“The Climate of History: Four Theses” is one of the decisive texts for thinking the collapse between human history and earth history. Dipesh Chakrabarty argues that climate change forces a profound disturbance in the categories through which modern historical thought has usually operated: freedom, capitalism, empire, progress, class, species and agency. The human being can no longer be understood only as a political, economic or cultural actor; under the pressure of global warming, humanity also appears as a geological force. This does not erase inequality or colonial history, but it complicates them by placing human action inside planetary processes that exceed ordinary political time. The essay’s strength lies in its tension: Chakrabarty does not dissolve history into nature, nor does he reduce climate change to another chapter of capitalism alone. Instead, he asks how historical thinking must change when the human species becomes implicated in transformations of the earth system. The text matters because it opens a difficult intellectual threshold: the crisis is at once historical and planetary, political and species-level, immediate and deep-time.
