Atmospheric levels of CO2 have risen from approximately 280 ppm pre-industrial to nearly 400 ppm today. Over the past two centuries, warming oceans released … CO2 and Past Climates As a point of reference, pre-industrial CO2 levels were around 280 parts per million (ppm) and today, we stand at 410ppm. The most distant period in time for which we have estimated CO2 levels is around the Ordovician period, 500 million years ago. At the time, atmospheric CO2 concentration was at a whopping 3000 to 9000 ppm!

All farmers should consider CO2 as a nutrient. CO2 levels in the atmosphere today are NOT at record high levels. Carbon dioxide is such a small component of Earth’s atmosphere (380 parts per million or 0.038%) that it shows up on the chart below as only a thin line (shown at 2x actual thickness, just so you can see it!).
