A global study has shown that over the past two decades, the Earth has noticeably increased the rate of photosynthesis — a key process on which life on the planet depends. Satellite data for 2003–2021 showed that areas with increases accounted for almost one-third of all vegetated land, while declines were recorded on only 3.3% of the area. The largest changes occurred in northern latitudes and mountains: that is where plants are now absorbing more carbon dioxide.
In tropical America, the growth in bioproductivity is being held back by deforestation, but a positive trend persists in other parts of the tropics. Overall, the tropics remain the "heart" of photosynthesis. According to estimates, due to increased plant activity, about 0.20 billion tons of carbon are additionally bound each year.
In the oceans, the dynamics are mixed: growth was recorded on only 5% of the water area, while declines were seen on 18.5%. However, the trend on land is clear and offers reason for optimism. Terrestrial ecosystems are now acting as a powerful buffer, retaining excess carbon. Nature is responding to climate change not only with problems, but also with increased productivity of its own.
