Distribution-informed machine learning for flash flood susceptibility: integrating weibull extreme value theory with interpretable models
Abstract Flash floods represent one of the deadliest weather-related hazards globally, yet their prediction remains fundamentally challenged by extreme class imbalance in observational data. This study addresses a critical methodological gap: traditional evaluation metrics, both overall accuracy and Area Under the ROC Curve (AUC), are systematically misleading for rare event prediction.
Cordilleran Ice Sheet early deglaciation inferred from evolution of Late‐Pleistocene glacial Lake Dzulh Stun in east‐central British Columbia, Canada
Introduction The Cordilleran Ice Sheet blanketed much of the northwest of North America several times during the past 3 million years (Clague, 1989; Jackson and Clague, 1991). At its maximum, the ice sheet and its satellite glaciers covered almost all of British Columbia (BC), as well as southern Yukon Territory, southern Alaska, and northern Washington, Idaho, and Montana. At this time, it was up to 1900 km long, 900 km wide, and up to 3000 m thick (Wilson et al., 1958).

How Canada and the U.S. Can Still Tackle Climate Change in a Second Trump Era
U.S. President Donald Trump has once again withdrawn the United States from the Paris agreement on climate change. There is a palpable sense of fear among environmentalists and those concerned about climate change following Trump’s re-election. His “drill baby drill” support for fossil fuels in the U.S. and frequent criticisms of renewable energy suggest that the world can expect to see a U.S. government that is far less interested in addressing climate change.

The development of terrestrial ecosystems emerging after glacier retreat - Nature
|
Abstract The global retreat of glaciers is dramatically altering mountain and high-latitude landscapes, with new ecosystems developing from apparently barren substrates1,2,3,4. The study of these emerging ecosystems is critical to understanding how climate change interacts with microhabitat and biotic communities and determines the future of ice-free terrains1,5.

Study of a Steady-State Landscape Using Remote Sensing and Topographic Analysis
Abstract : The current limited approaches to calculating hillslope erosion rate hamper the study of the relationships among the rates of hillslope erosion, river incision, and tectonic uplift and hence the discussion of steady-state landscape evolution. In this paper, we use remote sensing and geochronological methods to calculate the upper and lower bounding hillslope erosion rates in the Qilian Shan range, Tibet.

Volume 59 • Number 11 • November 2022 Landscape and Seascape Responses to Canada's Changing Climate Introduction Articles Vol. 59No. 11pp. 759–771 Ground ice distribution and abundance have wide-ranging effects on periglacial environments and possible impacts on climate change scenarios. In contrast, very few studies measure ground ice in the High Arctic, especially in polar deserts and where coarse surficial material complicates coring operations.
Meighen Ice Cap: changes in geometry, mass, and climatic response since 1959
Loss of accumulation zone on MIC The decadal scale Equilibrium Line Altitude (ELA; the theoretical line of zero mass balance that separates the zone of accumulation above, from the zone of ablation below) was estimated as the altitude (x axis) of the zero intercept of bn (y axis) plotted as a linear trend line through in situ stake values averaged for each decade throughout the 56-year period of this study (Fig. 10).
How an ‘atmospheric river’ drenched British Columbia and led to floods and mudslides
Recommended for you… Flood waters cover highway 1 in Abbotsford, B.C., on Nov. 16, 2021. THE CANADIAN PRESS/Jonathan Hayward The West Coast of Canada is known for its wet autumn weather, but the storm that British Columbia’s Fraser Valley experienced recently was one for the record books.

Canada's diverse landscape speaks to its fascinating geological history, from towering peaks to Prairie plains, from fertile farmlands of the Great Lakes and St. Lawrence Lowlands to rugged cliffs of the Atlantic shore. However, the modern landscape is just the latest episode in an epic story spanning more than 4 billion years.
Inondations et glissements de terrain en C-B : les effets d’une " rivière atmosphérique "
La côte ouest est réputée pour ses automnes pluvieux, mais la tempête qui s’est abattue sur la vallée du Fraser en Colombie-Britannique ce week-end a brisé plusieurs records. Pendant deux jours, un système météorologique appelé « rivière atmosphérique », accompagné de forts vents et de pluies diluviennes, a traversé la partie sud-ouest de la province, provoquant des dommages importants et la mort d’une personne.
The science behind the ‘atmospheric river’ that drenched British Columbia | The Narwhal
The West Coast of Canada is known for its wet autumn weather, but the storm that British Columbia’s Fraser Valley experienced over the weekend was one for the record books. A weather system called an “atmospheric river” flowed across the southwest corner of the province and, over a period of two days, brought strong winds and near-record amounts of rain, which caused widespread flooding and landslides. So far, one person has died.

Reconstruction of isostatically adjusted paleo-strandlines along the southern margin of the Laurentide Ice Sheet in the Great Lakes, Lake Agassiz, and Champlain Sea basins
Summary and conclusions We compiled published strandline data, consisting of strandline elevation and position measurements (in metres above sea level and geographic location in decimal degrees), based on accurate instrumental surveys published during the past 120 years of major paleo-lakes and a paleo-sea along the southern margin of the LIS for Lake Agassiz, the Great Lakes, upper St. Lawrence River, and Lake Champlain valleys.
Postglacial sea-level lowstand on Cumberland Peninsula, Baffin Island, Nunavut
Depositional history and chronology The discovery and bathymetric mapping of submerged shore features confirms the Holocene submergence and transgression of eastern Cumberland Peninsula; however, these landforms cannot provide sea-level index points for the RSL history of the region without depositional ages. Delta formation is related to sediment supply and meltwater discharge from valley glaciers and therefore can be related to the deglacial chronology.
Landfast ice properties over the Beaufort Sea region in 2000-2019 from MODIS and Canadian Ice Service data
Discussion and conclusions Despite a long history of operational LFI mapping, some important issues related to detailed accuracy and climatology of the LFI in the Beaufort Sea region remain to be addressed.

Influence of a large debris flow fan on the late Holocene evolution of Squamish River, southwest British Columbia, Canada
Cheekye Fan is a large paraglacial debris flow fan in southwest British Columbia. It owes its origin to the collapse of Mount Garibaldi, a volcano that erupted in contact with glacier ice near the end of the Pleistocene Epoch. The fan extended across Howe Sound, isolating a freshwater lake upstream of the fan from a fjord downstream of it. Squamish River built a delta into this lake during the Holocene.
River piracy and drainage basin reorganization led by climate-driven glacier retreat
To provide insight into the evolution of regional drainage, we produced structure-from-motion digital elevation models (SfM DEM) of the proglacial environment of Kaskawulsh Glacier from drone (DJI Phantom 3 Pro) and helicopter imagery, using a Trimble R10 real-time kinematic Global Navigation Satellite System (RTK-GNSS) to establish ground control points and survey lake outlet elevations.

bDepartment of Geography and the Environment, University of the Fraser Valley, 33844 King Road, Abbotsford, BC V2S 7M8, Canada. Sea cliffs at Cape Ball on Graham Island, British Columbia, expose a thick sequence of Pleistocene sediments deposited during at least two glaciations. In sequence, from the base of the section, the units are (1) stony mud, (2) till, (3) silt, sand, and peat, (4) stony mud, (5) laminated sand and silt, (6) cross-bedded sand, and (7) till.
The “Art of Being Alone”
As a tween I was enthralled with the book My Side Of The Mountain by Jean Craighead George. The idea of living in the woods by myself seemed romantic and adventuresome. Not having to account for my actions was appealing. Living off the land and communing with nature was something I could connect with, at least in my fantasy world.
Rocky Mountain Trench
Article by John J. Clague, Michael Wilcox The Rocky Mountain Trench is a long and deep valley extending approximately 1,500 km from the Bitterroot Valley in northwest Montana through British Columbia to the Liard Plain just south of the Yukon Territory. Its predominantly flat floor is 3–20 km wide and ranges in elevation between 600 m and 1,000 m above sea level.
