In our continuing look at The Great Global Warming Swindle, we move from Part 3 into Part 4 today.
At the end of Part 3, we began looking at solar physicist Dr. Piers Corbyn’s successful efforts to predict climate change based on solar activity. Part 4 picks up with a look at the “Maunder Minimum” in the 1600s and 1700s when sunspots became very rare…and temperatures also dropped very low.
Corbyn said he gambled on the weather through the William Hill gaming organization, and won again and again.
Over the course of the Twentieth Century, solar activity and temperature tracked remarkably close together.
But Professor Eigil Friis-Christensen of the Danish National Space Center wanted to look even farther back to see if there was a long-standing pattern, so they looked at 400 years worth of observations. Again, temperatures and solar activity tracked with one another.
Professor Nir Shaviv of the Institute of Physics at the University of Jerusalem took a look at information concerning cosmic rays and cloud formation (cosmic rays play an important role in cloud formation) along with temperature records.
They found that when cosmic rays went down, temperatures went up, and vice versa. Which makes perfect sense, since increased solar activity tends to push cosmic rays away from earth, and with the (a) increase in solar activity, and (b) increase in temperatures, and (c) decrease in cosmic rays, we saw (d) less cloud formation.
CO2 and temperature do not correlate well, but solar activity and temperature are remarkably similar.
So why the hysteria over the theory of anthropogenic (man-made) global warming the the religious belief that human industrial activity is causing the planet to warm dangerously?
The film turns to the origin of the theory to help answer this vexing question. The examination begins in the 1970s with information like “The Weather Machine” which was shown on the BBC, predicting global cooling, a coming ice age, etc.
About the only person saying anything to the contrary was a Swedish scientist who predicted that industrial activity producing large amounts of carbon dioxide might warm the earth. He was written off by most of the scientific community, since the “settled science” of that day was “global cooling”…until temperatures started to rise.
And a new religion of anthropogenic global warming (AGW) was born.
