Depletion of Antarctic ozone is a more important factor than increasing greenhouse gases in shifting the Southern Hemisphere jet stream in a southward direction, according to researchers at Penn State.
The heat generated by everyday activities in metropolitan areas has a significant enough warming effect to influence the character of the jet stream and other major atmospheric systems during winter months, according to a trio of climate researchers.
A new supercomputer expected to rank among the world’s fastest machines will be ready to run computationally intense climate and biological simulations along with other scientific programs this summer. This computational work will aid research in climate and environmental science, chemical processes, biology-based fuels that can replace fossil fuels, new materials for energy applications and more.
Glaciers in the tropical Andes have been retreating at increasing rate since the 1970s, scientists write in the most comprehensive review to date of Andean glacier observations.
Warmer temperatures due to climate change could cause soils to release additional carbon into the atmosphere, thereby enhancing climate change – but that effect diminishes over the long term, finds a new study in the journal Nature Climate Change. The study, from University of New Hampshire professor Serita Frey and co-authors from the University of California-Davis and the Marine Biological Laboratory, sheds new light on how soil microorganisms respond to temperature and could improve predictions of how climate warming will affect the carbon dioxide flux from soils.
Longer, warmer growing seasons associated with a changing climate are altering growing conditions in temperate rain forests, but not all plant species will be negatively affected, according to research conducted by the U.S. Forest Service's Pacific Northwest Research Station.
UCLA professor Thomas B. Smith will head an international research project investigating the effects of climate change on biodiversity in Central Africa's rainforests, under a $4.95 million grant from the National Science Foundation.
The National Science Foundation (NSF) today announced the 12 projects funded in a fourth round of Partnerships for International Research and Education (PIRE) awards. Many of these projects engage scientists in research to develop clean, safe, reliable, affordable energy alternatives, as the need for solutions challenges societies across the globe.
Today, over 20 Latino leaders and organizations submitted a letter to the White House today asking President Obama and the Environmental Protection Agency for strong standards to limit carbon pollution from existing power plants. The Latino population in the United States is particularly vulnerable to the effects of carbon pollution since fully one-half live in counties currently in violation of clean air standards.
In addition to causing smoggy skies and chronic coughs, soot – or black carbon – turns out to be the number two contributor to global warming. It's second only to carbon dioxide, according to a four-year assessment by an international panel.
