We've all been harangued at least once by a pompous greener-than-thou lefty -- like a devout Christian righty berating you, but with more disdain.
What's interesting though is how many climate scientists don't agree with the hokum that is now being peddled at us from politicians and businesses as well the typical green lobby regarding the efficacy of carbon in relation to weather temperatures.
To wit, this article, in a Candian newspaper written by one R. Timothy Patterson. Highlights of the article are
"Climate stability has never been a feature of planet Earth. The only
constant about climate is change; it changes continually and, at times,
quite rapidly. Many times in the past, temperatures were far higher
than today, and occasionally, temperatures were colder. As recently as
6,000 years ago, it was about 3C warmer than now. Ten thousand years
ago, while the world was coming out of the thousand-year-long "Younger
Dryas" cold episode, temperatures rose as much as 6C in a decade -- 100
times faster than the past century's 0.6C warming that has so upset
environmentalists."
"Our finding of a direct correlation between variations in the
brightness of the sun and earthly climate indicators (called "proxies")
is not unique. Hundreds of other studies, using proxies from tree rings
in Russia's Kola Peninsula to water levels of the Nile, show exactly
the same thing: The sun appears to drive climate change."
"In a series of groundbreaking scientific papers starting in 2002,
Veizer, Shaviv, Carslaw, and most recently Svensmark et al., have
collectively demonstrated that as the output of the sun varies, and
with it, our star's protective solar wind, varying amounts of galactic
cosmic rays from deep space are able to enter our solar system and
penetrate the Earth's atmosphere. These cosmic rays enhance cloud
formation which, overall, has a cooling effect on the planet. When the
sun's energy output is greater, not only does the Earth warm slightly
due to direct solar heating, but the stronger solar wind generated
during these "high sun" periods blocks many of the cosmic rays from
entering our atmosphere. Cloud cover decreases and the Earth warms
still more.
The opposite occurs when the sun is less bright. More
cosmic rays are able to get through to Earth's atmosphere, more clouds
form, and the planet cools more than would otherwise be the case due to
direct solar effects alone. This is precisely what happened from the
middle of the 17th century into the early 18th century, when the solar
energy input to our atmosphere, as indicated by the number of sunspots,
was at a minimum and the planet was stuck in the Little Ice Age. These
new findings suggest that changes in the output of the sun caused the
most recent climate change. By comparison, CO2 variations show little
correlation with our planet's climate on long, medium and even short
time scales."
its weakest Schwabe solar cycle of the past two centuries, likely
leading to unusually cool conditions on Earth. Beginning to plan for
adaptation to such a cool period, one which may continue well beyond
one 11-year cycle, as did the Little Ice Age, should be a priority for
governments. It is global cooling, not warming, that is the major
climate threat to the world."
