Climate Science
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.
Extreme environmental events (EEEs) in Antarctica and the Southern Ocean are occurring with growing frequency and severity, and will become more pronounced under continued global warming. Antarctic research relies on […] The post Antarctic science operations must account for climate change and extreme environmental events appeared first on British Antarctic Survey.
Climate change is reshaping contaminant pathways in Antarctica by mobilizing rare earth elements (REEs) and heavy metals from the cryosphere into marine ecosystems. Thaw-driven changes in salinity, pH, stratification, and […] The post Climate-Driven Mobilization of Rare Earth Elements and Metals in Antarctica: Pathways, Ecological Exposure, and Implications for Trophic Transfer appeared first on British…
Ecological roles, climate-driven responses, and critical knowledge gaps of krill in the global ocean
Human-induced global climate change and other anthropogenic stressors are fundamentally altering our oceans. Understanding the ecological and societal implications of these changes is critical for developing mitigation strategies and conservation […] The post Ecological roles, climate-driven responses, and critical knowledge gaps of krill in the global ocean appeared first on British Antarctic Survey.
Increasing human activity and climate change in Antarctica may increase the rates of non-native species introduction and establishment, resulting in potentially irreversible changes in marine and terrestrial ecological communities. The […] The post Grass is not always greener: enablers and barriers of non-native species governance and management in Antarctica appeared first on British Antarctic Survey.
