The One Earth study analyses how agriculture would be affected if emissions are left uncut. Climate change can have a significant negative impact on global food production, according to a new research led by Aalto University. The study published in the journal One Earth analyses how global food production will be affected if greenhouse gas emissions are left uncut. 'Our research shows that rapid, out-of-control growth of greenhouse gas emissions may, by the end of the century, lead to more than a third of current global food production falling into conditions in which no food is produced today - that is, out of safe climatic space,' explained Matti Kummu, professor of global water and food issues at Aalto University as quoted in an official release published in EurekAlert!.
