New scientific information has yielded insights, including updates to our understanding of, and ability to model, the atmosphere, and the studies of the long-term effects of radiation on affected populations have yielded new information. New studies are being published and commissioned and research gaps are being identified.
The fact that there is a natural greenhouse effect (that the atmosphere restricts the passage of infra-red (IR) radiation from the Earth’s surface to space) is easily deducible from; i) the mean temperature of the surface (around 15ºC) and, ii) knowing that the planet is normally close to radiative equilibrium.
since the 1850-1900 baseline is very clearly associated with the increases in greenhouse gases, slightly (and decreasingly) modulated by the changes in atmospheric pollution. Dessler, "Evolution of the Climate Forcing During the Two Years After the Hunga TongaHunga Ha'apai Eruption", Journal of Geophysical Research: Atmospheres , vol.
The CERES estimates of the top-of-atmosphere radiative fluxes are available from 2001 to the present. 2021) also reported on a two decade estimate of Earthshine measurements which appear to confirm a small decrease in albedo (and decrease in reflected short wave (SW) radiation). A paper last year (Goode et al., It’s unlikely(?)
Some of you will have heard of John Clauser because he was an awardee of the 2022 Nobel Prize in Physics for his role in the experimental verification of quantum entanglement. He, however, goes seriously off the rails when he estimates the impact of clouds on the radiation budget. John Clauser’s theory of climate explained.
So SSU me Like MSU trends, these records reflected a weighted average of atmospheric temperatures, and the three SSU channels progressively weight higher levels in the stratosphere, roughly centered on 30km, 40km and 45km above the surface but with quite a bit of overlap. 128, 2022. The effect is larger the further up you go.
They focused specifically on two marine CDR approaches—ocean alkalinity enhancement and biomass cultivation for carbon removal (including seaweed cultivation and sinking) —and two solar radiation management techniques—marine cloud brightening and surface albedo enhancement. Solar radiation management is distinct from CDR.
Impacts of Hunga-Tonga Hunga Ha’apai (HTHH) The eruption of HTHH in January 2022, reached 56km high in the stratosphere and increased stratospheric water vapor by ~10% while also depositing SO 2 in the stratosphere. W/m 2 over 2022-2023″ (i.e. Let us know in the comments if there are relevant papers we’ve missed.
Workers in facilities that produce and use EtO as well as people living near facilities that release it into the atmosphere are at risk of unsafe exposures even when the facilities are using the best available technologies to handle and contain it. Have I been exposed to ethylene oxide?
On December 5, 2022, scientists at Lawrence Livermore National Laboratory in California focused the power of a stadium-sized laser at a target no larger than a thimble, vaporizing it within a few billionths of a second. A bumpy road to fusion.
Their conclusion builds on work done in 2020, when a team led by Graham Harper of the University of Colorado, Boulder used photometry to observe light emitted by molecules of titanium oxide in the atmosphere of Betelgeuse. They found that whatever instigated the dimming did indeed manifest as a cold patch in the star’s atmosphere.
Research published to Frontiers in Forests and Global Change offers the most comprehensive and detailed evidence to date that forests are more important to the climate – both globally and locally – than we think due to the way in which they physically transform the atmosphere.

For example, Antarctica acts to cool our planet by reflecting solar radiation back to space by virtue of the brightness of its snow surface. The danger is that the Antarctic sea ice is starting to behave like the Arctic, with sustained loss of ocean cover and consequent absorption of solar radiation.
To put these numbers in context, DEP just issued its 2022 Oil and Gas Annual Report that said 5,416 notices of violation were issued to conventional operators during all of 2022. Click Here to read the 2022 compliance report summary. Culture Of Non-Compliance’ On December 29, 2022. Read more here. Read more here.
Guest Post by Julieta Juncosa Calahorrano , 2022-2023 Sustainability Leadership Fellow, and Ph.D. Candidate in the Department of Atmospheric Science at Colorado State University Growing up in Latin America, food was at the center of many family gatherings. Food can also mean so much more than just nutrients and vitamins to each of us.
The greenhouse effect is a popular name for the earth’s warming effect which occurs naturally when gasses in the atmosphere trap heat from the sun and prevent it from escaping back into space. 2022: What Does the Latest IPCC Report Say? Understanding Climate Change & Greenhouse Gas Emissions. C above pre-industrial levels.
Guest Post by Kathryn Moore , 2022-2023 Sustainability Leadership Fellow, and Ph.D. Cloud formation in the atmosphere requires aerosols To form a water droplet in the atmosphere, water vapor molecules, floating around as a gas, need to stick together. So how do we have clouds if water isn’t condensing?
million of their product not leaking into the atmosphere, at current natural gas prices. If the Board were to provide notice of proposed rulemaking, and an additional public comment period and public hearings, the Commonwealth would be unable to submit this rulemaking to the EPA as a SIP revision by December 16, 2022.
more than in 2022 and 569.9% DEP’s 2022 Oil and Gas Annual Report said 5,416 notices of violation were issued to conventional operators in 2022 and 4,514 violations in 2021 and in 2015, DEP issued just 1,024 violations to conventional operators. Click Here to read the 2022 compliance report summary. more than in 2015.
The opinion was requested in 2022 by the Commission of Small Island States on Climate Change and International Law, which asked ITLOS to opine on States’ obligations to address climate change under the United Nations Convention on the Law of the Sea (UNCLOS).
Posted on January 18, 2022 by Daniel C. When the history of the global shift toward a clean energy economy and a sustainable future gets written decades from now, it may well be that the COP26 Climate Change Conference will be seen as a watershed moment.
9 These changes are in part due to char, the blackened debris from burned trees, which lands on the snowpack surface and increases how much solar radiation the snowpack absorbs. Npj Climate and Atmospheric Science , 1 (1), 2. Water Resources Research , 55 (11), 9748-9764. link] Mote, P. Lettenmaier, D. Xiao, M., & Engel, R.
DEP’s inspection report contained photos of the well in the same condition dated September 3, 2022. Notices of violation were also issued for failure to restore the well site and failure to submit production and waste reports for 2020, 2021 and 2022 (Rimeer 4). On January 4, 2024 , DEP inspected the W. Allshouse, Jr.,
The energy balance of our planet , the radiation arriving and leaving, is continually monitored by a global radiation network at the surface and by dedicated satellites. And yes, also the increase in back-radiation towards the Earth surface from the CO2 greenhouse effect is a measured fact. Image: Prof.
Candidate in the Department of Chemistry at Colorado State University Earths atmosphere is one of our greatest shared resources and provides many ingredients required for life. We breathe oxygen from the atmosphere, weather systems distribute water, and the ozone in the upper atmosphere protects us from harmful radiation.
Global warming is causing there to be more cloud cover over land areas because a warmer atmosphere can essentially hold more moisture. At night, clouds absorb and re-emit heat that radiates out from Earth, which has a warming effect on temperatures. Across the United States, average minimum and maximum temperatures are 1.4°F
The 250 mg/l limit of chlorides in groundwater contamination limit DEP established for the Moody study is significant because a Penn State study released in May 2022 found water runoff from conventional oil and gas wastewater dumping on dirt and gravel roads contained from 7,550 to 10,000 mg/l of chlorides.

Highlights include: A tiny startup firm, “Make Sunsets,” launched a couple of weather balloons with a few grams of SO 2 in late 2022 from a private property in Baja California, Mexico. The current spike of news coverage spans a wide range from the serious to the silly.
“If I look at the next 50 years, next hundred years maybe, nobody will be able to set up a telescope that’s powerful enough to resolve surface features,” says Jonathan Jiang , an atmospheric scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California, who uses Earth as a laboratory to model exoplanets.
Atencio writes, “Since the mid-1940s villagers had recognized the dangers of radiation, as men pushing wheelbarrows full of waste in the Los Alamos National Laboratories (LANL) suddenly turned ashen, went home, and died. In January 2022, the Archbishop of the Archdiocese of Santa Fe, John C.
In 2022, the transportation sector was responsible for 28 percent of global warming pollution in the country. It has been estimated that globally oil processing is responsible for about 15 percent of all VOCs released into the atmosphere. which is formed in the atmosphere from precursor gases such as NOx.
For example, NASEM has published landmark reports on the health effects of exposure to low levels of ionizing radiation. This was proven by showing the health harms that can be caused by ionizing radiation disproportionately increased among these vulnerable groups after similar exposures in their counterpart peers. 2006 , NCI 1997 ).
Among the issues raised by the appellants in their original appeal were-- concerns the landfill’s operation would attract birds and interfere with the operation of the nearby Grove City Airport; that the oil and gas drilling wastes the landfill was allowed to accept presented a radiation hazard; and the landfill’s compliance history.
Riyan Farm & Gas LLC - Violations - Abandoned Well (2022) November 1, 2024 follow-up inspection of the Yahner 1 conventional well in Allegheny Township, Cambria County found the owner failed to plug this abandoned well or submit production, waste generation and well integrity reports for at least 5 years. No violations issued.
International United Nations report cautions against solar radiation management and calls for international regulations for the use of this technology. Federal Register Comment Period for the National Nature Assessment Closes March 31, 2023 In April 2022, the Biden administration announced the launch of the first-ever U.S.
The House NSF bill creates a new Science and Engineering Solutions Directorate within NSF and authorizes funding for this directorate at $1 billion in fiscal year (FY) 2022. The full Committee also approved amendments adding solar radiation management and wildfire science to the list of climate change research topics funded by the bill.
