Scientists are sounding the alarm because this warming is shockingly bigbigger than what we would have expected given the long-term warming trend from fossilfuel-caused climate change. Albedo is the total reflection of incoming solar radiation by Earth. But why were 2023 and 2024 so warm? What is albedo?
Climate models are the main tool climate scientists use to predict how Earth will respond to more heat-trapping pollutants in the atmosphere. Just by looking at the name, you can see that a GCM is a model that simulates the circulation of Earths different physical systems like the atmosphere and ocean. What causes a circulation?
Four RCP scenarios describe different levels of radiative forcing in the atmosphere by 2100. Radiative forcing is the change in energy balance in the Earths atmosphere due to heat trapping emissions. SSP5: Taking the highway A scenario driven by economic growth and high fossilfuel use, leading to rapid warming.
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.
But methane’s role in atmospheric chemistry and as a source of stratospheric water vapour means that it has a bigger effect on climate than just the direct effect of its concentration. There is also a very small impact of the CH 4 oxidation to CO 2 itself for any fossil-fuel derived methane. (a) W/m 2 for CH 4. Etminan, G.
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.
If people everywhere stopped burning fossilfuels tomorrow, stored heat would still continue to warm the atmosphere. Picture how a radiator heats a home. Water is heated by a boiler, and the hot water circulates through pipes and radiators in … Continue reading How fast can we stop Earth from warming?
If people everywhere stopped burning fossilfuels tomorrow, stored heat would still continue to warm the atmosphere. Picture how a radiator heats a home. Water is heated by a boiler, and the hot water circulates through pipes and radiators in the house. The radiators warm up and heat the air in the room.
I hope we can collectively reckon with another terrifyingly awesome atmospheric event: the hottest year. The NASA account continued that “any significant change in the amount of solar radiation reaching Earth can change the climate” though it stopped short of naming humans— and a few handfuls of large corporate emitters —as the culprit.
The Altiplano plateau in western Bolivia has some of the world’s highest and most consistent levels of solar radiation, creating a high potential for solar photovoltaic power in the region, but structural challenges may prevent scaling.

The ocean has already absorbed 90% of the heat trapped by greenhouse gases and 26% of the carbon dioxide emitted by humans burning fossilfuels. Commercial shipping’s reliance on energy-dense but dirty fossilfuels generates approximately one billion metric tonnes of GHGs every year, as well as black carbon and soot.
While the main focus has been on operational activities in Antarctica, global warming caused by fossil-fuel burning by these (and other) countries has left Antarctica on the brink of irreversible change. The world’s largest ever heatwave (38.5C In the Arctic this has led to regional warming four times faster than the global average.
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. Based on the lifetime of currently operating fossilfuel power plants and planned plants, it is highly likely global warming will exceed 1.5°C
billion to help South Africa shift from its current dependence on fossilfuels for power generation toward a clean and renewable electricity system. billion to help South Africa shift from its current dependence on fossilfuels for power generation toward a clean and renewable electricity system.
Steele, Executive Director The CNX report displays an astonishing number of misleading statements, questionable methodologies, and premature conclusions that, unfortunately, only serve to further undermine the health of frontline communities faced with pollution from fossilfuel extraction.
It results in this dangerous radioactive wastewater that the fossilfuel industry cannot recycle or dispose of in a benign manner. Using the wastewater for dust control and deicing of roads is another disposal method that introduces radiation and other dangerous elements into our environment. Fracking needs to stop!”
Air emissions : Any gas emitted into the atmosphere from industrial or commercial activity. 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.
Changes from the early 19 th century that led to the Industrial Revolution were based, in part, on the advanced in engineering that was fueled by advances in physics. Finally, physics can be used to calculate the amount of energy produced by the processing and burning of biofuel just as it has for fossilfuels. Particle Physics.
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. ppm, but that level is about 2.6 Climate impact.
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.
Albedo The amount of solar radiation reflected from an object or surface, often expressed as a percentage. Atmosphere The gaseous envelope surrounding the Earth. The dry atmosphere consists almost entirely of nitrogen (78.1% The dry atmosphere consists almost entirely of nitrogen (78.1%
The fossilfuel industry has systematically contaminated our environment with a wide range of toxic chemicals for over a century. It has been estimated that globally oil processing is responsible for about 15 percent of all VOCs released into the atmosphere. A study has shown that PM2.5
The correlation had been shown in a paper by an author outside the conventional scientific community, so, for good measure, Simpson added that a non-expert could not properly appreciate how atmospheric circulation affects the absorption of radiation. These results were not initially well received.
That talk helped the [National Center for Atmospheric Research] scientists to see the big picture clearly and early on.” I show how Malthusians have used climate change to shift from claiming fossilfuels were scarce to claiming that the environment was scarce. The Malthusians significantly modified Malthus.
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.

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.
PennHills Resources LLC - New Conventional Well Venting Gas November 14, 2024 routine inspection of WT 2676 6 conventional gas well in Sergeant Township, McKean County found the newly completed well venting gas to the atmosphere [a normal procedure]. No violations issued. Owner holds 1,771 oil and gas well permits. DEP inspection report.
International United Nations report cautions against solar radiation management and calls for international regulations for the use of this technology. Executive Branch USFWS proposes listing two populations of California spotted owl under the Endangered Species Act. States Washington state holds carbon allowance auction.
Holding high-level positions in the Office of Air and Radiation are Abigale Tardif and Alex Dominguez. Aaron Szabo has been nominated to be assistant secretary for Air and Radiation. The obvious goal is to plunder more public land and water for private profit for the fossilfuel and mining industries.
