Yes, I assert that there is no connection whatsoever between CO2 and climate change. That's all a crock of crap, in my opinion.

CO2 is an odorless, invisible, and non-flammable gas. It is also safe for humans in the maximum concentrations recommended for plant growth. The average level of CO2 in the atmosphere is about 390 PPM (parts per million). If the level decreases down below 200 PPM in an enclosed growing area, plant growth slows to a halt. Through the years of testing and research, the optimum enrichment level of CO2 for plant growth has been agreed to be about 1500 PPM. With CO2 enrichment, under good conditions, plant growth rates and flowering will increase 20-100%. CO2 can be used from seedling right through harvest. It may take a hundred years for CO2 to get up to 1500 PPM. During that time, plant growth will flourish.

Developing countries with fossil fuels are very clear that when push comes to shove, they will always prioritise development over emissions reduction. So if we want to deliver the Paris Agreement, helping them use fossil fuels more cleanly is the only game in town.

Our planet and humankind have been challenged by climate change and extreme weather throughout history. The sun’s changing energy output and other natural forces have brought little ice ages, floods, droughts, powerful storms, and periods of prolonged warmth and bounteous harvests.

To assert that natural forces no longer play a role, that fossil fuel emissions now control climate change, or that humans can now determine planetary temperatures and climate by regulating atmospheric carbon-dioxide levels is sheer hubris. To say we should abandon the hydrocarbon energy that has brought technology, prosperity, health and longevity to billions is sheer insanity.

I’m typically sceptical about proposals for massive, widespread deployment of wind and solar power. My problem with the idea is that these sources are intermittent, meaning we need to maintain 100 per cent backup power that we don’t intend to run much of the time, in the absence of better storage.

global climate has always changed and always will, independent of the actions of humans, and that carbon dioxide (CO2) is not a pollutant but rather a necessity for all life.

global warming is not a global crisis.

William JR Alexander was a signatory to the 2007 open letter to the Secretary-General of the United Nations preceding the UN climate conference in Bali.

The letter describes CO2 as a “non-polluting gas” and suggests that reducing greenhouse gas emissions will not prevent global warming.

In the last 5-10 years, we have heard ad nauseam that there is a scientific consensus— that anthropogenic global warming is real, that man is causing the earth to warm at an alarming rate by the burning of fossils fuels, that we are nearing a tipping point after which we are doomed. That consensus arose out of the UN’s IPPC group of 2500. However, in that group there are only about 300 qualified scientists. At the same time, dissenting groups of scientists numbering 100’s to 1000’s, and in one case, 10s of 1000s have disagreed.”

For half a century, greens have been prognosticating the imminent collapse of society. Yet with each new generation, deadlines to stop the destruction of the planet pass without event. In reality, the world’s population has become healthier and wealthier, and we live longer lives than ever before. Panic about the virus achieved in days what greens have been demanding for years: grounded planes, empty roads, and a halt in economic growth.

I am positively convinced that the anthropogenic global warming theory is wrong. New developments in the physics of greenhouse effect and radiative transfer show that the accepted theory leads to largely exaggerated global warming projections.

It is hard to advocate for overbearing regulations that attempt to reduce energy use and greenhouse gas emissions when global temperatures have been stable or declining. In fact, in at least the last seven years, global temperatures have declined, despite increases in atmospheric carbon dioxide,” Wynn wrote.

I'm a skeptic. ...Global Warming it's become a new religion. You're not supposed to be against Global Warming. You have basically no choice. And I tell you how many scientists support that. But the number of scientists is not important. The only thing that's important is if the scientists are correct; that's the important part.

Please remain calm. The earth will heal itself. Climate is beyond our power to control. The earth doesn't care about government and legislation. Climate change is a matter of geologic time, something the earth does on its own without asking anyone's permission or explaining itself.

It is possible … we have unwittingly begun a massive experiment with the system of this climate itself,

This would require more, not less, government “for energy production, for fuel efficiency, for reforestation,”

It’s not a hoax, but it’s not proven science either...

But you don’t dismantle America’s power and energy on a maybe. We need to be energy independent first. We need to do it better, which we can, but it is not a settled science.

The report clearly shows that the technologies assumed to populate the clean energy shift—wind, solar, hydrogen, and electricity systems—are in fact significantly MORE material intensive in their composition than current traditional fossil-fuel-based energy supply systems.
