Global Warming Facts…

And by facts I mean scientific studies that show, maybe the hype about global warming and climate change is a bit over done.  The end is not near, mankind is not killing the planet, the world will keep turning and climate will keep changing as it always has with or without humans.

P. Chylek, et al. 2004″Global warming and the Greenland ice sheet,” Climate Change 63, 201-21. “Since 1940… data have undergone predominantly a cooling trend…. The Greenland ice sheet and coastal regions are not following the current global warming trend.”

Doran, P. T., Priscu, J. C., Lyons, W. B., Walsh, … and Parsons, A. N., 2002, “Antarctic climate cooling and terrestrial ecosystem response,” Nature 415: 517-20.
From 1986 to 2000 central Antarctic valleys cooled .7 degrees Celsius per decade with serious ecosystem damage from cold.

Comiso, J. C., 2000, “Variability and trends in Antarctic surface temperatures from in situ and satellite infrared measurements,”Journal of Climate 13: 1674-96.
Both satellite data and ground stations show slight cooling over the last 20 years.

Joughin, I., and Tulaczyk, S., 2002, “Positive mass balance of the Ross Ice Streams, West Antarctica,” Science 295: 476-80.
Side-looking radar measurements show West Antarctic ice is increasing at 26.8 gigatons/yr. Reversing the melting trend of the last 6,000 years.

Thompson, D. W. J., and Solomon, S., 2002, “Interpretation of recent Southern Hemisphere climate change,” Science 296: 895-99.
Antarctic peninsula has warmed several degrees while interior has cooled somewhat. Ice shelves have retreated but sea ice has increased.

Petit, J. R., Jouzel, J., Raynaud, D., Barkov, N. L., … and Stievenard, M., 1999, “Climate and atmospheric history of the past 420,000 years from the Vostok ice core, Antarctica,”Nature 399: 429-36.
During the last four interglacials, going back 420,000 years, the Earth was warmer that it is today.

Anderson, J. B., and Andrews, J. T., 1999, “Radiocarbon constraints on ice sheet advance and retreat in the Weddell Sea, Antarctica,” Geology 27: 179-82.
Less Antarctic ice has melted today than occurred during the last interglacial.

Liu, J., Curry, J. A., and Martinson, D. G., 2004, “Interpretation of recent Antarctic sea ice variability,” Geophysical Research Letters 31: 10.1029/2003 GLO18732.
Antarctic sea ice has increased since 1979.

Vyas, N. K., Dash, M. K., Bhandari, S. M., Khare, N., Mitra, A., and Pandey, P. C., 2003, “On the secular trends in sea ice extent over the antarctic region based on OCEANSAT-1 MSMR observations,” International Journal of Remote Sensing, 24: 2277-87.
Trend toward more sea ice may be accelerating.

Parkinson, C. L., 2002, “Trends in the length of the souther Ocean sea-ice season, 1979-99,” Annals of Glaciology 34: 435-40.
The greater part of Antarctica experiences a longer sea-ice season, lasting 21 days longer than it did in 1979.

Climate Change 2001: The Scientific Basis. Cambridge, UK: Cambridge University Press, 2001, p. 774: “In climate research and modeling, we should recognize that we are dealing with a coupled non-linear chaotic system, and therefore that the long-term prediction of future climate states is not possible.”

Same as above. Climate Change 1995: The Science of Climate Change, p. 330. “Natural climate variability on long time-scales will continue to be problematic for CO2 climate change analysis and detection.”

C. Landsea, et al., 2000, “How much skill was there in forecasting the very strong 1997-1998 El Nino?” Bulletin of the American Meteorological Society 81: 2107-19. “… one could have even less confidence in anthropogenic global warming studies because of the lack of skill in predicting El Nino… the successes of ENSO forecasting have been overstated (sometimes drastically) and misapplied it in other arenas.”

Fred Pearce, “Africans go back to the land as plants reclaim the desert,” New Scientist 175, 21 September 20021 pp. 4-5. “Africa’s deserts are in retreat… Analysis of satellite images… reveals that dunes are retreating right across the Sahel region… Vegetation is ousting sand across a swathe of land stretching… 6,000 kilometers… Analysts say the gradual greening has been happening since the mid 1980’s, though has gone largely unnoticed.”

Paul Reiter, et al, “Global warming and malaria: a call for accuracy,” Lancet, 4, no. 1 (June 2004).”Many of these much-publicized predictions are ill informed and misleading.”

Roger J. Braithwaite, “Glacier mass balance, the first 50 years of international monitoring,” Progress in Physical Geography 26 no. 1 (2002): 76-95. “There is no obvious common global trend of increasing glacier melt in recent years.”

The fallowing quotations is from the IPCC.
According to the United Nations Intergovernmental Panel on Climate Change, “Examination of meteorological data fails to support the perception [of increased frequency and severity of extreme climate events] in the context of long term climate change.”
“Overall, there is no evidence that extreme weather events, or climate variability, has increased, in a global sense, throughout the twentieth century…”
“No long term trend events” for tropical and extratropical storms, and no systematic changes in the “frequency of tornadoes, thunder days, or hail.”

Nature 22 (October 2003):395-741, stated that, with Russia signed on, temperature affected by Kyoto would be -.02 degrees Celsius by 2050.
IPCC models estimate more but none exceed .15 degrees Celsius.

Thank you Dr. M. Crichton for compiling this list.
