Yale Environment 360: Marshes may be more resilient to climate change and associated rises in sea level than previously thought, according to recent research published in the Proceedings of the National Academy of Sciences. The study shows that as levels of atmospheric carbon dioxide increase, more CO2 gets taken in by marsh plants. This spurs higher rates of photosynthesis and plant growth, causing marsh plants to trap more sediment above ground and generate more organic soil below ground, the researchers explain. The...
