An early Greenpeace activist who left the movement over its political drift says global warming and more atmospheric carbon is no cause for alarm.Patrick Moore, a senior fellow with the Frontier Centre for Public Policy (FCPP) made his comments in a YouTube livestream discussion with FCPP president David Leis.Moore, who received a PhD in Forestry at the University of British Columbia in 1974, was active in the early days of Greenpeace. He left the environmental activist group after they contemplated a campaign against chlorine, despite how its use in water purification advanced human health.The commentator, author, and former student of David Suzuki, says a long-term look at ecological history shows a warm earth is nothing new."Antarctica was forested, and the Arctic Ocean was ice free, full of life, with lots of trees growing on the islands," Moore said of the ancient past. "So, to say that the earth is, the climate is, getting too warm is absolutely ridiculous."Moore said another great irony of the "scare story" claims that atmospheric carbon dioxide is reaching new highs that will inevitably lead to global warming. He said carbon dioxide was formerly 10,000 parts per million and went steadily downward to 180 ppm in the most recent glacial maximum."This cyclical situation has been in order for two and a half million years, and there's absolutely no evidence whatsoever that that is going to change anytime soon," Moore saidd."When the earth is colder, CO2 declines. And then when the earth warms up, CO2 increases. And we've increased it to 425 parts per million...If it had gone down to 150 from 180 life would begin to die. And so we are, in fact, salvation of life.".Moore says contrary to popular belief, polar bears are thriving."In 1972, all the polar nations passed an international treaty to reduce the killing of polar bears...and since then, the polar bear population has increased by between five and ten times," he said.In 2016, scientists said 93% of coral in the Great Barrier Reef was bleaching due to heat stress. The enormity of the threat was overstated, Moore said."When they say, if it gets warmer, all the stuff that everything that's living in the warmest oceans now will die--no, they will continue to spread into the places where the water is colder," Moore explained.The earth is still emerging from the Little Ice Age that peaked around 1600 A.D., according to Moore, who humans are a "tropical species.""If it weren't for fire, shelter and clothing, all of which are artificial and man-made,...we couldn't come out of the tropics. We would die in southern Mexico, in a high altitude place," Moore explained."The last thing we are in is an earth that's too hot. This Earth was so much warmer for most of its existence."Moore says bad weather events highlighted on the Weather Channel do not mean storms and earthquakes will kill more people."It's totally ridiculous to say that," Moore said. "The number of people that have died in weather events has gone down by about 100% practically just in the last couple of hundred years when there weren't any early warnings for hurricanes, for example....and we build stronger structures now."In 2022, Moore wrote his book entitled "Fake Invisible Catastrophes and Threats of Doom." Now 77 years old, Moore believes he knows what's behind the fears."Money. And the worst thing is, it's public money. You don't see people that are working for big industrial corporations coming out with this kind of garbage. They're trying to do something useful, right?...And these other people are parasites that are scaring us about something that is invisible."Moore's fascination with nature remains as his wonder at how life came to be."It is a miracle. I'm not a particularly religious person, but I am absolutely fascinated with what--we couldn't do this. We couldn't make life on Earth. We don't even know how it happened. And we may never know how it happened, how a bunch of dirt and air and water turned into life."
