Secretary of State John Kerry warned on Monday that scientific evidence for climate change is "irrefutable" and "alarming."
He also urged the international community to take action to stop it.
"If we continue down our current path, the impacts of climate change will only get worse."
Kerry said that climate change is a global problem and nations must work together to take immediate action to prevent any further harm to the Earth.
"I stand with you in the fight against climate change," he told attendees.
"If we act together, there is still time to prevent some of the worst impacts of climate change," Kerry added. "But the people of the Pacific Islands know as well as anyone that we also need to prepare communities for the impacts that are already being felt."
Kerry spoke on the eve of the Pacific Islands Forum. Many PIF member nations stand to suffer damage if rising waters engulf their land.
President Obama introduced a plan to combat climate change earlier this year, comprised mainly of actions his administration can take without congressional approval.
The plan was met with some skepticism, largely by Republicans, who believe Obama's climate policies hurt business growth and needlessly drive up energy costs.
