The carbon cycle operates in equilibrium with relatively slow changes over time unless there is a super volcano or maybe an asteroid. So the carbon cycle absorbs and releases carbon so sinks like Canada's forests, soils and wetlands absorb and release carbon in a continuous cycle.
In the last 200 years humans have altered the landscapes with deforestation, drained wetlands, adopted intensive agriculture and dumped trillions of tons of CO2 into the atmosphere from fossil fuels. If sinks were absorbing all the fossil sources of carbon on a global scale, then CO2 levels in the global atmosphere would not be rising. And Canada's sinks are not likely capturing significantly more carbon than they are releasing in the carbon cycle.
Carbon dioxide now more than 50% higher than pre-industrial levels
https://www.noaa.gov/news-release/carbon-dioxide-now-more-than-50-higher-than-pre-industrial-levels
"Prior to the Industrial Revolution, CO2 levels were consistently around 280 ppm for almost 6,000 years of human civilization. Since then, humans have generated an estimated 1.5 trillion tons of CO2 pollution, much of which will continue to warm the atmosphere for thousands of years.
CO2 levels are now comparable to the Pliocene Climatic Optimum, between 4.1 and 4.5 million years ago, when they were close to, or above 400 ppm. During that time, sea levels were between 5 and 25 meters higher than today, high enough to drown many of the world’s largest modern cities. Temperatures then averaged 7 degrees Fahrenheit higher than in pre-industrial times, and studies indicate that large forests occupied today’s Arctic tundra."Last edited by chuckChuck; Oct 23, 2022, 07:55.

Yet today we call it climate armageddon?
Do you know what optimum means?

Go green or die!
That describes what a significant portion of the population now believe.
Our Prime Minister may fit the profile?

Whereas anyone else who possesses any shred of self dignity would shrink back under the rock they crawled out of, after being exposed as a completely uninformed hypocrite at every opportunity.
But not our chuckchuck, he's always eager come back and keep digging the hole deeper.Last edited by AlbertaFarmer5; Oct 22, 2022, 14:42.
