A climate model projection weighting scheme accounting for performance and interdependence

R Knutti, J Sedláček, BM Sanderson… - Geophysical …, 2017 - Wiley Online Library
Uncertainties of climate projections are routinely assessed by considering simulations from
different models. Observations are used to evaluate models, yet there is a debate about …

Climate model dependence and the replicate Earth paradigm

CH Bishop, G Abramowitz - Climate dynamics, 2013 - Springer
Multi-model ensembles are commonly used in climate prediction to create a set of
independent estimates, and so better gauge the likelihood of particular outcomes and better …

[HTML][HTML] Risks of model weighting in multimodel climate projections

AP Weigel, R Knutti, MA Liniger… - Journal of …, 2010 - journals.ametsoc.org
Multimodel combination is a pragmatic approach to estimating model uncertainties and to
making climate projections more reliable. The simplest way of constructing a multimodel is to …

On the interpretation of constrained climate model ensembles

BM Sanderson, R Knutti - Geophysical Research Letters, 2012 - Wiley Online Library
An ensemble of models can be interpreted in two ways. The first treats each model as an
approximation of the true system with some random error. Alternatively, the true system can …

Taking climate model evaluation to the next level

V Eyring, PM Cox, GM Flato, PJ Gleckler… - Nature Climate …, 2019 - nature.com
Earth system models are complex and represent a large number of processes, resulting in a
persistent spread across climate projections for a given future scenario. Owing to different …

How well must climate models agree with observations?

D Notz - Philosophical Transactions of the Royal Society …, 2015 - royalsocietypublishing.org
The usefulness of a climate-model simulation cannot be inferred solely from its degree of
agreement with observations. Instead, one has to consider additional factors such as …
