Greenland's ice sheet: Climate change outlook gets a little more dire
If temperatures reach 1.6 degrees C above preindustrial levels, the iconic ice sheet will probably tip toward irreversible loss. With climate change, temperatures have already risen 0.8 degrees C.

Solar flares: Be glad you're on Earth, not Mars (+video)
The recent solar flares provide a dramatic backdrop for a study that shows Mars gets far more of its atmosphere stripped away by solar storms than does Earth. Thank you, magnetosphere.

Marsquake? How rumblings could bolster hope for life on Mars.
If seismic activity on Mars is recent, and it can be traced to a volcano, it could mean that there is a source of heat to melt ice and provide potential habitats for simple forms of life.

Fracking study sends alert about leakage of potent greenhouse gas
A new study finds that fracking is releasing methane, a greenhouse gas, from a Colorado field at a higher rate than estimates suggested. Researchers must determine if the field is an anomaly or part of a bigger problem.

Extent of Arctic summer sea ice at record low level
New data indicates the continuation of a long-term decline in summer ice underway since at least 1979. Researchers say roughly half the decline can be attributed to global warming.

Solar storms: Two breakthroughs could lead to better warnings
The solar storms that cause blackouts and damage satelites have always been hard to predict, but two new methods of monitoring them could lead to much more accurate forecasts.

Discovery on Saturn's moon fuels speculation of alien life
Chemical data from Titan returned by NASA's Cassini spacecraft has led scientists to speculate that there are organic processes happening on the Saturnian moon's surface. But, if the data are correct, there are a lot of non-biological explanations that need to be ruled out first.

Mediterranean Sea heating up and getting saltier
An increase in ocean salinity suggests an increase in the net evaporation of the water.

NASA: Some of moon's craters may be electrified
New NASA calculations suggest that solar wind blowing across the moon's surface may electrically charge polar craters.

Time for El Niño's half brother to take a bow?
A new form of El Niño has appeared on the scene. And global warming is likely to make it more common, some researchers say.
