The study, which was published in Nature, demonstrates that soil moisture levels, which are influenced by temperature increases and extreme weather conditions like droughts, can have a "significant negative influence" on a region's capacity to store carbon.
It concludes that the "CO2 fertilizations effect," a process wherein rising CO2 levels in the atmosphere boost the growth and, consequently, carbon uptake of plants, would likely cause an increase in the pace at which land absorbs carbon until the second part of this century.
The lead author told Carbon Brief that after this, the fertilizations is anticipated to "hit a pinnacle". This peak, when paired with the detrimental effects of soil moisture changes, could significantly shift the land's role as a carbon sink to source greatly accelerating climate change.
