Published July 1988 through June 1999
FROM VOLUME 7, NUMBER 4, APRIL 1994
- OF GENERAL INTEREST: SCIENCE
from Science, 263(5153), Mar. 18, 1994:
"Did Pinatubo Send Climate-Warming Gases into a
Dither?" R.A. Kerr, 1562. Speculates why the increase in
three greenhouse gases--carbon monoxide (next article), methane,
and nitrous oxide--sharply slowed or stopped in 1991. One
possibility is the effect of Mount Pinatubo.
"Recent Changes in Atmospheric Carbon Monoxide,"
P.C. Novelli (CIRES, Univ. Colorado, Boulder CO 80309), K.A.
Masarie et al., 1587-1590. Measurements from 27 locations between
71·N and 41·S show that levels have decreased worldwide over
the past two-to-five years, reversing a 30-year increasing trend.
The decrease is abrupt in the tropics compared to high northern
Bleaching Threatens Oceans, Life," R.S. Montgomery (U.S.
Naval Acad., Annapolis, Md.), A.E. Strong, Eos, 75(13),
145-147, Mar. 29, 1994.
Compares cases of coral bleaching with Bermuda water
temperature data. The limited studies done so far have not
revealed any evidence that gobal-scale warming of the oceans is
responsible for the cases of coral bleaching observed throughout
Influence of Climate Change and the Timing of Stratospheric
Warmings on Arctic Ozone Depletion," J. Austin (Meteor.
Office, London Rd., Bracknell RG12 2SZ, UK), N. Butchart, J.
Geophys. Res., 99(D1), 1127-1145, Jan. 20, 1994.
Uses a 3-D dynamical-radiative-photochemical model to show
that any significant risk of an Arctic ozone hole will be
confined to those years with a late stratospheric warming.
Drilling Depth Struck in Greenland," P.A. Mayewski (Inst.
Study of Earth, Ocean & Space, Univ. New Hampshire, Durham NH
03824), M. Wumkes et al., Eos, 75(10), 113, 119,
124, Mar. 8, 1994.
Last July the Greenland Ice Sheet Project (GISP2) hit bedrock,
producing the deepest ice core ever recovered (3053 meters). This
article reviews the program, and its results (including
anthropogenic influences), and future goals.
