Solar Flare 2013: Intense Sun Eruption Aimed At Earth, Scientists Say

Huffington Post - February 10, 2013 (Updated February 11, 2013) - Tariq Malik

A long-lasting solar flare erupted from the sun early Saturday (Feb. 9), triggering an intense sun eruption aimed squarely at Earth. The solar storm, however, should not endanger satellites or astronauts in space, but could amplify auroras on Earth, NASA says. The solar eruption —called a coronal mass ejection —occurred at 2:30 a.m. EST (0730 GMT) on Saturday during a minor, but long-duration, flare. It hurled a wave of charged particles at Earth at speeds of about 1.8 million miles per hour (nearly 2.9 million km/h).

Coronal mass ejections, or CMEs, are eruptions of charged solar material that fling solar particles out into space. When aimed at Earth, they can reach the planet between one and three days later, and cause geomagnetic storms when they interact with the planet's magnetic field. They can also amplify the northern and southern lights displays over the Earth's poles.

"In the past, CMEs at this strength have had little effect," NASA officials said in a statement. "They may cause auroras near the poles but are unlikely to disrupt electrical systems on Earth or interfere with GPS or satellite-based communications systems."

Cuba, Too, Reports Powerful Meteorite Explosion

Associated Press - February 16, 2013

 

HAVANA (AP) -- Cuba apparently experienced a phenomenon similar to but smaller than the meteorite that detonated over Russia this week, island media reported, with startled residents describing a bright light in the sky and a loud explosion that shook windows and walls.

There were no reports of any injuries or damage such as those caused by the Russia meteorite, which sent out shockwaves that hurt some 1,200 people and shattered countless windows.

In a video from a state TV newscast posted on the website CubaSi late Friday, unidentified residents of the central city of Rodas, near Cienfuegos, said the explosion was impressive.

On Heels of Russia Meteor Explosion, San Francisco Bay Area Residents Report Fireball Sighting

washingtonpost.com - Associated Press - February 16, 2013

SAN FRANCISCO — Hours after a meteor exploded over Russia and injured more than 1,000 people and an asteroid passed relatively close to Earth, residents in California reported seeing an unusual flash of light over the San Francisco Bay area that left many startled and thrilled.

Based on reports, the light streaking in the Northern California sky was a sporadic meteor, or fireball, and not a major event, said Mike Hankey, operations manager for the American Meteor Society, based in Genesee, N.Y. The group recorded at least 35 reports of the event, he said.

Meteor Shower Over Russia Sees Meteorites Hit Earth

smh.com.au - The Sydney Morning Herald - February 15, 2013

More than 1000 people were injured when a meteorite shot across the sky and exploded over central Russia on Friday, sendingfireballs crashing to Earth, shattering windows and damaging buildings.

People heading to work in Chelyabinsk heard what sounded like an explosion, saw a bright light and then felt a shockwave, according to a Reuters correspondent in the industrial city 1500 kilometres east of Moscow.

Climate Change’s Links to Conflict Draws UN Attention

By Flavia Krause-Jackson - Feb 14, 2013 8:30 PM MT - Bloomberg News

Members of the United Nations Security Council in New York met with Joachim Schellnhuber, director of the Potsdam Institute for Climate Impact Research, who presented a number of scenarios to show the connection between climate change and global security challenges.

Climate change is a “reality that cannot be washed away,” according to notes prepared for diplomats at today’s session. “There is growing concern that with faster than anticipated acceleration, climate change may spawn consequences which are harsher than expected.”

Topics ranged from Hurricane Sandy, to fossil-fuel deposits, to glacial melting and how the seeds of conflict, unrest, and revolution are being sewn.

Transparency in Supply Chains: A Convergence of Possibilities

csi.gsb.stanford.edu - Kriss - February 4, 2013

Where do the products we buy come from and how do we know that their production doesn’t leave a wake of environmental damage or exploited workers? Even brands we think we trust are often linked to suppliers with questionable or downright abusive practices, as exemplified in the November factory fire in Bangladesh, where 112 workers were killed at a factory that supplied Walmart, Sears and even the U.S. Marine Corps, though all claim they had no idea that apparel produced there was destined for their stores.

Global supply chains are complex and opaque, with many layers of suppliers, distant and inconsistent regulatory environments, and intermittent and sometimes unreliable audits and reporting.

New Era of Food Scarcity Echoes Collapsed Civilizations (Adapted from Full Planet, Empty Plates: The New Geopolitics of Food Scarcity by Lester R. Brown)

Earth Policy Institute - Book Byte - February 7, 2013

In Full Planet, Empty Plates: The New Geopolitics of Food Scarcity, Lester Brown explains that "The world is in transition from an era of food abundance to one of scarcity." 

With the demand for grain increasing and the supply of grain decreasing, food prices are rising and hunger is spreading.  "On the demand side of the food equation, population growth, rising affluence, and the conversion of food into fuel for cars are combining to raise consumption by record amounts. On the supply side, extreme soil erosion, growing water shortages, and the earth’s rising temperature are making it more difficult to expand production."

"Food shortages undermined earlier civilizations. The Sumerians and Mayans are just two of the many early civilizations that declined apparently because they moved onto an agricultural path that was environmentally unsustainable ... We, too, are on such a path."

"The bottom line is that it is becoming much more difficult for the world’s farmers to keep up with the world’s rapidly growing demand for grain ... We are entering a time of chronic food scarcity, one that is leading to intense competition for control of land and water resources—in short, a new geopolitics of food."

Recent Changes in the Ventilation of the Southern Oceans

sciencemag.org - Darryn W. Waugh1,Francois Primeau2,Tim DeVries3,Mark Holzer4 - February 1, 2013

Abstract

Surface westerly winds in the Southern Hemisphere have intensified over the past few decades, primarily in response to the formation of the Antarctic ozone hole, and there is intense debate on the impact of this on the ocean's circulation and uptake and redistribution of atmospheric gases. We used measurements of chlorofluorocarbon-12 (CFC-12) made in the southern oceans in the early 1990s and mid- to late 2000s to examine changes in ocean ventilation. Our analysis of the CFC-12 data reveals a decrease in the age of subtropical subantarctic mode waters and an increase in the age of circumpolar deep waters, suggesting that the formation of the Antarctic ozone hole has caused large-scale coherent changes in the ventilation of the southern oceans.

Detecting Ozone- and Greenhouse Gas–Driven Wind Trends with Observational Data

sciencemag.org - Sukyoung Lee1,Steven B. Feldstein1 - February 1, 2013

Abstract

Modeling studies suggest that Antarctic ozone depletion and, to a lesser degree, greenhouse gas (GHG) increase have caused the observed poleward shift in the westerly jet during the austral summer. Similar studies have not been performed previously with observational data because of difficulties in separating the two contributions. By applying a cluster analysis to daily ERA-Interim data, we found two 7- to 11-day wind clusters, one resembling the models' responses to GHG forcing and the other resembling ozone depletion. The trends in the clusters' frequency of occurrence indicate that the ozone contributed about 50% more than GHG toward the jet shift, supporting the modeling results. Moreover, tropical convection apparently plays an important role for the GHG-driven trend.
