Plants adjusting to rising temperature

 The Telegraph:

Plants will absorb 20 per cent more carbon dioxide than predicted by the end of the century, a new study has found, suggesting climate models are overestimating how fast the planet will warm.

Trinity College Dublin said their research painted an ‘uncharacteristically upbeat picture for the planet’ after finding models had failed to take into account all the elements of photosynthesis.

During photosynthesis green plants use light energy from the sun to convert carbon dioxide, water and minerals into the sugars they need for growth.

Scientists had thought that climate change could weaken the process, but the new research suggests plants can adjust to the temperatures, efficiently absorbing carbon dioxide, producing extra nutrients, and continue to thrive.

They found that on a global scale, the amount of carbon converted during photosynthesis could be up to 68 per cent greater by the end of the century compared to the start of the century, and 20 per cent more than some current models suggest.

Silvia Caldararu, Assistant Professor in Trinity’s School of Natural Sciences, said: “What our study shows is that ecosystems could take up more CO2 out of the atmosphere than previously thought, which would mean lower CO2 concentrations, so a less steep rise in temperature.

This suggests that food production can be even greater than it is now and that it may be easier for the humans and animals to thrive.
