Hace 2 días · Neil. Done and dusted is actually a very common expression. We hear it a lot at work. And usually it means something has been completed successfully, there's no more work to be done on it. Let's ...
Hace 6 días · Methane's GWP 20 of 85 means that a ton of CH 4 emitted into the atmosphere creates approximately 85 times the atmospheric warming as a ton of CO 2 over a period of 20 years. On a 100-year timescale, methane's GWP 100 is in the range of 28–34.
Hace 5 días · But if they’re dusted with black carbon, the dark coloration absorbs heat. “You can see these little particles drilling holes down into the ice. It’s just very dramatic how the black carbon can absorb sunlight and heat things up,” says Brenda Ekwurzel, director of scientific excellence at the Union of Concerned Scientists.
Hace 4 días · Stratospheric aerosol injection is a proposed method of solar geoengineering (or solar radiation modification) to reduce global warming. This would introduce aerosols into the stratosphere to create a cooling effect via global dimming and increased albedo, which occurs naturally from volcanic winter. [1]
Hace 5 días · It doesn’t stay in the atmosphere as long – only about a decade compared to centuries for carbon dioxide – but it packs an outsized punch. Methane’s ability to warm the planet is nearly 30 times greater than carbon dioxide’s over 100 years, and more than 80 times over 20 years.
Hace 1 día · air pollution, release into the atmosphere of various gases, finely divided solids, or finely dispersed liquid aerosols at rates that exceed the natural capacity of the environment to dissipate and dilute or absorb them. These substances may reach concentrations in the air that cause undesirable health, economic, or aesthetic effects.
