Marine CO2 Uptake: Heated discussion of the importance of oceanic
biological production to the anthropogenic rise in atmospheric CO2 continues in
Global Biogeochem. Cycles. Recent papers by Broecker (GLOBAL CLIMATE
CHANGE DIGEST, Prof. Pubs./Of Gen. Interest, Dec. 1991) and by Smith and
Mackenzie minimize the importance, while others vehemently disagree (see Prof.
Pubs./Marine CO2 Uptake, this issue--Jan. 1992). Smith and Mackenzie also
comment on the views of R. Revelle on this topic in Issues Sci. Technol.,
p. 26, Fall 1991. See also Karl and Winn paper on JGOFS in Prof. Pubs./Gen.
Interest, and a letter by Broecker on WOCE and JGOFS, Science, p. 1566,
Dec. 13, 1991.
Results of a five-year study of CO2 concentrations in the South Pacific,
presented at the December American Geophysical Union meeting and in a paper by
Murphy et al. (see Prof. Pubs./Marine CO2 Uptake) call into question the ocean's
accepted role in absorbing CO2.
The Effects of Particles and Clouds on climate is the topic of a
press release from an IAMAP symposium at the 20th IUGG General Assembly (Vienna,
Aug. 1991), published in Atmos. Environ., 26(3), p. 522, 1992.
It concludes that in the absence of better data, the degree to which
anthropogenic particles and cloud augmentation offset greenhouse warming remains
a matter of speculation.
