Sentences with phrase «sulphur aerosols»
"Sulphur aerosols" refers to tiny particles made up of sulphur that are suspended in the air. These particles can come from various sources such as volcanic eruptions, industrial emissions, or burning fossil fuels. They can have both natural and human-made origins. These aerosols can affect our climate, as they can reflect sunlight and potentially cool the Earth's surface. Full definition
Between 1968 and 1972... the surface temperature of oceans in the northern hemisphere plummeted by 0.3 C...... Researchers had thought that the drop was due to the build - up of sulphur aerosols in the atmosphere from fossil fuel burning.

Both explained that CO2 levels were rising and that one would assume this to lead to higher temperatures, but that this seemed to be cancelled out because the ocean took up so much of our emissions and because of human sulphur aerosols off - setting the warming.
[*) The temperature plateau between 1998 and 2008 would not just be ENSO, but also due to increased sulphur aerosol pollution in China.]
As noted above, some air pollutants, such as sulphur aerosol, have a significant effect on the climate system, although considerable uncertainties still surround the estimates of anthropogenic aerosol emissions.
If we account for the cooling effect of sulphur aerosols from industrial pollution, greenhouse gases have already contributed 2 ℃ of global warming.
The research does seem to confirm the cooling potential of sulphur aerosols and associated forms of SRM geoengineering.
«Climatologists tend to fall into two camps: there are the cautious ones who say we need to cut emissions and won't even think about high global temperatures; and there are the ones who tell us to run for the hills because we're all doomed» and that sulphur aerosols are being reconsidered by the British Government again as a sun shield.
Sulphur aerosols can remain airborn for months to several years, during which time they lower the average albedo and thus reflect sunlight back to the cosmos.
