Researchers Find Cooling Effect In Warming Arctic lakes
2014-08-07 03:47:42

University of Minnesota Scientists have known for a while that warming global temperatures are causing Arctic lakes to release methane, a potent greenhouse gas that leads to even more warming. In a new study published in the journal Nature, a team of researchers including U of M researcher Jacques Finlay, found that Siberian lakes have actually pulled more greenhouse gasses from the atmosphere than they have released into it since the last Ice Age, causing an overall slight cooling...

isotope anomalies in atmospheric sulfates

Susan Brown, UC San Diego Anomalous isotopes trace Earth’s ancient atmosphere, past El Niño events and future climate Sulfur signals in the Antarctic snow have revealed the importance of overlooked atmospheric chemistry for understanding climate, past and future. Eruptions of huge volcanoes, the disruptive weather pattern known as El Niño, and a fire season from hell each left distinctive chemical marks in layers of snow excavated near the South Pole, researchers from the...

pacific trade winds
2014-08-04 05:15:20

redOrbit Staff & Wire Reports - Your Universe Online Climate scientists have finally solved the mystery as to why the equatorial Pacific trade winds, which were expected to get weaker due to increasing greenhouse gas levels, have actually gotten stronger in recent years. For more than a decade, experts have wondered why the trade winds have behaved in contrast to climate models and become supercharged since the early 1990s. The phenomenon, according to a team of US and Australian...

ocean acidification risk index

NOAA Ocean acidification is driving changes in waters vital to Alaska’s valuable commercial fisheries and subsistence way of life, according to new NOAA-led research that will be published online in Progress in Oceanography. Many of Alaska’s nutritionally and economically valuable marine fisheries are located in waters that are already experiencing ocean acidification, and will see more in the near future, the study shows. Communities in southeast and southwest Alaska face the...

NCAR/UCAR The world faces a small but substantially increased risk over the next two decades of a major slowdown in the growth of global crop yields because of climate change, new research finds. The authors, from Stanford University and the National Center for Atmospheric Research, say the odds of a major production slowdown of wheat and corn, even with a warming climate, are not very high. But the risk is about 20 times more significant than it would be without global warming, and it...

Oregon State University Scientists have long been concerned that global warming may push Earth's climate system across a "tipping point," where rapid melting of ice and further warming may become irreversible -- a hotly debated scenario with an unclear picture of what this point of no return may look like. A newly published study by researchers at Oregon State University probed the geologic past to understand mechanisms of abrupt climate change. The study pinpoints the emergence of...

What Does Data From Google Trends Tells About Our Climate Change Fears?
2014-07-18 03:43:45

Springer Political ideology, education levels affect when people search for climate information Republicans search the Net for information about the weather, climate change and global warming during extremely hot or cold spells. Democrats google these terms when they experience changes in the average temperatures. These are some of the surprising findings from a study by Corey Lang of the University of Rhode Island in the US, published in Springer’s journal Climatic Change. He tracked...

Arctic Lakes Soak Up More Greenhouse Gases Than They Emit: Study
2014-07-18 03:19:15

University of Alaska Fairbanks New University of Alaska Fairbanks research indicates that arctic thermokarst lakes stabilize climate change by storing more greenhouse gases than they emit into the atmosphere. Countering a widely-held view that thawing permafrost accelerates atmospheric warming, a study published this week in the scientific journal Nature suggests arctic thermokarst lakes are 'net climate coolers' when observed over longer, millennial, time scales. "Until now, we've...

New Sea Level Threat Created From Changing Antarctic Winds
2014-07-07 03:55:30

Australian Research Council's Centre of Excellence for Climate System Science New research shows projected changes in the winds circling the Antarctic may accelerate global sea level rise significantly more than previously estimated. Changes to Antarctic winds have already been linked to southern Australia’s drying climate but now it appears they may also have a profound impact on warming ocean temperatures under the ice shelves along the coastline of West and East Antarctic....

Greenland Ice Sheet Collapse Linked To Sea Level Rise 400,000 Years Ago: Study
2014-06-26 03:26:40

Oregon State University A new study suggests that a warming period more than 400,000 years ago pushed the Greenland ice sheet past its stability threshold, resulting in a nearly complete deglaciation of southern Greenland and raising global sea levels some 4-6 meters. The study is one of the first to zero in on how the vast Greenland ice sheet responded to warmer temperatures during that period, which were caused by changes in the Earth's orbit around the sun. Results of the study,...

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...

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...

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...
