New aerosol observing technique turns gray skies to blue (w/Video)
(PhysOrg.com) -- Tiny, ubiquitous particles in the atmosphere may play a profound role in regulating global climate. But the scientists who study these particles -- called aerosols -- have long...
View ArticleClimate balancing: Sea-level rise vs. surface temperature change rates
Engineering our way out of global climate warming may not be as easy as simply reducing the incoming solar energy, according to a team of University of Bristol and Penn State climate scientists....
View ArticleEffects of sea spray geoengineering on global climate
Anthropogenic climate warming is leading to consideration of options for geoengineering to offset rising carbon dioxide levels. One potential technique involves injecting artificial sea spray into the...
View ArticleClimate expert: Record loss of arctic ice could impact Wisconsin
Ice covering the Arctic Ocean melted to the smallest areal extent ever recorded this year, falling to 1.3 million square miles at its lowest point on Sept. 16, according to the National Snow and Ice...
View ArticleCirrus clouds form around mineral dust and metallic particles, study finds
At any given time, cirrus clouds—the thin wisps of vapor that trail across the sky—cover nearly one-third of the globe. These clouds coalesce in the upper layers of the troposphere, often more than 10...
View ArticleNCAR joins massive field campaign to examine summertime air in Southeast
Taking part in the largest U.S. air quality field project in decades, the National Center for Atmospheric Research (NCAR) is working with partners to study pollution in the Southeast. The study looks...
View ArticleNew solar cell technology captures high-energy photons more efficiently
(Phys.org) —Getting the blues is rarely a desirable experience—unless you're a solar cell, that is.
View ArticleResearchers study water cycle and cloud formation and design computer...
In the past, many atmospheric scientists believed that pollen particles probably had a negligible effect on climate because they were so big. In recent years, however, as they began to realize that...
View ArticleClimate change generates more Arctic tundra vegetation
Researchers in Finland have discovered that climate change has impacted various regions of the Arctic tundra by helping increase the levels of vegetation. Their data suggest that this rise could...
View ArticleArctic ice melt sets stage for cold weather
(Phys.org) -- The dramatic melt-off of Arctic sea ice due to climate change is hitting closer to home than millions of Americans might think. That's because melting Arctic sea ice can trigger a domino...
View ArticleVolcanic eruptions slow down climate change - temporarily
Although global concentration of greenhouse gases in the atmosphere has continuously increased over the past decade, the mean global surface temperature has not followed the same path. A team of...
View ArticlePlant gases can counteract Arctic climate change
Plant gasses possibly dampen the temperature rise in Greenland. Plants emit compounds to deter pests or attract pollinators, and as a side effect particles are formed when the compounds interact in the...
