Dear Sir:
Your paper today states atmospheric
carbon dioxide has reached 400 parts per million, a level that “has
not been this high for at least 3 million years.” But 90,000 (!)
measurements of atmospheric carbon dioxide were made between the
years 1812 and 1961 and published in 175 technical papers. These
measurements were made by top scientists, including two Nobel Prize
winners, using techniques that are standard textbook procedures.
Ernst Georg Beck made a monumental compilation of these carbon
dioxide measurements and graphed five-year averages, which smooth
irregularities and show trends rather than an individual year that
might be an anomaly. His work shows an average of 440 ppm carbon
dioxide for the years 1820 and 1940.
Furthermore, ice cores show over 400
ppm in 1700 A.D. and 200 A.D., as well as 10,000 years ago. Samples
from Camp Century (Greenland) and Byrd Camp (Antarctica) range from
250 to nearly 500 ppm over the last 10,000 years.
There is abundant other evidence that
global warming alarmism is false, but you won't print:
The above is based on sediments from
the Sargasso Sea. It shows the earth was much warmer 500 and 900
years ago and that there were even warmer times 500 BC and 1000 BC.
All of these times had no factories or automobiles. They also had far
smaller human populations, who devoted much less land to agriculture
and cut far fewer trees. Note, too, that now we have barely reached
the average temperature for the last 3,000 years. The chart also
shows the current warming trend began more than 250 years ago, before
the Industrial Revolution. It was a natural recovery from the Little
Ice Age.
This puts “global warming” (the
slight upturn in the lower right) in perspective with the last 4,000
years of temperature in Greenland.
This intriguing chart by J. Oerlemans
shows records of 169 glaciers. It shows they have been receding since
1750, with the trend accelerating after about 1820. The electric
light bulb and the telephone hadn't been invented yet. (Thomas Edison
wasn't even born.) The first commercial electric power plant was not
built until 1881-82. Henry Ford began assembly line production in
1913, but by then half of the glacier loss from 1800 to 2000 had
already occurred. And 70 percent of the glacier shortening occurred
before 1940.
Siberia's Lake Baikal is the world's
deepest lake. It contains more water than all five of North America's
Great Lakes combined. Fed by over 300 rivers and far from the
moderating effects of any ocean, it offers a pristine, uninterrupted
sedimentary record that permits a highly accurate reconstruction of
temperatures over a broad area.
Anson MacKay, author of the study,
says: (1) “Warming in the Lake Baikal region commenced before rapid
increases in greenhouse gases;” he dates the warming from around
1750 A.D.,, long before industrial development led to the increase of
greenhouse gases. (2) The warming trend began from one of the coldest
periods in the last 800,000 years. (3) These coldest periods in the
past were always followed by sharp, large temperature increases that
couldn't possibly have been caused by human activity. (4) The latest
warming is puny compared to the many much warmer periods in the past.
You newspaper never prints any of these
scientific facts—but has plenty of room for the latest propaganda
about global warming and carbon dioxide.
Yours truly,
