I have been going on about the lack of Solar activity for a while now,
and it strikes me that my first, and only, real Debate on that "other
Forum" was on Man Made Global Warming, so this seems to be something
that may help prove my side of this discussion, once and for all...

More on Cosmic Rays   [Edward John Craig]

Hudson’s Dennis Avery in the Canada Free Press (hat-tip to Tom
Nelson).

A Canadian scientist says the largest known hole in the ozone will
occur over the South Pole in the next week. If that happens, it will
help us understand global warming.

Dr. Qing-Bin Lu, of Canada’s University of Waterloo, says NASA
satellites and laboratory measurements show cosmic rays are the real
cause of the seasonal hole in the earth’s ozone layer over the
Antarctic. Cosmic rays are tiny, invisible, high-energy particles from
exploding stars which constantly strike the earth — and people. Cosmic
rays probably cause some of our cancers, by altering the DNA inside
our bodies.

However, if Dr. Qing-Bin Lu and others are correct, they also are
connected to climate change. The number of cosmic rays hitting the
earth varies sharply based on the activity level of the sun and the
size of the magnetic wind it projects out into space. A weak sun means
a weak magnetic wind and more cosmic rays striking earth. Britain’s
BBC recently reported that the solar wind is now blowing at the
weakest rate in more than 50 years, and is also 13 percent cooler than
it was 15 years ago.


The ozone layer is important because it absorbs most of the sun’s high-
frequency ultraviolet light, protecting us from skin cancers and
cataracts. In the 1980s, eco-activists told us the hole in the
Antarctic ozone had been caused by man-made chemicals released from
the chlorofluorocarbons once used in our refrigerators and air
conditioners.

Fear of losing the ozone layer’s health protection led to the Montreal
Protocol, which has banned CFCs since 1989. But the ban failed to
change behavior of the ozone layer over the Antarctic.

Dr. Lu says that NASA satellites demonstrate that cosmic rays cause
drastic reactions in chlorine compounds inside clouds over the Polar
Regions. The satellite data now cover two full 11-year solar cycles,
from 1980–2007.

“This finding, combined with laboratory measurements, provides strong
evidence of the role of cosmic-ray-driven reactions in causing the
ozone hole, and resolves the mystery of why a large discrepancy
between the sunlight-related photochemical model and the observed
ozone depletion exists,” says Lu.

Cosmic rays are also connected to climate change. In 1998, Henrik
Svensmark of the Danish Space Research Institute filled a reaction
chamber with the earth’s mix of atmospheric gases, and turned on a UV
light to mimic the sun. He was amazed as the cosmic rays coming
through the building’s walls quickly filled the chamber with huge
numbers of microscopic, electrically charged droplets of water and
sulfuric acid — the “cloud seeds” that help create low, wet, cooling
clouds in the earth’s atmosphere. Since such clouds often cover 30
percent of the earth’s surface, they can play a crucial role in the
planet’s warming or cooling.

Currently, the World Meteorological Organization uses the
photochemical model to predict that the Antarctic springtime ozone
hole will increase by another 5–10 percent by 2020. In sharp contrast,
Dr. LU says the severest ozone loss will occur over the South Pole
this month — with another large ozone-triggered hole occurring around
2019.

If the South Pole gets an ozone-hole maximum in the coming weeks, it
will strengthen the case for cosmic rays, and endorse a Modern Warming
driven by solar variations rather than human-emitted CO2. The solar
model is already endorsed by oxygen isotopes in ice cores from both
Greenland and the Antarctic, by microfossils in the sediments of nine
oceans and hundreds of lakes worldwide, and by cave stalagmites from
every continent plus New Zealand.

The case for a solar-driven climate is also strengthened by a drop in
global temperatures over the past 18 months: The temperature decline
had been forecast by the sunspot index since 2000, but was not
predicted by the global climate models.
