Hawaii -- 

Aloha. Welcome to the “Big Island.” The Island of Hawaii is a volcanic island in the Pacific Ocean. Hawaii is the easternmost and southernmost in the Hawaiian Islands chain. It is also one of eight major islands that make up the U.S. state of the same name, Hawaii. Built from five separate volcanoes, Hawaii still boasts three active ones.

On one of these volcanoes, Mauna Loa, sits the Mauna Loa Observatory, an atmospheric research facility established by the U.S. National Oceanic and Atmospheric Administration as part of the National Weather Service. Scientists at Mauna Loa began continuous carbon dioxide data gathering efforts in 1958. According to NOAA’s website, the annual increases in the concentrations of carbon dioxide in the atmosphere became apparent within just a few years of the launch of this effort. Today, climate scientists and modelers around the world use the Mauna Loa data to better understand the current state of Earth’s climate — and project how it will change in the future.
