 | | Toward the end of the nineteenth and at the beginning of twentieth century significant discussions occurred among geographers, meteorologists and " climatologists" concerned with the notion of climate variability (Klimaschwankungen) and anthropogenic climate change (Klimawandel/Klimaänderungen), for instance, due to deforestation and reforestation. |
 | | We identify two protagonists of this debate, Eduard Brückner and Julius Hann, who both accept the notion of climate variability on the decadal scale, but respond in very different ways to the discovery of climate change. |
 | | Brückner assessed the impact of climate variability on society (e.g., on health, the balance of trade, emigration to the USA), and tried to bring these to the attention of the public, whereas Hann limited himself to the immediate natural scientific problem of monitoring and documenting climate variability. |
