Pacific Walrus and climate change: observations and predictions
The extent and duration of sea-ice habitats used by Pacific walrus (Odobenus rosmarus divergens) are diminishing resulting in altered walrus behavior, mortality, and distribution. I document changes that have occurred over the past several decades and make predictions to the end of the 21st century. Climate models project that sea ice will monotonically decline resulting in more ice-free summer...
متن کاملEnsemble climate predictions using climate models and observational constraints.
Two different approaches are described for constraining climate predictions based on observations of past climate change. The first uses large ensembles of simulations from computationally efficient models and the second uses small ensembles from state-of-the-art coupled ocean-atmosphere general circulation models. Each approach is described and the advantages of each are discussed. When compar...
متن کاملLinguistics in Computational Linguistics: Observations and Predictions
As my title suggests, this position paper focuses on the relevance of linguistics in NLP instead of asking the inverse question. Although the question about the role of computational linguistics in the study of language may theoretically be much more interesting than the selected topic, I feel that my choice is more appropriate for the purpose and context of this workshop. This position paper s...
متن کاملOn the credibility of climate predictions
Geographically distributed predictions of future climate, obtained through climate models, are widely used in hydrology and many other disciplines, typically without assessing their reliability. Here we compare the output of various models to temperature and precipitation observations from eight stations with long (over 100 years) records from around the globe. The results show that models perf...
متن کاملQuantifying the Uncertainty in Climate Predictions
Uncertainties in projections of future climate change caused by an increase in greenhouse gas concentrations have been a subject of intensive study in recent years. However, in most cases, uncertainties in parameters and characteristics of models used to obtain those projections, such as climate sensitivity or radiative forcing, are described only by ranges of possible values. The resulting unc...
