Northward expansion of the thermal limit for the tick Ixodes ricinus over the past 40 years Open
Background The sheep tick Ixodes ricinus is the vector associated with the highest incidence of vector-borne disease in humans in Europe. Several studies have been published about the effect of future climate change on the potential distri…

Observation error estimation in climate proxies with data assimilation and innovation statistics Open
Data assimilation (DA) has been successfully applied in paleoclimate reconstruction. DA combines model simulations and climate proxies based on their error sizes. Therefore, error information is crucial for DA to work optimally. However, l…

Dynamical reconstruction of Southern Ocean and Antarctic climate variability since 1700 Open
Understanding long-term climate variability in the high latitudes of the Southern Hemisphere is critical due to the key role of the Southern Ocean in the global climate system. However, sparse observations (in space and time) coupled with …

Recent intensification of extreme precipitation over Antarctica driven by increases in greenhouse gases Open
Extreme precipitation is a major contributor to the total precipitation over Antarctica, as well as its variability. However, it's still poorly understood whether any recent trends in extreme precipitation over Antarctica have occurred, an…

Contribution of ocean processes to the drops in Antarctic sea ice extent at the end of the 1970s and after 2 Open
The Antarctic sea ice extent has displayed two large drops over the past 65 years, a small one at the end of the 1970s and a more substantial one after 2016. The atmospheric forcing provided a dominant contribution to those drops. Wind cha…

Towards an improved understanding of Pacific Decadal Variability using paleoclimate reanalysis Open
The Pacific Decadal Variability (PDV) is the dominant mode of Earth System variability on multi-decadal timescales. Depending on the phase of the PDV, it can either accelerate or mitigate the global warming trend. Additionally, PDV has sig…

Extending our knowledge of Antarctic SMB further back in time Open
The reconstruction of Antarctic surface mass balance (SMB) is essential for understanding ice sheet dynamics and sea level rise, yet existing datasets are limited to the satellite era (1979-present) because little is known about the sea su…

Northward expansion of the thermal limit for the tick Ixodes ricinus over the past 40 years Open
The tick Ixodes ricinus is the main pathogen vector in Europe. Many speculations have been made about the effect of past climate change on the potential distribution of this ectothermic organism, despite a poor understanding of how climate…

Role of precipitation and extreme precipitation events in the surface mass balance variability observed in three ice cores from coastal Dronning Maud Land Open
The Antarctic Ice Sheet (AIS) is the most uncertain contributor to future sea level rise for projections by the end of this century. One of the main drivers of future AIS mass changes is the surface mass balance (SMB) of the ice sheet, whi…

Brief Communication: annual large-scale atmospheric circulation reconstructed from a data assimilation framework cannot explain local East Antarctic ice rises’ surface mass balance records Open
Ice cores are influenced by local processes that alter surface mass balance (SMB) records. To evaluate if large-scale atmospheric circulation explains contrasted SMB trends at eight East Antarctic ice rises, we assimilated ice core SMB rec…

Multi‐Decadal Variability of Amundsen Sea Low Controlled by Natural Tropical and Anthropogenic Drivers Open
A crucial factor influencing the mass balance of the West Antarctic Ice Sheet is the Amundsen Sea Low (ASL), a climatological low‐pressure region situated off the West Antarctic coast. However, albeit the deepening of the ASL since the 195…

What was the contribution of the ocean to the 2016 Antarctic sea ice extent drop and was this event unprecedented? Open
The 2016 Antarctic sea ice extent drop was a rapid decline that led to persistent low sea ice conditions. The drop followed a period of stability and even slight sea ice extent increase: this sudden change from extreme high values to an ab…

Intensifying circumpolar winds contributes to reducing winter Antarctic sea ice growth Open
During the austral autumn/winter of 2023 Antarctic sea ice exhibited a pan-Antarctic wide delay in refreezing of roughly a month (peaked in July 2023, hereafter referred to as W23 event). As such it is unprecedented over the satellite era …

Reconstructing historical ocean changes around the West Antarctic Ice Sheet over the past centuries Open
Over recent decades, the West Antarctic Ice Sheet (WAIS) has witnessed a large increase in ice shelf melting. This ice loss is recognized to be associated with a response to changes in the ocean state, in particular of the Circumpolar Deep…

Origin of the trends in Antarctic sea ice extent over the period 1958-2023  Open
The Antarctic sea ice extent has displayed several regime shifts over the past 65 years. Consistent lines of evidence indicate a decline in Antarctic sea ice extent from 1958 to 1978, which precedes the availability of continuous satellite…

A comparison of South Pacific Antarctic sea ice and atmospheric circulation reconstructions since 1900 Open
The recent changes and record lows in Antarctic sea ice extent illustrate the need for longer estimates beyond the short satellite observation period commencing around 1979. However, Antarctic sea ice extent reconstructions since 1900 base…

An Unprecedented Sea Ice Retreat in the Weddell Sea Driving an Overall Decrease of the Antarctic Sea‐Ice Extent Over the 20th Century Open
Sea‐ice extent is predicted to decrease in a warming climate. However, despite global warming over the past century, total Antarctic sea ice remained relatively stable from 1979 until 2015, before strongly melting. Here we explore the long…
