The percentage of Earth’s land area stricken by serious drought more than doubled from the 1970s to the early 2000s, according to a new analysis by scientists at the National Center for Atmospheric Research (NCAR) in Boulder, Colo. Widespread drying occurred over much of Europe and Asia, Canada, western and southern Africa, and eastern Australia. Rising global temperatures appear to be a major factor, says NCAR scientist Aiguo Dai.

Dai will present the new findings on Weds.

Two 19th century scientists, each involved with a mountain top observatory, and who each in their own way contributed to the development of ‘big science’ research in the 20th-21st centuries, are to be celebrated by an arts initiative to which University of Leicester space scientists have made an important contribution.

A new discovery by a team of Queen’s University scientists suggests that ancient earth was much colder than previously thought – a discovery that has broad implications for those studying the earth’s climate.

Queen’s researchers have discovered the mineral ikaite in 700-million-year-old marine sedimentary rocks in the Mackenzie Mountains of the Northwest Territories and eastern Yukon. This discovery proves that the ancient ocean was much colder than previously believed, says Noel Ja

Scientists using NASA satellite data found the shape of the Earth appears to be influenced by big climate events that cause changes in the mass of water stored in oceans, continents and atmosphere.

The study’s principal researchers are Minkang Cheng and Byron D. Tapley, of the Center for Space Research, University of Texas at Austin. They reviewed climate events like El Niño Southern Oscillation (ENSO) and Pacific Decadal Oscillation (PDO) that affect the amount of water moving in
