Survey Results Illuminate Threats to Giant Industry's Solvency, Plus Wider Impacts on Consumers, Businesses, Insurers' Vast Portfolios BOSTON, Sept. 1, 2011 /PRNewswire-USNewswire/ -- Only 11 of 88 major insurers surveyed recently have formal policies in place to deal with growing climate change risks, according to a major new report issued today by Ceres. The report was to have been delivered today at a conference of the National Association of Insurance Commissioners (NAIC) that was...

A New Hypothesis On Ocean Acidification
2011-08-31 06:17:11

  Since the beginning of the Industrial Revolution, the concentration of carbon dioxide in the atmosphere has been rising due to the burning of fossil fuels. Increased absorption of this carbon by the oceans is lowering the seawater pH (the scale which measures how acidic or basic a substance is) and aragonite saturation state in a process known as ocean acidification. Aragonite is the mineral form of calcium carbonate that is laid down by corals to build their hard skeleton....

  A new study, published in the journal Nature draws a correlation between El Nino weather events and civil warfare. El Nino Southern Oscillation (ENSO) happens every two to seven years and is a warming of ocean water in the western pacific that shifts across the ocean. This warming of the ocean causes the warmer air to rise, pushing away clouds and moisture changing rainfall patterns and temperatures across much of Africa, South and Southeast Asia and Australia. The correlating...

  An Update from NASA's Sea Level Sentinels: Like mercury in a thermometer, ocean waters expand as they warm. This, along with melting glaciers and ice sheets in Greenland and Antarctica, drives sea levels higher over the long term. For the past 18 years, the U.S./French Jason-1, Jason-2 and Topex/Poseidon spacecraft have been monitoring the gradual rise of the world's ocean in response to global warming. While the rise of the global ocean has been remarkably steady for most of...

Although the rain this summer has been pouring down over Denmark, most scientists agree that global temperature increases will intensify periods with summer drought already in 2075. The large scale project CLIMAITE, led by Risø DTU, has published its first synthesis paper in the renowned journal Global Change Biology, and the conclusion is perhaps a little surprising that the predicted increase in plant growth, due to more CO2 in the atmosphere is noticeably limited when...

In three decades of recording Arctic Ocean sea ice, the National Oceanographic and Atmospheric Administration (NOAA) on Monday reported that in July 2011 the sea ice hit its lowest monthly recorded level. Sea ice in the Arctic covered an average 3 million square miles during July, the lowest measurement for that month since the NOAA started keeping such records in 1979. The July 2011 figure is 81,000 square miles smaller than 2007's July record low and about 22 percent below the average for...

A Montana State University researcher who analyzed 100 years of data has found a significant link between extreme Montana weather and the ocean temperatures near Peru. Montanans who want to know what to expect from the weather should look to the Pacific Ocean in the fall or maybe find a way to chat with some Peruvian fishermen, according to Joseph Caprio, professor emeritus in MSU's Department of Land Resources and Environmental Sciences and former Montana State Climatologist. If the average...

Toxic chemicals that have been trapped in Arctic ice and snow are now being released due to global warming, according to a study published on Sunday. Researchers warn that the amount of poisons in the polar region is unknown and the release of large amounts of such poisons could "undermine global efforts to reduce environmental and human exposure to them." Those chemicals include the pesticides DDT, lindane and chlordane; and industrial chemicals PCBs and HCB. All of these are known as...

Melting ice sheets contributed much more to rising sea levels than thermal expansion of warming ocean waters during the Last Interglacial Period, a UA-led team of researchers has found By Daniel Stolte, University of Arizona Thermal expansion of seawater contributed only slightly to rising sea levels compared to melting ice sheets during the Last Interglacial Period, a University of Arizona-led team of researchers has found. The study combined paleoclimate records with computer simulations of...

Study on Jakobshavn Isbrae supports growing evidence that calving glaciers are particularly sensitive to climate change Large, marine-calving glaciers have the ability not only to shrink rapidly in response to global warming, but to grow at a remarkable pace during periods of global cooling, according to University at Buffalo geologists working in Greenland. The conclusion stems from new research on Jakobshavn Isbrae, a tongue of ice extending out to sea from Greenland's west coast. Through...

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.
