2:28 PM | A ‘Bumper-Car’ Ride in the Ice Mélange
Today’s plan is to extend the sampling to include a wider region of the water exchange between Alison (Nanatakavsaup), the surrounding ocean and the connection to Hayes glacier. At the Village Meeting we had queried the local fisherman about the iceberg exit pathways for both Alison and Hayes to confirm or correct information we have gleaned from satellite imagery.

12:57 PM | World Trade Center Ship Traced to Colonial-Era Philadelphia
Four years ago this month, archeologists monitoring the excavation of the former World Trade Center site uncovered a ghostly surprise: the bones of an ancient sailing ship. In a new study, scientists at Lamont-Doherty Earth Observatory say that an old growth forest in the Philadelphia area supplied the white oak used in the ship’s frame, and that the trees were probably cut in 1773 or so—a few years before the bloody war that established America’s independence from Britain.

9:59 AM | Temperatures make our global warming opinions change like the weather
Our experience of current warmth can override our scientific knowledge in driving beliefs about climate change, which is part of the reason we struggle to take the resulting risks seriously, underlines Columbia University’s Elke Weber.

11:00 AM | Geosciences Column: The Toba eruption probably did have a global effect after all
Almost everyone has heard of the Toba super-eruption, which took place on the island of Sumatra roughly 74,000 years ago, but the only evidence of tephra or tuff (volcanic fragments) from the eruption is in Asia, with nothing definite further afield. It has sometimes been thought that this huge eruption may have led to a […]

8:53 PM | Dropped cell phone calls become rain gauges in West Africa
A shaky cell phone connection during a rainstorm can be an annoying nuisance. But now scientists are showing that these weakened signals can be used to monitor rainfall in West Africa, a technique that could help cities in the region better prepare for floods and combat weather-related diseases.

3:40 PM | The Pre-Holocene Climate Is Returning — And It Won't Be Fun
Our planet has been witness to plenty of strange weather happenings recently, from devastating floods to the polar vortex. These events are providing a glimpse of what it was like during the pre-Holocene era — a time of volatility and destruction. But it could also be a demonstration of where climate change is taking us.

5:20 PM | The Little-Known Story of El Niño And the Mutiny on the Bounty
The "Great El Niño" lasted from 1789 to 1793, profoundly impacting weather and causing massive droughts. A lesser-known consequence of this climatic event is that it saved the lives of Captain William Bligh and his crew when the mutineers on the HMS Bounty set them adrift in the South Pacific.Read more...

12:58 AM | A meeting for the Kullorsuaq Community
It seems that many of the local fishermen have gone to hunt Narwal further north but there are several good prospects for boats that Søren will scout further as several of the fishermen are sleeping as the fishing is better right now at night. With 24 hours of daylight day or night fishing doesn’t really seem to matter.

11:10 AM | CO2 emissions drive heatwaves on despite warming ‘hiatus’
Direct effects from greenhouse gases are playing a significant role in making hot Northern Hemisphere summers more common even as average temperature increases slow down, find Youichi Kamae from the National Institute for Environmental Studies in Japan and his colleagues.

5:02 PM | 10 reasons why policy makers should take direct air capture seriously
Despite the fact that the impacts of manmade climate change are already being felt and that failure to mitigate these effects by lessening fossil fuel CO2 emissions could result in dire consequences, policies enacted to reduce these emissions have been grossly insufficient. While there is no one silver bullet to “solve” climate change, many technologically [...]
