Not exact matches

Although the ions are not the most numerous constituents in the atmosphere the electro - magnetic interactions between ions and aerosols compensate for the scarcity and make fusion between ions and aerosols much more likely.

A few of the main points of the third assessment report issued in 2001 include: An increasing body of observations gives a collective picture of a warming world and other changes in the climate system; emissions of greenhouse gases and aerosols due to human activities continue to alter the atmosphere in ways that are expected to affect the climate; confidence in the ability of models to project future climate has increased; and there is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities.

The team conducted most of the study's experiments during the summer of 2012 in Karlsruhe, Germany, at the Aerosol Interaction and Dynamics in the Atmosphere (AIDA) facility — a former nuclear reactor that has since been converted into the world's largest cloud chamber.

Moreover, most aerosol emissions only stay in the atmosphere for a few days.

Now, scientists can add aerosols» fundamental properties into the models, opening the door to discover how the most abundant particulates in the atmosphere affect our climate and air quality.

Why it matters: Aerosol processes — how they behave and interact with clouds in the atmosphere — are among the most important — yet most difficult to simulate, aspects of climate modeling.

With a small amount of LW penetrating into the first three meters and a normal mid-ocean Wind and Wave complex most of the radiant energy is also returned to the atmosphere if not as direct heat then in the form of warm salt aerosols?

This is a peer reviewed paper by respected scientists who are saying that aerosol forcing means that the majority of the warming caused by existing co2 emission has effectively been masked thus far, and that as aerosols remain in the atmosphere for far shorter a duration of time than co2, we will have already most likely crossed the 2 degree threshold that the G8 politicians have been discussing this week once the cooling effect of aerosols dissipate.

It is likely that at least some of this change, particularly over Europe, is due to decreases in pollution; most governments have done more to reduce aerosols released into the atmosphere that help global dimming instead of reducing CO2 emissions.

In my mind, the most serious peril of sulfate geoengineering is one that stems from a problem that is not at all in dispute: the fact that the lifetime of CO2 in the atmosphere is centuries to millennia, whereas the lifetime of aerosols in the stratosphere is at best a few yearIn my mind, the most serious peril of sulfate geoengineering is one that stems from a problem that is not at all in dispute: the fact that the lifetime of CO2 in the atmosphere is centuries to millennia, whereas the lifetime of aerosols in the stratosphere is at best a few yearin dispute: the fact that the lifetime of CO2 in the atmosphere is centuries to millennia, whereas the lifetime of aerosols in the stratosphere is at best a few yearin the atmosphere is centuries to millennia, whereas the lifetime of aerosols in the stratosphere is at best a few yearin the stratosphere is at best a few years.

New evidence shows that the ocean also acts as a source of organic matter from biogenic origin -LSB-...] Surface - active organic matter of biogenic origin -LSB-...] enriched in the oceanic surface layer and transferred to the atmosphere by bubble - bursting processes, are the most likely candidates to contribute to the observed organic fraction in marine aerosol.

You claim chinas temperatures have continued to increase recently despite their coal burning and sulphate aerosols, with no basic knowledge that 1) they have filters on the power stations to remove most particulate matter like this since the 1980's, and 2) CO2 accumulates in the atmosphere overwhelming particulates, which are short lived in the atmosphere.

Upon chemical transformation in the atmosphere, most aerosols become more or less spherical.
