@1patriot The reduction in CO2 levels since the Cambrian period can be attributed to several processes:

Dissolving in the Oceans: As the oceans formed, carbon dioxide dissolved to form soluble carbonate compounds, so its amount in the atmosphere decreased.

Use by Plants for Photosynthesis: Plants use carbon dioxide for photosynthesis, which also contributed to the decrease in CO2 levels.

Formation of Fossil Fuels: When plants died, their carbon compounds became locked up underground, forming fossil fuels

@Heraclitus right on all accounts....do you believe the planet is being warmed by CO2?

@1patriot Along with other greenhouse gases, such as methane, which is the most potent of the greenhouse gases, yes. I am not a science denier, so why wouldn't I? And the warming of the planet includes the warming of the oceans. Most of the increased warming has been absorbed by the oceans. In fact, about 90% of global warming is absorbed by the oceans. This absorption of heat has been happening since modern recordkeeping began in 1955. The top few meters of the ocean store as much heat as Earth’s entire atmosphere. The effects of ocean warming include sea level rise due to thermal expansion, coral bleaching, accelerated melting of Earth’s major ice sheets, intensified hurricanes, and changes in ocean health and biochemistry. It’s important to note that the ocean’s ability to absorb heat plays a crucial role in balancing the excess heat from rising global temperature.

Greenhouse Effect: CO2 and other greenhouse gases trap some of the heat that Earth might have otherwise radiated out into space. When sunlight reaches Earth, the surface absorbs some of the light’s energy and reradiates it as infrared waves, which we feel as heat. These infrared waves travel up into the atmosphere and will escape back into space if unimpeded1. However, CO2 absorbs energy at a variety of wavelengths that overlap with that of infrared energy. As CO2 soaks up this infrared energy, it vibrates and re-emits the infrared energy back in all directions1. About half of that energy goes out into space, and about half of it returns to Earth as heat, contributing to the ‘greenhouse effect’.

Human Activities: Each year, human activities release more carbon dioxide into the atmosphere than natural processes can remove, causing the amount of carbon dioxide in the atmosphere to increase. The annual rate of increase in atmospheric carbon dioxide over the past 60 years is about 100 times faster than previous natural increases. Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy. Human activities have raised the atmosphere’s carbon dioxide content by 50% in less than 200 years, causing the earth’s temperature to rise.

Water Vapor Feedback: As carbon dioxide and other greenhouse gases heat up the planet, more water evaporates into the atmosphere, which in turn raises the temperature further.

In summary, the increase in CO2 in the atmosphere, primarily due to human activities, traps more heat, leading to global warming and climate change.

@Heraclitus yes Sarah DeLisle Fecht is the Executive Director of Vanderbilt Programs for Talented Youth. Sarah joined PTY in 2012 after teaching in Metro Nashville Public Schools. one of your paid globalist that write for Columbia Climate School. you realize they have to make sure we all fall for there climate scare that's why they are spending billions if not trillions. that's the only way they will get the mandate to control your government and install CBDC.

the only thing that warms this planet is the sun....she trying to sell you a bullshit story. don't fall for it! [friendsofscience.org]

@1patriot Of course the only thing that warms the planet is the sun. Greenhouse gases do not warm the planet, they retain heat. What do you think climate change and global warming is about?

@Heraclitus Sarah DeLisle Fecht is the Executive Director of Vanderbilt Programs for Talented Youth read her article if you want know how they lie.... i read 3 weeks ago i can't remember the shit she saying but it the same garbage all the climate alarmist jabber about coal exhaust and vehicle exhaust well they fly million planes around the globe per day. but you and i are the problem. sponsored by Vanderbilt the billionaires. and that's what you posted to me.....CO2 doesn't retain the heat either. it cools ever night we are out of the sun. you might have some cloud cover come in sometimes and the does not escape but that is natural they have to get all the dummies to believe the planet is warming and you need to stop using fuel you only have 10 years to live....do you really believe that shit!!!! electrical vehicles are joke don't buy one

@1patriot Well, at least I got the name Sarah DeLisle Fecht out of you. Her articles says that it is possible to limit global warming to 1.5 degrees. So what? It has none of the paranoia that you claim.

You are talking absolute nonsense. Who convinced you of this paranoia nonsense and why did you believe it? EVERYONE who talks about climate change talks about coal exhaust and vehicle exhaust being a large part of the problem...the opposite of what you are saying. Of course, the air cools down at night regardless of CO2. Every five-year-old knows that and it has NOTHING to do with climate change. NO ONE who talks about climate change claims we have only 10 years to live. No, it is not simply about buying an EV, and I don't own one. So, you are a paranoid who thinks climate change is just a Vanderbilt hoax?? Who told you that B.S. and why did you believe it? Why do you let people make a fool out of you?

Whether you are a complete fool who has been victimized by the silly B.S you have been fed, a paranoid-schizophrenic, a troll who does this for a warped sense of fun, or a planted bot, I cannot really tell, but you obviously are someone who must be blocked.
