Scientific reconstruction
Deep Time
A multiscale reconstruction of climate, atmospheric composition, ocean chemistry, and biological change across Earth history, extending from early Earth through modern measurements and future scenarios.
Biological systems have repeatedly altered the physical conditions in which later life evolved. Deep Time places Carbocene’s current climate and biotechnology work within that longer history.
Interactive reconstruction
Earth history across eight nested time views.
Landscape and desktop open with the complete current view fitted. Portrait mobile opens at a readable magnification: drag horizontally with one finger, use two fingers to move in any direction or pinch, and choose Fit for the full temporal context.
Data & methodology
Different kinds of evidence remain distinct.
The reconstruction combines observations, proxy reconstructions, synthesized display bands, discrete constraints, and future scenarios. It does not present them as one homogeneous measured record.
The harmonized workbook preserves the original 15 research and source sheets and adds 14 sheets documenting the active display state, reconciliation decisions, sources, events, scenarios, proposed future intervals, time scales, and display methods. Named reconstruction layers can replace or augment base centerlines within defined intervals.
Deep-time ocean alkalinity is shown as a multiple of modern alkalinity. Industrial and modern ocean acidification is represented separately as surface-ocean pH; the two quantities are not interchangeable.
The earlier Deep Time essays record the intellectual and publication history behind parts of this work. The current reconstruction and source dataset are Carbocene scientific artifacts.
