The question seems simple enough: What happens to the Earth's temperature when atmospheric carbon dioxide levels increase? The answer is elusive. However, clues are hidden in the fossil record. A new study by researchers from Syracuse and Yale universities provides a much clearer picture of the Earth's temperature approximately 50 million years ago when CO2 concentrations were higher than today. The results may shed light on what to expect in the future if CO2 levels keep rising.
Australia will unveil the full details of its contentious pollution tax within days, Treasurer Wayne Swan said Tuesday, promising help for households facing higher energy bills.
As the Sun enters a period of low solar activity over the next 50 years, new research has calculated the probability of unusually cold winter temperatures occurring in the UK.
(PhysOrg.com) -- Latest research into the age of volcanos in Western Victoria and South Australia has confirmed that the regions are overdue for an eruption, potentially affecting thousands of local residents.
(AP) -- The space shuttle was sold to America as cheap, safe and reliable. It was none of those.
Showers and thunderstorms are likely to force a delay to this week's planned final launch of the space shuttle, NASA's weather officer said on Tuesday.
When NASA's 30-year-old space shuttle program is shuttered following the Atlantis mission in July, the University of Colorado Boulder will look back at a rich relationship filled with triumph and tragedy and look ahead to an evolving international program of government and private efforts that will send humans and cargo into orbit.
The University of Colorado Boulder is involved with five different space science payloads ranging from antibody tests that may lead to new bone-loss treatments to an experiment to improve vaccine effectiveness for combating salmonella when Atlantis thunders skyward July 8 on the last of NASA's 135 space shuttle missions.
(PhysOrg.com) -- US and Swiss researchers have, for the first time, modelled a climate system with extremely high carbon emissions in an attempt to test the boundaries of the current computer simulation programs that inform us.
An oil spill off China's eastern coast kept hidden from the public for weeks has caused long-term environmental damage that will hurt the area's fishing industry, state media reported Tuesday.
(PhysOrg.com) -- The world's first high definition streaming video camera to be installed on the International Space Station (ISS) has been announced by David Willetts, Minister for Universities and Science at the UK Space Conference on 4 July. The project is a joint venture between Canada, Russia and the UK.
NASA's Hubble Space Telescope crossed another milestone in its space odyssey of exploration and discovery. On Monday, July 4, the Earth-orbiting observatory logged its one millionth science observation during a search for water in an exoplanet's atmosphere 1,000 light-years away.

Some 50 miles up in the sky begins a dynamic region of the atmosphere known as the ionosphere. The region is filled with charged particles created by extreme ultraviolet radiation from the sun. At the base of the ionosphere, charged particle motions create a global current called the "atmospheric dynamo." Generally moving in loops from the equator to the poles, the dynamo changes daily based on solar heating and magnetic activity – but what keeps it moving isn't well understood.
