The Recent Thaw

The impacts of recent permafrost thaw on land–atmosphere greenhouse gas exchange

Permafrost thaw and the subsequent mobilization of carbon (C) stored in previously frozen soil organic matter (SOM) have the potential to be a strong positive feedback to climate. As the northern permafrost region experiences as much as a doubling of the rate of warming as the rest of the Earth, the vast amount of C in permafrost soils is vulnerable to thaw, decomposition and release as atmosph...

Freeze-Thaw Bayesian Optimization

In machine learning, the term “training” is used to describe the procedure of fitting a model to data. In many popular models, this fitting procedure is framed as an optimization problem, in which a loss is minimized as a function of the parameters. In all but the simplest machine learning models, this minimization must be performed with an iterative algorithm such as stochastic gradient descen...

Is the January Thaw a Statistical Phantom?

JANUARY 2002 AMERICAN METEOROLOGICAL SOCIETY | M eteorological conditions that tend to occur on or near a specific calendar date more frequently than chance might suggest have been termed singularities (e.g., Huschke 1959) or calendaricities, a term introduced by Brier et al. (1963) to avoid confusion with the mathematical usage of “singularities.” These features are commonly identified as cons...
