1. FINANCIAL CONSTRAINTS FORCE A REEXAMINATION OF SSC PHYSICS!
A "blue-ribbon" panel of physicists has been convened on very short notice to advise DOE on the "range of useful machine parameters" of the super collider. Specifically, they were asked: "Are there some lower bounds of the technical parameters below which the physics research would be scientifically unimportant, marginally productive, or duplicative of ongoing or proposed work elsewhere? How much physics potential would be lost by reducing the machine energy below 20 TeV? Below 17 TeV? Below 15 TeV?" The charge to the panel states that it is "imperative" that their answers be received by 12 Jan 90. Sid Drell of Stanford and SLAC, who will head the study, says the panel will be able to meet the deadline.

The sharply pointed questions and the short time horizon convey a sense of crisis. Stories have circulated for several weeks that to reliably achieve its stated goal of 20 TeV goal, the SSC would have to be redesigned--with an increase in the sticker price of about $2B. Trapped between the Deficit Reduction Act and George Bush's pledge of no new taxes, DOE has its hands full just trying to maintain funding at $5.9B. The dilemma is described in detail by Irwin Goodwin in the next issue of Physics Today. He reports that Energy Secretary Watkins told Roy Schwitters, Director of the SSC, that the collider must be completed "as advertised" for $5.9B. Holding the line on the budget means cutting back on the energy. In the background looms the ample figure of Carlo Rubia, who insists that CERN can do well enough for a lot less. Thus the reference in the panel's charge to "proposed work elsewhere."

2 . ONLY A GREENHOUSE SKEPTIC COULD ENJOY THE WEATHER THIS WINTER.
The only thing scientists seem to agree on is that concentrations of greenhouse gases in the earth's atmosphere are exponentially increasing with a doubling time of about 100 years. That sounds alarming and many scientists and most of the public are alarmed. But evidence of any warming thus far is hard to find except in computer simulations. A pamphlet issued by the George C. Marshall Institute argues that if there has been a 0.5 C temperature rise, as some researchers claim, it is within the range expected from cycles of solar activity. Critics protest that the pamphlet is political, and given the fact that the last report issued by the George C. Marshall Institute vouched for the feasibility of Star Wars, they may have a point. Political or not, many scientists agree that current models are too crude to justify major programs to reduce emissions, and the Bush Administration has taken a go-slow approach. But the calamity forecasters warn that by the time we can measure the effect it may be too late to avoid a disaster. Some Soviet scientists argue that a little warming would be good.

3. HAROLD HANSON IS RETIRING AS EXECUTIVE DIRECTOR
of the House Science, Space, and Technology Committee at the end of January. He is a former professor of physics and university administrator.
