||Talk - Ice Age
There is a conventional view about ice ages,
which most people support. It goes like this: we are currently
living in an ice age; we have been for 40 million years. Within
ice ages there are temperate periods and severe periods. These
are called ‘interglacial’ and ‘glacial’.
During interglacial periods ice sheets diminish in size. In
glacial periods they spread. We are currently in an interglacial
period. We have been for about 10,000 years. Both ice ages,
and the glacial/interglacial periods within them, are caused
by various factors, including the atmospheric condition (notably
the mixture of methane and CO2); differences in the Earth’s
orbit around the sun, and the position of the continental plates
relative to the poles.
This afternoon, Matthew Hepburn, secretary of astronomy group
PONLAF, vehemently refutes this theory, which he considers to
be Anglo-centric. He points to evidence, that has been well
known for more than 100 years, and outlines a radical new explanation
for ice ages. Incidentally, he promises to clear up a nagging
problem in geomagnetism. He will also speak at length about
global warming, a connected subject, if he is asked. It’s
an important talk, then, and we are assured it won’t be
pitched too far above the layman’s head.
