Purdue University: Turn off that camera during virtual meetings, environmental study says

Purdue University: Turn off that camera during virtual meetings, environmental study says. “Just one hour of videoconferencing or streaming, for example, emits 150-1,000 grams of carbon dioxide (a gallon of gasoline burned from a car emits about 8,887 grams), requires 2-12 liters of water and demands a land area adding up to about the size of an iPad Mini. But leaving your camera off during a web call can reduce these footprints by 96%. Streaming content in standard definition rather than in high definition while using apps such as Netflix or Hulu also could bring an 86% reduction, the researchers estimated.”

MIT News: Shrinking deep learning’s carbon footprint

MIT News: Shrinking deep learning’s carbon footprint. “Some of the excitement over AI’s recent progress has shifted to alarm. In a study last year, researchers at the University of Massachusetts at Amherst estimated that training a large deep-learning model produces 626,000 pounds of planet-warming carbon dioxide, equal to the lifetime emissions of five cars. As models grow bigger, their demand for computing is outpacing improvements in hardware efficiency. Chips specialized for neural-network processing, like GPUs (graphics processing units) and TPUs (tensor processing units), have offset the demand for more computing, but not by enough.”

Paul Scherrer Institute: Life cycle assessment of cars – new web tool helps consumers and researchers

Paul Scherrer Institute: Life cycle assessment of cars – new web tool helps consumers and researchers. “Researchers at the Paul Scherrer Institute have developed a web tool called the Carculator that can be used to compare the environmental performance of passenger cars in detail. The program determines the environmental balance of vehicles with different size classes and powertrains, and presents the results in comparative graphics. The entire life cycle of the passenger cars is taken into account, including the manufacture of the vehicles and the environmentally relevant emissions from driving.”

Penn State News: Libraries virtual exhibition highlights human impact on our planet

Penn State News: Libraries virtual exhibition highlights human impact on our planet. “The virtual exhibition invites the viewer to consider a range of environmental-related topics and will serve as a growing, centralized resource for the Libraries’ rich trove of primary sources focused around key issues and themes: Climate Change and Weather Data, Energy and Extraction History, Environmental Disasters and Pollution, Arctic Exploration, Eco-Materiality and Future Speculations, Biodiversity, and Environmental Protection and Activism.”

Department of Environmental Conservation, New York: DEC Launches New ‘DECinfo Locator’ to Increase Transparency and Access to Data and Reports

Department of Environmental Conservation, New York: DEC Launches New ‘DECinfo Locator’ to Increase Transparency and Access to Data and Reports. “With more than 50 interactive data layers, DECinfo Locator lets users see and download permits, former industrial site cleanup plans, water quality reports, and more based on where they live, work, or play. Selecting a map feature can bring up links to database records for petroleum bulk storage facilities, oil wells, or permitted mines…. The map’s Near Me feature lets users narrow data results by creating an interactive list of data points within an area of up to 10 miles from a selected point. In addition to environmental quality information, users can explore new places for recreation such as hiking, cross-country skiing, or mountain biking, or look up the rules for a nearby Wildlife Management Area.”

National Geographic: Do We Know Enough About The Deep Sea To Mine It?

National Geographic: Do We Know Enough About The Deep Sea To Mine It?. “The United Nations organisation [International Seabed Authority (ISA)] headquartered in Kingston, Jamaica, is charged with promoting the mining of the ocean floor while, contradictorily, ensuring its protection. That’s about to change. As the ISA meets this month to draft regulations to allow mining to begin, it is set to unveil a public database that contains all environmental data reported by the miners since 2001. For the first time, scientists will be able to analyse the quantity and quality of that information and determine if mining contractors have complied with ISA rules.”

Florida Museum: New Data Platform Illuminates History Of Humans’ Environmental Impact

Florida Museum: New Data Platform Illuminates History Of Humans’ Environmental Impact. “The human environmental footprint is not only deep, but old. Ancient traces of this footprint can be found in animal bones, shells, scales and antlers at archaeological sites. Together, these specimens tell the millennia-long story of how humans have hunted, domesticated and transported animals, altered landscapes and responded to environmental changes such as shifting temperatures and sea levels. Now, that story is available digitally through a new open-access data platform known as ZooArchNet, which links records of animals across biological and archaeological databases.”
