We collaborated with researchers from Colorado State University, Ajax Analytics, and the Colorado School of Public Health to study the cumulative risks posed by volatile organic compounds (VOCs) and ozone to communities living along Colorados Front Range.
Other approaches involve greater risk, like genetic engineering of plants to increase their carbon absorption or changing ocean chemistry to do so. On the positive side, the National Academy of Sciences says solar geoengineering “ could reduce surface temperatures and potentially ameliorate some risks posed by climatechange (e.g.,
A new paper by Ben Santer and colleagues has appeared in PNAS where they extend their previous work on the detection and attribution of anthropogenic climatechange to include the upper stratosphere, using observations from the Stratospheric Sounding Units (SSUs) (and their successors, the AMSU instruments) that have flown since 1979.
By Bob Berwyn After sampling the atmosphere above the Arctic for more than a year during the MOSAiC research voyage , climate scientists say the ozone layer, Earth’s protection against intense ultraviolet radiation, is at risk, despite the progress made in protecting atmospheric ozone by the 1987 Montreal Protocol , the global treaty that banned ozone-harming (..)
Without the Montreal Protocol, more solar radiation would have destroyed plants, lessening the CO2 they absorb. -- Read more on ScientificAmerican.com.
For example, EPA rules limiting ozone pollution or carbon from power plants move the first lever, while the combined $1.25 EPA’s Climate Pollution Reduction Grants (CPRG) On September 20, 2023, EPA announced the Climate Pollution Reduction Grants (CPRG). Administered by the Office of Air and Radiation, this program is $4.6
Recent science doesn’t support this optimism, as new studies show that the increased release of Black Carbon, one of the most potent climatechange forcers—as well as soot, carbon dioxide, methane and ozone from more traffic in the Arctic—could lead to a 20% increase in the global heating that is causing warmer ocean temperatures.
Summary: Green-roof zoning laws may provide a solution to the Urban Heat Island Effect, which contributes to anthropogenic climatechange through heat pollution originating from large cities. Green-roofs are an overlooked solution to the complex problem of heat pollution, which contributes to anthropogenic climatechange.
But since it became clear that human actions are damaging the environment and changing the climate, it has become much more prominent nationally and internationally with most government departments in most countries having responsibilities to mitigate or prepare for climatechange scenario. The Human Impacts on Climate.
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. Climatechange : The process by which the climatechanges due to “forcings”.
Albedo The amount of solar radiation reflected from an object or surface, often expressed as a percentage. volume mixing ratio), together with a number of trace gases, such as argon (0.93% volume mixing ratio), helium, radiatively active greenhouse gases such as carbon dioxide (0.035% volume mixing ratio), and ozone. See, Weather.
GHG Emissions by Sector Climatechanges pollution and pollution changesclimate Another reason to look at the global warming impacts of refineries from a health perspective is that there is an important link between global warming and local pollution. See the pie charts below. Secondary PM2.5
There are only 6 NAAQS - ozone, carbon monoxide, particulates, lead, sulfur dioxides, and nitrogen dioxides - but they dominate most air quality concerns ranging from smog to health effects, such as from particulates and lead. There remain some problem areas; for example Boston tends to be a non-attainment area for ozone in the summer.
(Figure 1) These properties are a double-edged sword: while they are the root of the problems that black carbon causes, they also make mitigating black carbon one of the most actionable ways to fight climatechange. AMAP Assessment 2015: Black Carbon and Ozone as Arctic Climate Forcers.” Arctic Council. June 25, 2020.
In the last few months he has given two interviews in which he goes into to detail about what he describes as a ‘missing element’ in climate science and what he imagines the consequences are for climatechange. The second was a podcast with the somewhat troubled Chris Smith , an Australian journalist. .
