Earth's Climatic History Was Written In Dust
2014-01-25 05:28:19

April Flowers for redOrbit.com - Your Universe Online Polarstern, a research icebreaker, returned from the South Pacific in 2010 with a scientific treasure. The treasure, described in a recent issue of Science, consisted of ocean sediments from a previously almost unexplored part of the South Polar Sea. To geological history researchers, these inconspicuous mud samples are a valuable archive from which they can reconstruct the climatic history of the polar areas over many years of...

North America has been experiencing an onslaught of brutal winter weather, with massive amounts of snow, ice, and record low temperatures. As we look ahead to continued severe weather, here are some winter survival tips from Topical BioMedics, Inc., to help you get through it safely and in the best of health. Rhinebeck, NY (PRWEB) January 24, 2014 North America has been under siege by an onslaught of brutal winter weather, with massive amounts of snow, ice, and frigid temperatures. These...

Earth’s CO2 And Climate Stabilized By Ancient Forests
2014-01-24 12:38:58

European Geosciences Union UK researchers have identified a biological mechanism that could explain how the Earth’s atmospheric carbon dioxide and climate were stabilized over the past 24 million years. When CO2 levels became too low for plants to grow properly, forests appear to have kept the climate in check by slowing down the removal of carbon dioxide from the atmosphere. The results are now published in Biogeosciences, an open access journal of the European Geosciences Union (EGU)....

redOrbit Meteorologist Joshua Kelly Weather Forecast for January 23, 2014 11AM: Arctic high pressure is sliding southward out of the Northern Plains creating a weak boundary ahead of it. Today’s mess will be ahead of this boundary. There will be snow showers over the Great Lakes and a winter mess over the Gulf Coast and Eastern Texas. The Western US will be dry and mild again today. 11PM: The boundary will hit the Gulf of Mexico tonight. Look for this to be the focus of a major...

Climate Change In Antarctica Partially Driven By Warming In The North And Tropical Atlantic Ocean
2014-01-23 04:26:22

April Flowers for redOrbit.com - Your Universe Online A team of New York University climatologists has concluded that the gradual warming of the North and Tropical Atlantic Ocean is adding to climate change in Antarctica. The conclusions rely on more than three decades of atmospheric data and reveal new ways in which Antarctic climate change is affected by distant regional conditions. "Our findings reveal a previously unknown—and surprising—force behind climate change that is...

Association persists at levels of exposure below current European limits Long term exposure to particulate matter in outdoor air is strongly linked to heart attacks and angina, and this association persists at levels of exposure below the current European limits, suggests research conducted at the Department of Epidemiology in Rome, Italy and published on bmj.com today. The results support lowering of the EU limits for particulate matter air pollution. Ambient particulate matter air...

Impact Of El Niño On Continental Evaporation
2014-01-22 12:05:08

ESA As global temperatures gradually increase, more water is expected to evaporate into the atmosphere. But using satellite data, scientists have discovered that El Niño-induced droughts have caused global declines in evapotranspiration despite rising temperatures. Terrestrial evaporation, or evapotranspiration, is the transfer of water from soil and vegetation into the atmosphere. It’s a critical component of the global water cycle and, in recent years, it has gained increased...

redOrbit Meteorologist Joshua Kelly Weather Forecast for January 22, 2014 11AM: Low pressure will push out to sea allowing the East Coast to begin digging out from all the snow. Another strong cold high pressure will settle in over the Gulf of Mexico bringing more cold weather to the region. There is a second Arctic high moving through the Northern Plains and Rockies bringing with it yet more cold weather along with a few snow showers over Western Montana. 11PM: Low pressure will...

2013 Seventh Warmest Year On Record
2014-01-21 12:42:19

[ Watch The Video: Six Decades Of A Warming Earth ] Lee Rannals for redOrbit.com - Your Universe Online NASA's Goddard Institute for Space Studies (GISS) in New York found that 2013 tied 2009 and 2006 for the seventh warmest year since 1880. GISS analyzes global surface temperatures and released an updated report on Tuesday on the 2013 temperatures from around the world. According to the report, the average temperature last year was 58.3 degree Fahrenheit, which is about 1.1 degrees...

WASHINGTON, Jan. 21, 2014 /PRNewswire-USNewswire/ -- NASA scientists say 2013 tied with 2009 and 2006 for the seventh warmest year since 1880, continuing a long-term trend of rising global temperatures. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) With the exception of 1998, the 10 warmest years in the 134-year record all have occurred since 2000, with 2010 and 2005 ranking as the warmest years on record. NASA's Goddard Institute for Space Studies (GISS) in New...

Urban Heat Island
2013-04-02 15:35:21

An urban heat island (UHI) is a metropolitan area that is drastically warmer than its surrounding rural areas because of human activities. The phenomenon was first looked into and described by Luke Howard during the 1810s, although he wasn’t the one to name the phenomenon. The difference in temperature is normally bigger at night as opposed to during the day, and it most obvious when winds are weak. Seasonally, UHI is seen during the summer and the winter. The key cause of the urban heat...

Desertification
2013-04-02 09:46:56

Desertification is a form of land degradation in which a comparatively dry land area becomes more and more arid, normally losing its bodies of water along with its wildlife and vegetation. This is a result of a variety of factors, such as climate change and human activities. Desertification is an important global, ecological, and environmental issue. There is substantial controversy over the proper definition of the term “desertification”. The most broadly accepted of these is that of...

Climate Change
2013-04-01 11:05:27

Climate change is a substantial and lasting change in the statistical distribution of weather patterns over periods of time ranging from decades to millions of years. It might be a change in the average weather conditions, or in the distribution of weather around the average conditions. Climate change is a result of factors that include oceanic processes, biotic processes, variations in solar radiation received buy Earth, volcanic eruptions, and plate tectonics, and human induced alterations...

Weather Model Discussion:  How To Use Surface Dew-points For Weather Forecasting Purposes
2013-01-29 08:53:47

Surface Dew-points can play a huge role in weather forecasting. The first such role is that it helps determine the amount of moisture in the atmosphere for a given point. If we look at the current dew-point map above from January 28, 2013 we can note several things of interest. First, if we look at where the black circle is around the number 70, we can make note that this air right off the coast of Texas is at a dew point of 70F. The temperature outside must be above 70F, because the...

Weather Education - Air Mass Thunderstorms
2013-01-13 10:30:47

Air mass thunderstorms are found in marine time tropical air. In short they are also known as MT Thunderstorms. Air mass thunderstorms represent what is known as the common three stage thunderstorm development. This means that an air mass thunderstorm goes through the stages of Cumulus which is represented by the updrafts only being present; secondly it moves into the mature stage where it has both updrafts and downdrafts; finally it goes into the dissipating stage where you see only the...
