“…In the absence of air temperature data prior to 1970 on the north shore of Fraser Lake, the monthly records from Fort St. James are used. Following Mudelsee (), a linear regression between the average November, December, and January air temperatures at Fort St. James and ice duration on Francois Lake for 1934–1954 is computed. Based on the resulting linear regression, ice duration on Francois Lake is reconstructed from 1970 to 2009 using the November, December, and January air temperatures from Fort St. James.…”

Insights from both western science and traditional knowledge were applied to identify, and begin to address, climate change and water impacts at Stellat'en First Nation, British Columbia, Canada. Qualitative data from interviews and surveys of Stellat'en community members were compiled and compared with air temperature, precipitation, and hydrometric data from meteorological stations and proximal rivers. Community Elders noted changes to river water levels and shifts in fish populations. The quantitative data revealed a 2.3 °C rise in air temperature, 5 percent increase in precipitation, and 10 percent decline in snowfall over a 40‐year period. Results from these analyses were reported in two knowledge intersection workshops at Stellat'en First Nation, and information sharing took place to: facilitate discussion and awareness between traditional and western knowledge holders, gain insights on the community's views of climate change and water, and identify strategies for action. Recommendations formulated and implemented by Stellat'en First Nation include improved policies, and community and individual actions. Les changements climatiques et les ressources en eau dans la Première nation Stellat'en, Colombie‐Britannique, Canada : les connaissances issues de la science occidentale et des savoirs traditionnels Le recours aux connaissances issues de la science occidentale et des savoirs traditionnels a permis d'identifier, puis d'aborder les répercussions des changements climatiques sur les ressources en eau dans la Première nation Stellat'en, Colombie‐Britannique, Canada. Les données qualitatives obtenues au moyen d'entrevues et d'enquêtes menées auprès de membres de la communauté Stellat'en ont été colligées et comparées à des données de température de l'air, de précipitations et d'hydrométrie recueillies de stations météorologiques et de rivières des environs. Les sages de la communauté ont observé des changements des niveaux d'eau de la rivière ainsi que des variations dans les populations de poissons. Les données quantitatives mettent en évidence une hausse de 2,3 °C de la température de l'air, une augmentation des précipitations de l'ordre de 5 pour cent, et une réduction des chutes de neige de l'ordre de 5 pour cent sur une période de 40 ans. Les résultats qui ressortent de ces analyses ont été présentés au cours de deux ateliers d’échanges sur les savoirs dans la Première nation Stellat'en. Les informations ont ainsi été partagées afin de rendre plus aisées la discussion et la sensibilisation entre les détenteurs de savoirs traditionnels et occidentaux, d'accroître les connaissances sur les opinions de la communauté au sujet des changements climatiques et les ressources en eau, et de fixer des stratégies d'action. L'amélioration des politiques et les actions à l’échelle communautaire et individuelle comptent parmi les recommandations formulées et mises en œuvre par la Première nation Stellat'en.

“…Research into ice phenomena occurring in lakes and other water bodies situated in the temperate climate zone covers a broad range of issues. Among the most frequently discussed research problems is the possibility of using long-term ice phenology as an indicator of contemporary climate change [1,5,8,[14][15][16][17][18][19][20][21][22][23][24][25][26][27].…”

Ice phenomena occurring in water bodies are an important indicator of natural changes (e.g., climate change) and the possibilities for economic use of water bodies (e.g., using the ice cover); hence, there is a need to adopt new advanced statistical methods for the purpose of their analysis and assessment. Material for this study was collected for three winter seasons in 39 water bodies in the Silesian Upland (southern Poland). Nine variables were used in the analysis, of which three pertained to the features of the water bodies studied (surface area, mean depth, the amount of water retained), and six pertained patterns to of ice phenomena (average near-surface water temperature during ice phenomena, average and maximum ice thickness, the number of days with ice phenomena, the number of days with ice cover, and average thickness of the snow accumulated on ice). The centroid class principal component analysis (CCPCA) method was found to be the most precise of the five methods used in the study for classifying water bodies in terms of their ice regimes. It enabled the most accurate division of the group of water bodies covered by the study in terms of their ice regimes in conjunction with their morphometric features and hydrological types. The presented method of classifying water bodies using advanced statistical methods is an original proposal, which was used for the first time in limnological research and in the analysis of ice phenomena.

“…Strong links between ice out and winter air temperature have been noted, as well as the influences on ice out dates by a variety of large-scale climatic oscillations ( e.g. , Quasi-Biennial Oscillation (QBO), North Atlantic Oscillation (NAO), El Niño Southern Oscillation (ENSO)) has been recognized ( Livingstone, 2000 ; Magnuson, Benson & Kratz, 2004 ; Bonsal et al, 2006 ; Ghanbari et al, 2009 ; Livingstone et al, 2010 ; Bai et al, 2012 ; Mudelsee, 2012 ; Sharma et al, 2013 ; Fu & Yao, 2015 ; Patterson & Swindles, 2015 ; Imrit & Sharma, 2021 ). However, more robust time series analyses have not yet been widely carried out to verify these oscillations as the drivers of local or regional ice out patterns or to understand the time-varying relationship between ice out and the climate oscillations.…”

Regional impact of large-scale climate oscillations on ice out variability in New Brunswick and Maine

The available ice out (the date of disappearance of ice from a water body) records were analyzed from four relatively closely spaced lakes in southwestern New Brunswick (Harvey, Oromocto, Skiff) and eastern Maine (West Grand Lake), with the longest set of available observations being for Oromocto Lake starting in 1876. Results of a coherence analysis carried out on the ice out data from the four lakes indicates that there is regional coherence and correspondingly, that regional drivers influence ice out. These results also indicate that ice out dates for lakes from the region where records have not been kept can also be interpolated from these results. As the ice out record was coherent, further analysis was done for only Oromocto Lake on the basis of it having the longest ice out record. Cross-wavelet analysis was carried out between the ice out record and a variety of cyclic climate teleconnections and the sunspot record to identify which phenomena best explain the observed ice out trends. The most important observed contributors to ice out were the North Atlantic Oscillation (NAO) and the El Niño Southern Oscillation (ENSO), with observed periodicities at the interannual scale. At the decadal scale the Pacific Decadal Oscillation (PDO) and the 11-year solar cycle were the only patterns observed to significantly contribute to ice out.

A proxy record of winter temperatures since 1836 from ice freeze-up/breakup in lake Näsijärvi, Finland

Abstract: One obstacle on the way to a comprehensive spatial reconstruction of regional temperature changes over the past centuries is the sparseness of long winter temperature records.
