targeted existing facilities—remain in place.
Motor vehicle exhaust is one big source of ground-level ozone or smog, fine particulate matter, carbon monoxide and nitrogen dioxide. As of 2019, the Indego system has about 150 stations and 1,500 bikes available all over the city 365 days of the year. Don’t own a bicycle or nervous about investing in one?
She was elected an Early Career Fellow of the Society in 2019. We closed the hole in the ozone. Elise Gornish is a life member of ESA and a founder of the Ecological Restoration Section. In June, she published her first children’s book, what she believes is the first children’s book on ecological restoration. People need to know that.
Carbon dioxide emissions are the leading cause of climate change, and nitrogen oxides contribute to the formation of ground-level ozone, which affects the health of children, older people, people with lung diseases such as asthma and emphysema, and people who work or are active outdoors.
There was also the Breakthrough Listen Candidate 1 (BLC1) radio signal observed in April and May 2019 by the privately funded Breakthrough Listen project at the Berkeley Search for Extraterrestrial Intelligence (SETI) Research Center at the University of California. While the WOW!
The state funded the two studies through the 2019 Budget Act. Particulate matter harms lungs and hearts, while nitrogen oxide compounds contribute to ozone pollution and other health impacts. A second study led by UC Santa Barbara was released simultaneously.
“The commitments under the settlements will significantly reduce pollution from these companies’ operations, including volatile organic compounds that contribute to ground-level ozone, and methane, a potent greenhouse gas.” The EPA identified the alleged violations through field investigations conducted in 2018 and 2019.
She is a founding member of ESA’s Traditional Ecological Knowledge section and was a plenary speaker at the 2019 Annual Meeting. EPA – Public Meeting of the Chartered Clean Air Scientific Advisory Committee (CASAC) and CASAC Ozone Review Panel (Nov. EPA – Public Meeting of the Chartered Science Advisory Board (Nov.
2 source of methane emissions, and to end pollution from the routine flaring of associated gas, a common problem in oil fields that contributes to climate change and ozone pollution across multiple states. Advocates continue to press EPA to expand retrofit requirements for pneumatic pumps designed to pollute, which are the industry’s No.
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
US electricity sector emissions decreased 34 percent from 2005 to 2019, including an astonishing 10 percent in 2019, which is the largest year-on-year decline in history. By 2019, German household electricity prices were 45 percent higher than the European average.

In September 2019, the Trump administration’s EPA, for the first time ever, attempted to revoke California’s waiver, specifically with respect to its GHG and ZEV program. On March 14, 2022, EPA rescinded its 2019 waiver withdrawal and established a new standard for revisiting approved waiver determinations.
EPA of a 2015 rule barring replacement of ozone-depleting substances with hydrofluorocarbons (HFCs), which are powerful greenhouse gases. Circuit vacated the 2015 rule to the extent that it prohibited continued use of HFCs by companies that previously switched to HFCs from an ozone-depleting substance. In Mexichem , the D.C.

Despite the panel’s regular reports about the consequences of burning fossil fuels, between 1990 and 2019 global emissions rose 54 percent and they are still rising. degree limit of the Paris Agreement is a pipe dream unless emissions peak in the coming three years and fall by almost half from 2019 levels by 2030, the scientists said.
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. After she took office in January 2019, that pledge went out the window. But he became even more entwined with the industry after becoming AG.
In October 2019, the agency deprioritized listing the species, citing state conservation efforts.

In 2019, the Trump administration disbanded the ISAC and cut funding for the National Invasive Species Council (NISC) secretariat by 50 percent. This body will review the EPA’s scientific review of current ozone pollution standards. In 2019, the Trump administration opted to keep ozone pollution standards the same.
In 2019, the Trump administration rolled back standards put in place under the Obama administration following the 2010 BP oil catastrophe that killed 11 people and spewed oil for five months. The Trump administration ended this rule in a 2019 regulation ( see ESA Policy News, Sept.
For example, recent attention has focused on tightening the National Ambient Air Quality Standards (NAAQS) for ozone smog, which is formed by atmospheric reactions on volatile organic compounds (VOCs) and nitrogen oxides (NOx). 2019); Birckhead v. 2019); Sierra Club v. 17-1271, 2019 WL 847199 (D.C. FERC , 925 F.3d
Executive Branch The Invasive Species Advisory Committee will meet publicly March 6-8, the first time since the committee was disbanded in 2019. In 2019, NISC disbanded the ISAC when the Trump administration cut funding for the council by 50%. Congress House and Senate leadership announce committee leadership positions.
The Environmental Protection Agencys final rule (October 10, 2024) regulating ozone-depleting substances. The Environmental Protection Agencys interim final rule (November 6, 2024) on the federal Good Neighbor Plan for the 2015 Ozone National Ambient Air Quality Standards. Idaho 2019). See, e.g. , Tugaw Ranches, LLC v.
This bill passed the full House in 2019 but did not advance in the Senate. The full House similar legislation in 2019. Environmental groups sued USFWS for not protecting the less prairie chicken in 2019 and a court decision required the agency to complete a 12-month species status review for the lesser prairie chicken.
