Antarctic Microbes live off Antarctic air

Life in Antarctica consists of more than penguins and seals. A rich microbial community exists on the ice, the fresh water ponds and in the soil. However, it was unclear how these organisms thrive in their habitat. Now, a team of scientists led by the University of New South Wales Sydney has discovered that microbes have a previously unknown ability to scavenge trace gases from the air to stay alive in these extreme conditions.

Arctic data shows no warming hiatus

The global warming hiatus, an apparent global warming slowdown, has puzzled scientists for a long time. Instead of an ever-rising temperature, the average global temperature seemed to go down again. New data from the Arctic, however, shows that the Arctic actually warmed six times faster than the global average and that global warming in fact didn’t slow down at all.
