Sentences with phrase «aerosol levels»

Would you care to explain to me why you are confident about the estimates of atmospheric aerosol levels that are available for that period?

But if aerosol cooling is larger than generally assumed, the planet will warm more rapidly than predicted as soon as aerosol levels fall.

For good reasons, aerosol levels look set to fall.

Natural Variability Doesn't Account for Observed Temperature Increase In it's press release announcement, NASA points out that while there are other factors than greenhouse gases contributing to the amount of warming observed — changes in the sun's irradiance, oscillations of sea surface temperatures in the tropics, changes in aerosol levels in the atmosphere — these factors are not sufficient to account for the temperature increases observed since 1880.

What a convenient way to avoid admitting that despite the 2006 - 7 Atlantic hurricane seasons being less active than 2005, there is nonetheless a strong upward trend in Atlantic hurricane activity — which, while perhaps not caused by global warming, shows a correlation with rising sea surface temperatures in the Atlantic, and with changing aerosol levels over the Atlantic (See Mann and Emanuel, 2006)

So while GHG levels have been greater than aerosol levels for many decades in terms of absolute magnitude, they have only recently overtaken the cooling effect of aerosols in terms of their influence on storm intensity.

These clouds then glaciate in higher levels, which could result in either more or less vigorous precipitation formation depending on the background aerosol levels and atmospheric stability (Khain et al., 2004).

Combinations of satellite and surface - based observations allow us to determine trends in aerosol levels as well as cloud albedo effect.

Using different instruments, satellites can measure atmospheric aerosol levels, ground elevations, and more.

But that points up another potential problem: if aerosol levels, whether natural or human - made, decline in the future, climate change could accelerate — and China is adding scrubbing technology to its coal - fired power plants to reduce SO2 emissions and thereby minimize acid rain.

Besides showing pretty views, EPIC provides scientists with metrics on climate such as cloud height, ultraviolet reflectivity, or ozone and aerosol levels.

Three others key factors — including changes in the Sun's irradiance, oscillations of sea surface temperature in the tropics, and changes in aerosol levels — can also cause slight increases or decreases in the planet's temperature.

As the CO2 sensitivity is adjusted down, the aerosol level sensitivity may be as well.

You can measure (theoretically) aerosol levels and ozone.

The information gathered by EPIC will help us examine a range of Earth properties, such as ozone and aerosol levels, cloud coverage, and vegetation density, supporting a number of climate science applications.
