But the biggest problem with the Pinatubo Option is that it does nothing to change the underlying cause of climate change, the buildup of heat-trapping gases, and instead treats only the most obvious symptom—warmer temperatures. That might help control something like glacial melt, but would do nothing about the increased atmospheric carbon that the ocean continues to soak up, causing rapid acidification that is already taking a heavy toll on hard-shelled marine life from coral to oysters, and may have cascading impacts through the entire aquatic food chain.
