Climate Science Boost With Tropical Aerosols Profile
2013-08-02 12:59:57

CSIRO The seasonal influence of aerosols on Australia's tropical climate can now be included in climate models following completion of the first long-term study of fine smoke particles generated by burning of the savanna open woodland and grassland. Australia's biomass burning emissions comprise about eight per cent of the global total, ranking third by continent behind Africa (48 per cent) and South America (27 per cent). Lead researcher, CSIRO's Dr Ross Mitchell, said fine particles...

ALEXANDRIA, Va., July 31, 2013 /PRNewswire-USNewswire/ -- A recent report from the Environmental Protection Agency (EPA) heralded a slight decrease in U.S. greenhouse gas emissions in 2011. However, the drop from 2010 was just 1.6 percent - and emissions since 1990 have actually risen by 8.4 percent. A July report from the Earth Policy Institute found that fossil fuel emissions have risen by 2.6 percent each year since 2010, "hitting an all-time high of 9.7 billion tons of carbon in...

Polar Pool Not Extreme
2013-07-31 11:23:48

Brett Smith for redOrbit.com - Your Universe Online Last week, pictures from the North Pole Experimental Observatory (NPEO) showed the North Pole seemingly covered by a sea of water, but according to a statement from the project's principal investigator, conditions in the Arctic are typical for this time of year and viewing the images is all a matter of perspective. "Every summer when the sun melts the surface the water has to go someplace, so it accumulates in these ponds," said Jamie...

Coastal American Cities Threatened By Sea-Level Rise
2013-07-31 08:55:40

Michael Harper for redOrbit.com - Your Universe Online Boston, Miami, New York and more than 1,700 other coastal American cities are facing a greater risk from rising sea levels than had previously been estimated. A new study published in the Proceedings of the National Academy of Sciences (PNAS) claims at least 316 American cities will one day be overtaken by the sea if pollution continues to grow as it has been. More than 1,400 other cities will be "locked-in" by rising sea...

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....

Methane Release From Earthquakes Feeds Global Warming
2013-07-29 11:15:00

Michael Harper for redOrbit.com - Your Universe Online In 1945 an 8.1 magnitude earthquake hit the northern Arabian Sea which released 7.4 million cubic meters of methane into the ocean and atmosphere. Now a team of scientists from the MARUM Institute at the University of Bremen, the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research, and the ETH Zurich have concluded a study on this earthquake and believe similar temblors are also adding to the release of...

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...

WASHINGTON, July 24, 2013 /PRNewswire-USNewswire/ -- NASA scientists and an international team of researchers have found tropical ecosystems can generate significant carbon dioxide when temperatures rise, unlike ecosystems in other parts of the world. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The researchers discovered a temperature increase of just 1 degree Celsius in near-surface air temperatures in the tropics leads to an average annual growth rate of...

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...

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...

Impact Of Growing Degree Days For Baltimore In March
2013-01-13 08:26:45

Growing Degree Days are another huge part of our lives even though we may not deal with them directly. Growing degree days have to deal with the growing of fruits and vegetables along with other various crops that are grown throughout the United States for our personal use. As we examine the Baltimore Maryland area we can see how the impacts of a normal, El-Nino and La-Nina cycle have an impact on just the one month of March. These numbers are based on 50F which is the base number used for...

Climate Impact On Your Budget For Bismarck, North Dakota
2012-09-18 13:29:03

If you live in or around Bismarck North Dakota the graph shows you what you can roughly expect when it comes to heating and cooling your house during the ENSO Phases. Bismarck North Dakota, with its northern latitude, does have an impact on what type of heating and cooling it sees. During an Normal Phase the HDD for the region hits about 1348 on average. When the region enters into an El-Nino they can expect the amount of HDD’s to decrease to around 970 which really helps cut down on the...

ENSO Effects On Ocean Waters

The above graph highlights how the ENSO has an impact on water temps. Northern Gulf of Mexico during EL-Nino: The first part of March during this EL-Nino cycle saw water temps in the 56-60F range, while the 8-14th saw water temps warm to the 60-64F range. By the third week of March temps had maintained 60-64F. The last week of March the temps dropped back to around 56-60F. Northern Gulf of Mexico during LA-Nina: The first week of March saw water temps approach the 70-72F range, by the...

Honolulu is located in the Pacific Ocean and has a mostly marine time climate. Honolulu has a pretty consistent temperature average from month to month. This is a look at the La-Nina impacts on the local area. January 2010: For the month of January it is typical to see average high temps in the 80’s while overnight lows drop into the 70’s. During the El-Nino event January temps were 60% of the month at the normal, while 40% of the month was marked with above temps and 0% of the month...
