Harjeet Singh, Global Lead for Climate Change at ActionAid International, says:
"As the recent UN climate talks end in deadlock, Guterres message sends a strong signal to rich countries that they must stop backtracking on their commitments. With every month bringing a new climate disaster, the Secretary-General's landmark warning comes not a minute too soon.
"Government leaders, businesses and citizens need to hear this wake-up call and recognise that addressing climate change will require much more than they are currently doing.
"Believing in climate change, yet refusing to take the action necessary is just another form of climate denial. Rich countries must shift dramatically away from polluting economies and lifestyles, and help fund the transformation to a safe and sustainable future."
