Intelligence learns to think, and the grid learns what thinking costs

A UN report estimates global data centres consumed roughly 448 terawatt-hours of electricity in 2025, flagging AI's expansion as a major and growing environmental pressure — even as those same data centres train the models a generation now treats as infrastructure.

Here the two great accelerations of the age finally touch and reveal they are one system. The intelligence we are building to help us model the climate is itself becoming a load on the climate. The mind and the metabolism are no longer separable. We are watching a civilisation try to think its way out of a crisis using a method that adds heat to the crisis — and the silence around this collision is the silence of people who do not yet know whether the tool is the cure or the fever. Both stories ran this week. Almost no one ran them together.
