My sources are the journals Science and Nature. I follow this rather closely, since I am a Geophysicist and work in the oil industry. Really, only Exxon and members of the administration do not believe global warming is taking place. Even oil companies such as Shell and BP agree that global warming is a reality, and are trying to reduce carbon emissions accordingly. I used to work at the National Center for Atmospheric Research in Boulder, and have followed this stuff quite closely for 25 years.

In this article they note that the cooling is a temporally and spatially localized anomaly.

Mass Balance of Polar Ice Sheets Eric Rignot,1 Robert H. Thomas2 Recent advances in the determination of the mass balance of polar ice sheets show that the Greenland Ice Sheet is losing mass by near-coastal thinning, and that the West Antarctic Ice Sheet, with thickening in the west and thinning in the north, is probably thinning overall. The mass imbalance of the East Antarctic Ice Sheet is likely to be small, but even its sign cannot yet be determined. Large sectors of ice in southeast Greenland, the Amundsen Sea Embayment of West Antarctica, and the Antarctic Peninsula are changing quite rapidly as a result of processes not yet understood. 1 Jet Propulsion Laboratory, California Institute of Technology, Mail Stop 300-235, Pasadena, CA 91109, USA. 2 EG&G Services, Wallops Flight Facility, Building N-159, Wallops Island, VA 23337, USA.

"Surface thermometer measurements indicate that the temperature of the earth is wrming..." ----- Interpreting Differential Temperature Trends at the Surface and in the Lower Troposphere B. D. Santer, 1* T. M. L. Wigley, 2 D. J. Gaffen, 3 L. Bengtsson, 4 C. Doutriaux, 1 J. S. Boyle, 1 M. Esch, 4 J. J. Hnilo, 1 P. D. Jones, 5 G. A. Meehl, 2 E. Roeckner, 4 K. E. Taylor, 1 M. F. Wehner 1 Estimated global-scale temperature trends at Earth's surface (as recorded by thermometers) and in the lower troposphere (as monitored by satellites) diverge by up to 0.14°C per decade over the period 1979 to 1998. Accounting for differences in the spatial coverage of satellite and surface measurements reduces this differential, but still leaves a statistically significant residual of roughly 0.1°C per decade. Natural internal climate variability alone, as simulated in three state-of-the-art coupled atmosphere-ocean models, cannot completely explain this residual trend difference. A model forced by a combination of anthropogenic factors and volcanic aerosols yields surface-troposphere temperature trend differences closest to those observed. 1 Program for Climate Model Diagnosis and Intercomparison, Lawrence Livermore National Laboratory, Livermore, CA 94550, USA. 2 National Center for Atmospheric Research, Boulder, CO 80307, USA. 3 NOAA Air Resources Laboratory, Silver Spring, MD 20910, USA. 4 Max Planck Institute for Meteorology, D-20146 Hamburg, Germany. 5 Climatic Research Unit, University of East Anglia, Norwich NR4 7TJ, UK. Since 1979, polar-orbiting satellites have monitored atmospheric temperatures on a global scale. Satellite temperature measurements are mass-weighted averages of the microwave emissions from deep atmospheric layers (5). They are not the same physical quantity as the near-surface temperatures monitored by thermometers (6). We show that the observed difference between surface and tropospheric temperature changes cannot be fully explained by coverage differences between satellite- and surface-based measurement systems and/or the effects of natural internal climate variability. However, we find that both effects may make substantial contributions to the observed trend difference. We also discuss a recent model result that suggests that the observed warming of the surface relative to the lower troposphere may be a response to combined forcing by well-mixed greenhouse gases, sulfate aerosols, stratospheric ozone, and the effects of the Pinatubo eruption in June 1991 (12). ----- Science Volume 295, Number 5553, Issue of 11 Jan 2002, p. 275. Global Warming Continues The second warmest global surface temperature in more than a century of instrumental data (1) was recorded in the 2001 meteorological year (December 2000 through November 2001) (see panel A). The calendar year 2001 will also be the second warmest year on record, as the 11-month temperature anomaly exceeds that in the next warmest years (1990 and 1995) by almost 0.1°C. For our analysis, we used recently documented procedures for data over land (1) and for sea surface temperatures (2). The global warmth in 2001 is particularly meaningful because it occurs at a phase of the Southern Oscillation in which the tropical Pacific Ocean is cool (see panel B). The record warmth of 1998, in contrast, was bolstered by a strong El Niño that raised global temperature 0.2°C above the trend line (see panel A). Global surface air warming over the past 25 years is ~0.5°C, and in the past century is ~0.75°C (1). The recent surface warming contrasts with warming of only ~0.1°C in the troposphere over the past 22 years (3); however, surface and tropospheric warmings are similar over the past 50 years (4). The greatest warm anomalies in 2001 were in Alaska-Canada, in a band from North Africa to Central Asia, and in the Antarctic peninsula (Palmer Land). The Indian and Western Pacific oceans were unusually warm, continuing a trend of recent decades (1). The North Atlantic Ocean is notably warmer than the 1951-1980 climatology. Unusually cool conditions of recent decades, which were centered in Baffin Bay and extended south and southeast of Greenland (1), have given way to warm anomalies in the past 5 years. Overall, the 2001 temperature extends the unusual global warming of recent decades. This warming is considered to be a consequence of anthropogenic greenhouse gases (5), and thus the high 2001 temperature will likely invigorate discussions about how to slow global warming. J.
