Runaway Greenhouse Planet
2013-07-30 11:42:08

Brett Smith for redOrbit.com - Your Universe Online When a planet absorbs too much solar radiation, its atmosphere reaches a tipping point - overheating, boiling its oceans and filling with steam. The result is an uninhabitable world much like Venus. This 'runaway greenhouse' phenomenon typically occurs just inside the habitable zone orbited by planets like Earth, and a new report in Nature Geoscience indicates that reaching the tipping point may be easier than previously thought....

Diverse approaches and techniques may be the key to revealing the complex relationships between plants and wide-scale biological changes Recently, climate change, including global warming, has been a "hot" news item as many regions of the world have experienced increasingly intense weather patterns, such as powerful hurricanes and extended floods or droughts. Often the emphasis is on how such extreme weather impacts humans, from daily heat index warnings to regulating CO2 emissions. While...

Scientists Are Decoding Mechanism For Long-term Climate Fluctuations In The Atlantic
2013-07-25 10:29:13

Helmholtz Centre for Ocean Research Kiel (GEOMAR) Why does hurricane activity vary from decade to decade? Or rainfall in the Sahel region? And why are the trans-Atlantic changes frequently in sync? A German-Russian research team has investigated the role of heat exchange between ocean and atmosphere in long-term climate variability in the Atlantic. The scientists analyzed meteorological measurements and sea surface temperatures over the past 130 years. It was found that the ocean...

Variations In Earth’s Carbon Dioxide Levels Regulated By Tropical Ecosystems
2013-07-23 13:25:45

CSIRO Rising temperatures, influenced by natural events such as El Nino, have a corresponding increase in the release of carbon dioxide from tropical forest ecosystems, according to a new study out today. The study, published in the journal Proceedings of the National Academy of Sciences, found that a temperature anomaly of just 1 degree C (in near surface air temperatures in the tropics) leads to a 3.5-Petagram (billion tonnes of carbon) anomaly in the annual CO2 growth rate, on...

Causes Of A Rapid Warming In The Upper Subtropical Oceans Of The Southern Hemisphere Identified
2013-07-23 13:04:07

CSIRO They partly attribute the observed warming, and preceding cooling trends to ocean circulation changes induced by global greenhouse gas emissions and aerosols predominantly generated in the Northern Hemisphere from human activity. The research, by scientists from CSIRO and the University of NSW, was published today in Scientific Reports. Mr Tim Cowan, lead author of the study, says his group was initially interested in the three decade long cooling below the surface of the...

CIA Investigating How To Manipulate Climate Change
2013-07-19 15:51:48

Brett Smith for redOrbit.com - Your Universe Online In a move that sounds vaguely reminiscent of one of Dr. Evil's plans, the CIA is planning to investigate how humans could potentially control the global climate. The 21-month project being run by the National Academy of Sciences and partially being funded by the CIA "is intended to provide a careful, clear scientific foundation that informs ethical, legal, and political discussions surrounding geoengineering," according to...

Current Sea Level Rise
2013-04-01 10:39:21

The sea levels all around the world are rising. Current sea-level rise has the potential to affect human populations and the natural environment. Two key factors have contributed to the observed sea level rise. The first is thermal expansion: as the ocean water warms, it expands. The second is from the influence of land-based ice because of increased melting. The major store of water on land is found in the glaciers and the ice sheets. The rising of sea levels is one of several lines of...

Incoming Solar Radiation Impacts By Various Weather Cycles
2012-08-22 13:30:39

The above image looks at the month of March for the three cycles known as Normal Phase, El-Nino, and La-Nina. The data was recorded for the city of Honolulu Hawaii, during the month of March. Remember this is just data for one month during these cycles. Normal: During this cycle incoming solar activity was upwards to 48% efficient for the month, producing less than 50% of the month which is due to the large amount of daily cloud cover that is seen on the island during the early morning and...

Being a meteorologist for over thirteen years you start to take note of many things in the atmosphere and how they repeat themselves. Our Climate is no different. The definition of climate is stated as: the collective weather data in regards to moisture and temperature for over 30 years for the same location. So to better understand our climate we need to look at this. First, we have average temperatures for given places based on the 30 year average. Some years the temps are warmer or...

Incoming Solar Radiation Impacts By Various Weather Cycles

The above image looks at the month of March for the three cycles known as Normal Phase, El-Nino, and La-Nina. The data was recorded for the city of Austin Texas. Remember this is just data for one month during these cycles. Normal: During this cycle incoming solar activity was upwards to 60% efficient for the month, producing enough solar energy that only 40% of the month would have not had strong incoming radiation. EL-Nino: This phase provided the area with an extended number of...

The month of March provided a huge absence of winter with record breaking temperatures from the Canada border all the way south and eastward across the United States. Half of the United States shattered records which made the month of March, 2012 the warmest ever on record. There are a few states that did not share in the record warmth  along the west coast. They actually had cooler weather. What lead to the extreme warm temperatures during the month of March was a weather pattern built...

  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
