Abstract
Havet transporterer enorme mængder energi fra troperne til polerne via vinddreven og termohalin cirkulation. Artiklen beskriver Nordatlantens rolle, hvor dybvandsdannelse i Grønlandshavet og Labradorhavet driver en global 'transportbånd'-cirkulation. Isotopmålinger af 14C afslører vandmassenes alder og giver indsigt i omsætningstider. Enkle boksmodeller illustrerer, hvordan ændringer i ferskvandsinput kan destabilisere cirkulationen, hvilket kan forklare hurtige klimaskift i fortiden. Resultaterne viser, at havstrømme både stabiliserer og kan forstærke klimaændringer.
