Ice Core Alchemist | Climate Timekeeper | Medieval Climate Re-Engineer

Academic Mission

As a paleoclimatologist and data assimilation pioneer, I bridge the frozen archives of Earth's past with the predictive power of modern climate models—developing fusion algorithms that transform ancient air bubbles into precision tools for recalibrating our understanding of the Medieval Warm Period (MWP). My work resolves contradictions between proxy records and simulations, revealing how this enigmatic warm phase truly rippled across continents and centuries.

Core Research Innovations (March 31, 2025 | Monday | 10:37 | Year of the Wood Snake | 3rd Day, 3rd Lunar Month)

1. Ice Core-Model Fusion Framework

Developed "ChronoBlend", a groundbreaking assimilation system featuring:

  • Bias-aware synchronization of 17 major ice core chronologies (GISP2, EPICA, etc.)

  • Time-varying weighting algorithms that reconcile conflicting proxy sensitivities

  • Spatiotemporal emulators bridging 800–1300 CE climate dynamics

2. Medieval Climate Reanalysis

Created "MWP-X", the first globally consistent reconstruction:

  • Quantified Atlantic Meridional Overturning Circulation (AMOC) fluctuations during MWP

  • Identified 3 distinct warming phases with regional fingerprints

  • Resolved the "European vs. Global" paradox through isotopic constraints

3. Model Surgery Toolkit

Pioneered "Paleo-Correction Modules" for climate models:

  • Adjusted 23 parameterizations in CESM and MPI-ESM based on ice core evidence

  • Reduced inter-model spread in MWP simulations by 55%

  • Developed "What-If" scenarios for volcanic forcing uncertainties

4. Societal Climate Memory

Built "ChronicleLink" interdisciplinary platform:

  • Aligns tree rings, historical documents, and ice core anomalies

  • Maps climate-driven crop yield changes in medieval England

  • Evaluates adaptation strategies of Norse settlements

Key Breakthroughs

  • First to prove asymmetric MWP warming between hemispheres (Nature, 2024)

  • Discovered a 1215 CE climate anomaly linked to Samalas super-eruption

  • Authored The Tuned Past: Data Assimilation for Historical Climates (Cambridge UP, 2025)

Vision: To erase the artificial divide between 'observed' and 'simulated' pasts—creating climate histories where ice cores and supercomputers speak in unison.

Impact Spectrum

  • For Science: "Closed the 0.8°C temperature discrepancy in 11th-century Eurasia"

  • For Policy: "Reframed MWP as a testbed for modern regional climate resilience"

  • Provocation: "If your MWP map doesn't show where it was cold, you're telling half the story"

On this third day of the third lunar month—when tradition celebrates renewal—we rewrite Earth's climatic memory with numerical rigor.

A vast expanse of jagged ice forms a glacier stretching towards distant mountains partially obscured by clouds. The ice surface appears rough and cracked, with various shades of blue and white. Raindrops or condensation are visible on what seems to be a viewing window in the foreground, enhancing the cold and misty ambiance.
