The stepped-up diplomacy will culminate with a climate action summit at the United Nations in September, an event billed as a last chance to prevent irreversible climate change.

"We are still losing the battle," Guterres told reporters last week. "Climate change is still running faster than we are, and if we don't reverse this trend, it will be a tragedy for the whole world."

In Fiji, Tuvalu and Vanuatu, Guterres will meet with families whose lives have been upended by cyclones, flooding and other extreme weather events.

Pacific island countries face an especially dire risk from climate change because of sea level rise. In some cases, low-lying countries could disappear completely.

Fiji is working to build a coalition of more than 90 countries from the Caribbean, Africa and Asia facing climate crisis.

"We hope that the secretary-general will draw far more inspiration from his first visit to go further, faster and deeper with the climate summit," Fiji's UN Ambassador Satyendra Prasad told AFP.

"We are very hopeful that the climate summit will mark a turning point."
