Global Warming Is a Fraud

As the years
pass and data accumulate, it is becoming evident that global warming
is a fraud. Climate change is natural and ongoing, but the Earth
has not warmed significantly over the last thirty years. Nor has
there been a single negative effect of any type that can be unambiguously
attributed to global warming.

As I write,
satellite data show that the mean
global temperature
is the same that it was in 1979. The extent
of global
sea ice
is also unchanged from 1979. Since the end of the last
Ice Age, sea level has risen more than a hundred meters. But for
the last three years, there has been no rise in sea
level
. If the polar ice sheets are melting, why isn’t sea level
rising? Global warming is supposed to increase the severity and
frequency of tropical storms. But hurricane
and typhoon activity
is at a record low.

Every year
in the US, more than forty thousand people are killed in traffic
accidents. But not one single person has ever been killed by global
warming. The number of species that have gone extinct from global
warming is exactly zero. Both the Antarctic and Greenland Ice Sheets
are stable. The polar bear population is increasing. There has been
no increase in infectious disease that can be attributed to climate
change. We are not currently experiencing more floods, droughts,
or forest fires.

In short, there
is no evidence of any type to support the idea that we are entering
an era when significant climate change is occurring and will cause
the deterioration of either the natural environment or the human
standard of living.

Why do people
think the planet is warming? One reason is that the temperature
data from weather stations appear to be hopelessly contaminated
by urban heat effects. A survey
of the 1221 temperature stations
in the US by meteorologist
Anthony Watts and his colleagues is now more than 80 percent complete.
The magnitude of putative global warming over the last 150 years
is about 0.7 C. But only 9 percent of meteorological stations
in the US are likely to have temperature errors lower than 1 C.
More than two-thirds of temperature sensors used to estimate global
warming are located near artificial heating sources such as air
conditioning vents, asphalt paving, or buildings. These sources
are likely to introduce artifacts greater than 2 C into the
temperature record.

Another cause
of global warming hysteria is the infiltration of science by ideological
zealots who place politics above truth. Earlier this month, the
Obama administration issued a report
that concluded global warming would have a number of deleterious
effects on the US. In 1995, one of the lead authors of this report
told me that we had to alter the historical temperature record by
“getting rid” of the Medieval Warm Period.

The Obama report
refers to — six times — the work of a climate scientist named Stephen
H. Schneider. In 1989, Schneider told Discover magazine that
“we have to offer up scary scenarios, make simplified, dramatic
statements, and make little mention of any doubts we might have.”
Schneider concluded “each of us has to decide what the right balance
is between being effective and being honest.” Schneider’s position
is not unusual. In 2007, Mike Hulme, the founding director of the
Tyndall Center for Climate Change Research in Britain, told the
Guardian newspaper that “scientists and politicians must
trade truth for influence.”

While releasing
a politicized report that prostitutes science to politics, the Obama
administration simultaneously suppressed an internal EPA report
that concluded there were “glaring inconsistencies” between the
scientific data and the hypothesis that carbon dioxide emissions
were changing the climate.

If we had an
appreciation for history, we would not be fooled so easily. It has
all happened before, albeit on a smaller scale in an age where people
had more common sense. On May 19, 1912, the Washington Post
posed these questions: “Is the climate of the world changing? Is
it becoming warmer in the polar regions?” On November 2, 1922, the
Associated Press reported that “the Arctic Ocean is warming
up, icebergs are growing scarcer and in some places the seals are
finding the waters too hot.” On February 25, 1923, the New York
Times concluded that “the Arctic appears to be warming up.”
On December 21, 1930, the Times noted that “Alpine glaciers
are in full retreat.” A few months later the New York Times
concluded that there was “a radical change in climatic conditions
and hitherto unheard of warmth” in Greenland. About the only thing
that has changed at the Times since 1930 is that no one working
there today is literate enough to use the word “hitherto.”

After the warm
weather of the 1930s gave way to a cooling trend beginning in 1940,
the media began speculating on the imminent arrival of a new Ice
Age. We have now come full circle, mired in a hopeless cycle of
reincarnated ignorance. H. L. Mencken understood this process when
he explained “the whole aim of practical politics is to keep the
populace alarmed by an endless series of hobgoblins, most of them
imaginary.”
