CO2, a greenhouse gas, doesn't warm the planet?
Surely you can see how absurd your response sounds.
It doesn’t cause, and cannot cause, catastrophic global warming .
I would recommend learning the basics before trying to hold this conversation.
Meet the Greenhouse Gases!
CO2 prevents some of the sun's infrared energy, which produces heat, from returning to space.
The more CO2 in the atmosphere, the more energy and heat retained in the atmosphere. And CO2 can last in our atmosphere for hundreds of years, so it gradually adds up over time as we emit it.
It's that simple.
Of the amount of CO2 that naturally occurs from volcanos and the oceans, which we have no control over, our percentage of CO2 output is minuscule.
We emit at least an average of an order of magnitude greater CO2 than volcanoes emit, each year. Meaning that volcanoes CO2 output is actually miniscule in comparison to ours. You have it backwards.
Are Volcanoes or Humans Harder on the Atmosphere?
"According to the U.S. Geological Survey (USGS), the world’s volcanoes, both on land and undersea, generate about 200 million tons of carbon dioxide (CO2) annually, while our automotive and industrial activities cause some 24 billion tons of CO2 emissions every year worldwide. Despite the arguments to the contrary, the facts speak for themselves: Greenhouse gas emissions from volcanoes comprise less than one percent of those generated by today’s human endeavors."
"Another indication that human emissions dwarf those of volcanoes is the fact that atmospheric CO2 levels, as measured by sampling stations around the world set up by the federally funded Carbon Dioxide Information Analysis Center, have gone up consistently year after year regardless of whether or not there have been major volcanic eruptions in specific years. “If it were true that individual volcanic eruptions dominated human emissions and were causing the rise in carbon dioxide concentrations, then these carbon dioxide records would be full of spikes—one for each eruption,” says Coby Beck, a journalist writing for online environmental news portal Grist.org. “Instead, such records show a smooth and regular trend.”"
And oceans absorb CO2, the opposite of what you're suggesting.
