NADI: Countries must urgently scale up their commitments to keep temperature rises within 1.5C (2.7 degrees Fahrenheit) to limit the impacts of extreme weather, a statement from a conference leading up to the UN's COP31 summit said.

The ministerial meeting, being held in Fiji and Tuvalu, said on Tuesday that "deep, rapid and sustained emissions reductions are required to minimise the magnitude and duration of overshoot" of the target.

"As global temperature increases approach 1.5C and we face strong El Nino conditions, we reiterate that every fraction of a degree of warming accelerates the impacts of climate change and increases the risk of irreversible loss and damage for climate vulnerable communities," the statement said.
