The Surprising Role of Plants in Air Pollution and Climate Change

New research from Michigan State University reveals that on a warming planet, plants like oaks and poplars will emit more isoprene, a compound that exacerbates poor air quality and contributes to particulate matter and low-atmosphere ozone. Isoprene can also improve the quality of clean air and make plants more resilient to stressors. The study aims to understand the biomolecular processes behind isoprene production and how they are affected by the environment, particularly in the face of climate change. The findings suggest that increasing temperatures have a greater impact on isoprene production than increasing carbon dioxide levels. The research highlights the need for better control of nitrogen oxide pollution and informed decision-making regarding tree planting to mitigate isoprene emissions.
