“…Globally, the size and abundance of glacier lakes has doubled between 1990 and 2017 (Shugar et al., 2020). Most of the growth in glacier lake area has been tied to moraine‐dammed lakes (Buckel et al., 2018; Emmer et al., 2020; Rick et al., 2022; Wilson et al., 2018; Zheng, Allen, et al., 2021), motivating numerous GLOF hazard and risk appraisals (Emmer, 2018). However, our assessment is consistent with other regional assessments that noted a lack of any long‐term, continuous increase in the frequency of moraine‐dam failures (Emmer et al., 2020; Veh et al., 2019).…”

“…To measure annual research interest in GLOFs, we refrained from a bibliometric analysis, as research on GLOFs before 2000 was low: Emmer (2018) found only 170 GLOF research articles listed on the Web of Science between 1979 and 2000. The low publication activity on GLOFs contrasts with the long research tradition on glaciers.…”

“…Shrinking glacier volumes contribute to sea‐level rise, change the freshwater availability in mountain rivers and pose hazards to mountain livelihoods (Huss et al., 2017; Milner et al., 2017; Zemp et al., 2019). Among the most publicized ice‐related hazards are glacier lake outburst floods (GLOFs) (Emmer, 2018). These floods emerge from glacier lakes that store meltwater behind a glacier or moraine dam, or in over‐deepened parts of exposed glacier beds.…”

Trends, Breaks, and Biases in the Frequency of Reported Glacier Lake Outburst Floods

et al. 2022

Thousands of glacier lakes have been forming behind natural dams in high mountains following glacier retreat since the early 20th century. Some of these lakes abruptly released pulses of water and sediment with disastrous downstream consequences. Yet it remains unclear whether the reported rise of these glacier lake outburst floods (GLOFs) has been fueled by a warming atmosphere and enhanced meltwater production, or simply a growing research effort. Here we estimate trends and biases in GLOF reporting based on the largest global catalog of 1,997 dated glacier‐related floods in six major mountain ranges from 1901 to 2017. We find that the positive trend in the number of reported GLOFs has decayed distinctly after a break in the 1970s, coinciding with independently detected trend changes in annual air temperatures and in the annual number of field‐based glacier surveys (a proxy of scientific reporting). We observe that GLOF reports and glacier surveys decelerated, while temperature rise accelerated in the past five decades. Enhanced warming alone can thus hardly explain the annual number of reported GLOFs, suggesting that temperature‐driven glacier lake formation, growth, and failure are weakly coupled, or that outbursts have been overlooked. Indeed, our analysis emphasizes a distinct geographic and temporal bias in GLOF reporting, and we project that between two to four out of five GLOFs on average might have gone unnoticed in the early to mid‐20th century. We recommend that such biases should be considered, or better corrected for, when attributing the frequency of reported GLOFs to atmospheric warming.

“…Hindu Kush Himalayas have been subjected to many glacial lake studies (Emmer, 2018; Fujita et al, 2013; Ives et al, 2010; King et al, 2017, 2018; Maharjan et al, 2018; Schwanghart et al, 2016; Veh et al, 2019), including the ones carried out for specific countries such as Nepal (Mool et al, 2011; Rounce et al, 2017; Somos‐Valenzuela et al, 2015), Bhutan (Komori, 2008; Ukita et al, 2011), and Tibet (Chen et al, 2007; Cui et al, 2011; Wang et al, 2011). Studies carried out for the Indian Himalayas include the work of ICIMOD (Ives et al, 2010) that created a comprehensive glacial lake inventory of Hindu Kush Himalayas and included three Indian states.…”

Indian Himalayas are home to numerous glacial lakes, which can pose serious threat to downstream communities and lead to catastrophic socioeconomic disasters in case of a glacial lake outburst flood (GLOF). This study first identified 329 glacial lakes of size greater than 0.05 km 2 in the Indian Himalayas, and then a remote sensing-based hazard and risk assessment was performed on these lakes. Different factors such as avalanche, rockfall, upstream GLOF, lake expansion, identification of the presence of ice cores, and assessment of the stability of moraine were considered for the hazard modeling. Further, a stochastic inundation model was applied to quantify the potential number of buildings, bridges, and hydropower systems that could be inundated by GLOF in each lake. Finally, the hazard parameters and downstream impact were collectively considered to determine the risk linked with each lake. A total of 23 lakes were identified as very high risk lakes and 50 as high-risk lakes. The potential flood volumes associated with various triggering mechanisms were also measured and were used to identify the lakes with the most considerable risk, such as Shakho Cho and Khangchung Tso. This study is anticipated to support stakeholders and decision-makers in identifying critical glacial lakes and make well-informed decisions related to future modeling efforts, field studies, and risk mitigation measures.

“…Bibliometrics takes quantitative and qualitative analysis, adopts mathematical and statistical methods, and aimed at the distribution of citation counts and the publication of journals and articles as time goes on. [ 3 ] Bibliometrics has been widely applied to various fields including medicine, ecology, geology, etc., [ 4 – 6 ] and has also been employed in the ophthalmic field. For example, in the study of dry eye, Boudry et al [ 7 ] used the VOSviewer software (Leiden, The Netherlands) to execute a bibliometric analysis of dry eye disease on Web of science database, ultimately got the research trends of dry eye, and Schargus et al [ 8 ] have selected studies published in the Institute of Scientific Information database (1900–2016) on dry eye research, offers scholars with a exhaustive analysis on the most cited dry eye literatures, Ramin et al [ 9 ] ran HistCite software (Eugene Garfield, Institute for Scientific Information) to analyze 20 years of glaucoma research, Caglar et al [ 10 ] resorted to the correlation analysis in routine statistics to find out the rule of diabetic retinopathy paper from 1980 to 2014.…”
