To determine whether declining pollutants deserve credit for the recovery, the researchers used a 3D atmospheric model to separate the effects of the chemicals from those of weather, which can affect ozone loss through winds and temperature, and volcanic eruptions, which deplete ozone by pumping sulfate particles into the upper atmosphere.
Black carbon aerosols — particles of carbon that rise into the atmosphere when biomass, agricultural waste, and fossil fuels are burned in an incomplete way — are important for understanding climate change, as they absorb sunlight, leading to higher atmospheric temperatures, and can also coat Arctic snow with a darker layer, reducing its reflectivity and leading to increased melting.

The resulting lower atmospheric CO2, the argument goes, would mean lower temperatures, suggesting that the mechanism was at least partially responsible for triggering past ice ages.

Another principal investigator for the project, Laura Pan, senior scientist at the National Center for Atmospheric Research in Boulder, Colo., believes storm clusters over this area of the Pacific are likely to influence climate in new ways, especially as the warm ocean temperatures (which feed the storms and chimney) continue to heat up and atmospheric patterns continue to evolve.
Yet there is no doubt that research into atmospheric aerosols is becoming increasingly important due to the effects that they can have on the global temperature of Earth, given that solar radiation is the main source of energy for Earth - Atmosphere system.
New measurements by NASA's Goddard Institute for Space Studies indicate that 2012 was the ninth warmest year since 1880, and that the past decade or so has seen some of the warmest years in the last 132 years.One way to illustrate changes in global atmospheric temperatures is by looking at how far temperatures stray from «normal», or a baseline.
The results suggest that the impact of sea ice seems critical for the Arctic surface temperature changes, but the temperature trend elsewhere seems rather due mainly to changes in ocean surface temperatures and atmospheric variability.

But ocean temperatures alone don't define an El Niño; CPC forecasters also look for the corresponding shifts in atmospheric patterns, namely a weakening of the typical east - to - west trade winds over the region.

By analyzing global water vapor and temperature satellite data for the lower atmosphere, Texas A&M University atmospheric scientist Andrew Dessler and his colleagues found that warming driven by carbon dioxide and other gases allowed the air to hold more moisture, increasing the amount of water vapor in the atmosphere.
