Kelly April Tyrrell, University of Wisconsin-Madison When the Intergovernmental Panel on Climate Change (IPCC) recently requested a figure for its annual report, to show global temperature trends over the last 10,000 years, the University of Wisconsin-Madison’s Zhengyu Liu knew that was going to be a problem. “We have been building models and there are now robust contradictions,” says Liu, a professor in the UW-Madison Department of Atmospheric and Oceanic Sciences and the Center...

Atlantic Ocean Dances With The Sun And Volcanoes
2014-04-01 09:06:11

By Christina Troelsen, Aarhus University Natural fluctuations in the ocean temperature in the North Atlantic have a significant impact on the climate in the northern hemisphere. These fluctuations are the result of a complex dance between the forces of nature, but researchers at Aarhus University can now show that solar activity and the impact of volcanic eruptions have led this dance during the last two centuries. Imagine a ballroom in which two dancers apparently keep in time to...

Peru Ice Cap Shrinking Due To Warming Temps, Not Less Snowfall
2014-02-26 12:56:35

Brett Smith for redOrbit.com - Your Universe Online When we think about how climate change is shrinking glaciers around the world – we are probably imagining the massive sheets of ice around the Earth’s polar regions. However, glaciers do exist in tropical latitudes, albeit at extremely high elevations, and a new study in the journal Geology has found that one of these tropical glaciers is shrinking as a result of warming temperatures – not lower snowfall levels as some scientists...

Solar Activity Little Effect On Climate
2013-12-23 10:45:26

Brett Smith for redOrbit.com - Your Universe Online From the Medieval Climate Anomaly to the Little Ice Age, average temperatures on Earth have varied significantly over the past thousand years. And according to a new study in Nature Geoscience that variation has little to do the amount of activity from the Sun. The Medieval Climate Anomaly, which lasted from approximately 950 to 1250, was a warming period in certain regions. The Little Ice Age, which lasted from about 1450 to 1850, is...

For the first time a long temperature reconstruction on the basis of stable carbon isotopes in tree rings has been achieved for the eastern Mediterranean. An exactly dated time series of almost 900 year length was established, exhibiting the medieval warm period, the little ice age between the 16th and 19th century as well as the transition into the modern warm phase. Moreover, Ingo Heinrich from the GFZ German Research Centre for Geosciences and colleagues revealed that the modern warming...

Global Warming To Shift Rain And Wind Belts: Experts
2013-09-24 04:32:23

April Flowers for redOrbit.com - Your Universe Online A new study from Columbia University's Lamont-Doherty Earth Observatory reveals that a northward shift of Earth's wind and rain belts could make a broad swath of regions drier. The findings, published in Proceedings of the National Academy of Sciences, show that these drier regions include the Middle East, American West and Amazonia, while Monsoon Asia and equatorial Africa will become wetter as humans continue to heat the planet....

Rainfall In South Pacific Varied Much More Dramatically Before 20th Century
2013-09-10 09:16:25

The University of Texas at Austin A new reconstruction of climate in the South Pacific during the past 446 years shows rainfall varied much more dramatically before the start of the 20th century than after. The finding, based on an analysis of a cave formation called a stalagmite from the island nation of Vanuatu, could force climate modelers to adjust their models. The models are adjusted to match the current levels of climate variability that are smaller now than they were in the recent...

Black Carbon Suspect In Mid-1800s Alps Glacier Retreat
2013-09-03 08:17:32

University of Colorado at Boulder Scientists have uncovered strong evidence that soot, or black carbon, sent into the air by a rapidly industrializing Europe, likely caused the abrupt retreat of mountain glaciers in the European Alps. The research, published Sept. 2 in the Proceedings of the National Academy of Sciences, may help resolve a longstanding scientific debate about why the Alps glaciers retreated beginning in the 1860s, decades before global temperatures started rising again....

Clam Shells Record Climate Events Over Past Thousand Years
2012-10-02 15:05:18

Brett Smith for redOrbit.com - Your Universe Online Modern climatologists have access to a wide array of technological tools, but an international team looking to study climate events from the past thousand years has decided to utilize something a little more old school. Researchers led by Alan Wanamaker from Iowa State University have been collecting clam shells from the waters of the North Atlantic because the mollusks act as tiny recorders, storing information about their environment...


Word of the Day
out-herod
  • In the phrase to out-herod Herod, to be more violent than Herod (as represented in the old mystery plays); hence, to exceed in any excess of evil.
Herod refers to 'Herod the Great,' a Roman client king and 'a madman who murdered his own family and a great many rabbis.' According to the OED, the term is 'chiefly with allusion to Shakespeare's use' in Hamlet.
