Sobering U.N. Report on Climate Change

A couple of days ago, the UN's Intergovernmental Panel on Climate Change, representing 91 top climate change researchers from 40 countries, released their long-awaited report on global climate change and the possibilities for topping rising temperatures at 1.5 degrees Celsius above preindustrial levels.   This was a report that some vulnerable nations had requested after a larger UN meeeting in Paris in 2015 had resulted in the 2016 Paris Agreement committing participating nations to put best efforts to hold global temperature rise in this century to no more than 2 degrees Celsius above preindustrial levels.  Those nations were concerned about the consequences of even a 1.5 degrees Celsius increase.  

Here's a good summary of and response to the Panel's findings, which  indicate that the consequences of a 1.5 degree increase are still quite severe, and that they may come as soon as 2040.  Click the following link for the Panel's headline findings:  Download UN panel headline findings

One of the Panel's key suggestions for staving off such a global temperature increase turns on a tax on carbon dioxide emissions.   This is a policy recommendations developed by climate economist William Nordhaus.  Probably not coincidentally, the day after the climate report was released, Nordhaus was awarded half of the Nobel Prize in Economics.
