Precipitation will be essential for plants to counteract global warming

Photosynthesis on Earth is regulated by plant phenology—how plant life cycles interact with the climate—and environmental conditions, both of which changed substantially in recent decades. Unlike early-season photosynthesis which is mostly driven by warming temperatures or the onset of the wet season, late-season photosynthesis can be limited by several factors, such as plant life cycle and radiation, and its underlying mechanisms are less understood. Late-season photosynthesis on land contributes greatly to annual total carbon fixation and is sensitive to climate. Scientists generally agree that temperature limitation on late-season photosynthesis will alleviate with warming but the effects of water availability are highly uncertain.
