An international team of scientists, including climate scientists from the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), investigated this question and found that accounting for phosphorus-deficient soils reduced projected carbon dioxide uptake by an average of 50% in the Amazon, compared to current estimates based on previous climate models that did not take into account phosphorus deficiency. The Amazon Basin is critical to help mitigate climate change due to its trees absorbing around a quarter of the CO2 released each year from the burning of fossil fuels.
The paper, "Amazon forest response to CO2 fertilization dependent on plant phosphorus acquisition," was published August 5 in the journal Nature Geoscience.

"Most predictions of the Amazon rainforest's ability to resist climate change are based on models that have outdated assumptions; one of those is that a sufficient supply of nutrients such as phosphorus exist in soils...
