Rising CO2 Is Making African Savanna Grasses Grow More, Study Finds

Research combining 70 experiments, three decades of field data from Kruger National Park and computer modelling found grass production rose 28% between 1989 and 2021 as atmospheric CO2 climbed about 18%. The growth boost came mainly from grasses using scarce water more efficiently, and the study's authors say it does not mean the extra growth offsets global warming.
