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.
