Jim, here's another thing for you to consider. Something unrelated yet corroborating with what's going on with the environment, the health of this planet.
It took all of human history from the dawn of the human age to 1800, for the human population to reach one billion.
124 years after that, to reach 2 billion.
33 years to reach 3 billion.
15 years to reach 4.
12 years to reach 5.
Another 12 years to reach 6.
And we are projected to reach 8 billion by 2024.
This coincides with the industrial revolution, and also with the spiking of the amount of carbon found, trapped in ice, in Antartica.
Do you not think that a difference of 7 billion people inhabiting this planet in the mere course of 200 years, has altered the ecosystem of this planet?
Yes that makes sense IMO. However, I have never really thought about it and have no way to quantify how many people are too many.
Regarding Antarctic ice cores and their CO2 levels: keep in mind that any ice core in the Antarctic is going to have much lower CO2 levels than say at the equator, or in the Greenland ice sheet. This is because CO2 tends to concentrate in much higher levels from around the equator to the extreme northern hemisphere. So an Antarctic ice core CO2 level of 300ppmv may actually indicate much higher concentrations of CO2 elsewhere in the atmosphere at the same time. If you wish to be as accurate as possible I would focus on northern hemisphere ice cores vice Antarctic. They don’t go back as far, but they go back far enough.
Impressive Jim.
And speaking of the IPCC, they happen to be in the news themselves today.....
"Saudi Arabia has successfully lobbied for a major climate change report to be scrubbed from international negotiations on limiting global temperature rise to 1.5C.
The Saudis led a loose coalition of oil-producing nations, including the US, Russia and Iran, that objected to the science behind the UN’s Intergovernmental Panel on Climate Change (IPCC).
The report emphasized the need to keep warming down to 1.5C as a matter of survival for many countries and called for drastic action to reach this goal, with the whole world needing to hit zero emissions by 2050.
However, as a result of the Saudi-led intervention, this landmark report was blocked from formal climate talks at Bonn this week. This will substantially weaken its influence on future policy.
The final UN report had just five watered-down paragraphs on IPCC findings, explaining that they were based on the “best science available” without including more concrete information on how countries should reduce emissions targets. "

I’m not surprised. One of the best physics prof’s I ever had said that at some point, all this alarmism would settle down and politicians would move on to some other bugaboo. One might think that we are inevitably headed to destruction if that happens. I don’t. There’s too much potential to make money (patents, technologies etc.) and we’re going to see things coming online in the next 50 years that will make any concerns we have today seem rather ignorant and short-sighted…that’s the way it goes
