Sharing Our Knowledge
Sharing Our Knowledgebrings together Native elders, tradition bearers, educators, cultural activists, anthropologists, linguists, historians, and museum professionals to explore the culture, history, and language of the Tlingit people of southeast Alaska and their coastal neighbors. These interdisciplinary, collaborative essays present Tlingit culture, as well as the culture of their coastal neighbors, not as an object of study but rather as a living heritage that continues to inspire and guide the lives of communities and individuals throughout southeast Alaska and northwest British Columbia.
This volume focuses on the preservation and dissemination of Tlingit language, traditional cultural knowledge, and history from an activist Tlingit perspective.Sharing Our Knowledgealso highlights a variety of collaborations between Native groups and individuals and non-Native researchers, emphasizing a long history of respectful, cooperative, and productive working relations aimed at recording and transmitting cultural knowledge for tribal use and promoting Native agency in preserving heritage. By focusing on these collaborations, the contributors demonstrate how such alliances have benefited the Tlingits and neighboring groups in preserving and protecting their heritage while advancing scholarship at the same time.

Impact of North Pacific Meridional Mode Diversity on Western North Pacific Tropical Cyclone Genesis
This study investigates the diversity of the impact of the North Pacific Meridional Mode (NPMM) on western North Pacific (WNP) tropical cyclone (TC) genesis during June–November from 1961 to 2024. We consider preceding springtime NPMM events driven by tropical and extratropical forcings, and classify them as successive and stochastic events, respectively. In successive positive NPMM years, TC genesis changes only slightly over the entire WNP. In successive negative NPMM years, significant increases (decreases) in TC genesis are observed over a region spanning 20°–140°E, 0°–20°N (140°–160°E, 0°–20°N). In stochastic NPMM years, there are significant increases in TC genesis over a region spanning 135°–160°E, 5°–25°N. These changes in TC genesis can be explained by the anomalous environmental conditions in different NPMM years, which can be further linked to the NPMM's strength as well as sea surface temperature anomalies over the tropical western Pacific.

Differential Credibility of Climate Modes in CMIP6
This work quantitatively evaluates the fidelity with which the northern annular mode (NAM), southern annular mode (SAM), Pacific–North American pattern (PNA), El Niño–Southern Oscillation (ENSO), Pacific decadal oscillation (PDO), Atlantic multidecadal oscillation (AMO), and the first-order mode interactions are represented in Earth system model (ESM) output from the CMIP6 archive. Several skill metrics are used as part of a differential credibility assessment (DCA) of both spatial and temporal characteristics of the modes across ESMs, ESM families, and specific ESM realizations relative to ERA5. The spatial patterns and probability distributions are generally well represented but skill scores that measure the degree to which the frequencies of maximum variance are captured are consistently lower for most ESMs and climatemodes. Substantial variability in skill scoresmanifests across realizations fromindividual ESMs for the PNA and oceanic modes. Further, the ESMs consistently overestimate the strength of the NAM–PNA first-order interaction and underestimate the NAM–AMO connection. These results suggest that the choice of ESMand ESM realizations will continue to play a critical role in determining climate projections at the global and regional scale at least in the near term.
SIGNIFICANCE STATEMENT: Internal climate variability occurs over multiple spatial and temporal scales and is encapsulated in a series of internal climate modes. The representation of such modes in climate models is a critically important aspect of model fidelity. Analyses presented herein uses several skill scores to evaluate both the spatial and temporal manifestations of these climate modes in the CMIP6 generation of Earth system models (ESMs). There is marked variability in model fidelity for these modes and this variability in credibility within the current climate has important implications for the choice of specific ESMs and ESM realizations in making climate projections.

Not fit to stay : public health panics and South Asian exclusion
\"Not Fit to Stay: Public Health Panics and South Asian Exclusion examines how and why South Asians were prevented from immigrating to British Columbia, Washington, Oregon, and California between 1900 and 1920. In the first decades of the twentieth century, all Asian immigrants to Canada and the United States faced opposition to their arrival and settlement. While racism and fear of labour competition were at the heart of this resistance, panic soon swept up and down the West Coast of North America over unsubstantiated public health concerns. Public leaders--including physicians, union leaders, civil servants, journalists, and politicians--latched on to these health concerns as the basis for the exclusion of the South Asians, who were said to suffer from medical conditions and diseases attributed to their race. Even though many officials knew the public health argument had no grounds, they promoted it to support their racist views and concerns about labour. Legislation to restrict the immigration of South Asians took effect in Canada in 1908 and in the United States in 1917. This book is an important study of how white North Americans saw first-wave South Asian immigrants as separate from, and inferior to, other groups in the evolving racial hierarchy on the West Coast of North America.\"-- Provided by publisher.

Role of the Aleutian Low in Modulating the Connection between the Moderate El Niño and the Following Spring North Tropical Atlantic SST Anomalies
El Niño events are likely to be followed by significant positive sea surface temperature anomalies (SSTAs) over the north tropical Atlantic (NTA). We find that this is not always true for El Niño with moderate intensity. Nearly half of the moderate El Niño cases are followed by the strong NTA SSTAs, but others are followed by the weak NTA SSTAs, indicating the uncertainty in the connection between the moderate El Niño and the NTA. The differences in the El Niño–related NTA SSTAs are due to the different extratropical teleconnection between El Niño and the NTA, manifesting as a Pacific–North American (PNA) pattern. Further analysis suggests that the deepened Aleutian low (AL) induces the negative North Pacific SSTA, which is associated with a wave train propagating eastward, and, modulates the El Niño–generated PNA pattern. Therefore, El Niños that are accompanied by the strong AL induce a strong PNA pattern that, in turn, leads to the strong NTA SSTAs. The strength of the AL coinciding with El Niño plays a crucial role in modulating the connection between the moderate El Niño and the NTA SSTAs. This observational evidence about the uncertainty in the El Niño–NTA connection and the role of the AL in modulating this connection is further supported by the model simulations that participated in phase 6 of the Coupled Model Intercomparison Project (CMIP6). These results indicate that the combined effects of El Niño and the AL must be considered to fully understand the NTA SSTA variability.

Asymmetric impacts of El Niño and La Niña on the Pacific–North American teleconnection pattern: the role of subtropical jet stream
The asymmetric impacts of El Niño and La Niña on the Pacific–North American teleconnection pattern in boreal winter have important implications for the surface air temperature and precipitation anomalies in North America. Previous studies have shown that the varying tropical convective heating contributes to the zonal shift of the teleconnection pattern during different El Niño/Southern Oscillation phases. In this study, using reanalysis, atmospheric general circulation model (AGCM) simulations, and a linear baroclinic model, we further present that the discrepancy of the subtropical jet stream (STJ) during El Niño and La Niña also contributes to the asymmetry. The atmospheric anomalies readily extract kinetic energy and effectively develop at the exit of the STJ. During El Niño (La Niña) years, as the central-eastern tropical Pacific warms up (cools down), the meridional temperature gradient in central subtropical Pacific increases (decreases), leading to the eastward (westward) shift of the STJ. The movement of the STJ leads to the shift of the location where disturbance develops most efficiently, ultimately contributing to the asymmetry of the teleconnection pattern.
