James Hansen Challenges the 2 Degrees Target

A new paper by James Hansen and Jeffrey Sachs was published in the Open Access journal PLOS One, arguing that a global warming target of 2 degrees Celsius is not acceptable and will lead to disastrous consequences. According to a summary at The Climate Desk, Hansen has said that the paper is intended as “a tool for the courthouse, rather than the scientific debate hall”…”We started this paper to provide a basis for legal actions against governments in not doing their jobs in protecting the rights of young people and future generations.” See: http://climatedesk.org/2013/12/scientists-current-international-warming-target-is-disastrous/.  The full article, “Assessing Dangerous Climate Change: Required Reduction of Carbon Emissions to Protect Young People, Future Generations, and Nature” is at PlosOne at:https://www.documentcloud.org/documents/876989-hansen-plos-one.html.
