Multidecadal preindustrial methane variability can be explained by noise in the source–sink imbalance | PNAS
Ice core records of preindustrial methane indicate variability of ±30 ppb (±5%) on multidecadal-to-centennial timescales. Previous work has attribu...

Just out in @natgeosci.nature.com we use ice sheet modeling to identify & characterize behavioral regimes, & the nature of ice sheet regime shifts. We do this using the Shannon entropy signature of mass loss, and find evidence of bistability under high, but not low, entropy regimes. rdcu.be/fmIe1
Ice-sheet regime shifts with climate warming
Nature Geoscience - Ice sheets are steady in cold climates, become unstable as warming weakens ice shelves, then restabilize at higher temperatures. Model simulations suggest sudden shifts between...
