The current mass extinction http://arctic-news.blogspot.com/
The definitive measure of Anthropocene global warming, i.e. the rise in the atmospheric concentration of CO₂, to date by 49 percent since pre-industrial time (from 280 ppm to currently 419 ppm), is only rarely mentioned by the media or politicians. Nor are the levels of methane and nitrous oxide, which have risen by about 3-fold. To date potential attempts toward climate mitigation and adaptation have failed. There is a heavy price in communicating distressing projections, Cassandra-like, where climate scientists have been threatened, penalized or dismissed, including from major institutions. In this video, Guy McPherson discusses the current mass extinction. https://www.youtube.com/watch?v=_VcuEZR_1MM&feature=emb_imp_woyt Barry -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
