Q&A: Global warming talk in Fort George Island Atmospheric physicist also will talk about recent disastrous weather. Posted: June 9, 2011 - 12:00amBy Larry Hannan imageMichael Coffey wasn’t planning to focus on recent weather catastrophes in his talk today at St. George Episcopal Church on Fort George Island.

But earlier this week, Coffey, an atmospheric physicist at the National Center for Atmospheric Research in Boulder, Colo., found out his talk was being promoted with the tagline, “What on earth is happening with our weather?” So he’ll spend a little bit of time discussing the tornadoes in Missouri and Arkansas and the tsunami in Japan.

The event, open to the public, begins with a 6 p.m. reception at the church, 10560 Fort George Road. Coffey will speak and take questions at 7 p.m.

The Times-Union spoke to Coffey Wednesday morning after he arrived in Jacksonville.

Disasters 2 Arizona Towns Empty as Wildfire Approaches Power Lines

SPRINGERVILLE, Ariz. –  Fire crews worked through the night to protect several Arizona mountain communities from a growing forest fire that has forced thousands from their homes and threatens transmission lines that supply electricity as far east as Texas.

The 607-square-mile blaze, the second largest ever in Arizona, is expected to reach the power lines as early as Friday. If the lines are damaged, hundreds of thousands in parts of New Mexico and Texas could face rolling blackouts.

A perfect storm of stupid The news is full of extreme weather headlines – floods, wildfires, droughts, tornadoes – but the US still doesn’t get climate change

These two lines were written by Henry Wadsworth Longfellow in his poem “Snow-Flakes”, published in a volume in 1863 alongside his epic and better-known “The Midnight Ride of Paul Revere”. Much of the news chatter this week has been about Sarah Palin’s flubbing of the history of Revere’s famous ride in April 1775. Revere was on a late-night, clandestine mission to alert American revolutionaries of an impending British attack. Palin’s incorrect version had Revere loudly ringing a bell and shooting a gun on horseback as a warning to the British to back off.

Tsunami Sensor Detects Mysterious Background Signal in Panama ScienceDaily (June 3, 2011) — An unusual signal detected by the seismic monitoring station at the Smithsonian Tropical Research Institute’s research facility on Barro Colorado Island results from waves in Lake Gatun, the reservoir that forms the Panama Canal channel, scientists report. Understanding seismic background signals leads to improved earthquake and tsunami detection in the Caribbean region where 100 tsunamis have been reported in the past 500 years.

Ecology Biased Against Non-Native Species? June 8,2011

The authors of the Nature comments section note that assumptions that “introduced species” offer only deleterious impacts are misguided and “that human-induced impacts, such as climate change, nitrogen eutrophication, urbanization and land use change are making the native-versus-alien species dichotomy in conservation increasingly meaningless.”Often called aliens, hitchhikers or invasives, non-native species could just as easily be coined “abductees” whose transport links to activities by humans, some scientists say.
