The permafrost melted in Siberia 130,000 years ago, a natural phenomenon caused by changes in the earth's orbit. It took thousands of years. The permafrost is melting again in Siberia, but scientists say it may only take decades or perhaps a century this time. As the permafrost melts it releases CO 2 , which accelerates the rate of warming. It is also creating giant craters. One scary concern is that microbes and viruses long buried in the permafrost, and now being exposed to the light and air, can release long dormant infectious agents like anthrax, smallpox and bubonic plague. Just last year at least 20 people were infected with anthrax (pictured) in Siberia. It's believed that reindeer corpses surfacing from the frozen tundra are infecting soil and water. Scientist estimate over a million reindeer died in northern Russia alone in the last century. Fortunately, not all bacteria can revive after being frozen, just spore- forming bacteria.
