Top 10 Climate Myth-Busters for 2007
Thursday , December 27, 2007

"I've made up my mind. Don't confuse me with the facts." That saying
most appropriately sums up the year in climate science for the fanatic
global warming crowd.
As Al Gore, the United Nations, grandstanding politicians and
celebrities, taxpayer-dependent climate researchers, socialist-minded
Greens, climate profiteers and other members of the alarmist railroad
relentlessly continued their drive for greenhouse gas regulation in
2007, the year's scientific developments actually pointed in the
opposite direction. Here's the round-up:
1. Cracked crystal balls. Observed temperature changes measured over the
last 30 years don't match well with temperatures predicted by the
mathematical climate models relied on by the U.N.'s Intergovernmental
Panel on Climate Change (IPCC), researchers reported.
The models predict significantly warmer atmospheric temperatures than
actually occurred, despite the availability of more and better quality
data and improved modeling efforts since the late-1970s.
"We suggest, therefore, that projections of future climate based on
these models be viewed with much caution," the researchers concluded.

2. The big yellow ball in the sky. The Sun may have contributed 50
percent or more of the global warming thought to have occurred since
1900, according to a new historical temperature reconstruction showing
more variation in pre-industrial temperatures than previously thought.
The researchers found that "the climate is very sensitive to solar
changes and a significant fraction of the global warming that occurred
during the last century should be solar induced." Read more...
3. Pre-SUV warming. Another new temperature reconstruction for the past
2,000 years indicates that globally averaged temperature 1,000 years ago
was about 0.3 degrees Celsius warmer than the current temperature. Since
that climatic "heat wave" obviously wasn't caused by coal-fired power
plants and SUVs, the current temperature is quite within natural
variability, deflating alarmists' rash conclusions about the warming of
the past 50 years. Read more...
4. A disciplined climate. Runaway global warming -- the alarmist fantasy
in which a warmer global temperature causes climatic events that, in
turn, cause more warming and so-on in a never-ending positive feedback
loop -- was cornered by new data from researchers at the University of
Alabama-Huntsville (UAH). The new research sheds light on the mechanism
by which the atmosphere self-regulates. Read more...
5. A gnarly wipeout. Climate alarmists gleefully surfed a 2005 study
that claimed greenhouse gas emissions would slow Atlantic Ocean
circulation and cause a mini ice age in Europe. But an international
team of researchers reported that the intensity of the Atlantic
circulation may vary by as much as a factor of eight in a single year.
The decrease in Atlantic circulation claimed in the 2005study falls well
within this variation and so is likely part of a natural yearly trend,
according to the new study. Read more...
6. A pollution solution. A new study reported that the solid particles
suspended in the atmosphere (called "aerosols") that make up "brown
clouds" may actually contribute to warmer temperatures -- precisely the
opposite effect heretofore claimed by global warming alarmists.
"These findings might seem to contradict the general notion of aerosol
particles as cooling agents in the global climate system ...," concluded
the researchers. Read more...
7. Lazy temperature? Researchers reported that the rate of manmade
carbon dioxide (CO2) emissions was three times greater during 2000 to
2004 than during the 1990s. Since increasing atmospheric C02 levels
allegedly cause global warming, the new study must mean that global
temperatures are soaring even faster now than they did during the 1990s,
right?
Wrong. According to the most recent data from the U.S. Department of
Commerce's National Climatic Data Center, ever-changing global
temperatures are in no way keeping pace with ever-increasing atmospheric
carbon dioxide levels. Read more...
8. Don't plant that tree! Researchers reported that while tropical
forests exert a cooling influence on global climate, forests in northern
regions exert a significant warming influence on climate. Based on the
researchers' computer modeling, forests above 20 degrees latitude in the
Northern Hemisphere -- that is, north of the line of latitude running
through Southern Mexico, Saharan Africa, central India and the
southernmost Chinese Island of Hainan -- will warm surface temperatures
in those regions by an estimated 10 degrees Fahrenheit by the year 2100.
Read more...
9. The Tropical Arctic. Dutch researchers reported that during a period
of intense global warming 55 million years ago -- when the Arctic Ocean
was as warm as 73 degrees Fahrenheit -- there was a tremendous release
of greenhouse gases into the atmosphere. But which came first, the
warming or the greenhouse gases?
It was the warming, according to the researchers. Read more...
10. Much ado about nothing. In a report to Congress, the U.S.
Environmental Protection Agency revealed greenhouse gas regulation to be
quite the fool's errand. In estimating the atmospheric levels of
greenhouse gases 90 years from now under both a scenario where no action
is taken to reduce manmade emissions and a scenario where maximum
regulation is implemented, the estimated difference in average global
temperature between the two scenarios is 0.17 degrees Centigrade.
For reference purposes, the estimated total increase in average global
temperature for the 20th century was about 0.50 degrees Celsius.
That's what researchers have reported this year. And let's not forget
the spanking a British high judge gave Al Gore's movie for all its
scientific inaccuracies and the thrashing non-alarmist climate
scientists gave to alarmist climate scientists in a debate sponsored by
the New York debating society Intelligence Squared.
Al Gore and the alarmist mob claim the debate about the science of
global warming is "over." Given the developments of 2007, it's easy to
see why they would want it that way.

Thanks for posting the truth. Gore's global warming is a political
ploy, and not scientific. He has sure fooled a lot of people, though.
