Science of Global Warming Hot Times Or Hot Air: The Sun in the
Science of Global Warming August 07, 1998 The global warming
scare assumes that human emissions of carbon dioxide and other
greenhouse gases are the dominant driving force in recent and
probable future climate changes. Yet as Dr. Sallie Baliunas
points out in the lecture published below, surface temperature
records indicate that the world has warmed only about 0.5
degrees centigrade during the last 100 years roughly half the
amount "predicted" by the computer models on which warming
scenarios are based. Moreover, at least half the warming
observed during the 20th century occurred before 1940, while
most of the increase in greenhouse gas concentrations occurred
after 1940. That suggests that of the observed warming, mankind
is responsible for only one or two tenths of a degree. It
further suggests that any future temperature increases due to
industrial activity during the next century a
