Climate Change

I have taken this from somewhere else. I have not checked the accuracy.
The Atmospheric CO2 levels in 1850 (beginning of the Industrial Revolution and the green ideological start point) was 280ppm (parts per million atmospheric content) (Vostok Ice Core).
Atmospheric CO2 level in 2021 was 410ppm. (Mauna Loa)
So lets show the growth per year. 410ppm minus 280ppm = 130ppm ÷ 171 years ( i.e. 2021 minus 1850) = 0.76ppm. Man is responsible for 3% of that which is 0.02ppm.
That’s every human on the planet and every industrial process adding 0.02ppm CO2 to the atmosphere per year on average between those years. At that rate mankind’s CO2 contribution would take 25,000 years to double which, as the IPCC states, would cause around 2°C of temperature rise. That’s 0.0001°C increase per year for 25,000 years.
If the above is fact checked, are we really experiencing a climate crisis?

Interesting logic......how many people were around in 1850, compared to now? Surely you're not a climate change denier, Christel.
I skied around Europe back in the day, and it was clear to me that a change was taking place at an increasing rate.
Great years with plenty of snow when I started.....then the occasional poor year and the need to go higher, then a few years later, snow cannons started appearing.
The jury is out as to whether climate change is entirely down to the sheer weight of humans now ripping the guts out of the planet, but it can't be helping...

Have a look at Nature Bats Last on You tube. Dr McPhearson is advising us that we are past the 'tipping point' and are in the middle of the sixth 'Great Extiction Event'.
I make no comment ofn the accuracy of his prediction.
BTW Methane and Water Vapour are worse for Global Warming than CO2

Pete, big difference between a climate denier and critical thinking of the world having a climate crisis.
I completely agree that the climate is changing, question is what is the cause?
Not that important how many people were around in 1850, as we are looking at CO2 ppm measured at the years in question.
Are we humans to blame or is it a natural development over many years? Looking at the numbers I quoted it looks like humans and their activities are not the big cause?

Also the fact that there are more and more people on this planet seems alarming however the prediction is that the upward trend will turn dramatically. Mainly because us white women in developed countries are having less and less children.

In my lifetime there has been predictions of ice ages and now global warming, no doubt in the remainder of my life scientists/governments will come out with something new so they can preach and tax us on.

Preach and tax...yeah, there is something there, however who benefits?

Where does the mankind 3% figure come from?

Would be nice if someone could explain that 3% indeed?

Slightly on topic…..I love James Lovelock’s reply to the question “what should people do about global warming ?”
“Buy a shotgun!”
