It's not so some huge deal can be made of, e.g., 1934 now being thought to have been slightly cooler than 1999, because in and of itself that's pretty meaningless, but rather because data accuracy in turn affects the accuracy of climate model projections and in particular (in the case of this data) regional projections for the U.S. (realclimate.org)
The scenarios were also tailored to produce regional projections in areas including the U.S. Atlantic, Gulf of Mexico and Pacific coasts, Alaska, Hawaii, the Caribbean and Pacific island territories. (sciencedaily.com)
Attendees explored how regional projections are developed and their utility in short - and long - term planning for local governments. (southeastfloridaclimatecompact.org)
