Subglacial sedimentary basins in Antarctica are hypothesized to modulate ice flow and biogeochemical cycles via groundwater and geothermal feedbacks, yet their properties remain poorly constrained. Here, we present a joint […] The post Distinct Groundwater Regimes in West Antarctic Sedimentary Basins Inferred From Magnetotelluric Imaging appeared first on British Antarctic Survey.
Emperor penguins are threatened by climate change and their population is predicted to decline rapidly this century due to changes in Antarctic sea ice. Remote sensing is a key tool […] The post Year-round movement of emperor penguin colonies observed from space appeared first on British Antarctic Survey.
Register here if attending online This lecture argues that temporal strategies, arguments, and contestations are fundamental dimensions of the current struggle for climate reparations. Demands for reparatory climate justice seek to challenge international law’s temporal abstractions and its progressive linear temporality, while redefining the boundaries of established legal doctrines. These efforts invite to take seriously…
Southern Hemisphere (SH) circulation and surface climate changes are emerging in recent decades. For example, in most seasons, the SH Hadley cell edge and the eddy-driven jet stream have shifted […] The post Disentangling Anthropogenic Effects on Southern Hemisphere Circulation and Surface Climate: A Multi‐Model Large Ensemble Approach appeared first on British Antarctic Survey.
Changes in sea ice concentration (SIC) and derived sea ice extent have been monitored using microwave radiometers since the late 1970s, providing information about the polar response to climate change, […] The post Sensitivity of the Bootstrap sea ice concentration algorithm to surface parameters in the Antarctic marginal ice zone using passive microwave retrievals appeared…
Climate change is driving vegetation expansion in polar regions. Roland et al.1 report a 14-fold greening trend across the Antarctic Peninsula region since the 1980s, based on satellite data. However, […] The post Greening rates are sensitive to methodology and biology; comment to Sustained greening of the Antarctic Peninsula observed from satellites [Commentary] appeared first…
During Pleistocene ice ages, abrupt climate changes co-occurred with switches in Atlantic Meridional Overturning Circulation (AMOC) strength. The global impact and characteristic north-south temperature pattern of these events is typically […] The post Planetary energy budget during abrupt glacial climate events set by Atlantic Ocean heat valve appeared first on British Antarctic Survey.
Wildfires are becoming increasingly frequent and intense under ongoing climate change, with the potential to emit and transport particles, from black carbon to nutrient-bearing aerosols, into remote and fragile ecosystems […] The post Arctic transport of North American and Canadian wildfire aerosols appeared first on British Antarctic Survey.
Climate change has dramatically altered the Arctic seas with significant decrease in sea ice extent and thickness and warming water temperature. The ecological impacts of such change have been described […] The post A pan-Arctic pigment database for phytoplankton and sea-ice algae appeared first on British Antarctic Survey.
Snow algae are important primary producers in Antarctic terrestrial ecosystems. As short-term Antarctic summer temperatures approach 20°C, parameterising temperature tolerance for snow algal species is key to determining how climate […] The post Antarctic snow algal responses to temperature – potential implications of climate change appeared first on British Antarctic Survey.
