The impact
of aerosols on climate is also discussed in this chapter, including interactions between aerosols and clouds.
Overall, improving our understanding of one of the largest natural aerosol sources is critical if we are to understand the effects of human -
made aerosols on climate,» says Matt Salter.
Collection of data regarding tropical forests was coordinated by Artaxo, as part of two Thematic Projects supported by the São Paulo Research Foundation — FAPESP: «GoAmazon: interactions of the urban plume of Manaus with biogenic forest emissions in Amazonia,» and «AEROCLIMA: direct and indirect effects of
aerosols on climate in Amazonia and Pantanal.»
Basic physical science considerations, exploratory climate modeling, and the impacts of
volcanic aerosols on climate all suggest that SWCE could partially compensate for some effects — particularly net global warming — of increased atmospheric CO2.
This section assesses (1) the impact of meteorological (climatic) factors like wind, temperature and precipitation on the natural aerosol burden and (2) possible effects of
aerosols on climate parameters and biogeochemistry.
While multiple studies have shown the Northern Hemisphere plays a stronger role than the Southern Hemisphere in transient climate change, this had not been included in calculations of the effect of
atmospheric aerosols on climate sensitivity.
However, given the sensitivity of the Arctic to external forcing and the intense interest in the effects of
aerosols on its climate, it is important to examine and quantify the effects of individual groups of anthropogenic forcing agents.
[~ 17 model years](Motivation: Variation in the climate response across models will be a function of (a) different climate sensitivity in the GCMs, (b) different impact of
aerosols on climate (due to location with respect to clouds, water uptake, natural aerosols, mixing, etc), and (c) different 3D constituent fields from the composition models.
The effects of
aerosols on the climate are a problem for the L&S model, as the authors almost admit in the paper:
The impacts of
aerosols on climate are significant, but also very uncertain.
