CO₂ and plant physiology

As the climate crisis intensifies, plants—the planet’s primary carbon assimilators—find themselves at the frontline of atmospheric change. Photosynthesis, the foundational process that converts solar energy and CO₂ into carbohydrates, is highly sensitive to shifts in temperature, light intensity, and CO₂ levels. While these environmental cues have always fluctuated, their unprecedented rate of change is now…
