Given that the United States and most other developed anions have for over twenty - five years failed to adequately respond to climate change because of
alleged unacceptable costs to each nation and that due to the
delay ghg emissions reductions now needed to avoid potentially catastrophic climate change are much steeper and costly than what would be required if these nations acted twenty five years ago, is it just for the United States and other developed nations to now defend further inaction on climate change on the basis of cost to it?
