| What Are the "Unknown Unknowns" of climate Change? Issue1 #472966 For obvious reasons it is impossible to specifically list "unknown unknowns" of climate change. But it is still a useful frame for thinking about fundamental uncertainties in how climate change will play out. Could the climate system hit a tipping point, perhaps based on methane emissions, that is not built into any of the climate models? Could climate change result in far more sea level rise than most scientists anticipate? These outcomes are so uncertain they can be called unknown unknowns. |
