An international team of scientists has detected that some of the glow of Earth’s aurora is polarized, an unexpected state for such emissions. Measurements of this newfound polarization in the…

Monitoring Earth's rising greenhouse gas levels will require a global data collection network 10 times larger than the one currently in place in order to quantify regional progress in emission…

In 1600 eruption of Huaynaputina in Peru put a large amount of sulfur into the atmosphere. Sulfur reacts with water in the air to form droplets of sulfuric acid, which cool the planet by reducing…

The biggest blow-up in the science community about Al Gore's "An Inconvenient Truth" was not over the 20 foot ocean rises but the images of Hurricane Katrina and the implication that global warming…

A new study shows that wetland regions emitted significantly less methane during glacial times while methane emissions by forest fire activity remained surprisingly constant from glacial to…

A team of European scientists has triggered electrical activity in thunderclouds for the first time - deliberately. They did it by aiming high-power pulses of laser light into a thunderstorm. Next,…

A new technique that helps forecasters continuously monitor landfalling hurricanes, giving them frequent and detailed images of a storm's location, will be implemented this summer. The new system,…

Research published in the Institute of Physics' Environmental Research Letters shows how a team from Lancaster and Durham Universities sought a means to prove the correlation between the ionizing…

Nitrous oxide, laughing gas, can't get any respect. Unlike carbon dioxide and methane, laughing gas has been largely ignored by world leaders as a worrying greenhouse gas but nitrous oxide must be…

Chemists at the University of California, San Diego have discovered that a chemical reaction in the atmosphere above major cities long assumed to be unimportant in urban air pollution is in fact a…
