RESEARCH NEWS


Item #d90jun100

"Satellite Data under Scrutiny," D. Jones, T.M.L. Wigley, Nature, p. 711, Apr. 19, 1990. Conclusions from a study of 10 years of global temperature measurements are unfortunately being taken out of context to imply that the authors found no evidence for global warming in general. (See Spencer paper, PROF. PUBS./OF GEN. INTEREST, this Global Climate Change Digest issue--June 1990.)


Item #d90jun101

"Effects of CFC Substitutes," K. Shine, Nature, pp. 492-493, Apr. 5, 1990; "CFC Substitutes Will Still Add to Global Warming," J. Johnson, New Scientist, p. 20, Apr. 14. Du Pont scientists and colleagues have reported computer modeling estimates of the ozone-depletion and greenhouse potential of some substitutes. (See Fisher articles, PROF. PUBS./OF GEN. INTEREST, this Global Climate Change Digest issue--June 1990.)


Item #d90jun102

"Computer Model Confirms Global Warming," New Scientist, p. 31, Apr. 7, 1990. General circulation model results reported by University of East Anglia scientists strengthen the degree of consistency between the increase in carbon dioxide and global warming observed over the past 100 years. (See Wigley article, PROF. PUBS./TREND ANALYSIS AND PREDICTION, this Global Climate Change Digest issue--June 1990.)


Item #d90jun103

"Ultraviolet Levels Climb in the Swiss Alps," R. Monastersky, Science News, p. 228, Apr. 14, 1990. Austrian scientists have measured an increasing trend in UV-B radiation, in contrast to the UV-B decrease measured recently at U.S. stations. Some question the validity of the instruments used in the U.S. study. (See Blumthaler, PROF. PUBS./TREND ANALYSIS AND PREDICTION, this Global Climate Change Digest issue--June 1990.)


Item #d90jun104

"Friendlier CFC Offers Temporary Ozone Relief," J. Johnson, New Scientist, p. 28, Mar. 24, 1990. Results from a three-dimensional computer model show that CFC-123 is much less damaging to the ozone layer than CFC-11, the most common refrigerant. (See Prinn article, PROF. PUBS./GLOBAL MODELING, this Global Climate Change Digest issue--June 1990.)


Item #d90jun105

"Bad News from the Arctic with Signs of Dry Nitrogen Removal," R.L. Jones, Nature, pp. 294-295, Mar. 22, 1990. Recent observations shed light on the process by which polar stratospheric clouds remove nitrogen compounds from the stratosphere, which would otherwise neutralize reactive chlorine and slow ozone destruction. (See Fahey article, PROF. PUBS./STRATOSPHERIC OZONE CHEMISTRY, this Global Climate Change Digest issue--June 1990.)


Item #d90jun106

"Greenhouse Cooling Up High," R.J. Cicerone, Nature, pp. 104-105, Mar. 8, 1990. Recent work indicates that carbon dioxide and methane emissions could have a dramatic effect on the temperature and composition of the upper atmosphere (above the stratosphere). (See Roble article, Global Climate Change Digest, PROF. PUBS./GLOBAL MODELING, Mar. 1990.)
