What if we scattered glass powder to save the ice pack?<br />This idea was developed by Arctic Ice Project, a California-based non-profit organization.<br />This method would reflect the sun's rays and thus reject heat.<br />Thus, the ice could be reconstituted.<br />Finally, this technique would fight against the rise of the sea level. <br />This technique was first tested on lakes in Canada and the United States. <br />The results are quite encouraging.<br />If the initiators of this idea specified that it was about spreading a thin layer of glass microspheres, it would take about 50 million tons of this material to cover the 4 million km2 of the ice pack.<br />But some scientists question the reliability of this method. <br />In particular, this could have negative effects on the food chain of ecosystems..<br />Living species could thus ingest this material. <br />For the last fifty years, the extent of the Arctic ice has been shrinking. <br />The Arctic is a region that is warming twice as fast as the rest of the world. <br />It had its worst year after 2012 in 2020: During the summer, with the heat waves, the thermometer showed 20°c above the seasonal norm. <br />From now on, the ice is reconstituted but it becomes thinner and less robust.
