Reply to During the mid-Cretaceous approximately 94.5 million years ago the worlds oceans became nearly uninhabitable as rapid degassing of volcanic carbon dioxide altered seawater carbonate chemistry, triggering a global-scale episode of reduced marine oxygen levels known as Oceanic Anoxic Event 2. by avogadros_number

Invisible is the correct scientific term for when you can see something but not process the information.

So yes it is invisible. "Not perceptible by vision"

Your understanding of what that word means scientifically is what is wrong.

Go back to reading comic books and fiction and stop making up incorrect meanings for words.

When we talk about individual action, we aren't talking about recycling.

Corporations can't magically find a "green" way to manufacture all the creature comforts we demand to consume, because the very products themselves are carbon-intensive. The only way to realistically make a difference is to curtail most industrial manufacturing, which DOES imply that ordinary people are going to have to make cutbacks and change their lives.

Here is a list of things that BOTH corporations AND individuals need to eliminate in order to have a shot at fighting climate change:

Personal vehicles, air travel, air conditioning, meat and animal products, single family homes, and electronics. Does it sound extreme? Sure, but these are extreme times. We ignored the warnings for decades.

Normal parlance is based off of fiction and fantasy and super heroes has no bearing on scientific meaning.

Invisible is 100% the correct term according to science.

"Not perceptible by vision"

A Hunter standing in front of his prey is considered "invisible" if the prey is not able to process what is about to occur and not because he is bending light around his being.

If it was up to redditors. Only governments and their coordinated action can make impact. My wife picks up garbage on the road sides, we recycle and drive 1-2 times a week. So what? Unless producers change how they manufacture goods, ranchers feed cows those seaweed supplements, carbon capture facilities are built, energy production is green — there will be no impact.

Do you seriously think that a small fraction of the population who posts on reddit can make that change?

Climate change is like a war. Individuals can’t win it. You need governments (plural) to regulate the industry and rebuild the economy. No private company, like Tesla or Bill Gates’ initiatives will do the job.

Reddit audience is unfortunately not representative of the US population.

Invisible is the correct term and just means "not perceptible by vision".

Your Amygdala is perceiving the "fear" and aware of the visual stimulus and receiving and relaying information even if your conscious is not aware and the image is not being processed by your visual cortex, so technically imperceptible would be incorrect unless you specify imperceptible by vision which is literally the scientific meaning of "Invisible"
