Global plant growth increased as climate changes eased environmental constraints
In short: Researchers analyzing 18 years of satellite observations and climate data found that global terrestrial net primary production increased by 6% between 1982 and 1999. This growth, totaling 3.4 petagrams of carbon, was driven by changes in climate that reduced critical limitations on plant development.
The study investigated how vegetation responds to shifting climate patterns by comparing satellite imagery with climatic data. The findings highlight how reduced cloud cover in the tropics allowed for more solar radiation, significantly boosting productivity in the Amazon. However, the results are based on a specific 18-year window and rely on satellite-based observations of vegetation activity.
Why it matters: Climate-driven changes in light and temperature can temporarily boost the earth's ability to absorb carbon through plant growth.
