Despite its smaller ash cloud, El Chichn emitted more than 40 times the volume of sulfur - rich gases produced by Mt. St. Helens, which revealed that the formation of atmospheric sulfur aerosols has a more substantial effect on global temperatures than simply the volume of ash produced during an eruption.

Much of the uncertainty surrounding clouds» effect on climate stems from the complexity of cloud formation.

At least over the oceans, the pre-industrial cloud conditions would have been considerably different from those of today; this implies that the aerosols we have been adding to the atmosphere may have had a significant effect on global patterns of cloud formation and rain.

The research also appears to solve one of the great unknowns of climate sensitivity, the role of cloud formation and whether this will have a positive or negative effect on global warming.

New modelling methods provide more precise information than ever on the effect of landforms on cloud formation

However, I am not optimistic — the specifics of the small scale physics (aerosol indirect effects on clouds, sea ice formation, soil hydrology etc.) are so heterogeneous that I don't see how you can do without calculating the details.

Microclimate really DO measure the turbulence around a scotts pine on its own and in a forest, checking what effect that has on cloud formation, convective lift and lots of other things.

wilt, the paper you cite describes what in their view is a «small but statistically significant effect of cosmic rays on cloud formation, which in no way invalidates the large and significant effects of human emissions on the current anthropogenic radiative forcing budget of the atmosphere.

Science marches on and each year will bring greater understanding of the roles that the ocean cycles, precipitation systems, cloud formation, and solar effects play in this gigantic system.

I agree about the albedo effect of snow, but the way albedo is formed has been given some insights with the new Svensmark paper on cloud formations.

In summary the findings to date indicate that the effect of cosmic rays on cloud formation is small compared to the large variations in natural biogenic aerosol emissions.

First, this effect (influence on cloud formation by solar cycle modulation of cosmic rays) has been known for half a century.

For some unexplained reason there have been a large number of coronal holes on the surface of the sun, in low latitude positions during solar magnetic cycle 24, however due to the reduction in the solar wind density the solar wind bursts have less effect on cloud modulation which explains why there has suddenly be an increase sea ice in the Antarctic, a recovery of sea ice in the Arctic, and an inhibiting of the formation of El Niño events.

In addition, the larger amount of open water leads to more moisture in the air, which affects the formation of clouds that have their own effect on warming, either enhancing or reducing it.

I was impressed that Singer highlighted the correlation between temperature and solar activity (and its corresponding effect on cosmic rays and low - cloud formation) that seems to have been dismissed by the IPCC.

On the other hand, if some of the anthropogenic aerosols act as ice nuclei, supercooled clouds could be converted into ice clouds by the glaciation indirect effect (Lohmann, 2002), resulting in more efficient precipitation formation.

It indicated that contrails — white lines of Vapor left by jet engines — also have big knock - on effects by adding to the formation of high - altitude, heat - trapping cirrus clouds as the lines break up.

IF this is the case, then varying cloud lifetimes (NOT cloud formation rates) would significantly affect average cloud fraction and thus have a significant effect on climate.

Topics that I work on or plan to work in the future include studies of: + missing aerosol species and sources, such as the primary oceanic aerosols and their importance on the remote marine atmosphere, the in - cloud and aerosol water aqueous formation of organic aerosols that can lead to brown carbon formation, the primary terrestrial biological particles, and the organic nitrogen + missing aerosol parameterizations, such as the effect of aerosol mixing on cloud condensation nuclei and aerosol absorption, the semi-volatility of primary organic aerosols, the importance of in - canopy processes on natural terrestrial aerosol and aerosol precursor sources, and the mineral dust iron solubility and bioavailability + the change of aerosol burden and its spatiotemporal distribution, especially with regard to its role and importance on gas - phase chemistry via photolysis rates changes and heterogeneous reactions in the atmosphere, as well as their effect on key gas - phase species like ozone + the physical and optical properties of aerosols, which affect aerosol transport, lifetime, and light scattering and absorption, with the latter being very sensitive to the vertical distribution of absorbing aerosols + aerosol - cloud interactions, which include cloud activation, the aerosol indirect effect and the impact of clouds on aerosol removal + changes on climate and feedbacks related with all these topics In order to understand the climate system as a whole, improve the aerosol representation in the GISS ModelE2 and contribute to future IPCC climate change assessments and CMIP activities, I am also interested in understanding the importance of natural and anthropogenic aerosol changes in the atmosphere on the terrestrial biosphere, the ocean and climate.

thanks, not a chemical effect on snow crystal formation in the clouds then since it's «only» a seasonal effect...
