As you've probably heard, the lava flows have cut through the road to Mauna Loa Observatory, cutting off access and power. Let's be clear: What's remarkable (and lucky for the world!) that this hasn't happened since 1984 -- MLO *is* built on an active volcano.
CO2 measures will continue globally at many sites. Fortunately so far, MLO itself is spared. But restoring power and access will be no joke.
