Newly Discovered Microbe in Melting Tundra

A microbe recently discovered in the melting Arctic permafrost appears to be releasing vast amounts of the greenhouse gas methane, possibly speeding up climate change.

Methanoflorens stordalenmirensis “breathes out methane like we breathe out carbon dioxide,” said lead author Carmody McCalley, a scientist at the Earth Systems Research Center at the University of New Hampshire.

Methane makes up only about 9 percent of all the greenhouse gases in the atmosphere, but it can store up to 21 times more heat than carbon dioxide.

Researchers say they hope the microbic discovery will help scientists improve their simulations of future climate by providing a more accurate picture of how thawing permafrost releases greenhouse gases.

Global Temperature Extremes

The week’s hottest temperature was 112.1 degrees Fahrenheit (44.5 degrees Celsius) at Santiago del Estero, Argentina.

The week’s coldest temperature was minus 69.7 degrees Fahrenheit (minus 56.5 degrees Celsius) at Russia’s Vostok Antarctic research station.

Temperatures were tabulated from the more than 10,000 worldwide synoptic weather stations. The United Nations World Meteorological Organization sets the standards for weather observations, and provides a global telecommunications circuit for data distribution.

Roundup of Global Volcanic Activity

Turrialba (Costa Rica): A relatively large explosion occurred at the volcano last night at 23:40 local time. According to local news, the eruption lasted about 45 minutes and was accompanied by strong seismic activity, which was felt by the local population. As the eruption occurred at night, there are no visual reports.

Copahue (Chile/Argentina): Signs of unrest at the volcano have decreased and SERNAGEOMIN lowered the alert level back to yellow: Seismicity declined during the past days, the volcanic edifice showed deflation and a crater lake has reformed at the bottom of El Agrio crater. Glow from the summit, probably caused by very hot gasses, was last seen on 27 Oct (but bad weather prevented observations since).
