Latest Effects of global warming Stories
GREENBELT, Md., Dec. 7, 2010 /PRNewswire-USNewswire/ -- A new NASA computer modeling effort has found that additional growth of plants and trees in a world with doubled atmospheric carbon dioxide levels would create a new negative feedback - a cooling effect - in the Earth's climate system that could work to reduce future global warming. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The cooling effect would be -0.3 degrees Celsius (C) (-0.5 Fahrenheit (F)) globally and -0.6...
The world's oceans are facing far-reaching implications for its marine biodiversity and food security, due to changes in their chemistries not seen in more than sixty million years, according to a new study released by the United Nations on Thursday. "Environmental Consequences of Ocean Acidification," published by the UN Environmental Program (UNEP), warns that some sea organisms including coral and shellfish will have an increasingly difficult time surviving, as acidification shrinks the...
ASU study of endolithic cyanobacteria has implications for coral reefs and mussel aquacultureGeo-microbiologists from Arizona State University have solved a long-standing conundrum about how some photosynthetic microorganisms, endolithic cyanobacteria, bore their way into limestone, sand grains, mussel shells, coral skeletons and other substrates composed of carbonate.According to the lead investigator, ASU professor Ferran Garcia-Pichel, the answer to the mystery of what is "at the...
Arctic communities forced to adapt their work, diet and decision makingFive years of social science research in Canada's arctic has taught one University of Guelph geography professor a thing or two about climate change's "human face."Barry Smit is the Canada Research Chair in Global Environmental Change, and since 2005 he's studied how Arctic communities have tried to adapt to the rising temperatures caused by major shifts in global weather patterns.The human dimension of climate...
The U.S. Environmental Protection Agency (EPA) said states with coastal waters that are becoming more acidic because of carbon dioxide should list them as impaired under the Clean Water Act. The agency's memo recognizes carbon dioxide as not only an air pollutant but a water pollutant, and notes the serious impacts that ocean acidification can have on aquatic life. Ocean acidification refers to the decrease in the alkalinity of oceans, which is caused by the absorption of excess carbon...
By Yasmin Anwar, UC BerkeleyApocalyptic warnings challenge beliefs that world is just and stableDire or emotionally charged warnings about the consequences of global warming can backfire if presented too negatively, making people less amenable to reducing their carbon footprint, according to new research from the University of California, Berkeley."Our study indicates that the potentially devastating consequences of global warming threaten people's fundamental tendency to see the world...
A switch to wind energy will help reduce greenhouse gas emissions -- and reduce the global warming they cause. But there's a catch, says climate researcher Diandong Ren, a research scientist at the University of Texas at Austin in a paper appear in the AIP's Journal of Renewable and Sustainable Energy: rising temperatures decrease wind speeds, making for less power bang for the wind turbine buck.The prevailing winds in the "free" atmosphere about 1,000 meters above the ground are...
A doubling of abnormally wet or dry summer weather in the southeastern United States in recent decades has come from an intensification of the summertime North Atlantic Subtropical High (NASH), or "Bermuda High."And that intensification appears to be coming from global warming, according to a new analysis by a Duke University-led team of climate scientists.The NASH is an area of high pressure that forms each summer near Bermuda, where its powerful surface center helps steer Atlantic...
Researchers measure survival, reproduction of thousands of arctic and alpine plants over six yearsAs Earth's climate warms, species are expected to shift their geographical ranges away from the equator or to higher elevations.While scientists have documented such shifts for many plants and animals, the ranges of others seem stable.When species respond in different ways to the same amount of warming, it becomes more difficult for ecologists to predict future biological effects of climate...
While it's still hotly debated among scientists whether climate change causes a shift from the traditional form of El Nino to one known as El Nino Modoki, online in the journal Nature Geoscience, scientists now say that El Nino Modoki affects long-term changes in currents in the North Pacific Ocean.El Nino is a periodic warming in the eastern tropical Pacific that occurs along the coast of South America. Recently, scientists have noticed that El Nino warming is stronger in the Central Pacific...

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...
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...
If you live Honolulu Hawaii or the surrounding low elevation area’s this is what you can roughly expect to see with impacts of the three features below when it comes to your heating and cooling budget. The above graph shows the situations that occurred during previous phases of all three events such as normal conditions along with EL-Nino and La-Nina. During a normal cycle it is easy to see that the cooling degree days during March were around 355.5 days. During the same month of March...
El-Nino is marked with having warmer waters in the Pacific Ocean, so how can it have impacts on Austin Texas. This is a look at what occurred during an EL-Nino event as we evaluate three months of the cycle. January 2012- March 2012 La-Nina Impacts on Austin TX Climate January 2012 Normal temperatures for the month are usually around 40-60F. Examining what occurred during the month of January during an EL-Nino event the temps where average 40% of the month. While, 21% of the month...
