I'm not sure your "facts" can be validated. There is naturally produced CO2 from lungs, volcanoes and all plant life, which gives off CO2 at night.

Then there's manmade CO2 from burning fossil fuels.

If one calculates CO2 in the atmosphere and that also absorbed by the oceans. Then CO2 levels are in uncharted territory.

Burning wood is sustainable as new wood replaces what we burn. At least it did. But we are using up our forests at more than a football field a day.

We know from the fossil record that at one time due to volcanic activity, that all life on earth was nearly destroyed! And we face a similar prospect if we sit on our hands or listen to dismissive right wing conservative ideologs like the Author.

Who think the sky will fall if we stop burning fossil fuels. Wrong, wrong, wrong! And demonstrably so! We can replace fossil fuels with nuclear power as perfected MSR thorium and with power prices as low or lower than 3 cents PKWH! Transport can be electrified.

And for portable fuel, we can use carbon neutral hydrogen. Breakthroughs in production have made the latter more than competitive with petrol, diesel and jet fuel.

We need to transition to the aforementioned ASAP and in so doing, create massive job and wealth creating opportunities and an economy on steroids/unprecedented economic growth!

Nothing to fear here but fear itself plus green and ultraconservative fearmongers.

When money and its pursuit becomes the only goal and more important than our wellbeing or survival, we get the asbestos, tobacco and fossil fuel industries lying through their teeth, just to maintain a profit curve and or share returns above all else, and logics rites.

I'm not too worried about CO2 levels in the time of the dinosaurs. They can solve their own problems. It's not that CO2 in human breath is good while coal burning is bad so much as one dwarfs the other, roughly 40 billion tonnes to 3 bn tonnes annually.

We're paying for climate change whatever technology prevails from now on. Worse than average blizzards in the US, heatwaves in Australia. The task now is to implement the least worst low carbon technology.

So "the amount humans breathe out is dwarfed by the amount produced by burning coal "... but..but what about the huge volumes of CO2 , sulphur and steam spewed out by volcanoes above and below the sea. All good according to the Green Dream Believers... And we won't mention the amount of "carbon" emitted by the thousands of delegates to the recent COP '23 and WEF Davos conferences where some of the dreaming turned into nightmares.

Look at what happened last year: A great interaction between the Antarctic atmosphere and surrounding regions, with large amounts of moisture bearing air moving over the continent via troughs, warming the air temperature substantially, and dropping large amounts of snow.

Later we had the revolting people at the ABC drooling at the prospect of Australia getting a fire and brimstone summer via an El Nino, presumably as punishment for voting no in the referendum or some such. The other day I hear a meteorologist telling us how we are are having a wet El Nino due to Antarctic interaction, an oxymoron if ever I have heard one.

Maybe this is another example of how the real world is a little more complicated than the computer model forecasts?

Human activity (not just breathing) emits 60X as much CO2 as active volcanoes per NOAA and 135X as much per USGS. A human produces about 1 kg CO2 per day but a flight from Australia to a northern hemisphere climate conference can produce about 3,000 kg CO2. Perhaps we need a population reduction to be able to afford climate conferences.

In my opinion recent turbocharged weather is straining our ability to cope. Example two floods and road washouts in the same area within a month. Why make it worse?

There is the effect of rock weathering as an absorber of CO2 to consider as well. More CO2 might mean more rainfall and more rock weathering, so the process might be self correcting.
