Seasonal carbon dioxide range expanding as more is added to Earth's atmosphere
Levels of carbon dioxide in the atmosphere rise and fall each year as plants, through photosynthesis and respiration, take up the gas in spring and summer, and release it in fall and winter.
New and remarkable details of the Sun now available from Big Bear Observatory
Researchers at NJIT's Big Bear Solar Observatory (BBSO) in Big Bear, CA have obtained new and remarkably detailed photos of the Sun with the New Solar Telescope (NST). The photographs reveal never-before-seen ...
Next generation of unmanned aircraft to boost geoscientific research
The University of Southampton is developing new unmanned aircraft for science applications and geoscientific research.
Radio waves carry news of climate change
The ionosphere, one of the regions of the upper atmosphere, plays an important role in global communications. Ionized by solar radiation, this electricity-rich region is used for the transmission of long ...
Dual radar storm analysis technique works even with one, research says
(Phys.org) —Scientists may be able to better study how supercell thunderstorms work by using the data from just one Doppler radar unit and an analysis technique called synthetic dual-Doppler (SDD) that ...
World changing technology enables crops to take nitrogen from the air
A major new technology has been developed by The University of Nottingham, which enables all of the world's crops to take nitrogen from the air rather than expensive and environmentally damaging fertilisers.
Tropical ecosystems regulate variations in Earth's carbon dioxide levels
The study, published in the journal Proceedings of the National Academy of Sciences, found that a temperature anomaly of just 1ºC (in near surface air temperatures in the tropics) leads to a 3.5-Petagram (billi ...
Ancient ice melt unearthed in Antarctic mud
Global warming five million years ago may have caused parts of Antarctica's large ice sheets to melt and sea levels to rise by approximately 20 metres, scientists report today in the journal Nature Geoscience.
LADEE lunar probe unveiled at NASA's wallops launch site in Virginia
NASA's Lunar Atmosphere and Dust Environment Explorer (LADEE) Observatory has arrived at the launch site on the Eastern Shore of Virginia at NASA's Wallops Flight Facility on Wallops Island and is now in ...
Trees using water more efficiently as atmospheric carbon dioxide rises
A study by scientists with the U.S. Forest Service, Harvard University and partners suggests that trees are responding to higher atmospheric carbon dioxide levels by becoming more efficient at using water.
Cloud brightening to cool seas can protect coral reefs
The seeding of marine clouds to cool sea surface temperatures could protect threatened coral reefs from being bleached by warming oceans. Research, published in Atmospheric Science Letters, proposes that a targeted versio ...
Rocks can restore our climate... after 300,000 years
(Phys.org) —A study of a global warming event that happened 93 million years ago suggests that the Earth can recover from high carbon dioxide emissions faster than previously thought, but that this process ...
Researchers warn of legacy mercury in the environment
Environmental researchers at Harvard University have published evidence that significant reductions in mercury emissions will be necessary just to stabilize current levels of the toxic element in the environment. ...
Chemistry researchers closing in on new atomic force microscope
(Phys.org) —A high-power atomic force microscope that could revolutionize the study of materials at high temperatures and pressures is coming into focus in a Wright State University lab.
