The Harvard Gazette: A red oak live tweets climate change

The Harvard Gazette: A red oak live tweets climate change. “Would it plead for rain in a drought? Fawn over a neighbor’s foliage? Crack jokes about how fast another tree loses its leaves in fall? It seems unlikely anyone will ever come across a loquacious linden. But for the arbor-curious, a red oak at the Harvard Forest in Petersham has been tweeting as @awitnesstree since July 17. Outfitted with sensors and cameras, and programmed with code that allows it to string together posts with prewritten bits of text, the Harvard Forest Witness Tree has been sharing on-the-ground insights into its own environmental life and that of its forest.”

University of Washington: More than 100 years of Arctic sea ice volume reconstructed with help from historic ships’ logbooks

University of Washington: More than 100 years of Arctic sea ice volume reconstructed with help from historic ships’ logbooks. “Our knowledge of the dwindling sea ice coverage in the Arctic Ocean comes mostly through satellites, which since 1979 have imaged the sea ice from above. The University of Washington’s Pan-Arctic Ice Ocean and Modeling System, or PIOMAS, is a leading tool for gauging the thickness of that ice. Until now that system has gone back only as far as 1979. A new paper now extends the estimate of Arctic sea ice volume back more than a century, to 1901. To do so it used both modern-day computer simulations and historic observations, some written by hand in the early 1900s aboard precursors to today’s U.S. Coast Guard ships.

BBC: TikTok videos spread climate change awareness

BBC: TikTok videos spread climate change awareness. “Users of the social video app TikTok have been spreading a message of climate change awareness through make-up and time-lapse videos. Their chosen hashtag of #Globalwarning – a play on the term ‘global warming’ – has been viewed more than 24 million times on the app so far.”

St. Louis Public Radio: A New Tool Can Help Mississippi River Cities Plan For Future Floods

St. Louis Public Radio: A New Tool Can Help Mississippi River Cities Plan For Future Floods. “The Mississippi River Cities and Towns Initiative (MRCTI) and the U.S. Department of the Interior created an electronic portal in response to this year’s near-record flooding. The MRCTI Imagery and Information Viewer aggregates maps, weather forecasts and up-to-date data on floods and droughts — all information necessary for cities to better plan for natural disasters.” The tool contains historical water level data as well.

Rising temperatures could increase suicides, use of depressive language on social media: Study (India Today)

India Today: Rising temperatures could increase suicides, use of depressive language on social media: Study. “Hotter weather increases both suicide rates and the use of depressive language on social media, says a new study that analysed half a billion tweets. The research published in the journal Nature Climate Change suggests that the effects of climate change could be as devastating as the influence of economic recessions when it comes to increasing suicide rates.”

Digital Trends: A.I. cameras could help stomp out wildfires before they become disastrous

Digital Trends: A.I. cameras could help stomp out wildfires before they become disastrous. “This summer marks one year since California’s deadliest and most destructive wildfire season ever. And while not for a second diminishing the devastation caused by that disaster, it’s not an isolated event. Many countries around the world are experiencing unprecedented heat waves, which pose similar fire risks. Could cutting-edge technology help?”
