Rate of growth in atmospheric carbon dioxide (CO2) emissions, 1960-2010, measured in ppmv per year. CO2 is rising faster now than it was just a few decades ago. tamino.wordpress.com

…CO2 is rising faster now than it was just a few decades ago. We can even estimate how the rate of increase is changing, by calculating the difference between CO2 concentration each month, and its value 12 months previously, to figure its annual change.

Clearly the annual change in CO2 concentration fluctuates. A lot. But it’s consistently positive, CO2 is growing. And there’s a trend there as well as fluctuation, an upward trend, because the rate of increase is itself increasing. I’ve superimposed a trend line on the above graph.

…CO2 continues to grow, significantly faster now than just a few decades ago. And it will continue to grow over the coming decades. How fast it grows depends on what we, as a global society, choose to do about it. …
