• Gletscher unter Isolationsdecken: Simon Norfolk’s traumatic photos capture a Swiss glacier on life support: The material, as we discern from the subsequent images, covers several square kilometers of the Rhône Glacier in Switzerland. A thermal blanket, it absorbs the sun’s heat and slows the glacial melt. The effort isn’t part of a large-scale public or governmental initiative but a matter of private enterprise. For more than a century, tourists have been able to explore the glacier from inside a human-carved ice cave there. The family that runs the attraction started laying down the thermal blanket 20 years ago to protect the glacier — and their livelihood— from vanishing.
• Indiens sechstgrößter Stadt geht das Wasser aus: Chennai water crisis: City’s reservoirs run dry: The southern Indian city of Chennai (formerly Madras) is in crisis after its four main water reservoirs ran completely dry. The acute water shortage has forced the city to scramble for urgent solutions, including drilling new boreholes. Residents have had to stand in line for hours to get water from government tanks, and restaurants have closed due to the lack of water. “Only rain can save Chennai from this situation,” an official told BBC Tamil.
• WMO verifies 3rd and 4th hottest temperature recorded on Earth, Tagesschau: In Kuwait war es mit 53,9 Grad Celsius im Jahr 2016 laut Weltwetterorganisation so heiß wie noch nie seit Beginn der offiziellen Aufzeichnungen. Auch die 53,7 Grad Celsius in Pakistan 2017 sind rekordverdächtig.
• CEO einer AI-Firma relativiert das Paper über den CO2-Ausstoß von Machine Learning-Technologie: Deep Learning and Climate Change: The example model in the paper, “Transformer with neural architecture search” is way out at the far end in terms of computational cost of what almost anyone really does in 2019. For example a more representative task, training a standard neural net inception on imagenet to 95% accuracy of recognizing object in pictures takes around 40 GPU-hours which would consume around 10 kWh and produce around 10 lbs of CO2, which is equivalent to around 2-3 hours of running a central air conditioner.
• Spy Satellite Photos Reveal Himalayan Glacier Melt Accelerating: In a new study, scientists analyzed images of 650 glaciers as the ice changed over four decades and found that, on average, the Himalayan glaciers melted twice as fast between 2000 and 2016 as they did during the previous quarter century, from 1975 to 2000.
• One Shot: Ten Years After: The photographs mark the tenth anniversary of glacier monitoring by James Balog, his associates and their project, the Extreme Ice Survey (EIS).
