A
new study is certain to provoke fierce reactions from the vast global
establishment devoted to spending billions of dollars a year fighting
atmospheric release of CO2. Demonizing the production of energy from the
burning of organic fuel has providing a handy tool to all those who seek to tax
and regulate economic activity even further. But researcher Henrik Svensmark,
from The Technical University of Denmark long has been a critic of climate
models that downplay the role of solar activity. And now, he has conducted
experiments that provide scientific weight to his theories by identifying the
feedback mechanism through which solar activity works.
Svensmark
and colleagues showed this in a massive experiment to simulate the interaction
of cosmic rays with the upper atmosphere, and were able to model the physical
mechanism. His study was published in the journal Nature
Communications and ably summarized by Graham Lloyd of the
Australian, reprinted in the Global
Warming Policy Forum:
He does not dispute that increased levels of carbon
dioxide in the atmosphere have a warming impact on the climate.
But his findings present a challenge to estimates of
how sensitive the climate is to changes in carbon dioxide levels in the
atmosphere.
Professor Svensmark says his latest findings were
consistent both with the strong rise in the rate of global temperature change
late last century and a slowdown in the rate of increase over the past 20
years.
‘’It gives a physical foundation to the large body of
empirical evidence showing that solar activity is reflected in variations in
Earth’s climate,” a media statement accompanying the scientific report said.
“For example, the Medieval Warm Period around year
1000AD and the cold period in the Little Ice Age 1300-1900 AD both fits changes
in solar activity,” it said.
“Finally we have the last piece of the puzzle of why
the particles from space are important for climate on Earth,” it said.
The study reveals how atmospheric ions, produced by
the energetic cosmic rays raining down through the atmosphere, helps the growth
and formation of cloud condensation nuclei — the seeds necessary for forming
clouds in the atmosphere.
More cloud condensation nuclei mean more clouds and a
colder climate, and vice versa.
“Since clouds are essential for the solar energy
reaching the surface of the Earth the implications are huge for our
understanding of why climate has varied in the past and also for a future
climate changes,” the statement said.
Professor Svensmark said it had until now wrongly been
assumed that small additional nucleated aerosols would not grow and become
cloud condensation nuclei, since no mechanism was known to achieve this.
The research team tested its ideas experimentally in a
large cloud chamber.
Data
was taken over a period of two years with total 3100 hours of data sampling.
Illustration of
cosmic rays interacting with the atmosphere. A proton with energy of 100 GeV
interact at the top of the atmosphere and produces a cascade of secondary
particles who ionize molecules when traveling through the air. One 100 GeV
proton hits every m2 at the top of the atmosphere every second.
The
defensive case on global warming (now aka "climate change") has
always been that "this is basic physics," meaning you can show it in
the laboratory. But Richard Feynman long ago warned that "basic
physics" is inherently oversimplified, because ALL lab experiments are far
simpler than nature. Which is why physics tells us little about
biological evolution or human behavior, for example. Or the atmosphere, where
models are really guesswork.
All
the scare "studies" are not experiments at all --- they are computer
simulations, and they are just about as accurate as computer simulations of the
stock market. The corrupting effect of the climate fraud has been enormous.
Tony Blair, who was one of the main instigators, said at the Copenhagen
conference that the truth didn't really matter. What's the big deal?
Well,
one big deal is that a small percentage of that cost could have been spent on
bringing clean water to African villages where people die from infections.
Bjorn Lomborg has been trying to make that point forever, and the fraudulent
money establishment has been closing its ears and eyes. So much for liberal
compassion.
