The facts are, that the Arctic Sea ice extent measured by satellites since 1978 expresses annual variations and it has declined considerably from 1997 to 2007. However, before that time period, from 1978 to 1996, the downward trend was minimal, and in the last 17 years from 2007 to 2023 the downward trend has also been about zero. Therefore, there is no indication that we should expect the Arctic Sea summer ice to disappear completely, as predicted, in one or two decades.

These data shows that there is no apparent correlation between the variable extent of the Arctic and Antarctic Sea ice and the gradually increasing CO2-concentrations in the atmosphere, as proposed by NSIDC, IPCC and others.

Steve, I am never worried about C02, at least for now. Even our yearly corn crop eats more tons of it than trees though they all feast on it. It's plant food.

There would be danger if all plant life was exterminated though.

The shrill climate changers have never gotten anything right yet the worshipers, the hopefuls, still loyally follow and believe them.

I'm in complete agreement. I do feel that man may have some small affect on the planet. What that is, who knows.

The climate alarmists are creating this as their new religion.

How arrogant are we? We think we can change the climate of a planet? They claim "believe the science" but when the actual science of % of CO2 in the atmosphere, vs which is natural, they obfuscate and deflect the question.

I'll look for the data

So a brief search - .04% of our atmosphere is CO2. Plant-life requires at least .02% to survive. The alarmist want to reduce it by ~50%?

We can change cO2, because we have done it. Or is the change in CO2 over the last 150 years or so from 250 to 420 ppm from some other cause?

Yes plants benefit from CO2 , but high atmospheric CO2 levels affect the pH of rainfall. Thirty years ago there were strenuous efforts to limit nitrogen and sulphur dioxides as these gave us rain at pH 4 which killed off large tracts of forest and changed the ph of streams and lakes to the detriment of fish and algae. CO2 has a more limited effect on rainwater pH but there does seem to be evidence that it can change ocean pH.

More of the O2 we breath comes from oceanic algae than the Amazon. One type of Cyanobacteria alone produces 20% of global O2. How is the increasing atmospheric CO2 level going to affect oceanic algae? No one really knows. Is it worth trying to limit the amount we spew out to mitigate the risk? It’s not as simple as plants eat CO2 so more = better.

I wouldn't disagree that we should do what we can to limit our CO2 emissions.

However, we cannot limit our ability, as a country to compete in transportation, manufacturing or even our ability to defend ourselves.

Our competitors both economically and militarily abroad have not limited themselves. We all breath the same air. America is but a small part of the worlds CO2, but are the only one shooting ourselves to eliminate it.

There's some interesting stuff being looked into about the natural releases of CO2, and ways to possibly slow it or even stop it.
