Urine Of The Rock Hyrax Can Give Past Climate Clues
2013-02-18 08:40:23

Brett Smith for redOrbit.com - Your Universe Online Not cleaning a kitty´s litter box could be a disgusting thought for cat owners, but for Brian Chase of Montpellier University in France – layers of dried urine can reveal exciting new details about an environment as they stack up year after year and generation after generation. Instead of learning about the historical habitat of the common housecat, Chase and his colleagues from the European Research Council analyzed layers...

Snow Cover Worldwide Is At Record Lows
2012-12-04 07:25:37

April Flowers for redOrbit.com - Your Universe Online A new European Space Agency (ESA) study of snow cover observed by satellites reveals record lows in Eurasia for June each year since 2008. Three of the past five years have seen record low cover in North America, as well. Since satellite observations began some 45 years ago, this is the lowest June snow extent on record. Snow cover in June is falling faster than climate models have predicted. It is even disappearing faster than...

Arctic Climate Project Looking For Citizen Scientists
2012-10-25 04:06:11

Lee Rannals for redOrbit.com - Your Universe Online The National Oceanic and Atmospheric Administration (NOAA) is asking citizen scientists to come together to help reconstruct the historical climate of the Arctic. NOAA is teaming up with National Archives and Records Administration and Zooniverse, a citizen science web portal, to find volunteers to transcribe a newly digitized set of ship logs dating back to 1850. The ship logs are from the U.S. Navy, Coast Guard and Revenue Cutter...

The extent of the sea ice covering the Arctic Ocean has shrunk. According to scientists from NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) in Boulder, Colo., the amount is the smallest size ever observed in the three decades since consistent satellite observations of the polar cap began. NASA and NSIDC scientists will host a media teleconference at 3 p.m. EDT, today, to discuss this new record low for summertime Arctic sea ice cover. The extent of Arctic sea ice...

Climate In Arctic More Vulnerable Than Thought

First analyses of the longest sediment core ever collected on land in the terrestrial Arctic provide documentation that intense warm intervals, warmer than scientists thought possible, occurred there over the past 2.8 million years First analyses of the longest sediment core ever collected on land in the terrestrial Arctic, published this week in Science, provide documentation that intense warm intervals, warmer than scientists thought possible, occurred there over the past 2.8 million...

Arctic Ice Melt Setting The Stage For Severe Winters
2012-06-07 04:09:38

The dramatic melt-off of Arctic sea ice due to climate change is hitting closer to home than millions of Americans might think. That's because melting Arctic sea ice can trigger a domino effect leading to increased odds of severe winter weather outbreaks in the Northern Hemisphere's middle latitudes — think the "Snowmageddon" storm that hamstrung Washington, D.C., during February 2010. Cornell's Charles H. Greene, professor of earth and atmospheric sciences, and Bruce C. Monger,...

Continuing Deep Ocean Change In The Southern Ocean
2012-05-22 03:53:13

New research by teams of Australian and US scientists has found there has been a massive reduction in the amount of Antarctic Bottom Water found off the coast of Antarctica. Comparing detailed measurements taken during the Australian Antarctic program's 2012 Southern Ocean marine science voyage to historical data dating back to 1970, scientists estimate there has been as much as a 60 per cent reduction in the volume of Antarctic Bottom Water, the cold dense water that drives global ocean...

Pitt study one of many across the nation focused on understanding Arctic region´s climate changes Researchers at the University of Pittsburgh have joined an international group of scientists to study past climate changes in the Arctic. Comprising geologists from Pitt´s Department of Geology and Planetary Science, the team has analyzed sedimentary and geochemical records of water-level changes in Rantin Lake, located in the boreal forest of Canada´s southeastern Yukon...

Climatic Effects Of A Solar Minimum On Planet Earth
2012-05-07 05:00:52

Joshua Kelly for RedOrbit.com Researchers with the Helmholtz Association of German Research Centers are investigating a link between the massive solar minimum that occurred around 2800 years ago and the effects that it had on the climate of Europe.  They are still researching how the solar minimum could possibly impact the region of Europe in general. One thing they have been researching is information from Lake Maar to see how the sediment in the lake correlates to the solar minimum....


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
