As world temperatures rise, the rate at which plants in certain regions can absorb carbon dioxide is declining, according to University of Queensland research.
Over a three year period, researchers took direct measurements of plant absorption of CO2 in subtropical coastal ecosystems in eastern Australia.
Professor Hamish McGowan, from UQ’s School of Earth and Environmental Sciences, said the team found the optimum temperature for photosynthetic production was routinely exceeded in these regions.
“Plants’ optimum temperature range for photosynthesis in our study area is between 24.1 and 27.4 degrees Celsius,” Professor McGowan said.
