Statistical analysis rules out natural-warming hypothesis with more than 99 percent certainty An analysis of temperature data since 1500 all but rules out the possibility that global warming in the industrial era is just a natural fluctuation in the earth's climate, according to a new study by McGill University physics professor Shaun Lovejoy. The study, published online April 6 in the journal Climate Dynamics, represents a new approach to the question of whether global warming in the...

Scientists have known for decades that black carbon aerosols add to global warming. These airborne particles made of sooty carbon are believed to be among the largest man-made contributors to global warming because they absorb solar radiation and heat the atmosphere. New research from Carnegie's Long Cao and Ken Caldeira, along with colleagues George Ban-Weiss and Govindasamy Bala, quantifies how black carbon's impact on climate depends on its altitude in the atmosphere. Their work, published...

Imagine the vast, empty tundra in Alaska and Canada giving way to trees, shrubs and plants typical of more southerly climates. Imagine similar changes in large parts of Eastern Europe, northern Asia and Scandinavia, as needle-leaf and broadleaf forests push northward into areas once unable to support them. Imagine part of Greenland's ice cover, once thought permanent, receding and leaving new tundra in its wake. Those changes are part of a reorganization of Arctic climates anticipated to...

The increased frequency of drought observed in eastern Africa over the last 20 years is likely to continue as long as global temperatures continue to rise, according to new research published in Climate Dynamics. This poses increased risk to the estimated 17.5 million people in the Greater Horn of Africa who currently face potential food shortages. Scientists from the U.S. Geological Survey and the University of California, Santa Barbara, determined that warming of the Indian Ocean, which...

Chronology of growth rings from tropical Australia compiled for the first time Annual rings are acclaimed in representing natural climate archives. For the temperate latitudes it is known that the growth of these annual rings depend mainly on temperature and precipitation. In the tropics, however, with only slight seasonal variations, the correlation is not so evident. Now scientists of the GFZ German Research Center for Geosciences and their colleagues of the Australian National University...

baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
