muckamuck, First, and foremost, I do not hide behind a pseudonym. If you have the courage of your convictions reveal who you are. There is not a single pseudonym on the Declaration of Independence. As far as your comment, people or countries can commit to anything as long as there are no consequences. So, to your point, countries committed to CO2 reductions in the Paris Accord, but there is no consequence for not achieving those goals. Five years from now all the 2015 commitments will have been forgotten as they triumph in the success of the new 2022 commitments, And so it goes on - - - - !
