This year's record setting El Niño will impact many different parts of the world, with some experiencing severe drought and others flooding. In a new analysis at The Climate Brink, I explore what impacts happened during past events and which are most likely to occur this year

The impacts of this year’s record-shattering El Niño
El Niño will drive severe drought from Indonesia to the Southern Africa and northern South America, with wetter winters from the US Gulf Coast to Southern South America.

Understanding data uncertainty

ABSTRACT
Scientific data without uncertainty estimates are increasingly seen as incomplete. Recent discussions in the philosophy of data, however, have given little attention to the nature of uncertainty estimation. We begin to redress this gap by, first, discussing the concepts and practices of uncertainty estimation in metrology and showing how they can be adapted for scientific data more broadly; and second, advancing five philosophical theses about uncertainty estimates for data: they are substantive
adequacy-for-purpose view of uncertainty estimation, addresses a weakness in a recent philosophical account of data, and provides a new perspective on the "safety" versus "precision" debate in metrology.
1. Introduction
Uncertainty is an inescapable part of science. Yet while much has been written in recent years on uncertainty in computational modeling contexts (especially related to climate modeling; see, e.g., Parker, 2010;
Frigg, Thompson, & Werndl, 2015; Knutti et al., 2019), comparatively little philosophical attention has been given to uncertainty associated with scientific data collected via observation, measurement, and experiment. Important preliminary work on this topic examines the evaluation of systematic uncertainty in measurement (Staley, 2020), changing conceptions of uncertainty in metrology (de Courtenay & Grégis, 2017; Grégis, 2019b), and the representation of uncertainty when measurements are discordant (Grégis, 2019a). Overall, however, when it comes to uncertainty associated with scientific data obtained via observation, measurement, and experiment—what we will call "data uncertainty"-the territory remains largely unexplored from a philosophical point of view.
Conception…
