Hawaii has become the first sub-national government to sign onto the Majuro Declaration for Climate Leadership.
Governor Abercrombie says it's the latest commitment by the state to reduce greenhouse gas emissions.
On Monday, a team of University of Hawaii researchers shared the results of a 2,000 page report by the Intergovernmental Panel on Climate Change, which was conducted by more than 250 scientists.
The latest report indicates since 1950, humans are clearly responsible for more than half of the observed increase in temperatures.
The scientists say that sea level rise will proceed at a faster rate than we have experienced over the past 40 years.
"It would be a lot harder for beaches to survive if sea level rises two to three feet. Can imagine Waikiki having a hard time keeping sand on beach with water that high," said UH Oceanography Professor Mark Merrifield.
This is the 5th IPCC report scientists have released since the late '90s on climate change.
The latest report adds that a pause in warming over the past 15 years is too short to reflect long-term trends.
