Contemporary debates on climate change may be viewed as a clash between different histories of the planet's climate. Those pursuing the so-called "climate justice" position repeat a familiar narrative of the imperial tendencies of developed Western nations. Climate scientists on the other hand tell a history that operates on a much larger time-scale and addresses humanity as a whole. The assumptions about human agency are also different in the two narratives. This lecture examines this debate and its ramifications to raise questions about possible implications of this planetary crisis for narratives of human history.
