Why do atmospheric aerosols have a cooling effect? Explain why CFCs eventually make their way into the stratosphere even though most chemicals released into the atmosphere do not. Why is the ozone layer so important? What is the importance of the ozone layer to...
C.To help explain why it is unclear whether aerosols have the effect of counteracting warming D.To explain in part why scientists are uncertain how much incoming radiation is absorbed or reflected 阅读原文中文译文 To predict what the climate will be like in the future, scientists must rely on...
For minimizing the uncertainties in assessing this kind of cooling effect, all kinds of factors are analyzed which have been mixed in the assessment process and may lead to the different results of the radiative forcing of aerosols. It is noticed that one of the uncertainties to assess the ...
Aerosols act as cloud condensation nuclei, causing more clouds to form. Some aerosols can reflect sunlight in space, possibly cooling the climate by blocking the sun's energy. On the other hand, aerosols like black carbon can absorb heat, having the opposite effect. "We're looking at pr...
Major explosive volcanic eruptions eject water vapor and sulfur dioxide into the lower stratosphere where they form aerosols or mists that reflect and scatter sunlight. Each major eruption causes cooling of approximately one-half degree Celsius, 0.9 degrees Fahrenheit, for two to four years. This sho...
control their environment using these chemicals. The compounds react with air to produce aerosols that act as nucleation points or "seeds" for water, promoting cloud formation and conferring a cooling effect. The aerosols are visible. Have you ever wondered why the Smoky Mountains actually appear ...
Against the backdrop of global warming, El Niño conditions have an additive effect, pushing temperatures to record highs. This has combined with a reduction in aerosols, which are small particles that can deflect incoming solar radiation. So these two factors are most likely to blame for the...
However, the reaction products of VOCs cancontribute to aerosols, which reflect incoming solar radiation and help form clouds. Increases in these aerosols with rising VOC emissions from greater forest cover result in more radiation escaping to space. ...
4) The funny thing about that is the volcano produced tons of condensation nuclei in the form of sulfur compounds . There should be MORE contrails than ever before…. for a while anyway. Had the planes flown through the dust in the air, they would have created many more persistent contrai...
sunlight. Note that this doesnotnecessarily require an increase in the output of the sun. A change in any of the myriad processes that control the Earth’s average cloud cover can also do this. For instance, the IPCC talks about manmade particulate pollution (“aerosols”)...
