CO2 can stimulate plant growth, but only when enough nitrogen is available—and that key ingredient has been seriously miscalculated. A new study finds that natural nitrogen fixation has been overestimated by about 50 percent in major climate models. This means the climate-cooling benefits of plant growth under high CO2 are smaller than expected. The result: a reduced buffer against climate change and more uncertainty in future projections.

        It’s not that reckless of a prediction.

        "Highlights

        Earth’s temperature has risen by an average of 0.11° Fahrenheit (0.06° Celsius) per decade since 1850, or about 2° F in total.
    The rate of warming since 1982 is more than three times as fast: 0.36° F (0.20° C) per decade.
2024 was the warmest year since global records began in 1850 by a wide margin.
    It was 2.32 °F (1.18 °C) above the 20th-century average of 57.0 °F (13.9 °C).
    It was 2.62 °F (1.35 °C) above the pre-industrial average of 56.7 °F (1850-1900).
The 10 warmest years in the historical record have all occurred in the past decade (2015-2024). "
