Three related items from Nature, 366(6435), Dec. 9, 1993:

"Two Cores Are Better Than One," G.S. Boulton (Dept. Geol., Univ. Edinburgh, Kings Bldgs., Edinburgh EH9 EJW, UK), 507-508. Discusses implications of the following two papers.

"Electrical Conductivity Measurements from the GISP2 and GRIP Greenland Ice Cores," K.C. Taylor (POB 60220, Desert Res. Inst., Univ. Nevada, Reno NV 89506), C.U. Hammer et al., 549-542.

Item #d94jan7

"A Strategy for Integrated Monitoring," B.B. Hicks (ARL, NOAA, 1325 East-West Hwy., Silver Spring MD 20910), T.G. Brydges, Environ. Mgmt., 18(1), 1-12, Jan.-Feb. 1994.

Presents an approach to integrated monitoring and analysis, based on the concept of nested networks, as a strategy for unifying measurements in different disciplines to address complex environmental concerns.

Item #d94jan8

"A Dramatic Decrease in the Growth Rate of Atmospheric Methane in the Northern Hemisphere During 1992," E.J. Dlugokencky (CMDL, NOAA, 325 Broadway, Boulder CO 80303), K.A. Masaire et al., Geophys. Res. Lett., 21(1), 45-48, Jan. 1, 1994.

Global measurements show that the average trend in 1992 was only a sixth of that for 1983-1991. A major factor may be decreased emissions from the former Soviet Union resulting from a more efficient natural gas system and reduced coal production. Measurements suggest that modest decreases in anthropogenic emissions can lead to rapid stabilization of, or a decrease in, the atmospheric methane burden.
