Scripps Institute of Oceanography projects that next month its monitoring station will for the first time measure CO2 at 400 parts per million.
Atmospheric CO2 has risen from 280 parts per million before the Industrial Revolution. 400 ppm is an arbitrary milestone that we'll blow right past on our way to 450 ppm within a few decades. This is an unprecedentedly fast rate of increase and it's getting faster. Not all measuring stations are exactly the same: A NOAA station in the Arctic measured CO2 at 400 ppm last year.

Paraglider survives 32,000ft fall.
A German paragliding champion named Ewa Wisnierska
was "sucked into a storm that pulled her higher than Mount Everest." She "soared skywards," and was soon "covered in ice" as she "battled hailstones the size of oranges," becoming one with the weather. "I could see the Earth coming," she later said, "wow, like Apollo 13
– I can see the Earth."

Stormy Space Weather Takes a Toll on Ozone
A new study confirms a long-held theory that large solar storms rain electrically charged particles down on Earth's atmosphere and deplete the upper-level ozone for weeks to months thereafter. Said Charles Jackman, a researcher at NASA Goddard Space Flight Center's Laboratory for Atmospheres and lead author of the study: "[W]hen these solar proton events occur you can see immediately a change in the atmosphere, so you have a clear cause and effect."

Scientists discover possible microbe from space.
Scientists has recovered microorganisms in the upper reaches of the atmosphere that may have originated from outer space. The living bacteria, are unlike any known on Earth, but the astrobiologists want to keep the details under wraps until they are absolutely convinced that these are extraterrestrial. Do not adjust your set...
