    According to the NOAA’s Global Monitoring Division, “The present concentration is the highest during the last 650,000 years and probably during the last 20 million years.” The growth rate of CO2 concentrations this decade is 2.1 ppm (parts per million) a year — 40% higher than the rate from the 1990s. According to some scientists, this trend could indicate that the Earth is losing its natural ability to soak up billions of tons of carbon each year.

    Until we’re successful at reducing output, the answer is going to keep being “next year”.
