Climate Predictions Could Take Some Clues From The Pliocene Epoch
2013-04-04 06:51:19

redOrbit Staff & Wire Reports - Your Universe Online Temperature patterns during Earth´s last prolonged global “hot spell” some 5.3 million to 2.6 million years ago differed markedly from those of modern times, suggesting current climate models may need to be adjusted to improve future predictions, according to a study published this week in the journal Nature. The Earth was warmer during that time - known as the Pliocene Epoch - than it is today, and had higher...

Simulating Climate Change Using New Technique
2013-03-05 13:13:13

Brown University Statistical physics offers an approach to studying climate change that could dramatically reduce the time and brute-force computing that current simulation techniques require. The new approach focuses on fundamental forces that drive climate rather than on “following every little swirl” of water or air. And yes, there´s an app for that. Scientists are using ever more complex models running on ever more powerful computers to simulate the earth´s...

Role Of Statistics In Climate Change Research Investigated
2013-02-16 09:47:29

redOrbit Staff & Wire Reports — Your Universe Online Climate change is a range of potential events that have a better or worse probability of occurring, and statistics could be a useful tool in helping people better understand how their actions could be adversely affecting the planet, according to new research presented on Friday. The general public´s aversion to statistical thinking and probability is one of the factors that has prevented the implementation of...

Study Highlights Complex Interplay Between Global Warming And Rainfall
2013-01-31 09:51:24

April Flowers for redOrbit.com - Your Universe Online An international group of scientists has shown that global warming from greenhouse gases affects global rainfall patterns differently than global warming from solar heating. Using computer model simulations, the research team showed that global rainfall has increased less over the present-day warming period than during the Medieval Warm Period between 950 and 1250 AD despite the fact that temperatures today are higher than...

Climate scientists are still grappling with one of the main questions of modern times: how high will global temperatures rise if the atmospheric concentration of carbon dioxide doubles. Many researchers are now turning to the past because it holds clues to how nature reacted to climate change before the anthropogenic impact. The divergent results of this research, however, have made it difficult to make precise predictions about the impact of increased carbon dioxide on future warming. An...

At the end of the 21st century, the temperature in the Baltic Sea will be higher and the salt content lower than at any time since 1850. If no action is taken to alleviate the effects of climate change, there may be major consequences for the marine environment. "This is the first time that anyone has taken a detailed look at how climate models and individual factors combine to affect a specific region. This makes this project unique," says Jonathan Havenhand from the Department of...

Climate Models Work For Mars Too
2012-10-17 10:56:49

Lee Rannals for redOrbit.com - Your Universe Online According to a new study, scientific modeling methods that predicated climate change on Earth can also be used on Mars as well. Researchers from Planetary Science Institute in Tucson report they have found that an unusual concentration of glacial features on Mars matches predictions made by global climate computerized models, in terms of age and location. "Some public figures imply that modeling of global climate change on Earth is...

MAGIC Launches For Yearlong Climate Study
2012-10-01 16:21:46

Climate instruments mounted aboard the Horizon Spirit container ship begin taking data A Horizon Lines container ship outfitted with meteorological and atmospheric instruments installed by U.S. Department of Energy (DOE) scientists from Argonne National Laboratory and Brookhaven National Laboratory will begin taking data today for a yearlong mission aimed at improving the representation of clouds in climate models. The study, a collaborative effort between DOE´s Atmospheric Radiation...

Space Mirrors Won't Fix Climate Change
2012-06-06 12:00:59

Michael Crumbliss for redOrbit.com Geoengineering is a field of study that proposes techniques to reduce the amount of solar radiation reaching the Earth's surface. Methods range from mimicking the effects of large volcanic eruptions by releasing sulphur dioxide into the atmosphere to deploying giant mirrors in space. Scientists have proposed these sunlight-reflecting solutions as last-ditch attempts to halt global warming. A new study used climate models developed by the UK Met...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
