From response by James Matkin  Former Deputy Minister at Government of British Columbia to Quora question What are the criticisms of the Canadian federal carbon pricing system implemented under the Trudeau government’s “Pan-Canadian Framework” on climate change?  Excerpts in italics with my bolds.

The big lie is that Canada needs more carbon dioxide, not less, which is the intent of the carbon tax. Also, there is no carbon pricing system; rather, there is a carbon dioxide pricing system. Carbon is not the equivalent of CO2.

We need less carbon pollution from coal and more
carbon dioxide for our health and well-being.

This mistaken terminology deceives the public as it portends pollution. Amazingly, US President Obama, Trudeau, and Kamala Harris falsely call CO2 carbon pollution.

CO2 is used to save premature babies in incubators.

CO2 is the primary gas for fire extinguishers.

The solid form of CO2 is dry ice not carbon.
Likewise the solid form of H2O is ice not hydrogen.

More CO2 has enormous benefits for crops and our health. It also greens deserts and saves fresh water by spurring tree growth.

If CO2 was a problem why does the commercial greenhouse industry infuse up to 1500 ppm 7/24 to increase plant growth?

Canadians pay an imposing Carbon Tax to save the planet, while the rest of North America has no such Carbon Tax. If you look at economics, the Carbon Tax lowered our standard of living and did nothing for Climate Change.

Canada is a foolish outlier that punishes citizens with a carbon tax to harm plant growth, hospital surgeries, and water retention and cause inflation making the poor poorer.

Canadian emissions of CO2 by fossil fuels are only < 5% of natural
CO2 sources which are too tiny to matter if CO2 mattered to the climate, which it doesn’t.

The driving forces of climate change are natural
not human emissions of CO2

The UN claim that human industry Co2 emissions are causing runaway global warming that will end in catastrophe if not arrested with renewables and carbon taxes was only a thought experiment without any physical observation. Think about this – the UN said there was no historical precedent for the rapid rise in temperatures after industrialization therefore increased CO2 must be the culprit. This is both false logic and untrue. A raft of studies about temperature variability from ocean currents or changes in solar cycles evident in rising or falling sunspots easily explains the temperature rise.

Today with the benefit of hindsight there never was any fast rising temperatures needing explanation. In fact temperature’s rise of less than 1 °C over the past 140 years and now falling 0.4 °C in the past three years means no global warming now or in the past.

Because the climate changes over a long period of time no one living or dead has actually looked out the window and observed climate change. You see weather and it may be a heat wave, snow storm or record rainfall, but one weather event is never a new pattern of changing weather because that must be a statistical analysis.
