Leading Florida-based scientific researchers released two new studies today, including a Florida State University report finding that climate change will cause significant impacts on Florida's coastlines and economy due to increased sea level rise.

A second study by researchers at Florida Atlantic University recommends that the state of Florida adopt a series of policy programs aimed at adapting to these large coastal and other impacts as a result of climate change. Key findings of the FAU report were included just this week by Florida Gov. Charlie Crist's Climate and Energy Action Team when it adopted the "Adaptation" section of its final report.

"The impacts of climate change on Florida's coasts and on our economy will be substantial, persistent and long-term, even under our conservative estimates," said Julie Harrington, director of the Center for Economic Forecasting and Analysis at FSU. "Should, as many models predict, sea level rise, and hurricane strength and other factors become more extreme, much greater economic impacts will occur along many parts of Florida's coast in this century."

The second new study, by researchers at FAU, focused on state adaptation policies needed as Florida faces the impacts of climate change.

"The goal of our study is to help the state of Florida adapt, in the most effective way possible, to climate change impacts that are now inevitable," said Jim Murley, director of Florida Atlantic University's Center for Urban and Environmental Solutions and leader of the study. "These approaches must be comprehensive and strategic, not piecemeal and episodic. Governor Crist and other leaders have rightly identified adapting to climate change as one of the state's greatest challenges -- we look forward to working with the state to protect our people, natural splendor, and economic livelihood. There is real work to be done."

Three more bodies were discovered over the weekend in areas of Texas ravaged by Hurricane Ike, increasing the storm's toll to 67 deaths nationally.

Gail Ettenger made her last phone call at 10:10 p.m. She was trapped in her Bolivar Peninsula bungalow with her Great Dane, Reba. A drowning cat cried outside. Her Jeep bobbed in the seawater surging around her home.

Black bears that live around urban areas weigh more, get pregnant at a younger age, and are more likely to die violent deaths, according to a study by the Wildlife Conservation Society (WCS).

The study, published in the Fall 2008 issue of the journal Human-Wildlife Conflicts, tracked 12 bears over a 10-year period living in urban areas around Lake Tahoe, Nevada and compared them to 10 "wildland" bears that lived in outlying wild areas. The authors found that bears in urbanized areas weighed an average of 30 percent more than bears in wild areas due to a diet heavily supplemented by garbage.

The authors believe that because the bears weigh more they are giving birth at an earlier age - on average when they are between 4-5 years old, as compared to 7-8 years for bears in wild areas. Some urban bears even reproduced as early as 2-3 years of age around Lake Tahoe.

Urban bears also tend to die much younger due mostly to collisions with vehicles, according to the study. All 12 urban bears tracked by the researcher were dead by age 10 due to vehicle collisions, while six of the wildland bears still survived. Bear cubs in urban areas also had dramatically higher mortality rates due mainly to vehicle collisions.

Cancun, Mexico - Dainty blue fish dart around coral shaped like moose antlers near the Mexican resort of Cancun, but sickly brown spots are appearing where pollution threatens one of the world's largest reefs.

Parts of the reef, nestled in turquoise waters, have died and algae -- which feed on sewage residues flowing out of the fast-growing resort city -- has taken over.

Coral reefs like Chitales, near the northern tip of a Caribbean reef chain stretching from Mexico to Honduras, are dying around the world as people and cities put more stress on the environment.

Climate change alone could trigger a global coral die-off by 2100 because carbon emissions warm oceans and make them more acidic, according to a study published in December.

But local environmental problems like sewage, farm runoff and overfishing could kill off much of the world's reefs decades before global warming does, said Roberto Iglesias, a biologist from UNAM university's marine sciences station near Cancun.

"The net effect of pollution is as bad or maybe worse than the effects of global warming," said Iglesias, a co-author of the study in the journal Science on how climate change affects reefs.

Human waste like that from Cancun's hotels and night spots aggravates threats to coral worldwide like overzealous fishing which hurts stocks of fish that eat reef-damaging algae.

Small white stalagmites lining caves in the Midwest may help scientists chronicle the history of the New Madrid Seismic Zone (NMSZ) - and even predict when the next big earthquake may strike, say researchers at the Illinois State Geological Survey and the University of Illinois at Urbana-Champaign.

While the 1811-12, magnitude 8 New Madrid earthquake altered the course of the Mississippi River and rung church bells in major cities along the East Coast, records of the seismic zone's previous movements are scarce. Thick layers of sediment have buried the trace of the NMSZ and scientists must search for rare sand blows and liquefaction features, small mounds of liquefied sand that squirt to the surface through fractures during earthquakes, to record past events. That's where the stalagmites come in.

The sand blows are few and far between, said Keith Hackley, an isotope geochemist with the Illinois State Geological Survey. In contrast, caves throughout the region are lined with abundant stalagmites, which could provide a better record of past quakes. "We're trying to see if the initiation of these stalagmites might be fault-induced, recording very large earthquakes that have occurred along the NMSZ," he said.

A salty haze over parts of the Gold Coast this morning has dramatically reduced visibility in some areas - while others are perfectly clear.

The Chilean volcano Chaiten has been erupting since September 23, 2008. This activity has been registered on the website, when the volcano icon turned from brown to red. A little later, magma flow was detected by the Modis fire detection system, shown by a yellow spot in the middle of the volcano symbol.

An eruption occurred at Shiveluch volcano in Russia on 25th September 2008. At 8 am local time the eruption produced an ash column 4.5 km high. The eruption was accompanied by earthquakes. There was no threat to nearby communities according to the Geophysics Service of the Russian Academy of Sciences.

Froghoppers, also known as spittlebugs, are the champion insect jumpers, capable of reaching heights of 700 mm - more than 100 times their own body length. Research published today in the open access journal BMC Biology reveals that they achieve their prowess by flexing bow-like structures between their hind legs and wings and releasing the energy in one giant leap in a catapult-like action.
