NCAR scientists and partners next week will launch a field project in the tropical Pacific, a remote region that holds a key to understanding worldwide climate. The warm waters fuel huge clusters of thunderstorms that act as a global chimney, lofting gases and particles into the stratosphere and affecting the planet. Boulder, CO (PRWEB) January 07, 2014 Even though few people live in the western tropical Pacific Ocean, these remote waters affect billions of people by shaping climate and...

Inside Ozone Hole NASA Data

Brett Smith for redOrbit.com - Your Universe Online A small hole in the Earth’s protective ozone layer appears annually over Antarctica and scientists have found that the 2012 ozone hole was the second-smallest hole since the mid 1980s. However, NASA scientists have also found that the hole in the ozone layer isn’t near to completely closing despite an international agreement to limit the emissions of ozone-depleting chlorofluorocarbons (CFC) more than 20 years ago –...

Ozone Tracking From The Space Station

Brett Smith for redOrbit.com - Your Universe Online Atmospheric researchers at the University of Utah have uncovered a Rube Goldberg-like mechanism that begins in the polar stratosphere and drives global weather patterns through a chain of interactions, according to a new report. "It is not new that the stratosphere impacts the troposphere," said University of Utah professor Thomas Reichler, senior author of the report published in the journal Nature Geoscience. "It also is not new...

Smaller Volcanoes Could Cool Climate According To Satellite Research
2012-07-05 16:33:57

A University of Saskatchewan-led international research team has discovered that aerosols from relatively small volcanic eruptions can be boosted into the high atmosphere by weather systems such as monsoons, where they can affect global temperatures. The research appears in the July 6 issue of the journal Science. Adam Bourassa, from the U of S Institute of Space and Atmospheric Studies, led the research. He explains that until now it was thought that a massively energetic eruption was...

Humans pump thousands of tons of vapor from the metallic element mercury into the atmosphere each year, and it can remain suspended for long periods before being changed into a form that is easily removed from the atmosphere. New research shows that the upper troposphere and lower stratosphere work to transform elemental mercury into oxidized mercury, which can easily be deposited into aquatic ecosystems and ultimately enter the food chain. "The upper atmosphere is acting as a chemical...
