- TREND ANALYSIS: TEMPERATURE
Oscillation in the Global Climate System of Period 65-70
Years," M.E. Schlesinger (Dept. Atmos. Sci., Univ. Illinois,
105 S. Gregory Ave., Urbana IL 61801), N. Ramankutty, Nature, 367(6465),
723-726, Feb. 24, 1994.
Applied singular spectrum analysis to global-mean temperature
records and identified an oscillation that has obscured
greenhouse warming in the North Atlantic and North America.
Assessment of the Role of Natural Variability in Recent Global
Impact of Snow Cover on the Heat Balance and the Rise of
Continental Spring Temperatures," P. Ya. Groisman (Natl.
Clim. Data Ctr., Federal Bldg., 37 Battery Park Ave., Asheville
NC 28801; and State Hydrol. Inst., 23 Second Line, St.
Petersburg, 199053, Russia), T.R. Karl, R.W. Knight, Science, 263(5144),
198-200, Jan. 14, 1994.
Observations show that the retreat of the extent of spring
snow cover in the Northern Hemisphere over the past 20 years
parallels a change in the influence of snow cover on the
radiative balance and observed increase of spring temperatures
over the same area. This helps explain why the 20th century
increase in surface temperature in the Northern Hemisphere has
been greatest in spring.
Computer-Based Atlas of Global Instrumental Climate Data,"
R.S. Bradley (Dept. Geol., Univ. Massachusettts, Amherst MA
01003), L.G. Ahern, F.T. Keimig, Bull. Amer. Meteor. Soc., 75(1),
35-41, Jan. 1994.
Describes color-shaded and contoured images of globally
gridded instrumental data available on Internet (as graphics
interchange format files that can be displayed on many computers)
or on CD-ROMs.
from Clim. Change, 25(2), Oct. 1993:
"Spatial and Temporal Analysis of Middle Eastern
Temperature Changes," H.A. Nasrallah (Coll. Health Sci.,
Publ. Author. Appl. Educ. & Training, Kuwait City, Kuwait),
153-161. Temperature records reveal an increase of 0.07·C per
decade from 1950-1990 that may be associated with a concurrent
increase in CO2.
"Secular Trends in High Northern Latitude Temperature
Reconstructions Based on Tree Rings," R.D. D'Arrigo
(Tree-Ring Lab., Lamont-Doherty Earth Observ., Palisades NY
10964), G.C. Jacoby, 163-177. Reconstructions for the period
1682-1968 confirm that this region is now in an abnormally warm
state compared to the past three centuries.
"Breaking Global Temperature Records After Mt.
Pinatubo," G.W. Bassett Jr. (Dept. Econ., Univ. Illinois,
POB 4348, Chicago IL 60680), Z. Lin, 179-184. The eruption has
greatly lowered the probability of a global high-temperature
record during the next few years. A lengthy comment follows (pp.
185-191) by J. Hansen (NASA-Goddard, 2880 Broadway, New York NY
10025) and H. Wilson.
of Recent Climatic Changes in the Arabian Gulf Region," H.A.
Nasrallah (Coll. Health Sci., Publ. Author. Appl. Educ. &
Training, Kuwait City, Kuwait), R.C. Balling Jr., Environ.
Conserv., 20(3), 223-226, Autumn 1993.
The observed temperature increase of 0.65·C during the past
century and accelerated warming in the past 40 years are
consistent with model predictions.
of Daily Maximum and Minimum Temperature in Canada During the
Past Century," W.R. Skinner (Atmos. Environ. Serv., 4905
Dufferin St., Downsview ON M3H 5T4, Can.), D.W. Gullett, Clim.
Bull., 27(2), 63-77, Aug. 1993.
Mean annual temperatures increased 1.1·C, with increases in
both daytime maximum and nighttime minimum temperatures. Mean
temperature range decreased in most regions.
Statistics: Time Series Analysis," R.S.J. Tol (Inst.
Environ. Stud., Vrije Univ., Amsterdam, Neth.), A.F. de Vos, Theor.
Appl. Clim., 48(2-3), 63-74, 1993.
Reports on a number of statistical investigations and
manipulations, concluding that the increase in atmospheric CO2 is
at least partly responsible for the recent increase in global
