OF GENERAL INTEREST: CLIMATE CHANGE SCIENCE
"Climate Change Scenarios: Comparisons of Paleoreconstructions with
Recent Temperature Changes," M.V. Shabalova (State Hydrol. Inst., 199053
2nd Line, 23 St. Petersburg, Russia), G.P. Können, Clim. Change,
29(4), 409-428, Apr. 1995.
Paleoclimatic reconstructions for the Mid-Holocene, Eemian, Mid-Pliocene and
Last Glacial Maximum are used to test the paleoanalog hypothesis, and to develop
a regional climate change scenario based on a linear scaling by one parameterthe
mean Northern Hemisphere temperature deviation from present. Areas where the
hypothesis works well correspond to the areas of most pronounced warming. From
the three warm epochs studied, a scenario is deduced for the spatial
distribution of temperature in a future climate, on the scale of continents.
"On the Solar Ultraviolet Spectral Irradiance During the Maunder
Minimum," J.L. Lean (Hulbert Ctr., Code 7673L, Naval Res. Lab., Washington
DC 20375), O.R. White, A. Skumanich, Global Biogeochem. Cycles, 9(2),
171-182, June 1995.
Using data from the past 15 years, estimates that during the interval of
very low solar activity known as the Maunder minimum (1645-1715), solar UV
output may have been 4% below its 1980 level. The climatic consequences of such
a change have yet to be determined, but recent work (Haigh, 1994) on modulation
of radiative climate forcing by stratospheric ozone emphasizes the need to
understand the role of UV irradiance variability as one forcing mechanism.
"Lidar-Measured Winds from Space: A Key Component for Weather and
Climate Prediction," W.E. Baker (Natl. Ctr. for Environ. Prediction, 5200
Auth Rd., Camp Springs MD 20746), G.D. Emmitt et al., Bull. Amer. Meteor.
Soc., 76(6), 869-888, June 1995.
Reviews the concepts of wind measurement by Doppler lidar, highlights the
results of observing system simulations with lidar winds, and discusses
important advances in weather and climate prediction anticipated with lidar
"Global Coupled General Circulation Models," G.A. Meehl (NCAR,
POB 3000, Boulder CO 80307), Bull. Amer. Meteor. Soc., ibid.,
Presents major conclusions and recommendations on the status of coupled GCMs
from a workshop convened by the World Climate Research Program (Oct. 1994, La
Jolla, Calif.). Participants concluded that improved communication among those
engaged in this activity will be important to further progress.
