Chuck explain?

That is fine if plants have moisture to go with the CO2.

Even better news. increased CO2 also significantly reduces plants ( except C4 plants) water needs, making them much more drought tolerant. You don't even need to increase the moisture to see the benefits of increased CO2. You could even decrease it and still see large benefits.

Miraculous little molecule.

Ottawa announces $100,000,000 to Montreal for 100 jobs. Yep $1,000,000 per job building car batteries. Tax incentives are grants to oil industry but direct-deposit to green BS is not a subsidy?

Very nice cut and paste chuck.

Why are our levels right now the lowest level since the great ice age yet it’s a problem now.

They are not at the lowest level since the last ice age or in the history of the world as you claim. In fact they are more than double the concentration at their low point of the last glaciation period. And they are more than 1/3 higher than the highest concentration reached over the last 7 glaciation periods.

The last time glaciers covered North America (ending about 11,000 years ago) ice core samples in Antarctica showed CO2 concentrations in the atmosphere at 180ppm. The highest CO2 levels reached before 1950 and in the last 800,000 years (again based on ice core data) in which time there were repeated glaciations on earth was 300ppm. Today the CO2 concentration is about 415 ppm.

So if your chart is true we should be warming at such a rate and rain events would be more as we become the tropics.

But it’s not.

Also why only play with number for the last 50 years and not look at the big picture.

The chart I posted is only about CO2 concentrations and extends not for just 50 years but 800,000 years and disproves you claims about current CO2 levels. Nor is the chart or am I making any claims about the correlation of CO2 levels and temperature or precipitation, it only addresses CO2 levels. The only question that this chart should bring up is what has happened in the last century and a half which has changed the cycle of CO2 concentrations that has been relatively stable over the last 800,000 years.

If you looked at the initial chart you would see it goes back much farther than 800000 years.

They love picking and choosing to fit the narrative. Sad science can prove back millions of years they don’t look at that.

So what? SF3 claimed we are at the lowest point in the history of the world for CO2 and I presented data showing it is the highest it has been in 800,000 years by actual measurements. I could have provided this to refute his claim: "Widespread forests slowly draw in massive amounts of CO2, gradually lowering the level of atmospheric CO2 from 650 ppmv down to around 100 ppmv during the Miocene." (23 million years ago) https://en.wikipedia.org/wiki/Geologic_time_scale#:~:text=The%20geologic%20time% 20scale%20(%20GTS)%20is%20a,timing%20and%20relatio nships%20of%20events%20in%20geologic%20history. https://en.wikipedia.org/wiki/Geologic_time_scale#:~:text=The%20geologic%20time% 20scale%20(%20GTS)%20is%20a,timing%20and%20relatio nships%20of%20events%20in%20geologic%20history.
The Miocene epoch marked a CO2 level 1/4 of today's level but it it irrelevant comparison because there were no humans around then - homo sapiens first appeared around 800,000 years ago. Land masses were different back then too because of continental drift so ocean currents were different. There was a time when the earth was molten, no oxygen, and more methane as the atmosphere too. Again so what?

I ask you too why for the entire period humanoids walked the earth has CO2 levels been consistantly cyclical and never exceeding 300ppm until a century and a half ago. What and why the change that has boosted CO2 levels by 1/3 higher than seen in 800,000 years?

That’s not the history of the world that can be proven

you are the one who picked the time period before man even existed to claim make your claim CO2 levels are at the lowest in history. Why did you pick prehistorical levels for comparison instead of any period in the last 800,000 years? Seems like you are the one picking and choosing to try to fit you narrative but unfortunately, real data does not even support your claim.

YOur right, the only actual measurements we have for CO2 are from the last 800,000 years through ice coring in Antarctica yet and all that data disproves your point that we are at the low point in CO2 concentrations.

[SASKFARMER]

Oh now you can’t use before-man existed it is bad.

It’s the history and cab be proven by science not pick and choose
