History: Much Warmer in the Past Without Human Activity to Blame by Bob Ellis

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?


Article continues below this advert:

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.
