Arab Weather - A scientific study revealed that the fall of tree leaves in the fall occurs earlier than in previous decades, as a result of climate change, which contradicts previous expectations.

The impact of climate change on carbon sequestration

The study indicates that forests have a limited capacity to absorb carbon annually, which limits their role in combating greenhouse gas emissions, and this change in the timing of leaf fall weakens the ability of forests to adapt to rising levels of carbon in the atmosphere.

Warming and leaf fall

Botanists have long studied the factors that influence the timing of seasonal tree processes, such as leaf growth in the spring and leaf drop in the fall. Scientists have found a link between warmer spring temperatures due to climate change and earlier bud growth. However, tree behavior in the fall has remained poorly understood.

Factors affecting the timing of leaf fall

Scientists agree that cooler temperatures in the fall and shorter daylight hours are the primary factors in determining when leaves fall. Deciduous trees, which shed their leaves seasonally, do so to conserve energy during cold weather and reduced photosynthesis, relying on sugars stored during the winter.

Previously, scientists thought that rising temperatures would delay leaf fall by two to three weeks by the end of the century. But the new study suggests that delay may not happen as expected.
