“…higher atmospheric carbon dioxide…triggers…increased vegetation production and greener landscapes” – Chen et al., 2024
Plant transpiration is critical to plant growth and terrestrial ecosystems.
The rising trend in carbon dioxide emissions over the past 30 years (1990-2020) is the main driver of the increase in Earth's greenness, or Leaf Area Index (LAI).
Greening, in turn, is the main reason for the widespread increase in plant evapotranspiration during this period.
These upward trends in greening and plant transpiration are expected to continue until 2100 and accelerate as emissions increase.
Trend attribution analysis results show that changes in leaf area index (LAI) can explain 66.2% of the global PT trend, indicating that the increase in LAI caused by global greening is the dominant factor in the global PT rising trend. The increase in LAI is mainly attributed to the carbon dioxide fertilization effect caused by rising atmospheric carbon dioxide concentrations.
