It still shows that there is less Co2 than in previous times and possibly reach a critical level of low Co2.

"Wheat grain protein has also been found to decrease by 7.4% under elevated CO2 due to reductions in threonine, valine, iso-leucine, leucine, and phenylalanine. The mineral nutrient contents in grains of rice and maize were similarly found to decrease under high CO2 by 1.0% and 7.1% for phosphorus, 7.8% and 2.1% for sulfur, 5.2% and 5.8% for iron, 3.3% and 5.2% for zinc, 10.6% and 9.9% for copper, and 7.5% and 4.2% for manganese, respectively. In general, mineral concentrations in C3 plants are predicted to decrease by 8% under elevated CO2, while total non-structural carbohydrates (mainly starch and sugars) are expected to increase. These decreases in grain protein, amino acids, and mineral nutrients could double the incidence of global protein-calorie malnutrition and micronutrient deficiency—especially in Africa, where agricultural soils are inherently low in nutrient elements. Additionally, the increase in total non-structural carbohydrates (mainly starch and sugars) in cereal crops could elevate diabetes incidence due to heavy reliance on starchy diets. The negative effects of elevated CO2 on rice, maize, and wheat—the world’s three major staple crops—suggest an increase in global food insecurity with rising atmospheric CO2 concentration."

It's not all bad news, many worst case predictions are now being revised as the effects of sustainable electrical generation etc begin to take effect. But climate tipping points are somewhat unpredictable so it would be wise not to take further action to minimise the effects we are having.

I think that those who want to restrict others should lead by example. In the case of climate, that means all those politicians pushing this should be getting rid of their cars, only cycling, walking, using public transport or carpooling, only buying locally produced food and only in season, using clothing only from natural fibres through sustainable sources, reusing and recycling all their own waste, not using or buying anything with single use plastic, only using renewable energy, not flying anywhere, not using AI, and certainly not taking private flights or helicopters, and not travelling around the world on holiday. If they're going to talk the talk, they need to walk the walk. If not, then they're hypocrites and should not be humoured.

I doubt it would reach anywhere near a dangerous level, all the previous low levels seem to have been linked to ice ages. CO2 levels have fluctuated quite a bit, often about half of what we have now.

So basically, there isn't too much Co2, it's all scaremongering

Plus your graph is taken from the CO2 Coalition, take a bit of time to research them, they are pretty outlying, right wing conspiracy theorists with pretty much no scientific basis for their views, going extremely against consensus (which admittedly is not always correct and should be questioned).

CO2 Coalition - Wikipedia

CO₂ Coalition - Bias and Credibility

QUESTIONABLE SOURCE A questionable source exhibits one or more of the following: extreme bias, consistent promotion of propaganda/conspiracies, poor or no

mediabiasfactcheck.com

QUESTIONABLE SOURCE​

A questionable source exhibits one or more of the following: extreme bias, consistent promotion of propaganda/conspiracies, poor or no sourcing to credible information, a complete lack of transparency, and/or is fake news. Fake News is the deliberate attempt to publish hoaxes and/or disinformation for profit or influence (Learn More). Sources listed in the Questionable Category may be untrustworthy and should be fact-checked on a per-article basis. Please note sources on this list are not considered fake news unless specifically written in the reasoning section for that source. See all Questionable sources.

• Overall, we rate the CO₂ Coalition as right-biased and questionable due to its consistent promotion of climate change skepticism, lack of transparency around funding, selective presentation of data, rejection of the scientific consensus on anthropogenic global warming, and several certified failed fact checks.

Where did you find that graph?

In a research paper, can't remember which university off hand

Seriously, they have about as much credibility as flat Earthers

Where will people live if the sea keeps rising?

Funnily enough old photos and engravings are evidence that the Needles on the Isle of Wight are rising along with sea level.

Your link in post 44 seems to agree with the Co2 coalitions graphs and the quote that today's Co2 levels " are nothing special " backs this up.

That sounds a hard place to live

Nothing special at all in the Earth's geological history, however, the rapidity of the change and the likely effects are not very conducive to human civilisations dependent on predictable crops.

Most on here do give a dam
That’s why we are very sceptical look into the financial records of the big green companies ceo & the likes
Old saying follow the money

Follow the temperature. It’s a better gauge of what is happening.
Forget who is at play and all of the conspiracy theories, just look at the raw data and your eyes will not lie to you.
I promise

And that is the crux of the issue. The carbon has been locked away for millions of years and we are rapidly releasing it.

The laws of thermodynamics are simple in that matter cannot be created, only converted from one form to another. That is what we are doing - turning carbon that was once trees and sea critters into coal, oil and gas and then back into co2 (which creates a greenhouse effect on the planet).

This is not a problem if we have plenty of trees to suck it back up again and lock it away, but we have also cut the forests down!

All of this has been known and predicted for decades and yet people still say it’s all fake, despite countless scientific studies proving the case for man made climate change. But, some people cannot be told and will always take the easy option.

But when agriculture in the uk collapses or our deer species die out because we have very dry summers or very wet winters then I guess people might give a damn!!

It doesn't matter how many trees you plant, the co2 that they sequester originates at ground level as part of the neutral carbon cycle, the upper atmosphere stuff comes straight of the exhausts of jet aircraft, if the policians are serious about it there needs to be an immediate phase out of carbon based aviation fuels, but they aren't.

And the answer is, drum roll....taxation, taxation, taxation....err no.

That graph says never been higher, but if you go back further in time it has by a lot, nothing like using partial data to suit your own agenda.
