NEW SCIENCE FROM THE ARCTIC: WE MAY HAVE ALREADY PASSED THE BIG - TopicsExpress



          

NEW SCIENCE FROM THE ARCTIC: WE MAY HAVE ALREADY PASSED THE BIG MELTING POINT In the last year, scientists discovered a climate record going back over 3 million years - long beyond the ice core records of 800,000 years. Research led by Professor Julie Brigham-Grette, from the University of Masschusetts, Amherst drastically changes our understanding of the world. Julie Brigham-Grette Shes been studying a meteor-impact lake called El gygytgyn on the Eastern tip of Siberia.Drilling into a lake in the Russian Arctic, created from a meteor strike ages ago, she found several periods where the Arctic was up to 8 degrees warmer than today. That despite carbon dioxide levels thought to be similar to, or below, todays 400 parts per million. Zoom out on this Google Map to see where that lake is. The Greenland Ice sheets have repeatedly shrunk to half current size. The West Antarctic Ice Sheet completely disappeared 1.1 million years ago. The sea level was tens of meters higher than today. All this happened not with carbon levels like the 600 parts per million and above projected by politicians and planners, but at only 400 parts per million, our current level. It appears we may have already arrived at greenhouse gas levels sufficient to drastically warm the poles, make sea ice history, melt Greenland and parts of Antarctica, and flood coastal areas around the world. All that may be only a matter of time. In the radio show I play a selection of key clips recorded from a You tube video presentation by Dr. Julie Brigham-Grette, at Amherst, in the summer of 2012 - almost a year ago, and yet hardly anyone has heard of these startling findings. Find out more at frontierscientists, hosted by University of Alaska, Fairbanks. I highly recommend you watch this full Youtube video of Julie Brigham-Grette with all the graphs and charts. Scary stuff. Source for the above is from Radio Eco Shock - Program entitled: Who Will Control the Climate of the World? ecoshock.info/2013/05/who-will-control-climate-of-world.html
