The warming of mountains has become evident in recent years, with a mean global warming rate of 1.19 °C from 1979 to 2022. However, unveiling the global divergent decline of persistent mountain snow cover in the face of climate shifts remains unexplored. However, the global decline of persistent mountain snow cover due to climate change is not well...

The polar regions have been undergoing amplified warming in recent years. In particular, Greenland has experienced anomalously warm summers with intense melt rates. We employ a surface radiation budget framework to examine the causes for positive and negative summer temperature anomaly events over Greenland from 1979 to 2021. We found a dominant co...

The polar regions have been undergoing amplified warming in recent years. In particular, Greenland experiences a series of hot summers with intense melt rates. By employing a surface radiation budget framework, we examine the causes for extreme summer temperature events over Greenland over the period 1979-2021, considering feedback attribution anal...

The warming of mountainous regions has become evident in recent years with a global average warming rate of 1.41 °C from 1979 to 2022. Our study aims to understand observed changes in snow persistence across mountain regions worldwide, using reanalysis and satellite data. By taking a global perspective, we bridge the gap between regional findings a...

The polar regions have been undergoing amplified warming in recent years. However, natural climate variability can further amplify or dampen the ongoing warming trend causing extreme temperature events. Therefore, it is important to determine the role of climate variability on shaping the characteristics of extreme temperature events. By employing...

Elevation-dependent temperature change is a phenomenon found in mountain regions with complex terrain, mostly in the Himalayas and the high terrain of the Tibetan Plateau, where regions in high elevation feature high rates of warming than the region in lower elevation. This pattern referred to as elevation-dependent warming. However, does elevation...

Mountains become warmer with elevation in response to greenhouse gas warming, an effect known as elevation-dependent warming (EDW). The Eocene is considered a replica of the future climate in an epoch with high atmospheric carbon dioxide concentration (CO2). Therefore, the topographic features of the Eocene strata are of interest. However, obtainin...

The Nioghalvfjerdsfjorden glacier (also known as the 79∘ North Glacier) drains approximately 8 % of the Greenland Ice Sheet. Supraglacial lakes (SGLs), or surface melt ponds, are a persistent summertime feature and are thought to drain rapidly to the base of the glacier and influence seasonal ice velocity. However, seasonal development and spatial...

To get a better overview of atmosphere-driven mass changes at the 79N Glacier (Nioghalvfjerdsfjorden Glacier), the largest outlet glacier of the northeast Greenland ice stream, the surface mass balance (SMB) is modeled by linking the COupled Snowpack and Ice surface energy and mass-balance model in PYthon (COSIPY) with the output of a regional atmo...

Together with two neighbouring glaciers, the Nioghalvfjerdsfjorden glacier (also known as 79 North Glacier) drains approximately 12–16 % of the Greenland ice sheet. Supraglacial lakes (SGLs), or surface melt ponds, are a persistent summertime feature, and are thought to drain rapidly to the base of the glacier and influence seasonal ice velocity. H...

The Indian Ocean dipole mode impacts the atmosphere and hydroclimate in areas surrounding the Indian Ocean. The Coupled Model Intercomparison Project 5 output was used in this study to reveal new aspects of the relationship between the dipole mode and East African “short rains” (occurring from September to November). Furthermore, the impact of huma...
