NASA has published a time lapse video that recounts the history of Ice Age glaciers starting from 122,000 years ago. The animation is based on a new model of glacier movements and the response of the Earth’s land masses. The animation was created by scientists at the University of Toronto and NASA’s Jet Propulsion Laboratory.
According to an accompanying article, the model is helping scientists understand postglacial rebound, also known as glacial isostatic adjustment, which refers to the way land masses rebound when heavy glaciers melt and disappear from the surface. This factor is crucial in predicting the rise of sea level over time.
From INFONA: “Snow bacterial abundance and diversity at the Guoqu Glacier and the East Rongbuk Glacier located in the central and southern Tibetan Plateau were investigated using a 16S rRNA gene clone library and flow cytometry approach. Bacterial abundance was observed to show seasonal variation, with different patterns, at the two glaciers. High bacterial abundance occurs during the monsoon season at the East Rongbuk Glacier and during the non-monsoon season at the Guoqu Glacier. Seasonal variation in abundance is caused by the snow bacterial growth at the East Rongbuk Glacier, but by bacterial input from the dust at the Guoqu Glacier. Under the influence of various atmospheric circulations and temperature, bacterial diversity varies seasonally at different degrees.”
From AboutVideo: “Some celebrities do not grow old, not only outwardly but also in the creative plan. In November 2016, the British singer Sting has pleased his fans with a new studio album ’57th & 9th,’ his 12th. On sounding, the album refers to the days Sting was part of the band The Police. The success of the new album has fixed the singer in the top twenty of the UK Albums Charts… In the song ‘One Fine Day,’ Sting sings about protecting the environment. He calls for common sense with regard to nature and its gifts. The musician appears in the video as a silhouette on crumpled paper. The beautiful images on paper give a sense of danger. Sting shows how the glaciers are melting and the politicians are endlessly arguing with each other, leading to the destruction of the planet.”
From Pamir Times: “A group of mountaineers and a researcher from Shimshal Valley – Hunza, reached Askoli, a remote mountain village in Skardu, after walking across the Braldu Pass. They are on a a mission to raise awareness about saving glaciers from depleting… The expedition members surveyed Mulungdi glacier and Khurdupin glacier before embarking on their journey to Askoli on January 6… Pakistan is home to world’s largest ice glaciers out of the polar region. Spread over an area of 16933 square kilometers, there are over 5000 glaciers in the Gilgit-Baltistan and Chitral regions of Pakistan, including the famous Siachin Glacier, Biafo Glacier, Khoordhopin Glacier, Batura Glacier, Braldu Glacier, Snow lake and many more. These glaciers are the major source of water feeding the major rivers in Pakistan.”
