I Wish
the Earth Were Warming It Would Save a Lot of Lives

First, if
the earth was warming at a rate of about 1 or even 2 degree per
century in recent decades, there are reasons to believe thats
slowed or stopped. One of those reasons is that the global
warming fanatics have abruptly shifted their rhetoric, adopting
instead the new nonsense euphemism climate change. This
is a clear attempt at inoculation: If it turns out the globe is
indeed cooling again, they will merely take their same pre-set,
ulterior agenda huge energy tax hikes to finance bigger government,
cripple capitalism, and destroy the freedom-giving automobile, instead
forcing everyone to pile like lemmings into mass transit
and declare that an identical agenda is now needed to fight
global cooling
and that we dare not waste any
time in debate! Hee-haw!
Furthermore,
even if the earth did warm a bit in recent decades, theres
no reason to believe mans activities played a substantial
role. Carbon dioxide is not a particularly effective greenhouse
gas, nor the most prevalent. (Water vapor is.) Furthermore, the
amount of atmospheric carbon dioxide generated by mans activities
is infinitesimal. Astronomers tell us that when the earth undergoes
modest global warming, Mars does, too. Its unlikely Mars gets
warmer because anyone there is burning coal or driving SUVS. The
more likely culprit for the parallel warming of the two planets
is solar activity.
And third,
even if the earth is warming and mankind somehow contributed to
the process, no regulations promulgated by the U.S. government can
have any useful impact, since the U.S. government has no authority
over the activities of fast-industrializing India and China, where
new coal-fired generators come on line weekly.
But let us,
for the sake of argument, stipulate to all three flimsy (though
required, if their theory is to hold water) links in this chain.
Let us pretend, in other words, that we are the skeptical
reporters of todays Washington Post and New
York Times, and stipulate that 1) The earth is warming noticeably
and will continue to do so for centuries; 2) carbon dioxide generated
by mankind plays a dominant role in this process, and 3) some set
of expensive, draconian regulations which can be promulgated and
enforced by the EPA or a high-handed U.S. White House can end or
substantially reduce global warming.
OK. Were
still left with an important question: Should that be done? That
is to say: Is there any scientific reason (science fiction films
with computer-generated tidal waves flooding the Empire State Building
to the 30th floor do not count) to believe that moderate global
warming, in the range of 1 to 4 degrees centigrade over the next
couple of centuries, will do more harm than good to the health and
safety of mankind?
And the answer
is, um
no.
The maximal
increase in atmospheric CO2 from combustion of hydrocarbon fuels
cannot harm human health directly, points out Howard Maccabee,
Ph.D., M.D., in the November, 2008 newsletter of the group he heads,
the Tucson-based Doctors for Disaster Preparedness. Rather, The
hypothetical mechanism of harm now being used to justify EPA
intervention under the Clean Air Act, is through global
warming.
Many
scientists dispute the predictions from the U.N. IPCC computer models,
Dr. Maccabee notes. However heres the killer
even if the models are correct, warming would be a net benefit
to human health. Hence the EPA has no legitimate authority to regulate
CO2 emissions.
The doctor
then proceeds to spell that out.
The U.N. Intergovernmental
Panel on Climate Change (a political organization, please note,
not a scientific one) gives an average temperature increase of 4.5
Centigrade as a worst-case scenario. There is historical precedent
for increases of this magnitude, Dr. Maccabee points out. Stalagmite
proxies in South Africa indicate increases of up to 4 C in the Medieval
Warm Period (formerly called the Medieval Climate Optimum). Because
of the urban heat island effect, large cities have shown temperature
increases as much as 3 C (e.g. Tokyo 18762004) to 4 C (New
York City 18222000). We thus have data to evaluate the health
effects of climate change.
In 1995, Thomas
Gale Moore published the first of his pioneering efforts, Why
Global Warming Would be Good for You, and in 1998, Health
and Amenity Effects of Global Warming. He estimated that a
temperature increase of 2.5 C in the U.S. would cause a drop of
40,000 deaths per year from respiratory and circulatory disease,
based on U.S. Mortality Statistics as a function of monthly climate
change.
In 1997, the
Eurowinter Group (W. R. Keatinge, G. C. Donaldson, et al.) published
Cold Exposure and Winter Mortality from Ischaemic Heart Disease,
Cerebrovascular Diseases, Respiratory Diseases and all Causes in
Warm & Cold Regions of Europe, DDP points out, again in
their newsletter of November, 2008. This was a landmark study
that elucidated the mechanisms of serious illness from cold, which
are dominated by hemoconcentration, which increases blood viscosity
(sludging). This can cause death from blockage of vessels
serving the heart and the brain, accounting for half of all excess
cold-related mortality.
This was followed
by Heart Related Mortality in Warm and Cold Regions of Europe:
Observational Study in the British Medical Journal in 2000
hardly a fringe or flaky publication. These two studies examined
mortality as a function of mean daily temperature in Athens, London,
and Helsinki, providing the most comprehensive collection of evidence
that mortality decreases as temperature increases, over most of
the current climate range in Europe.
In 2006, A.J.
McMichael et al. assume, in Climate Change and Human Health:
Present and Future Risks, that the maximum daily mortality
in higher temperature periods will be equal to or greater than the
maximum mortality in cold periods, resulting in heat-related deaths
increasing far more than the lives saved by warming of the cold
periods. But This hypothesis is inconsistent with U.S. data
showing that mortality due to cardiac, vascular, and respiratory
disease in winter is seven times greater than in summer, Dr.
Maccabee and Doctors for Disaster Preparedness now report. This
ratio is about nine to 10 in Europe, from the data of Keatinge,
et al.
The most comprehensive
daily all-cause mortality data as a function of the day of the year
is from Deschenes and Moretti in 2007. Mortality is maximum in January
and minimum in the warmest months of July and August. This
data strongly indicates that warming of average daily temperatures
would cause a decrease in mortality in winter far greater than the
slight increase of mortality from summer heat, the DDP conclude.
In early 2008,
the Department of Health of the UK released Health Effects
of Climate Change in the UK 2008, an update of previous reports
from 2001/2002, edited by Sari Kovats. They used IPCC models that
predicted 2.5 C to 3 C mean temperature increases in the U.K. by
2100. They found that there was no increase in heat-related deaths
from 19712002, despite warming in summers, suggesting that
the UK population is adapting to warmer conditions. But cold-related
mortality fell by more than a third in all regions. The overall
trend in mortality for the warming from 19712002 was beneficial.
They state, in summary, that Winter deaths will continue to
decline as the climate warms.
The data
from the Eurowinter Group (Lancet 1997) on mortality versus
temperature can be used for a quantitative estimate of mortality
benefits from warming, DDP conclude. This would lead
to an estimated 25,000 to 50,000 fewer deaths in the U.S. per year
for a 1 C temperature rise. This can be compared to 30,000 deaths
per year from breast cancer, 30,000 for prostate cancer, or about
40,000 from motor vehicle accidents.
Furthermore,
Heat deaths often represent displacement (i.e.
weakened people die a few days or weeks before prior expectation),
but deaths due to cold usually result in months to years of life
lost, the newsletter points out. Thus the benefits in
life expectancy from warming in cold periods may be much more than
nine times greater than life span lost in warm periods.
And thats
before we even look at the advantages of being able to grow food
closer to the Arctic Circle.
Global warming
(if it should continue) will save lives lots of them. Nor
is this counterintuitive. Since our early ancestors developed and
prospered in warm climates most likely in equatorial Africa
why shouldnt it hold true that our species will do
best in moderately warmer climates?
Humans are
masters of adaptation, but it still takes a lot more work to survive
in the cold. The climate change we should really worry
about is the next Ice Age, which could see everything north of Columbus,
Ohio covered by an ice shelf a mile thick.
Do the global
warming fanatics think we can prevent that by burning lots
of coal and putting lots of miles on our SUVs? If so, shouldnt
we start right now, just in case?
Meantime, can
someone explain again why Barack Obama gets to play commander-in-chief
of the auto industry, wave his magic wand, and declare that
an industry already in bankruptcy will have to charge an extra $1,500
per vehicle to limit CARBON DIOXIDE emissions to fight global
warming
when it turns out global warming would save
human lives?
