Update: August 16, 2013: A NASA study regarding last February's explosion of a large meteor over Siberia has revealed that the detonation of the space rock generated a massive dust cloud that circled the entire globe in only four days! The report also states that the dust cloud remained detectable in the atmosphere for as long as three months after the explosion. It has been reported that NASA's Suomi NPP Satellite was used to track the cloud, which contained hundreds of tons of dust that began to disperse into earth's atmosphere immediately after the meteor exploded with the force of fifty Hiroshima-sized atomic bombs. The dust cloud was more than likely the culprit behind the coldest temperature ever recorded in Siberia, which took place only days after the meteor event. This study should help climatologists better understand the connection between meteor/comet impact events on our planet and how these impacts can quickly initiate ice ages that can last for hundreds of thousands of years and place all of humanity in great jeopardy.
While news coverage of last week's massive meteor explosion over Russia—which injured over 1200 people, shattered windows and damaged buildings over several hundred square miles—was extensive, this [perhaps] related story was all but ignored. You can decide if it's coincidental or not.
Only a few days after the meteor exploded over the city of Chelyabinsk in Siberia on February 15, the coldest temperature ever recorded in the country took place. The temperature— -71.2°C (-96.1°F)—was recorded on February 19 in the Siberian city of Oymyakon, some 2000 miles away from Chelyabinsk. The previous record for coldest temperature in the region was -68°C (-90.4°F) set in the year 1933. [Citation: No Trick Zone]
The link between asteroid and/or comet impacts/atmospheric explosions has been noted extensively through scientific studies regarding intense climate change in the past, many which have led to mass extinction events on Earth. A [smaller] bolide meteor explosion that took place above the Asian continent in November 2010 apparently caused aberrant weather conditions throughout China and parts of Europe.

Information is also coming to light how the atmospheric meteor explosion in Russia triggered the country's nuclear defense warning system, in place to detect incoming InterContinental Ballistic Missiles (ICBM) from the United States or other threatening nations. The infrasonic waves created by the meteor's detonation high in the atmosphere over the Ural Mountains was also detected by 17 nuclear monitoring stations around the globe, including those used by the United States. The explosion has been determined to have been equivalent to 50 Hiroshima sized nuclear bombs. These same monitors also detected the detonation of a nuclear device commissioned by the rogue North Korean government only a few days prior to the "celestial event" taking place.

Of course, NASA's stance regarding the meteor explosion in Russia (and a smaller meteor explosion over Cuba less than 24-hours later) and any connection to the large 2012 DA14 asteroid that had a very close flyby with earth on the same day is strictly "coincidental". Just as the Global Warming proponents are claiming the coldest temperature ever recorded in Siberia and the meteor explosion over the same area only a few days before is also coincidental. There certainly are a great deal of coincidences taking place around the world regarding climate and geological events as of late...if you believe in coincidence...
