CARBON SINK & CARBON SOURCES

New research, published in Nature Climate Change and available on Global Forest Watch, found that the world’s forests sequestered about twice as much carbon dioxide as they emitted between 2001 and 2019. In other words, forests provide a “carbon sink” that absorbs a net 7.9 billion metric tonnes of CO2 per year, 1.5 times more carbon than the United States emits annually. Unlike other sectors, where carbon makes a one-way trip to the atmosphere, forests act as a two-way highway, absorbing CO2 when standing, regrowing or releasing it.

Before now, scientists estimated these global “carbon fluxes” from the sum of country-reported data, creating a coarse picture of the role forests play in both carbon emissions and sequestration. With these new data that combine ground measurements with satellite observations, we can now quantify carbon fluxes consistently over any area, from small local forests to countries to entire continents. Using this more granular information, we found that the world’s forests emitted an average of 8.1 billion metric tonnes of carbon dioxide into the atmosphere each year due to deforestation and other disturbances, and absorbed 16 billion metric tonnes of CO2 per year.

This differs alarmingly from what our publicly funded CSIRO has claimed:

“Plants and soils take up 2.8 billion tonnes of this extra carbon, while the oceans take up 2.2 billion tonnes. The remaining 4.1 billion tonnes of CO2 stays in the air, increasing the atmospheric concentration of CO₂”.Humans generate CO₂ when burning fossil fuels such as gas, petrol, oil, and coal. This adds an additional 9.1 billion tonnes of CO₂ to the atmosphere each year. Plants and soils take up 2.8 billion tonnes of this extra carbon, while the oceans take up 2.2 billion tonnes. The remaining 4.1 billion tonnes of CO2 stays in the air, increasing the atmospheric concentration of CO₂.

THIS NOT TRUE. Even the IPCC indicate a minimum CO2 residence of 5 years. Revelle said a maximum 10 years  Revelle and Seuss

Stallinga (2023) compiled a list of 36 published estimates of CO2 residence time spanning the decades 1957-1992. All of these scientists determined CO2’s atmospheric residence time is about 5 to 10 years or less.

Of course, these were the pre-IPCC decades in climate research, when “the science” was pursued independent of government interference. For example, it was still acceptable in the 1950s to early 1990s for scientists to publish actual ice core measurements showing the atmospheric CO2 content ranged up to 700 ppm, even 2,450 ppm, in the ice sheets and glaciers examined throughout the last 10,000 years (Jaworowski et al., 1992).

An actual residence time that is 20 to 40 times shorter in duration than what an AGW modeled thought experiments allow undermines the dangerous greenhouse gas accumulation talking points, as “if the residence time is below 30 years, injections of CO2 in the atmosphere would, just as water, not affect the climate” (Stallinga, 2023).

In addition to compiling an exhaustive list of past estimates supporting a 5-10 year residence time, Dr. Stallinga cites the evidence from atomic bomb tests, the lack of any atmospheric CO2 effect from the pandemic lockdowns and associated sharp drop in  emissions, and the lead-lag relationship CO2 emission has with temperature as evidence supporting the once commonly-accepted conclusion that CO2 residence is closer to 5 years, not centuries. And if residence time is only 5 years, nearly “90% of all anthropogenic carbon dioxide has already been removed from the atmosphere.”

    Some of these warming enthusiasts don’t know that before the 1950’s, that people living in the country, wood was our main source of energy. It was used for heating, cooking, hot water services (if we were lucky) and Laundry. I can remember making my Mother a laundry stick to assist with the lifting of clothes out of the copper.
