What about forest fires and volcanoes?
The CO
2 from forest fires would carry the Carbon-13 signature, it has been circulating in the atmosphere high enough to get
ZAPPED and gain a neutron ... say within the past million years or so ... still part of the natural 280 ppm ... and there have been volcanoes all along, so those would also be included in the natural 280 ppm and I don't think it's all that much ...
Not a trace of Carbon-13 in the remaining 125 ppm ... like the stuff has been buried for millions of years never reaching the upper atmosphere ... and that's why we're boiling the oceans off typing all this crap in ...
Pollution ...
I'm actually holding my breath so I don't pollute the atmosphere. I'm channeling James Nestor as we speak.
LOL do not worry, you will never set foot on a spacecraft or submarine, but you might find yourself in a cave collecting bat guano for your weed farm.
Yawn
LOL was I not supposed to mention the weed farm?
The quiet is deafening
Given your dire prediction concerning atmospheric CO2 pollution, I'd be surprised if I survived the night, Frannie.
When did I mention atmospheric CO2 pollution?
Oh yea I forgot, you have that delusional disorder thing
My bad
When you said CO2 was pollution, Francis.
Are you claiming that CO2 is not a pollutant that can cause a range of human effects culminating in death?
Exposure to carbon dioxide (CO2) poses direct risks to human health at lower levels than previously thought, research has found. Reviewing current studies on the subject, American academics concluded that exposure to ambient CO2 in indoor environments can have harmful…

The researchers cited mounting evidence that CO2 levels as low as 1,000ppm can cause health problems, even if people are only exposed to them for an hour or two.
They found that CO2 levels exceeding 1,000ppm have already been observed in crowded and poorly ventilated rooms such as classrooms, offices and bedrooms as well as air-conditioned public transport and planes – all places where humans can spend several hours at a time.
Collating the findings of numerous studies, the academics summarised that acute exposure to high CO2 levels can have ‘adverse health outcomes’, citing studies which observed inflammation and reduced cognitive performance above 1,000ppm.
Chronic exposure to levels between 2,000ppm and 3,000ppm can have even worse impacts as this was linked to effects including kidney calcification and bone demineralisation.
The team behind the study warned that human CO2 exposure may be a growing problem in the coming years as projections suggest that by 2100 outdoor CO2 levels in some cities could exceed 1,000ppm for parts of the year.
‘Continuous exposure to increased atmospheric CO2 could be an overlooked stressor of the modern and/or future environment,’ the study suggested.
The researchers concluded by saying further research is needed to find ways to mitigate exposure to indoor CO2, especially for children and vulnerable people, and to fully understand its potential health effects.
