This article is from Pravda, the Russian news agency. So much for the scientific consensus on global warming.
The earth is now on the brink of entering another Ice Age, according to
a
large and compelling body of evidence from within the field of climate
science. Many sources of data which provide our knowledge base of long-term
climate change indicate that the warm, twelve thousand year-long Holocene
period
will rather soon be coming to an end, and then the earth will return
to Ice Age
conditions for the next 100,000 years.
Ice cores, ocean
sediment cores, the
geologic record, and studies of ancient plant and animal
populations all
demonstrate a regular cyclic pattern of Ice Age glacial
maximums which each last
about 100,000 years, separated by intervening warm
interglacials, each lasting
about 12,000 years.
Most of the long-term
climate data collected from
various sources also shows a strong correlation
with the three astronomical
cycles which are together known as the
Milankovich cycles. The three Milankovich
cycles include the tilt of the
earth, which varies over a 41,000 year period;
the shape of the earth’s
orbit, which changes over a period of 100,000 years;
and the Precession of
the Equinoxes, also known as the earth’s ‘wobble’, which
gradually rotates
the direction of the earth’s axis over a period of 26,000
years. According
to the Milankovich theory of Ice Age causation, these three
astronomical
cycles, each of which effects the amount of solar radiation which
reaches
the earth, act together to produce the cycle of cold Ice Age maximums
and
warm interglacials.
Elements of the astronomical theory of Ice Age
causation were first presented by the French mathematician Joseph Adhemar in
1842, it
was developed further by the English prodigy Joseph Croll in
1875,
and the theory was established in its present form by the Serbian
mathematician
Milutin Milankovich in the 1920s and 30s. In 1976 the
prestigious journal
“Science” published a landmark paper by John Imbrie,
James Hays, and Nicholas
Shackleton entitled “Variations in the Earth's
orbit: Pacemaker of the Ice
Ages,” which described the correlation which the
trio of scientist/authors had
found between the climate data obtained from
ocean sediment cores and the
patterns of the astronomical Milankovich
cycles. Since the late 1970s, the
Milankovich theory has remained the
predominant theory to account for Ice Age
causation among climate
scientists, and hence the Milankovich theory is always
described in
textbooks of climatology and in encyclopaedia articles about the
Ice Ages.
