Scientists have known for some time that their predictive models of global warming were at increasing odds with the data. More recently, they have begun to pinpoint some of the faulty assumptions in the models used to make projections (not observations) of global warming. One example of this type of correction is a 2018 article published in the prestigious journal, Science.
Nitrogen availability is a central controller of terrestrial plant growth and, thereby, of the carbon cycle and global climate change. It has been widely assumed that the atmosphere is the main source of terrestrial nitrogen input. Surprisingly, Houlton et al. now show that bedrock is just as large a nitrogen source across major sectors of the global terrestrial environment.
Climate scientists have long known that plants offset some of the effects of climate change by absorbing and storing CO2. But they assumed that the ability to plants to perform this function was limited because the availability of nitrogen in the atmosphere was limited. As an earlier 2003 study published in Science stated, “there will not be enough nitrogen available to sustain the high carbon uptake scenarios.”
But this idea that the only source of nitrogen for plant life came from the air has been refuted in a more recent article, also in Science … READ ALL >>>
