Title: The science of climate change.

Abstract

A complex debate is underway on climate change linked to proposals for costly measures that would reshape our power grid. This confronts technical experts outside of the geophysical disciplines with extensive, but unfamiliar, data both supporting and refuting claims that serious action is warranted. For example, evidence is brought to the table from one group of astrophysicists concerned with sunspots--this group believes there is no issue man can manage; while another group of oceanographers concerned with the heat balance in the world's oceans are very alarmed at the loss of arctic ice. What is the evidence? In an effort to put some of these issues in perspective for a technical audience, without a background in geophysics, a brief survey will consider (1) an overview of the 300 years of scientific inquiry on man's relationship to climate; (2) a basic discussion of what is meant by the ''greenhouse'' and why there are concerns which include not only CO{sub 2}, but also CH{sub 4}, N{sub 2}O, and CFC's; (3) the geological record on CO{sub 2}--which likely was present at 1,000 times current levels when life began; (4) the solar luminosity and sunspot question; and (5) the current evidence for global climate change.more » We are at a juncture where we are attempting to understand the earth as an integrated dynamic system, rather than a collection of isolated components.« less
