Evidence of ancient El Niños found
"The full sediment record indicates that 15,000 years ago severe El Niño-like storms occurred at least about every 15 years, and that they have since occurred with progressively increasing frequency. Over the past 5,000 years, storms from El Niño-like climate fluctuations have occurred about every two to eight and one-half years, possibly due to enhanced trade winds," said the study's lead author, Donald T. Rodbell of Union College, in Schenectady, N.Y.El Niño Secrets in Old Egypt
Early Nile Records Valuable to Scientists
by Randolph E. Schmid
Researchers Elfatih A.B. Eltahir and Guiling Wang looked at Nile flood records dating back to A.D. 650 to develop an estimate of past El Niños. They have discovered a period, just over 1,000 years ago, that had relatively frequent El Niños, similar to the pattern of the past 20 year. When an El Niño is under way, rain is reduced over the sources of the Nile. Studies have found that about 30 percent of the change in water flow on the Nile at Aswan can be attributed to El Niño. The paper shows frequent El Niños between about 750 and 1000 with a reduction after that, and then an increase again in the latter years of this century.Evolution in Your Face
by Patrick Huyghe
Lake Victoria, Africa's largest lake, is home to more than 300 species of cichlids. These fish, which are popular in aquariums, are deep-bodied and have one nostril, rather than the usual two, on each side of the head. Seismic profiles and cores of the lake taken by a team headed by Thomas C. Johnson of the University of Minnesota, reveal that the lake dried up completely about 12,400 years ago. This means that the rate of speciation of cichlid fishes has been extremely rapid: something on average of one new species every 40 years!
and, from the topmost following title, pp 208-216:
"On June 23, 1988, climatologist James Hansen testified before a hearing of the Senate Energy and Natural Resources Committee on a day when the temperature in Washington D.C. reached a sweltering 38C... Hansen had impressive data from 2,000 weather stations... which documented not only a century-long warming trend but a sharp resumption of warming after the early 1970s... Hansen flatly proclaimed that the earth was warming on a permanent basis because of humanity's promiscuous use of fossil fuels [sic]... Recently, James Hansen and a group of his colleagues have argued that the rapid warming of recent decades has in fact been driven by non-CO2 gases such as chlorofluorocarbons. Fossil fuel [sic] burning CO2 and aerosols have both positive and negative climatic forcing effects, which tend to cancel each other out. Hansen and his team point out that the growth rate of non-CO2 gases has declined over the past decade and could be reduced even further. This, combined with a slowing of black carbon and CO2 emissions, could lead to a decline in the rate of global warming. Much more research is needed to confirm this hypothesis."
In other words, in 1988 Hansen warned Congress that CO2 would raise world temperatures. About ten years went by, after which Hansen claimed that CO2 doesn't have any net impact at all. So much for his data. Mind you, this came from the book shown below, which is egregiously in advocacy of the notion of "global warming".
