Coast To Coast AM - 1.6.2011 - 1/4 - Destructive Earth / Vet Health Issues

MP3 http://www.4shared.com/file/oKHoayf3/Coast_To_Coast_AM_-_162011_-_P.html Guests: Peter Ward, Joyce Riley Planetary Science: In the first half of Wednesday's show, Professor Peter Ward discussed his studies of planetary science, Earth, and its turbulent changes, as well as alien worlds. Sea level has risen 15 ft. in the last 100 hundred years, and this brings on a rise in temperatures as the oceans expand. If this continues, the next generations will be saddled with the costs of building massive sea walls in order to protect cities and infrastructure, he commented. Life on Earth began about 3.7 billion years ago, and was probably initiated through panspermia, via bacteria on meteorites from Mars, he said. "We are Martians, as far I'm concerned," Ward said, citing the work of Joseph Kirschvink at Cal Tech who noted that ribose (the backbone of RNA) comes from a desert environment, which Earth did not have back then. Ward advocated for space exploration to Saturn's moon Titan, which would be easier to land on because it has an atmosphere. Titan might contain long-chain silicon life forms, he theorized. He reported that biologist Craig Venter has produced an "alien," by tinkering with the genetic code of a bacterium. He believes Venter has entered into a dangerous arena, as such creations might eventually be weaponized. Vet Health Issues: In the latter half of the show, nurse Joyce Riley shared an update on the health problems of Gulf War vets. A lot of US soldiers in Iraq were exposed to emissions from a sulfur mine, and troops in both Afghanistan & Iraq lived near burn pits used to dispose of items like electronics and military equipment. Many of these soldiers are now suffering from respiratory ailments, she reported (related article). Riley recommended detoxification through food and diet for vets exposed to a variety of chemicals and conditions. "Hundreds of thousands of our military have been experimented upon, compromised, made ill, and died. Then they tell them that it's PTSD-- whether it is or not, that's always what they're told, which is so unfair to the troops and their families," she declaimed.

NASA Science - The Surprising Power of a Solar Storm

A recent flurry of eruptions on the sun did more than spark pretty auroras around the poles. NASA-funded researchers say the solar storms of March 8th through 10th dumped enough energy in Earth's upper atmosphere to power every residence in New York City for two years. "This was the biggest dose of heat we've received from a solar storm since 2005," says Martin Mlynczak of NASA Langley Research Center. "It was a big event, and shows how solar activity can directly affect our planet." Mlynczak is the associate principal investigator for the SABER instrument onboard NASA's TIMED satellite. SABER monitors infrared emissions from Earth's upper atmosphere, in particular from carbon dioxide (CO2) and nitric oxide (NO), two substances that play a key role in the energy balance of air hundreds of km above our planet's surface. "Carbon dioxide and nitric oxide are natural thermostats," explains James Russell of Hampton University, SABER's principal investigator. "When the upper atmosphere (or 'thermosphere') heats up, these molecules try as hard as they can to shed that heat back into space." That's what happened on March 8th when a coronal mass ejection (CME) propelled in our direction by an X5-class solar flare hit Earth's magnetic field. (On the "Richter Scale of Solar Flares," X-class flares are the most powerful kind.) Energetic particles rained down on the upper atmosphere, depositing their energy where they hit. The action produced spectacular auroras around the poles and significant1 upper atmospheric heating all around the globe. "The thermosphere lit up like a Christmas tree," says Russell. "It began to glow intensely at infrared wavelengths as the thermostat effect kicked in." For the three day period, March 8th through 10th, the thermosphere absorbed 26 billion kWh of energy. Infrared radiation from CO2 and NO, the two most efficient coolants in the thermosphere, re-radiated 95% of that total back into space. In human terms, this is a lot of energy. According to the New York City mayor's office, an average NY household consumes just under 4700 kWh annually. This means the geomagnetic storm dumped enough energy into the atmosphere to power every home in the Big Apple for two years. "Unfortunately, there's no practical way to harness this kind of energy," says Mlynczak. "It's so diffuse and out of reach high above Earth's surface. Plus, the majority of it has been sent back into space by the action of CO2 and NO." During the heating impulse, the thermosphere puffed up like a marshmallow held over a campfire, temporarily increasing the drag on low-orbiting satellites. This is both good and bad. On the one hand, extra drag helps clear space junk out of Earth orbit. On the other hand, it decreases the lifetime of useful satellites by bringing them closer to the day of re-entry. The storm is over now, but Russell and Mlynczak expect more to come. "We're just emerging from a deep solar minimum," says Russell. "The solar cycle is gaining strength with a maximum expected in 2013." More sunspots flinging more CMEs toward Earth adds up to more opportunities for SABER to study the heating effect of solar storms. "This is a new frontier in the sun-Earth connection," says Mlynczak, and the data we're collecting are unprecedented." Credit: NASA Science
