📚 Plants May Be Absorbing 20% More CO2 Than We Thought, New Models Find

An anonymous reader writes: Using realistic ecological modeling, scientists led by Western Sydney University's Jürgen Knauer found that the globe's vegetation could actually be taking on about 20% more of the CO2 humans have pumped into the atmosphere and will continue to do so through to the end of the century. "What we found is that a well-established climate model that is used to feed into global climate assessments by the likes of the IPCC (Intergovernmental Panel on Climate Change) predicts stronger and sustained carbon uptake until the end of the 21st century when extended to account for the impact of some critical physiological processes that govern how plants conduct photosynthesis," said Knauer. Mathematical models of ecological systems are used to understand complex ecological processes and in turn attempt to predict how the real ecosystems they're based on will change. The researchers found that the more complex their modeling, the more surprising the results – in the environment's favor. Current models, the team adds, are not that complex so likely underestimate future CO2 uptake by vegetation... [T]he modeling makes a strong case for the value of greening projects and their importance in comprehensive approaches to tackling global warming.
