Direct evidence for a positive feedback in climate change
A new study has confirmed the existence of a positive feedback operating in climate change whereby warming itself may amplify a rise in greenhouse gases resulting in additional warming.
Speed with which temperatures change will continue to increase over next several decades, study shows
An analysis of changes to the climate that occur over several decades suggests that these changes are happening faster than historical levels and are starting to speed up. The Earth is now entering a period ...
New ozone-destroying gases on the rise
Scientists report that chemicals that are not controlled by a United Nations treaty designed to protect the Ozone Layer are contributing to ozone depletion.
New solar power material converts 90 percent of captured light into heat
A multidisciplinary engineering team at the University of California, San Diego developed a new nanoparticle-based material for concentrating solar power plants designed to absorb and convert to heat more ...
Study shows increase of CO2 in the atmosphere is lower than predicted because of plants
Hot tropical oceans during Pliocene greenhouse warming
The impact of the greenhouse gas CO2 on the Earth's temperature is well established by climate models and temperature records over the past 100 years, as well as coupled records of carbon dioxide concentration ...
New material coating technology mimics nature's lotus effect (w/ video)
Ever stop to consider why lotus plant leaves always look clean? The hydrophobic – water repelling – characteristic of the leaf, termed the "Lotus effect," helps the plant survive in muddy swamps, repelling ...
Shiny quantum dots brighten future of solar cells
(Phys.org) —A house window that doubles as a solar panel could be on the horizon, thanks to recent quantum-dot work by Los Alamos National Laboratory researchers in collaboration with scientists from University ...
Researchers estimate amount of CO2 released into atmosphere by rivers and streams
Fossil shells and new geochemical technique provide clues to ancient climate cooling
Using a new laboratory technique to analyze fossil snail shells, scientists have gained insights into an abrupt climate shift that transformed the planet nearly 34 million years ago.
Global carbon dioxide levels reach new monthly record (Update)
In another ominous sign of human-caused climate change, US government scientists said Wednesday that global carbon dioxide concentrations have reached a new monthly record of 400 parts per million.
Heat still on despite warming slowdown
The recent slowdown in the rise of global average air temperatures will make no difference to how much the planet will warm by 2100, a new study has found.
Global warming progressing at moderate rate, empirical data suggest
A new study based on 1,000 years of temperature records suggests global warming is not progressing as fast as it would under the most severe emissions scenarios outlined by the Intergovernmental Panel on ...
New method to engineer surfaces along multiple directions in a nanowire
Nanoscale one-dimensional nanostructures (i.e. nanowires) offer vast opportunities in photovoltaics and photonics due to their exceptional optical and electrical properties, which are entirely tunable by ...
