These underestimate the global cooling effects of aerosol pollution, so also underestimate sensitivity.
India, another huge source of atmospheric pollution, recently allowed European scientists to measure its high - level aerosols, an experiment that also includes flights into Nepal and Bangladesh.
«It was not only a mix of desert aerosol and pollution but there were also surface and column measurements.
Indeed, conventional wisdom held that higher levels of aerosol pollution in the atmosphere should cool the earth's climate because aerosols can increase cloudiness; they not only reduce precipitation, which raises the water content in clouds, but they also increase the size of the individual water droplets, which in turn causes more warming sunlight to be reflected back into space.
According to a report that used INDOEX data and was published last month in Science, aerosols from man - made pollution may also play a role in weakening the planet's water supply.
So, although aerosols may make a sunset red, excess pollution will also dampen the overall sunset experience.
The high levels of aerosol pollution to be found in many regions of Asia up to and including the present day are well documented: see https://www.economist.com/blogs/economist-explains/2018/01/economist-explains-19 and also https://www.vox.com/energy-and-environment/2017/11/22/16666808/india-air-pollution-new-delhi
From sheer thermal inertia of the oceans, but also because if you close down all coal power stations etc., aerosol pollution in the atmosphere, which has a sizeable cooling effect, will go way down, while CO2 stays high.
However, they are also still mapping out the association between pollution, climate and weather, and one particular concern is that injecting aerosol into the atmosphere without a thorough understanding of the process might just make things worse.
[*) The temperature plateau between 1998 and 2008 would not just be ENSO, but also due to increased sulphur aerosol pollution in China.]
«since the mid 1980s a significant increase in visibility has been noted in western Europe (e.g. Doyle and Dorling, 2002), and there are strong indications that a reduction in aerosol load from anthropogenic emissions (in other words, air pollution) has been the dominant contributor to this effect, which is also referred to as «brightening».»
However — a group of scientists of the US Department of Energy Pacific Northwest National Laboratory, the University of Maryland and the Hebrew University of Jerusalem now say that aerosol pollution does not necessarily lead to (low - lying) stratus clouds one would appreciate for climatic cooling, but that it can also be a factor in the creation of thunderstorm clouds, clouds that have a complicated climate effect, but that are suspected of being net warmers.
I'll let John Philips dig up the studies but just to add a little more explanation: It is not only that the sulfate aerosol pollution from First World countries started to decrease, it also has to do with the different residence time of CO2 and of sulfate aerosols in the atmosphere.
He also found that much of the effect was due to natural aerosols which would not be affected by human activities, so the cooling effect of changes in industrial pollution would be much less than he had calculated.
Among the issues discussed: solar energy variations that could contribute to the ebb and flow of ice ages, new understanding of ice ages and the possibility of cooling because of aerosol pollution, but also the possible confounding factor of increasing greenhouse gases:
So the cooling back then wasn't only down to increased industrial aerosol pollution blocking / scattering some of the incoming sunlight, the IPO also played a part.
Ramanathan and Feng gave a figure greater than 2 degrees for this zero emissions scenario, but they also zeroed out aerosol pollution too.
Warming from decade to decade can also be affected by human factors such as variations in the emissions, from coal - fired power plants and other pollution sources, of greenhouse gases and of aerosols (airborne particles that can have both warming and cooling effects).
His characterization of the aerosol as pollution has also been used here and elsewhere in articles, blogs, etc..
We also emit conventional pollution, causing black soot and aerosols that have differing (and debated) effects on climate.
