Start Preparing Now!

clipped from wattsupwiththat.com Forget global warming and 2012, the real worry is a solar system gravity death match between Sol and Gliese 710. Movement of an orange dwarf star with a mass of about half that of the Sun will eventually bring it right to the solar system, stellar data analysis indicates. The Gliese 710 from the constellation Serpens Cauda is due to arrive in about 1.5 million years, and has an 86 per cent probability of passing through the Oort Cloud, says Vadim Bobylev at the Pulkovo Astronomical Observatory in St. Petersburg. The prediction is based on analysis of data from the European Space Agency’s Hipparcos astrometric spacecraft, which measured velocities of almost 120,000 stars in the early 1990s, as well as some recent data. Bobylev analyzed the measured movements of about 35,000 stars in our neighborhood in the time interval from 2 million years in the past to 2 million years in the future.

But, Hmmm... Even I have to admit the probability of the ice caps melting by then rises from 0.00000% to maybe 2 or even 3%. So what do I get busy and exercise my precautionary principle about?
