Yes, human contribution to CO2 is minimal, much less than animals, and volcanoes and oceanic and terra plant life breakdown, but it is hard to
measure and know for sure.
Humans do not drive Earth's CO2 and do not drive temperature while other factors, the Sun, volcanoes, animals, the ocean and organic plant material
deterioration may be a driver of global CO2.
Focus on things you control, like dumping depleted uranium bombs, chemicals, plastics, and destructive food/fish production.
Consider, that many things you were told are wrong and take time to do some research beyond a single source to multiple sources and think outside the
box. As humans we have so much to learn and so little we know for certain. |
Volcanoes again?
"Carbon dioxide (CO2) is a greenhouse gas and is the primary gas blamed for climate change. While sulfur dioxide released in contemporary volcanic
eruptions has occasionally caused detectable global cooling of the lower atmosphere, the carbon dioxide released in contemporary volcanic eruptions
has never caused detectable global warming of the atmosphere. In 2010, human activities were responsible for a projected 35 billion metric tons
(gigatons) of CO2 emissions. All studies to date of global volcanic carbon dioxide emissions indicate that present-day subaerial and submarine
volcanoes release less than a percent of the carbon dioxide released currently by human activities. While it has been proposed that intense volcanic
release of carbon dioxide in the deep geologic past did cause global warming, and possibly some mass extinctions, this is a topic of scientific debate
at present."

I might add that those possible volcanic extinctions occurred as a result of immense volcanic fields erupting over thousands of years (The Siberian
and Deccan Trap episodes).
We are vaporizing 200 million years of carbon that has been locked up in the Earth's crust in the span of a couple centuries. I grant you that in
previous interglacial periods like this current one 400 ppm was reached before man was barely a twinkle of an influence on the environment. However
we are accelerating that milestone before other past interglacial timelines. Time will tell. |
