The 2-day, science intensive Climate and Energy Conference sponsored by CFACT and EIKE stands in wonderful contrast to the glib, quick hit side events that surround the Bonn UN conference.
Expelling the U.S. delegation would be unbelievably disruptive. These are supposed to be delicate diplomatic affairs. There is no provision in the Paris Agreement for this kind of terminal action, or in the underlying UN Framework Convention on Climate Change, which is a duly ratified U.S. treaty. Fun facts: The U.S. pays 22% of the UN budget and 20% of the UN climate process.
