The last 12,000 years show a more complex climate history than previously thought

We rely on climate models to predict the future, but models cannot be fully tested as climate observations rarely extend back more than 150 years. ...

The illustrative example of mass spectrometry imaging on sediment. Imaging is performed on 5 cm long sediment section spanning the period of ca. 175 years of sediment deposition. The heat map indicates the spatial distribution of an alkenone-based proxy f
