Nick Scroxton @stalagnick.bsky.social · 05/02/2025We created time-slice maps to compare our work with BritIce-Chrono.

Nick Scroxton @stalagnick.bsky.social · 05/02/2025In detail, we compiled all published ages from nearly fifty years of speleothem research.

Nick Scroxton @stalagnick.bsky.social · 02/01/2025We did find an abrupt isotopic enrichment 3.9-3.6 kyr BP. This ‘tropical climate shift’ is becoming more and more evident in high-res records and is temporally distinct to 4.2 (take note low res records), supporting previous work and the Double Drying hypothesis (Scroxton et al., 2023). 241 0
Nick Scroxton @stalagnick.bsky.social · 02/01/2025In detail, we used a network of 14 high-res speleothems and some fancy stats (Laplacian Eigenmaps for Recurrence Matrices and Monte Carlo Principal Component Analysis).

Nick Scroxton @stalagnick.bsky.social · 20/12/2024Sphere is a relatively succinct way of saying a physical area surrounding a point. I think we need to understand both spheres to understand how climate events propagate through the climate system. Knowing where something might have impacted is still important even if it is not of unusual magnitude. 000 0
Nick Scroxton @stalagnick.bsky.social · 19/12/2024Of course, seeing an event at the right time but not of unusual magnitude is no guarantee of it being the event in question. Individual studies must therefore be more cautious of positive results bias and confirmation bias when it comes to abrupt climate change events. 010 0
Nick Scroxton @stalagnick.bsky.social · 19/12/2024We posit a difference in language where different studies target different spheres of influence of a climate event: individual studies delineate a 'detection sphere', while statistical studies delineate an 'impact sphere'. The difference being the relative significance/magnitude of the event. 221 0
