We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

Supposedly the new stringent heavy shipping emissions controls are having an impact on the greenhouse effect. Reduction of sulfur dioxide which had a reverse greenhouse effect is warming the oceans up more.

"Carbon Brief analysis shows that the likely side-effect of the 2020 regulations to cut air pollution from shipping is to increase global temperatures by around 0.05C by 2050. This is equivalent to approximately two additional years of emissions."

So this may be our first example of the threats of NOT enacting terraforming for climate change will have.

It proves that creating cloud cover will impact ocean temperature. There are methods of doing this without creating acid rain. Just spray ocean water as a fine mist into the air and you should get some nice fluffy clouds. We have the capability to cover entire oceans in cloud cover to mitigate global warming.

Obviously this would have some unpredictable impacts on weather patterns, but we're already dealing with that no matter what we do. We're at a point where we're desperate enough to try some crazy schemes like this.

Ah so we’re entering the scorched sky time line of the apocalypse.

After September 11th and the COVID lockdowns, scientists noted an increase in global surface temperature due to the absence of contrails. So yes, this is actually something we are already doing!

Sulfur dioxide however is an even more effective reflector of sunlight compared to water vapor. And don't forget, water vapor is itself a very greenhouse agent that contributes toward planetary heating.

Hank Green had a pretty decent video in this.

We can do the same thing without the horrible pollution that ships produced.
