Titled «Initiation of Snowball Earth with volcanic sulfur aerosol emissions,» the study posits a hypothesis by two researchers from Harvard University's John A. Paulson School of Engineering and Applied Sciences (SEAS).

Not exact matches

Beyond reducing the volume of acidic particles in aerosols, cutting the sulfur emissions has also reduced the deposition of acids in lakes and waterways, noted Armistead «Ted» Russell, a Regent's Professor in Georgia Tech's School of Civil and Environmental Engineering and another of the paper's co-authors.

Researchers at NASA's Goddard Space Flight Center in Greenbelt, Maryland, are using already available satellite measurements of sulfur dioxide (SO2), a main components of volcanic emissions, along with the more recent ability to map the location and vertical profiles of volcanic aerosols.

Reducing sulfur emissions also stops the cooling impact of sulfate aerosols.

Anything above VEI 3 will likely have some effect on stratospheric aerosols, (although the amount of sulfur emissions don't correlate precisely with VEI index).

Pitari, G., E. Mancini, V. Rizi, and D. Shindell, 2002: Feedback of future climate and sulfur emission changes an stratospheric aerosols and ozone, J. Atmos.

In response, the IPCC added a cooling factor to its models of the atmosphere, consisting of tiny aerosol particles produced by the emission of sulfur dioxide from electric power plants.

I'm not sure, therefore, what is the basis for your description of a «permanent cloud of aerosols», particularly as it relates to sulfur emissions.

My question woiuld be: What happens when human related forcing such as aerosols, sulfur emission, etc. act in opposition to other human related forcing such as greenhouse gas emissions?

All of these studies find that humans are responsible for close to 100 % of the observed global warming over the past 50 years, and human greenhouse gas emissions are responsible for close to 150 % of the observed warming, with human aerosol (sulfur dioxide - SO2) emissions offsetting approximately one - third to one - half of that greenhouse warming.

The control knob for climate change is the amount of dimming sulfur dioxide aerosol emissions in the atmosphere — the fewer there are, the warmer it gets — and we are reducing them as fast as we can, thanks to the EPA.

Large aerosol optical depths due to sulfur emissions occur in Northern Hemisphere industrial regions.

Furthermore, estimating the direct and indirect aerosol effects (29) through 2008 as a residual from the Earth's energy balance (as was done for 1954 — 2000) would generate results that either support or contradict the increased importance of anthropogenic sulfur emissions discussed above.

Concentrations of sulfate aerosols were especially high during these years before regulations like the Clean Air Act limited sulfur dioxide emissions that produce sulfate aerosols.

The failure to actually reduce global emissions has meant that all possibilities are now on the table, including some that sound like premises from a science - fiction novel: Humans could sequester carbon dioxide by removing it from the air through technologies that mimic trees, or we could spray water droplets in the lower atmosphere to reflect light and heat back to space, or we could seed sulfur aerosols in the stratosphere to do the same.
