Sentences with phrase «industrial aerosol cooling»

Regardless of the cause, which some have attempted to explain as due to industrial aerosol cooling, one can't accuse CO2 emissions of raising global temperatures during a period when there was no such rise.

runup from 1910 - 1940 than lack of volcanic activity and a better explanation for the 1940 - 1979 hiatus than industrial aerosol cooling.»

Not exact matches

Now if this was the 1980s they might have had a point, but the fact that aerosols are an important climate forcing, have a net cooling effect on climate and, in part, arise from the same industrial activities that produce greenhouse gases, has been part of mainstream science for 30 years.

You can, of course, argue that other factors were at work in the early 20th century warming phase, but if you want to argue that the mid-century cooling was largely due to the neutralizing effect of industrial aerosol pollutants, then you can not, as did Rodgers, claim that any part of that earlier warmup was due to the burning of fossil fuels.

«A rapid cutback in greenhouse gas emissions could speed up global warming... because current global warming is offset by global dimming — the 2 - 3ºC of cooling cause by industrial pollution, known to scientists as aerosol particles, in the atmosphere.»

On the one hand it repeats the oft argued claim that the cooling after 1940 was largely due to sulfate aerosols produced by «industrial activities,» but on the other hand, she is honest enough to admit that «the situation is complicated» by factors rarely addressed by cli - change advocates:

Further, since these industrial pollution centers have had widespread aerosol thermal changes, the localized effects would have shown «hotbeds» of cooling (sorry).

Lastly, today, i.e. over the last 30 years, we should be able to observe the identical localized aerosol caused cooling over the Chinese industrial zones, which are known for their constant brown haze.

Industrial - produced cooling aerosols, without which most climate models can't be made to fit history, are another example.

lends support to the idea that a period of global cooling occurred later during the mid-twentieth century as a result of sulphate aerosols being released during the 1950s with the rise of industrial output.

The localized cooling between about 1950 and 1970 over industrial regions such as Europe and Southeast Asia, where anthropogenic sulfate aerosol loadings were high, is consistent with the expected cooling effect of sulfate aerosols.

Similar considerations apply to non-chaotic anthropogenic cooling phenomena such as industrial aerosols, anthropogenic cooling catastrophes (global thermonuclear war), or non-anthropogenic catastrophes such as an asteroid impact.

It turns out that these supposedly - cooling aerosols are produced mainly in the northern hemisphere, where industrial activity is highest.

That stagnation or slight cooling in the 70's is entirely due to aerosols, both volcanic and industrial.

From the IPCC AR4 report, FAQ2.1, Figure 2, the net effect of anthropogenic aerosols is clearly negative (cooling), totalling about -1.2 W / m2 since the dawn of the industrial era in 1750 to 2005.

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.

«Residual analysis does not provide any evidence for a substantial cooling effect due to sulfate aerosols from 1940 to 1970... sulfate aerosols produced by volcanoes or industrial emissions no doubt have a cooling effect»

In contrast, increased industrial and volcanic aerosols restrict the penetration of solar radiation to the Earth's surface and lead to surface cooling.

On the other end of the spectrum, the industrial sector releases such a high proportion of sulfates and other cooling aerosols that it actually contributes a significant amount of cooling to the system.

If we account for the cooling effect of sulphur aerosols from industrial pollution, greenhouse gases have already contributed 2 ℃ of global warming.

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.

For example, if aerosols caused net cooling in the industrial Northern hemisphere, the positive feedback would magnify the cooling effect.)

If this were the case, we would see those colored global warming maps with cooling in industrial aerosol - rich areas and warming in the rest of the world, but we just don't see that.
