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
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.
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.
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.
Materials scientists make solar energy chip 100 times more efficient
(Phys.org) —Scientists working at the Stanford Institute for Materials and Energy Sciences (SIMES) have improved an innovative solar-energy device to be about 100 times more efficient than its previous ...
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 ...
The Curiosity robot confirms methane in Mars' atmosphere which may hint that existed life
The tunable laser spectrometer in the SAM (Sample Analysis at Mars) instrument of the Curiosity robot has unequivocally detected an episodic increase in the concentration of methane in Mars' atmosphere after ...
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 ...
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.
New type of solar concentrator doesn't block the view
(Phys.org) —A team of researchers at Michigan State University has developed a new type of solar concentrator that when placed over a window creates solar energy while allowing people to actually see through ...
Climate change caused by ocean, not just atmosphere, study finds
Most of the concerns about climate change have focused on the amount of greenhouse gases that have been released into the atmosphere.
