What They Haven’t Told You about Climate Change|5 Minute Vid…
Since time immemorial, our environment has been and will constantly be changing. Patrick Moore explains why “climate modification,” far from being a recent human-caused catastrophe, is, for a myriad of complicated factors, a truth of life on Planet Earth.

Script:
The only constant … is change.
That’s real about life. And it’s true about the environment. The environment has actually been continuously altering since the earth was formed 4.6 billion years ago.
In just the past 2000 years, we have actually seen the Roman Warm Period, when it was warmer than today … Then came the cooler Dark Ages … Followed by the Medieval Warm duration, when it was at least as warm as today … Then we had the Little Ice Age– that drove the Vikings out of Greenland. That’s a lot of changes.
Throughout the past 400,000 years there have been four major durations of glaciation– implying that large sheets of ice covered a good part of the world– interrupted by quick interglacial durations. We are in among those periods today. This is all part of the Pleistocene Ice Age which began in earnest two and a half million years ago. It’s still going on, which indicates that we are still living in an ice age. That’s the factor there’s a lot ice at the poles. Thirty million years ago the earth had no ice on it at all.
So, then, what about carbon dioxide, the excellent villain of the Global Warming alarmists? Where does that fit in to this picture? Not as neatly as you might think.
Temperatures and co2 levels do disappoint a strong correlation. In fact, over very long time spans– periods of numerous millions of years– they are frequently completely out of sync with each other.
Over and over once again, within essentially whenever frame, we find the climate altering– for reasons we do not totally understand. We do know there are many more aspects in play than simply the concentration of CO2 in the environment– elements such as the shape and size of the earth’s elliptical orbit around the sun, activity from the sun, and the quantity of wobble or tilt in the earth’s axis, amongst lots of others. Even the relatively brief 300-year period from the peak of the Little Ice Age to the present has actually not been consistent. The most recent trend has been a warming one, however it began almost a century before there were substantial co2 emissions from burning fossil fuels. And, there has actually been no considerable warming trend in the 21st century. Contrary to media headings, the pattern over the past couple of decades has been essentially flat.
Human-caused CO2 emissions are greater than ever. About 25 percent of all the CO2 emissions from human sources have happened throughout this duration of no net warming.
Will the temperature level resume an upward pattern? Will it remain flat for a lengthy period? No one understands.
