According to the National Academy of Sciences (NAS) report (a letter, not a full assessment), \u201cIn view of the uncertainties, controversies, and complex linkages surrounding the carbon dioxide issue, and the possibility that some of the greatest uncertainties will be reduced within the decade, it seems to most of us that the near-term emphasis should be on research, with as low a political profile as possible [emphasis in original document]\u2026We do not know enough to address most of these questions right now. We believe that we can learn faster than the problem can develop.\u201d* John Perry, a meteorologist and chief staff officer for the Academy\u2019s Climate Research Board, criticized this assessment in a guest editorial in the Journal Climatic Change entitled \u201cEnergy and Climate: Today\u2019s Problem, not Tomorrow\u2019s\u201d by arguing, \u201cIf we have good reason to believe that a 100 percent increase in carbon dioxide will produce significant impacts on climate, then we must have equally good reason to suspect that even the small increase we have already produced may have subtly altered our climate\u2026. Climate change is not a matter for the next century; we are most probably doing it right now.\u201d**<\/p>\n<p class=\"footnote-body\">*Naomi Oreskes and Erik M.
