Short summary
Short summary
Aquatic vegetated ecosystems are important for global carbon sequestration, but freshwater shorelines remain understudied. We found that the sedimentary organic carbon (SOC) stocks ranged from 0 to 40.8 kg m−2, with a large spatial variability. Large SOC stocks were found in sheltered areas, with the predominance of fine-grained sediments. In exposed areas, vegetation might also impact SOC accumulation. Accounting for shoreline exposure is crucial for improving regional carbon budget estimates.

This study explores the climate impact of reduced Antarctic and Greenland ice sheets using the Late Pliocene as an analogue for future climate. Results reveal a 9.5 °C rise in Antarctic surface temperature, 16 % sea ice loss, a less stable westerly jet, and a weakened Antarctic Bottom Water formation. By isolating albedo effects, this research provides insights into global climate dynamics and feedbacks.

We present a reconstruction of permafrost and snow cover on the British Isles for the Younger Dryas period, a time of extremely cold winters that happened approximately 12 000 years ago. Our results indicate that seasonal sea ice in the North Atlantic was most likely a crucial factor to explain the observed climate shifts during this time.

Lake Petén Itzá, northern Guatemala, is one of the oldest lakes in the northern Neotropics. In this study, we analyzed geochemical and mineralogical data to decipher the hydrological response of the lake to climate and environmental changes between 59 and 15 cal ka BP. We also compare the response of Petén Itzá with other regional records to discern the possible climate forcings that influenced them. Short-term climate oscillations such as Greenland interstadials and stadials are also detected.

Using climate model simulations, we find that SE Asian tropical climate was strongly seasonal under Late Glacial conditions. During Northern Hemisphere winters, it was highly arid in this region that is today humid year-round. The seasonal aridity was driven by orbital forcing and stronger East Asian winter monsoon. A breakdown of deep convection caused a reorganized Walker Circulation and a mean state resembling El Niño conditions.

Short summary
In this study, we analysed 14 sea-ice proxy records and compared them with the results from two different climate simulations from the Atlantic sector of the Arctic Ocean over the Common Era (last 2000 years). Both proxy and model approaches demonstrated a long-term sea-ice increase. The good correspondence suggests that the state-of-the-art sea-ice proxies are able to capture large-scale climate drivers. Short-term variability, however, was less coherent due to local-to-regional scale forcings.
In this study, we analysed 14 sea-ice proxy records and compared them with the results from two...
