Receding Ice, Rising Oceans. Our future in glacial decline: http://www.astrobio.net/index.php?option
Source: www.astrobio.net
Astrobiology Magazine's climate blog, The Hot Zone, recently discussed how receding glaciers could have catastrophic consequences for Earth's climate. Increasing loss of glacial ice will lead to increasing water levels in the oceans. Ultimately, these changes could profoundly affect the biosphere.

A census of 500 stars has successfully linked the 'lithium mystery' observed in our sun to the presence of planetary systems. The study shows that sun-like stars with planetary systems lack lithium, and could help astronomers identify more stars that host planets.

Some scientists believe that a relatively wet and warm ancient Mars may have been a second location for life. However, Mars did not end up as a planet filled with the multitude of life we see on Earth. NASA's new Mars orbiter, MAVEN, may help astrobiologists understand why.
