Here are some other facts about CO2:

The concentration of CO2 in the atmosphere has been increasing since the Industrial Revolution. 

Before the Industrial Revolution, CO2 levels were around 280 ppm for almost 6,000 years. 

The current rates of increase of CO2 are unprecedented over at least the last 800,000 years. 

The rapid rise in CO2 levels threatens the world with climate breakdown. 

In 2023, global energy-related CO2 emissions grew by 1.1% to a new record high of 37.4 billion tonnes
