Climate Science
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.
Human activity has driven retreat of one of Antarctica’s most important glaciers British Antarctic Survey scientists have contributed to the first study to directly link the retreat of a major Antarctic glacier to human-caused climate change. The post Human activity has driven retreat of one of Antarctica’s most important glaciers appeared first on British Antarctic…
The West Antarctic Ice Sheet (WAIS) has undergone rapid change over the satellite era, characterized by significant thinning, grounding-line retreat, and mass loss. More than a third of the ice […] The post Detection and attribution of the role of anthropogenic climate change in industrial-era retreat of Pine Island Glacier appeared first on British Antarctic…
This review considers the current status, and highlights existing knowledge gaps, on Antarctic terrestrial and freshwater biological responses to climate change. Climate change is considered to be one of the […] The post Antarctic terrestrial and freshwater biological responses to climate change appeared first on British Antarctic Survey.
Natural disturbance events are expected to increase with climate change. This is particularly evident in polar regions where reduced winter sea-ice has increased movement of icebergs, and thus seafloor scouring. […] The post Shallow benthic Antarctic food webs recover complexity after disturbance appeared first on British Antarctic Survey.
Climate change driven release of methane (CH4) from polar and sub-polar sediments could accelerate global warming, and tracking CH4 in cold sediments over geological time helps predict future releases. Isotopic […] The post Ikaite precipitation indicates near surface occurrence of methane in an Icelandic fjord appeared first on British Antarctic Survey.
Antarctic, Southern Ocean, and Global Ocean Temperatures during Dansgaard–Oeschger Events [preprint]
Global Mean Ocean Temperature (GMOT) changes are thought to be both an important consequence and a possible cause of Dansgaard-Oeschger (DO) events, a series of abrupt climate changes during the […] The post Antarctic, Southern Ocean, and Global Ocean Temperatures during Dansgaard–Oeschger Events [preprint] appeared first on British Antarctic Survey.
