Plants emit 30% more carbon than thought: Study

Such increases may lower the future ability of global vegetation to offset carbon dioxide emissions caused by burning of fossil fuels

released by may be around 30 per cent higher than previously predicted, a study has found.

from the University of Minnesota in the US suggest that as the mean global temperature increases, respiration will also increase significantly.


Such increases may lower the future ability of global vegetation to offset dioxide emissions caused by burning of fossil fuels.

"both capture dioxide and then release it by respiration. Changes to either of these processes in response to climate change have profound implications for how much ecosystems soak up dioxide emissions from burning fossil fuels," said Chris Huntingford, lead author of the study.

"In fact, this study provides the most up-to-date accounting of respiratory releases from in terrestrial systems," said Peter Reich, from the University of Minnesota.

The new findings, published in the journal Nature Communications, are based on the comprehensive GlobResp database, which is comprised of more than 10,000 measurements of dioxide from plant species around the globe.

Merging this data with existing computer models of global land cycling shows has been a potentially underestimated source of dioxide release.
