Challenge to Scientific Consensus on Global Warming: Analysis Finds Hundreds of Scientists Have Published Evidence Countering Man-Made Global Warming Fears

    WASHINGTON, Sept. 12 /PRNewswire-USNewswire/ -- A new analysis of
 peer-reviewed literature reveals that more than 500 scientists have
 published evidence refuting at least one element of current man-made global
 warming scares. More than 300 of the scientists found evidence that 1) a
 natural moderate 1,500-year climate cycle has produced more than a dozen
 global warmings similar to ours since the last Ice Age and/or that 2) our
 Modern Warming is linked strongly to variations in the sun's irradiance.
 "This data and the list of scientists make a mockery of recent claims that
 a scientific consensus blames humans as the primary cause of global
 temperature increases since 1850," said Hudson Institute Senior Fellow
 Dennis Avery.
     Other researchers found evidence that 3) sea levels are failing to rise
 importantly; 4) that our storms and droughts are becoming fewer and milder
 with this warming as they did during previous global warmings; 5) that
 human deaths will be reduced with warming because cold kills twice as many
 people as heat; and 6) that corals, trees, birds, mammals, and butterflies
 are adapting well to the routine reality of changing climate.
     Despite being published in such journals such as Science, Nature and
 Geophysical Review Letters, these scientists have gotten little media
 attention. "Not all of these researchers would describe themselves as
 global warming skeptics," said Avery, "but the evidence in their studies is
 there for all to see."
     The names were compiled by Avery and climate physicist S. Fred Singer,
 the co-authors of the new book Unstoppable Global Warming: Every 1,500
 Years, mainly from the peer-reviewed studies cited in their book. The
 researchers' specialties include tree rings, sea levels, stalagmites,
 lichens, pollen, plankton, insects, public health, Chinese history and
     "We've had a Greenhouse Theory with no evidence to support it-except a
 moderate warming turned into a scare by computer models whose results have
 never been verified with real-world events," said co-author Singer. "On the
 other hand, we have compelling evidence of a real-world climate cycle
 averaging 1470 years (plus or minus 500) running through the last million
 years of history. The climate cycle has above all been moderate, and the
 trees, bears, birds, and humans have quietly adapted."
     "Two thousand years of published human histories say that the warm
 periods were good for people," says Avery. "It was the harsh, unstable Dark
 Ages and Little Ice Age that brought bigger storms, untimely frost,
 widespread famine and plagues of disease." "There may have been a consensus
 of guesses among climate model-builders," says Singer. "However, the models
 only reflect the warming, not its cause." He noted that about 70 percent of
 the earth's post-1850 warming came before 1940, and thus was probably not
 caused by human-emitted greenhouse gases. The net post-1940 warming totals
 only a tiny 0.2 degrees C.
     The historic evidence of the natural cycle includes the 5000-year
 record of Nile floods, 1st-century Roman wine production in Britain, and
 thousands of museum paintings that portrayed sunnier skies during the
 Medieval Warming and more cloudiness during the Little Ice Age. The
 physical evidence comes from oxygen isotopes, beryllium ions, tiny sea and
 pollen fossils, and ancient tree rings. The evidence recovered from ice
 cores, sea and lake sediments, cave stalagmites and glaciers has been
 analyzed by electron microscopes, satellites, and computers. Temperatures
 during the Medieval Warming Period on California's Whitewing Mountain must
 have been 3.2 degrees warmer than today, says Constance Millar of the U.S.
 Forest Service, based on her study of seven species of relict trees that
 grew above today's tree line.
     Singer emphasized, "Humans have known since the invention of the
 telescope that the earth's climate variations were linked to the sunspot
 cycle, but we had not understood how. Recent experiments have demonstrated
 that more or fewer cosmic rays hitting the earth create more or fewer of
 the low, cooling clouds that deflect solar heat back into space-amplifying
 small variations in the intensity of the sun.
     Avery and Singer noted that there are hundreds of additional
 peer-reviewed studies that have found cycle evidence, and that they will
 publish additional researchers' names and studies. They also noted that
 their book was funded by Wallace O. Sellers, a Hudson board member, without
 any corporate contributions.
