Sentences with phrase «effects of aerosols generated»

The leveling off between the 1940s and 1970s may be explained by natural variability and possibly by cooling effects of aerosols generated by the rapid economic growth after World War II.

Not exact matches

The net effect of human - generated aerosols is more complicated and regionally variable — for example, in contrast to the local warming effect of the Asian Brown Cloud, global shipping produces large amounts of cooling reflective sulphate aerosols: http://www.sciencedaily.com/releases/1999/08/990820022710.htm

If industry - generated aerosols have a more limited cooling effect than originally thought, we can clean up and scale down dirty coal plants without worrying too much about consequent sudden jumps in global temperatures of up to 2 degrees C (if I remember the upper limits of earlier studies correctly).

The problem arises, I believe, when strong feedbacks, «masking» effects of aerosols and volcanoes and other uncertain assumptions are fed into computer models to generate catastrophic scenarios for the near - medium future.

Given our very short and spotty data on the relative abundance (or importance) of the majority of these aerosols, and given our very poor understanding of the direct, indirect, and side effects of the majority of these aerosols, any numbers that anyone generates about their abundance, importance, or total radiative forcing are going to be a SWAG.

But including aerosol indirect effects on radiative forcing has made it easier to generate a greater variety of 20th century simulations without affecting other aspects of the climate simulation as strongly.

Though natural variability (external and internally generated — including the cooling effect of naturally produced aerosols) would affect the final temperature achieved, this would not affect the calculation of TCR as long as natural variability is accounted for.

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.

For the «Aerosol - Cloud Interaction» (ACI): There is a recent paper http://onlinelibrary.wiley.com/doi/10.1002/2017GL075280/full which shows that this effect is very small in the real world but models use it «excessive» to generate a big negative aerosol forcing (see fig. 2 of the main arAerosol - Cloud Interaction» (ACI): There is a recent paper http://onlinelibrary.wiley.com/doi/10.1002/2017GL075280/full which shows that this effect is very small in the real world but models use it «excessive» to generate a big negative aerosol forcing (see fig. 2 of the main araerosol forcing (see fig. 2 of the main articel).

As aerosol pollution is predicted to decrease over the next few decades, unmasking of the greenhouse effect may lead to accelerated global warming.storms and ocean plankton The human - generated aerosols are derived from industry, motor vehicles and vegetation burning.

Global Climate Change Another Dire Global Warming Effect: 10 Times as Many Ocean Dead Zones Global Warming to Blame for 37 % of Droughts Human - Generated Aerosols May be Masking the Warming Effects of Climate Change

Whilst apparently long known to exert a cooling effect on climate, human - generated aerosols have partly masked the warming effect of increasing greenhouse gases.

The direct and indirect effects of human - related aerosols on radiation, cloud, precipitation, and so on, might play an important role in generating the opposite signal in the weekend effect for different seasons.
