the waters around Hawaii have been warming since the 1950s, with temperatures rising by several degrees from the ocean surface down to at least 600 feet. Rising water temperatures can harm the algae that live inside corals, which can kill the corals

Increasing ocean acidity can also damage corals, shellfish, and other organisms that depend on minerals in the water to build their skeletons and shells. The acidity of the Pacific Ocean is likely to increase another 40- 50 % by 2100.

Since 1960, sea level has risen between 2-8 in relative to Hawaii’s shoreline. Sea level rise can make Hawaii’s waves, hurricanes, tsunamis, and extreme tides even worse.

Higher temperatures and increased drought have caused dramatic declines among native plant species such as Haleakalā silver- sword.

Rising sea level has accelerated coastal erosion, which has resulted in wetland migration and cliff collapse.
