DELAY EMISSION CUTS?
A paper in the January 18, 1996, issue of Nature
promotes the advantages of delaying major cuts in greenhouse gas emissions by
perhaps 30 years, suggesting that the long-term result will be little different
than cutting emissions now, but the overall cost will be much less. (See Prof.
Pubs./Of Gen. Interest, this Digest issue--Mar. 1996.) What will
surprise many advocates of climate action more than the content of the proposal
is the identity of the lead author. Climatologist Tom Wigley of the University
Corporation for Atmospheric Research is a leading advocate of greenhouse gas
emission controls, and a contributor the recent IPCC assessment. In a New
Scientist article on the paper (p. 7, Jan. 20), Wigley insists he has not
deviated from his previous views, but has merely added a dose of economic and
political realism to the IPPC's work. New Scientist also discusses the
views of two other major players who dispute the paper's conclusion: economist
Michael Grubb of the Royal Institute of International Affairs, and John
Houghton, chair of the IPCC science working group.
