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.
are used all over the world, based on calculations that quantify the effects of physical mechanisms and the way different parts of the atmosphere are connected to each other. The physics-based models describe how energy flows through the atmosphere and ocean, as well as how the forces from different air masses push against each other.
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?
Great Dimming: Betelgeuse as observed in 2019–20 (Courtesy: ESO/M Montargès et al. ). The dramatic dimming of the red supergiant star Betelgeuse in 2019–20 was caused by a cold spot on the surface of the star causing a nearby gas cloud to cool and condense into obscuring dust, according to new findings. Clumps of gas.
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! Picking up pollution.
Question a) referred to States’ obligations to prevent, reduce and control marine pollution in relation to the deleterious effects resulting or likely to result from climate change and ocean acidification caused by anthropogenic greenhouse gas (GHG) emissions into the atmosphere.
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. C increase, the IPCC report states GHG emissions must be cut back by 43% by 2030 and 84% by 2050 (relative to 2019 levels). F), let alone 1.5°C
.” -- “Routine” Venting Of Conventional Gas Wells: DEP’s inspection reports document the fact venting natural gas to the atmosphere is a “routine” part of conventional well drilling, in spite of recently passed Air Quality regulations that limit methane emissions from conventional wells. 28 to Nov. 30 to Oct.
Student in the Department of Atmospheric Science at Colorado State University Most people remember the water cycle they learned in school: water evaporates from lakes, rivers, and the ocean, air carrying this moisture rises, cools, condenses, and forms clouds, and these clouds precipitate water back down to the surface.

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. R., & Kampf, S. Water Resources Research , 55 (11), 9748-9764. link] Mote, P. Lettenmaier, D.
2019 ) gives a good overview of Manabe’s particular philosophy of climate modeling which was very much focused on getting things to work, and not worrying too much about the details. Manabe’s Climate Modeling. Fortunately, Manabe recently wrote a retrospective on his early work in response to receiving the Crafoord prize in 2018.
Although the latter accelerate the rise of CO2 in the atmosphere, on the other hand, radiative forcing (which causes warming) increases only with the logarithm of CO2 concentration, and therefore roughly linearly since the 1970s. The first graph shows the global temperature trend. C, at least with 50:50 probability.
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.
OK, on to methane in the environment: The headline here – whether you’re talking about atmospheric concentrations, climate impacts, or emissions – is that there is a lot less methane than CO 2 , but it’s a more potent climate heater and it’s increasing faster. Atmospheric concentrations. Climate impact. W/m 2 from elevated CO 2.
“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.
It not only traps heat in the atmosphere, contributing to global warming, but the warmer temperature resulting from global warming leads to an increase in ground-level ozone, since ozone is produced indirectly from precursors like NOx and VOCs in the presence of sunlight. which is formed in the atmosphere from precursor gases such as NOx.
The previous summit, held in Madrid in 2019, ended in frustration with little progress on issues such as carbon financing or sharing climate burdens between nations. As air sunk through the atmosphere, it got squeezed and heated. Taken together, however, clouds in today’s atmosphere have an overall net cooling effect.
But if primordial black holes (PBHs) did form as early as one second after the Big Bang, during the “radiation dominated” era, things would be different. As Hawking had first realized, black holes evaporate over time, via Hawking radiation. Black holes formed much later, only after the first ancient stars had died.
People should be celebrating, not demonizing, modern increases in atmospheric carbon dioxide (CO2). In other words, the Earth came within 30 ppm in CO2’s atmospheric concentration of witnessing the extinction of most land-based plants and all higher terrestrial life-forms – nearly a true climate apocalypse.

Gleick falsely accuses me of cherry-picking a quote from a 2019 New York Times story on Amazon fires. “If That talk helped the [National Center for Atmospheric Research] scientists to see the big picture clearly and early on.” But the atmospheric equivalent of garbage dumps.” The Malthusians significantly modified Malthus.
For example, the core provision of the Tennessee law : The intentional injection, release, or dispersion, by any means, of chemicals, chemical compounds, substances, or apparatus within the borders of this state into the atmosphere with the express purpose of affecting temperature, weather, or the intensity of the sunlight is prohibited.
Perhaps you remember Sharpiegate in 2019, when then-President Trump doctored the forecast path of Hurricane Dorian with a black Sharpie maker. For instance, explaining nuclear toxicology concepts is important for helping the public understand why and how to avoid radiation exposure.
International United Nations report cautions against solar radiation management and calls for international regulations for the use of this technology. ESA joined other aquatic science societies in opposing the Trump administration’s Section 401 proposed rule in October 2019. States Washington state holds carbon allowance auction.
