An ice-core record of hydrogen reveals that atmospheric levels vary in response to climate change and have increased drastically owing to human activity since the pre-industrial era. The apparent sensitivity of hydrogen cycling to environmental conditions should be considered when projecting the consequences of rising anthropogenic hydrogen emissions in a warming climate.
