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 […]

The drylands of the world are getting greener, and researchers think it is thanks to higher levels of carbon dioxide in the atmosphere. In a paradoxical discovery, even as landscapes become increasingly at risk of desertification, they may also look more luxuriant. Two scientists from Purdue University in Indiana, US, and a researcher in Saudi Arabia report in the journal […]

The temporary housing settlements of Williston, N.D., might seem like an unlikely haunt for archaeologists. Nonetheless, a team of “punk archaeologists” are there, finding the history in the present by peering into the lives of people at the heart of North Dakota’s oil industry. Thanks to the lucrative nature of the “Bakken boom” — the ongoing oil drilling in North […]

Tropical forests account for a third of the total carbon fixed by photosynthesis. Lianas’ increasing abundance may be driven by changing climate, increased disturbance or by more severe seasonal drought. By reducing the ability of tropical forests to accumulate and store carbon released through burning fossil fuels, lianas could cause a positive feedback loop, accelerating climate change. “This study has […]

The Pine Island Glacier has been melting due to a volcano heat source that researchers have found underneath the glacier in Antarctica. The volcanic activity was first noticed in 2007 and then verified in 2014. This volcanic activity was discovered by some scientists at the University of Rhode Island’s Graduate School of Oceanography. From January to March of 2014 scientists […]

The Japanese whaling fleet is reportedly heading into the seas around Antarctica, drawing widespread condemnation from campaigners. Japan’s fleet of six ships left the port of Shimonoseki, western Japan with a quota of 940 minke whales and 10 fin whales. Calls for the Australian government to intervene have been rejected by the environment minister, Senator Ian Campbell. Japan’s whaling program, […]

As the planet faces the dawn of a sixth mass extinction, scientists are searching for clues about the uncertain road ahead by exploring how an ancient ecosystem collapsed and bounced back from traumatic upheavals. A new study follows the lengthy collapses and revival of South African ecosystems during one of the “big five” mass extinctions, the Permian-Triassic event, revealing unexpected […]

When spring arrives in the Arctic, both snow and sea ice melt, forming melt ponds on the surface of the sea ice. Every year, as global warming increases, melting sea ice leads to more and larger melt ponds. Melt ponds provide more light and heat for the ice and the underlying water, but now it turns out that they may […]

1. The first confirmed sighting of the continent was in 1820. 2. Explorers first reached the South Pole in 1911. 3. Because Antarctica lies in the southern hemisphere, seasons there are the opposite of seasons in the north — summer runs from October to February and winter covers the remainder of the year. 4. Antarctica is the coldest continent; temperatures […]

For the first time, a mission designed to set its eyes on black holes and other objects far from our solar system has turned its gaze back closer to home, capturing images of our sun. NASA’s Nuclear Spectroscopic Telescope Array, or NuSTAR, has taken its first picture of the sun, producing the most sensitive solar portrait ever taken in high-energy […]
