UN Secretary-General Antonio Guterres says the world is "not on track" to limit global temperature rises to 1.5 per cent, TVNZ reports during his visit to New Zealand.
Speaking to the media in Auckland alongside New Zealand's Prime Minister Jacinda Ardern, Guterres on Sunday warned about the dangers of not addressing climate change.
"Climate change is running faster than what we are ... the last four years have been the hottest registered," TVNZ quoted Guterres as saying.
Countries vowed under the 2015 Paris climate agreement to try to limit a rise in global warming even further to 1.5 degrees Celsius.
According to local media, Guterres also said he wished to show solidarity during Ramadan with those affected by the deadly Christchurch attacks on March 15.
"To pay tribute to their courage, to their resilience but also to pay tribute to extraordinary unity and to the message of solidarity that was given by the people and the government of New Zealand," TVNZ reported.
Guterres arrived in New Zealand on Sunday and will later also travel to Tuvalu, Vanuatu and Fiji as part of a Pacific tour focused on climate change.
