Climate change helps Alaskan grow organic food on the tundra

Between fighting wildfires and rerouting the Iditarod, Alaska has had a tough time with climate change. But at least there’s one good outcome: local food. In Bethel, a town in southwestern Alaska, farmer Tim Meyers is taking advantage of rising temperatures to grow food in the previously inhospitable tundra. NPR reports: At the 15-acre organic farm, which has been operating for more […]

Heat is heading for new extremes

Heatwaves that used to arrive once every 20 years or so could become annual events by 2075 across almost two-thirds of the planet’s land surface – if humans go on burning ever more fossil fuels and releasing ever more greenhouse gases. Claudia Tebaldi, visiting scientist at the US National Center for Atmospheric Research, and Michael Wehner, senior staff scientist at […]

Although current global food production is sufficient to feed everyone, the number eating less than the minimum the human body needs—an average 2,100 calories a day for adults—now grows by more than ten million a year, mostly in the poorest nations. Countries with unstable food […]

A new water world

Saturn’s ice-covered moon Enceladus could harbor a warm-water ocean beneath its frozen surface, opening up new possibilities for life beyond Earth. Enceladus has fascinated astronomers since 2005, when NASA’s Cassini probe caught geysers on the moon’s south pole spewing out plumes of salty water. Water that is thought to have originated in an ocean buried beneath the moon’s 25-mile-thick ice […]

Destroying Antarctica While Attempting To Save It

Destroying Antarctica

Are the scientists working to save Antarctica’s fragile ecosystem inadvertently contributing to its destruction? Could they possibly be Destroying Antarctica? A new study has linked a chemical used in flame-retardants—called polybrominated diphenyl ethers (PBDEs)—that is contaminating the Antarctic environment to Australia’s Casey research station. Researchers found that dust and treated wastewater at the station contained PBDEs and another chemical that […]
