The temperature-driven change in the mobility of water molecules on the surface perfectly matches how ice’s friction coefficient changes with temperature — the more mobility at the surface, the lower the friction. - https://www.zmescience.com/science/ice-slippery-h-bonds-8731058/ “As the physicist Richard Feynman predicted, the solution was not to be found in new equations, but rather within the equation that was already available to us,” explained Tobias Schneider, author of the new study. “Until now, researchers didn’t have powerful enough mathematical tools to verify this.”- https://www.zmescience.com[..]ws-science/turbulent-fluid-flow-28052019 Even in desert air, a single kilogram of this cheap gel was able to capture more than 6 liters of water per day. - https://www.zmescience.com[..]rinking-water-literally-out-of-thin-air/ Mind The Water Gap, Mapping the world’s water shortages - https://worldwatermap.nationalgeographic.org/ Is water wet?

愛斯基摩人成為全球暖化首批氣候難民 地球暖化日益嚴重，全球民眾受害，而住在北極圈附近的愛斯基摩人更是首當其衝，因為他們居住的極地小島日漸縮小，有可能遭海水淹沒，因此迫使他們遷移，這使得愛斯基摩人成為全球第一批氣候難民。根據紀錄，美國阿拉斯加地區的氣溫過去30年上升了攝氏4度，導致冰河溶化，海水上升，當地一座小島「沙里契夫」的面積已經減半，北極圈內許多愛斯基摩村莊都面臨不保威脅。當地一名愛斯基摩人說，全球暖化使得他們週遭的風浪一年比一年大，土地流失一年比一年嚴重，漁獲量也不如從前，不少村民已經陸續遷移，但仍有不少人因為經濟無力負擔，留在原地，前途未卜。 ref: http://tw.news.yahoo.com/article/url/d/a/070305/1/b5eu.html What is the albedo effect, and why it matters in the climate crisis - https://www.zmescience.com[..]feature-post/the-albedo-effect-05032021/ Coffee waste can help restore degraded land and forests - https://www.zmescience.com[..]-help-restore-degraded-land-and-forests/ How much of our emissions come from agriculture? - https://www.zmescience.com[..]-of-our-emissions-come-from-agriculture/ The rivers that 'breathe' greenhouse gases - https://www.bbc.com[..]the-rivers-that-breathe-greenhouse-gases Biochar can help us keep climate change at bay and more food on the table, according to a new meta-study - https://www.zmescience.com[..]ochar-agriculture-climate-change-246423/ Future Planet - https://www.bbc.com/future/future-planet E airplane - https://www.nationalgeographic.com[..]-we-make-air-travel-and-how-soon-feature https://www.nationalgeographic.com[..]/take-a-look-inside-the-flying-v-feature Heat waves: How France has cut death toll 90% since 2003 - https://www.csmonitor.com[..]-France-has-cut-death-toll-90-since-2003 Restor is a science-based open data platform to support and connect the global restoration movement - https://restor.eco/ bogs - https://www.nationalgeographic.com[..]a-del-fuego-photos-reveal-beauty-of-bogs 4 solutions for trees and forests threatened by a hotter world - https://www.nationalgeographic.com[..]ons-fixing-forests-fight-warming-feature Peatlands help protect us from climate change.
