How Close Are We to a Climate Tipping Point?

The Gulf Stream keeps Denmark mild, yet climate shifts are not always gradual. Evidence from Greenland's ice cores shows that past climate shifts have occurred within just decades. Could the ocean currents that warm Northern Europe switch off again – and how would we recognize the warning signs?

Climate physicist Peter Ditlevsen from the Niels Bohr Institute explains what tipping points are, what early-warning signals precede them, and how close we might be. In 2023, he gained widespread recognition for co-authoring a study warning of potential Atlantic current system collapse within this century.
