In the online blog Arctic Sea Ice John Nissen, chairman of the Arctic Methane Emergency Working Group and other scientists involved in studying the Arctic Circle and it's effect on the planet's climate are making some dire predictions about the future of the planet. The predictions are about how they see climate change panning out in in the next few decades.
"So my conclusion on global warming temperature rise is between 1.5°C and 3°C by 2030, while the Arctic warms at least 5°C above current temperatures. We must not go there!" - JOHN NISSEN. Chairman of the Arctic Methane Emergency Working Group
"The bad effects forecast for end of the century (4°C warming worldwide, 10°C in Arctic) will actually occur by about 2060. The speed of change is catastrophic for agriculture; warfare and population crashes will ensue." - Professor PETER WADHAMS. Professor of Ocean Physics, Cambridge University, UK
"Most worrying is that such intense local warming in the Arctic can cause large abrupt methane releases from sediments. This would add a lot of additional warming that would result in massive crop losses globally, threatening global fresh water supply and causing extinction on a massive scale." - SAM CARANA. Blogger, http://samcarana.blogspot.ie/
"Whatever the additional warming may be [because of already unavoidable committed warming], the multiple cascading Arctic positive feedback domino effect is already unstoppable except by cooling." - PETER CARTER MD. Canada. climate-emergency-institute.org
