A detailed description of the
climate change disinformation campaign that is responsible for much of the political opposition that has been largely responsible for the over 25 - year US delay in
responding to the scientific warnings about the threat of
climate change is beyond the scope of this article but has been extensively discussed on this
website under the category of «disinformation campaign.»
Dr. Ralph J. Cicerone, President of NAS, explained on the Royal Society's
website that the NAS and RS are two of the world's leading scientific bodies, and, therefore, had «a responsibility
to evaluate and explain what is known about
climate change, at least the physical side of it,
to concerned citizens, educators, decision makers and leaders, and
to advance public dialogue about how
to respond to the threats of
climate change.»
