all containers should get taxed in and out of ports, that would pay for everyone to own their won additive printer so we all make what we want at home.

Now the US is on board with IMO’s 2050 goal:

The opinion of shipping leaders around the world can be found in the latest Maritime CEO magazine:

Here is the opinion of one of them:

Others bet on wind power to reduce fuel consumption:

ships might be good but the land based power sources not so good

Relax, no one is going to deprive you of CO2. There is more than enough for everyone.

Yes CO2 is needed for plants and trees to grow, but not in large concentration and not in the upper atmosphere. (There aren’t any plants or trees up there)

If high concentration of CO2 is good for plants, why don’t they add some in greenhouses??

311

Well, actually they do


But otherwise you are correct.

My view is that there isn’t enough in the atmosphere yet. Yes! It’s that good. We need more.

313

It’s needed for all life everywhere.

The larger the concentration, the better is is for life.

You could always get the UN to ban this unseemly mixing of naturally occurring gases and allowing it to stray off the reservation.

They do. Lots of it. Look it up.

Get thee to an ophthalmologist who specializes in optorectumitis.

According to NOAA: " The global average atmospheric carbon dioxide in 2019 was 409.8 parts per million (ppm for short), with a range of uncertainty of plus or minus 0.1 ppm. Carbon dioxide levels today are higher than at any point in at least the past 800,000 years."

So what?

316

Because too much CO2 is not good for you.

To anyone with a modicum of intelligence that is a funny reply.

Oh I agree 
 but. Most greenhouses control CO2 to 1000-1200 ppm. Sounds good to me for the plants.

Typical levels in nuclear powered submarines are about 4000 and can go to 10000. Everyone here seems concerned for mariners conditions of service but none for submariners ‘suffering’ under these levels?

Current levels of CO2 are the equivalent of 40 cents in a thousand dollars and the panic merchants have you by the short and curlies.

And here’s an interesting article.

the planet was far greener back when it had a higher co2 content than today

Let’s hear it for Methane:

I’m sure Jughead will find something methane in the atmosphere is good for.
I believe there are some bugs that thrives on methane.(??)

Maybe Iceland could use some of the CO2 in the greenhouses where they grow their bananas??:
