The image below illustrates the amount of carbon dioxide in our atmosphere. For hundreds of thousands of years, you can see that a trend of a gradual decline, followed by a sharp increase is evident. You can see where humans come into the equation and the increase is enormous.
Carbon dioxide is a greenhouse gas, as is methane, which is also rapidly increasing. In other words, they trap heat. The atmosphere of Venus is composed mostly of carbon dioxide and temperatures on the planet are on average over 800 degrees fahrenheit.
Even if the entire planet becomes acutely aware of this and changes the ways we are impacting the planet, we will likely feel the effects of our contribution for hundreds of years to come.
Do you believe humans are partially responsible for this phenomena? Can we come back from this, or are our actions irreversible at this point? What do you think has caused the natural rise and fall of carbon dioxide in our atmosphere in the distant past?
