s the concentration of carbon dioxide in our atmosphere has increased since the Industrial Revolution, global temperatures have also steadily increased. In other words, there’s a strong correlation between more carbon dioxide and higher temperatures.
And while the amount of carbon dioxide in our atmosphere has gone up and down over time, all the coal, oil, and gas we’ve burned over two-plus centuries mean it hasn’t been this high for hundreds of thousands of years. We’re simply adding more carbon dioxide into our world than it can absorb.
