i do apologize Marum, i've given you way more credit than is due.
your posts sound a bit science-y but the reality is you're just shooting from the hip, confecting word salad as you go along and seeing how it goes down.
basically, if not clueless, certainly a long way towards it. Such as the garbage about the impact of volcanoes and your fiction above about "any climate change would (have) vanished."
certainly climate change deniers are "up themselves" rarely referencing their self-important statements to any credible source. Mounting arguments that can fairly be described as puerile.
Deluding themselves that Because They Said So then it must be right. Wrong, just file under onanism.
this is from a page climate.nasa.gov. It's worth if you wanted to learn something about what you're claiming.
"The Atmosphere: Getting a Handle on Carbon Dioxide Sizing Up Humanity's Impacts on Earth's Changing Atmosphere: A Five-Part Series By Alan Buis, NASA's Jet Propulsion Laboratory"
"Changes to our atmosphere associated with reactive gases (gases that undergo chemical reactions) like ozone and ozone-forming chemicals like nitrous oxides, are relatively short-lived. Carbon dioxide is a different animal, however. Once it’s added to the atmosphere, it hangs around, for a long time: between 300 to 1,000 years.
" Thus, as humans change the atmosphere by emitting carbon dioxide, those changes will endure on the timescale of many human lives.
"Earth’s atmosphere is associated with many types of cycles, such as the carbon cycle and the water cycle. Crisp says that while our atmosphere is very stable, those cycles aren’t.
".“Humanity’s ability to thrive depends on these other planetary cycles and processes working the way they now do,” he said. “Thanks to detailed observations of our planet from space, we’ve seen some changes over the last 30 years that are quite alarming: changes in precipitation patterns, in where and how plants grow, in sea and land ice, in entire ecosystems like tropical rain forests. These changes should attract our attention.
""One could say that because the atmosphere is so thin, the activity of 7.7 billion humans can actually make significant changes to the entire system,” he added. “The composition of Earth’s atmosphere has most certainly been altered. Half of the increase in atmospheric carbon dioxide concentrations in the last 300 years has occurred since 1980, and one quarter of it since 2000. Methane concentrations have increased 2.5 times since the start of the Industrial Age, with almost all of that occurring since 1980. So changes are coming faster, and they’re becoming more significant.
""The concentration of carbon dioxide in Earth’s atmosphere is currently at nearly 412 parts per million (ppm) and rising. This represents a 47 percent increase since the beginning of the Industrial Age, when the concentration was near 280 ppm, and an 11 percent increase since 2000, when it was near 370 ppm.
"Crisp points out that scientists know the increases in carbon dioxide are caused primarily by human activities because carbon produced by burning fossil fuels has a different ratio of heavy-to-light carbon atoms, so it leaves a distinct “fingerprint” that instruments can measure. A relative decline in the amount of heavy carbon-13 isotopes in the atmosphere points to fossil fuel sources. Burning fossil fuels also depletes oxygen and lowers the ratio of oxygen to nitrogen in the atmosphere."
