A commenter on my piece about the new documentary “Not Evil, Just Wrong” provided a link to a video clip about the natural, cyclic and historical nature of climate change on our planet.

I’ve seen and heard much of this information before from various sources, but it’s fairly safe to say a number of people may not have. Given the astonishing amount of ignorance thrown around in pop culture about anthropogenic global warming, remarkably absence is any realization that temperatures have been going up and down drastically on earth for hundreds and even thousands of years.

Apostles of anthropogenic global warming (AGW) would have us believe that the planetary warming we’ve seen in the last 15-20 years (which has leveled off in the last few years, incidentally) is “undoubtedly” caused by human activity.  How do they know this?  Well, humans invented industry and internal combustion engines within the last 100 years, and it’s gotten warmer in the last 100 years.  This is the obvious conclusion, right?

One of the most compelling historical facts presented in the clip below is a historical fact I have cited countless times in recent years.  Greenland, which is currently almost entirely covered in ice, was once warm enough for the Vikings to settle, build thriving communities and even grow vineyards.

Obviously the world was much, much, MUCH warmer about 1,000 years ago…looooong before internal combustion engines and any time of industry was constructed.

In other words, you can’t blame this much greater period of global warming on the SUV-driving capitalists.

And if the planet was much warmer in the past, obviously with no industrial cause to blame it on, the next logical step is to look at the solar data and how solar activity interacts with the earth’s terrestrial systems.  Incidentally, solar data tracks with and backs up natural causes of warming.

From the video’s YouTube description:

This video sets aside doomsday alarmism and political axe-grinding to look at the science behind the history of climate change on earth. An examination of early Viking colonies on Greenland, wiped out by a period of global cooling, enables scientists to draw important conclusions about our current phase in the climate cycle. What we learn in this program is that earth’s climate is always changing – from The Middle Ages and the “Little Ice Age” to the modern warming that has been going on since 1850 (well before human-generated CO2 began increasing in our atmosphere).

Dr. Willie Soon Ph.D., an Astrophysicist from the Harvard-Smithsonian Center for Astrophysics and Dr. David Legates Ph.D., a Climatologist from the Center from Climate Research at the University of Delaware provide an easy-to-follow review of current climate science, which suggests that the sun’s irregular patterns and other natural forces are the major sources of climate change.

  1. …the rest of the story. The important correlation between warming and cooling is the sunspot peak frequency, not the actual number of spots.Cosmic radiation is at its highest ever measured. This is happening because the earth’s magnetic shield is down, as a consequence, climate is changing (and always will). The climate celebrities, however, are linking climate and the economy. We can likely kick much of the carbon economy sometime late the twenty-first century, but we must not rush to judgement for the wrong reason. Yes, there has been warming to end the Ice Age. Climate is a chaotic system; the facts, however, do not support CO2 as a serious ‘pollutant’. In fact, it is plant fertilizer and seriously important to all life on the planet. It is the red herring used to unwind our economy. That issue makes the science relevant.

    Sulphate from volcanoes can have a catastrophic effect, but water vapour is far more important. Water vapour (0.4% overall by volume in air, but 1 – 4 % near the surface) is the most effective green house blanket followed by methane (0.0001745%). The third ranking gas is CO2 (0.0383%), and it does not correlate well with global warming or cooling either; in fact, CO2 in the atmosphere trails warming which is clear natural evidence for its well-studied inverse solubility in water: CO2 dissolves rapidly in cold water and bubbles rapidly out of warm water. The equilibrium in seawater is very high; making seawater a great ’sink’; CO2 is 34 times more soluble in water than air is soluble in water.

    CO2 has been rising and Earth and her oceans have been warming. However, the correlation trails. Correlation, moreover, is not causation. The causation is under scientific review, however, and while the radiation from the sun varies only in the fourth decimal place, the magnetism is awesome.

    “Using a box of air in a Copenhagen lab, physicists traced the growth of clusters of molecules of the kind that build cloud condensation nuclei. These are specks of sulphuric acid on which cloud droplets form. High-energy particles driven through the laboratory ceiling by exploded stars far away in the Galaxy – the cosmic rays – liberate electrons in the air, which help the molecular clusters to form much faster than climate scientists have modeled in the atmosphere. That may explain the link between cosmic rays, cloudiness and climate change.”

    As I understand it, the hypothesis of the Danish National Space Center goes as follows: quiet sun allows the geomagnetic shield to drop. Incoming galactic cosmic ray flux creates more low-level clouds, more snow, and more albedo effect as more is heat reflected resulting in a colder climate. Active sun has an enhanced magnetic field which induces Earth’s geomagnetic shield response. Earth has fewer low-level clouds, less rain, snow and ice, and less albedo (less heat reflected) producing a warmer climate.

    That is how the bulk of climate change works, coupled with (modulated by) sunspot peak frequency there are cycles of global warming and cooling like waves in the ocean. When the waves are closely spaced, all the planets warm; when the waves are spaced farther apart, as they have been for this century, all the planets cool.

    The change in cloud cover is only a small percentage, and the ultimate cause of the solar magnetic cycle may be cyclicity in the Sun-Jupiter centre of gravity. We await more on that.

    Although the post 60s warming period appears to be over, it has allowed the principal green house gas, water vapour, to kick in with more humidity, clouds, rain and snow depending on where you live to provide the negative feedback that scientists use to explain the existence of complex life on Earth for 550 million years. Ancient sedimentary rocks and paleontological evidence indicate the planet has had abundant liquid water over the entire span. The planet heats and cools naturally and our gasses are the thermostat. Nothing unusual is going on except for the Orwellian politics.

  2. Thinking people easily see through the lies of this latest “catastrophe” of so-called global warming, which is designed to further help usher in global governance. This campaign of earth-worship, begun by the world elites through the goons in the United Nations, is nothing more than a propaganda stunt that ultimately ends in enslavement of the entire world by an elite group of shadow men. To them and their shills like Al Gore, the science doesn't matter. When you read the Rio Declaration and Agenda 21, you see them clearly state that even if the “science” is not conclusive to their claims, they're going to push it anyway for their larger purpose. It has nothing to do with “saving the planet” and everything to do with power, money and control of the people.
