JUNEAU, Alaska – The Tongass National Forest is playing a significant role in the fight against climate change, according to new research. Dominick DellaSala, chief scientist with Wild Heritage, has been cataloging biodiversity in the world’s rainforests since the early 1990s. He says the Tongass is the most carbon-dense forest on the planet. “Alaska is ground zero in climate change,” DellaSala said. “I mean you folks have the fastest-changing ecology and climate among the fastest places on the planet. Especially the interior of Alaska, which is experiencing very unusual high temperatures, the melting of the permafrost, the fires that are happening in Alaska. “Most of that is the result of climate chaos.”
