A recent study indicates that the rate of energy captured by photosynthesis, known as “gross primary production,” could potentially increase towards the end of the century under high-emission scenarios. Lead author Dr. Jürgen Knauer from Western Sydney University’s Hawkesbury Institute for the Environment emphasizes the uncertainty surrounding plants’ future carbon dioxide (CO2) uptake and highlights the role of a well-established climate model in predicting sustained carbon uptake until the 21st century’s close.
Dr. Knauer explains that while plants annually absorb a substantial amount of CO2, mitigating the impact of climate change, uncertainties existed regarding their future capacity. The study, using detailed ecological models, addresses concerns raised by previous research suggesting reduced CO2 absorption in extreme climate conditions. The models consider critical physiological processes governing photosynthesis that are often overlooked in global assessments.
