The first-ever study of air trapped in the deep snowpack of Greenland has yielded surprising results. Current computer models had predicted that levels of carbon monoxide locked into the snowpack would be higher than those recorded in the 1950s, yet it appears that the opposite is true.

A recent paper published in the journal Atmospheric Chemistry and Physics has shown that CO levels rose slightly from 1950 until the 1970s, then declined strongly to present-day values. These findings contradict computer models that had calculated a 40 percent overall increase in CO levels over the same period.

There is earthquake activity around two supervolcanoes, one in North Korea and the other in the United States. Earthquake swarms in such areas can indicate magma movement, and scientists are studying both volcanoes. A thousand years ago the eruption of Mount Paektu in what is now North Korea was probably the largest in human history. The eruption of the Yellowstone Supervolcano would devastate the United States. In addition to these two restless supervolcanoes, large-scale earthquake activity is continuing. Like the meteor count Unknowncountry reported on earlier this week, the earthquake count has been rising worldwide for a number of years.

The Red Planet is in the news again this week: it appears that the planet which is in line for a bashing next year from Comet Siding Spring could once have supported life, as there is ice in the Martian soil. Does it support life now? There’s no evidence of natural life there, and the lack of free methane in the atmosphere suggests that not even bacteria live on Mars now. But generally dismissed and debunked features such as the Mars Face remain as a testament to the planet’s mysteries. For example, the photo accompanying this story was debunked as a ‘tiny rock’ on BadAstronomy.com and false stories that it had been ‘photoshopped,’ such as the one linked here, were widely circulated.read more
