Abstract In recent decades, temperature variations have significantly affected the ecosystem and human livelihood in Pakistan. The wavelet analysis is employed to identify associations between regional change global teleconnections, i.e. Atlantic Multidecadal Oscillation (AMO), Arctic (AO), North (NAO), El Niño–Southern (ENSO), Pacific Decadal (PDO), Tropical Northern Index (TNA), Pacific/North American (PNA), Pattern (NP), Western (WP), Hemisphere Warm Pool (WHWP). This paper first uses monotonic modified Mann–Kendall Sen’s slope estimator compute changes Pakistan its homogenous climatic regions during 1960–2020. It found that has increased at 0.23 °C dec −1 last 62 years, which also higher than average increase. increase more evident region IV V spring 0.63 0.43 respectively, followed by summer autumn. Temperature sub-regions are mainly associated with NP, WP WHWP mean significant coherences. Overall, influenced multiple interactions of these combinations indicate integrated influence teleconnections can better explain changes. broader over NP + WHWP, Pacific-based (ENSO, PDO, PNA), Atlantic-based (AMO, AO, NAO) indices as revealed coherences 0.82, 0.82 0.72 respectively. Annually, AMO, TNA showed correlation magnitudes 0.44, 0.42 0.20 indicating modulation effect on combined impacts from various represent a considerable advancement accuracy country. These findings implications for policymakers terms planning policies light climate well atmospheric circulation variability.

Over the last two decades, urban floods and their impacts have been on rise worldwide, owing to both climatic changes human activities. The present study examines different at-risk elements, such as residential, commercial, critical facilities, evaluate multi-components of vulnerability in Peshawar, Pakistan. Based floods, weightage each component for selected elements at risk is defined. This presents uses modified Fisher's ideal quantity index combine components into a single value. Additionally, Patnaik Narayan employed generalize sector-wise vulnerabilities across area. results show that old physical infrastructure commercial manufacturing units Kohati Gate area highly vulnerable while residential are least susceptible due distanced location from drainage system. In Hayatabad, encroachments along torrent's sides, affecting housing educational institutions, contributed increased despite relatively lower vulnerability. provides new platform understanding tackling challenges posed by effectively.

Tatra Mountains, Western Carpathians Our study aims to assess the impact of climatic changes on streamflow in headwater mountain catchments with varying human pressure. The research bases hydrological and climatological data from a period 1971–2020 includes trend analysis, wavelet analysis paired catchment observations, comparing semi-natural human-altered catchments. Air temperature has increased (+0.4°C decade−1) region. Precipitation totals remained unchanged, however annual snowfall decreased (−69 mm decade−1, ∼6.3%) at expense rainfalls, especially winter. precipitation exhibited altitude-dependent changes. Snow depths stable; however, snow cover duration shortened (−2 −4 days decade−1). observed have led an increase low flows (+7–11.5% decade−1), as well winter low, average, high flows, affecting timing snowmelt runoff. Streamflow were more pronounced Climatic-driven trends evident winter, whereas associated activities land use detected throughout year. Discharge was coherent catchments, weaker intensification cycle semiannual altitudes, along streamflow, provide evidence ongoing

Abstract Elevation‐dependent warming (EDW) has been a topic of intense debate due to limited observed data in global highland areas. This study aims fill this gap by utilizing CRU and ERA5 datasets from 1981 2021 explore the trends climate change its elevation dependency. The anomalies temperature indicators ( T mean , max min ) both showed significant over highlands. Moreover, response across highlands is not spatially uniform. linear regression model based on signals for at various elevations On regional scale, predominantly EDW EU highlands, while Asian exhibited 4–5 km. 2.5–5.5 km with 3–5 CRU. In Andes, was prominent 2.5–4 Overall, are evident all studied regions but vary them. While assessing driving factors, results indicate that total column water vapour (TCWV), snow depth (SD), albedo, normalized difference vegetation index (NDVI) correlated positively indicators. These findings emphasize significance elevation‐specific interactions between environmental factors forecasting changes mountainous Additionally, coherence teleconnection indices Atlantic Pacific Oceans. European (EU) interzonal Oceans, North American (NA) coherence, followed South (SA) provide comprehensive understanding implications globally, including potential more severe depletion snow/ice resources warmer future.
