Study: Heat From Megacities Making Winters Warmer
America's
climate change-obsessed media love to point to warmer winters in our country as
proof of Al Gore's infamous money-making scam.
A new study from the journal Nature Climate
Change reported by the Los Angeles Times Monday
finds that in North America and Asia, heat from megacities is playing a larger
part than anyone previously thought.
"So-called
waste heat produced by human activities in major urban centers has altered
aspects of the jet stream and other atmospheric systems, causing significant
warming in some regions and cooling in others," the Times reported of the
study.
"What
we found is that energy use from multiple urban areas collectively can warm the
atmosphere remotely, thousands of miles away from the energy consumption
regions," lead author Guang Zhang, a research meteorologist at
Scripps Institution of Oceanography in La Jolla, observed. "This is
accomplished through atmospheric circulation change."
Although
the overall heat produced might be small on a global scale, it is highly
concentrated, "and in many cases, positioned directly beneath major
atmospheric troughs and ridges."
According
to the study, winter temperatures in Russia and northern Asia have increased by
up to two degrees Fahrenheit as a result of this megacity heat. In the
northeastern United States - conveniently the center of America's global
warming-obsessed media! - and southern Canada, "the effect has raised
winter temperatures by more than a degree."
America's
media had a conniption fit recently when it was "reported" that 2012
was the "warmest year on record" for the 48 states on the U.S.
mainland.
Exactly how
much of an impact did all the heat coming from cities such as New York,
Philadelphia, Boston, Los Angeles, and San Francisco have?

Keep in
mind that the authors of this study believe their numbers are conservative
because they only studied heat from megacities.
When all of the world's heat sources are factored in, just how
much of the warming that we've seen since the magical year 1850 - this is the
year climate alarmists love to begin their calculations from! - is due to urbanization
and NOT carbon dioxide?
Be
advised that the authors of this study are not contesting global warming
orthodoxy.
However,
skeptics have noted for decades that there are many factors behind the global
temperature rise since 1850, and that pinning the blame on a trace,
naturally-occurring, necessary to life gas defies scientific reason.
This
study goes to support such skepticism.
The only
question remaining is how much play it will get from media hellbent on ignoring
all reports that go against their climate ideology.
