Climate change poses greatest threat to Antarctica

The report found that, like elsewhere in Australia, climate change is a key driver of change in Antarctica, the sub-Antarctic and the Southern Ocean. Pollution, tourism, commercial fishing, and an expanding human presence, also affect the Antarctic region.

Monitoring temperature trends in Antarctica using GPS radio

Global Positioning System (GPS) receiver, will use radio occultation (RO) limb sounding technology to profile the Earth''s atmosphere with unprecedented accuracy and vertical resolution. The GPS RO soundings available from COSMIC will make significant contributions to global weather prediction, ionospheric research, and climate monitoring.

13 Feet of Sea Level Rise? Scientists Hunt Clues Beneath Antarctic Ice

6 小时之前· Scientists are studying the West Antarctic Ice Sheet to understand its response to warming and predict future sea-level rise. An international team of scientists, including faculty

Antarctic ice is disappearing, threatening massive sea level rise

West Antarctica is headed for decades of rapid melting no matter how quickly humans cut greenhouse gas emissions, and 2023 shattered records for missing sea ice around the continent.

Understanding Antarctica''s contribution to sea level rise

If the AIS were to completely melt, global sea levels would rise by about 58 metres. The huge East Antarctic Ice Sheet (covering two thirds of the continent) would contribute about 52 metres of this sea-level rise, while the West Antarctic Ice Sheet and the Antarctic Peninsula would make up the rest.

Sustained greening of the Antarctic Peninsula observed from

The Antarctic Peninsula has experienced considerable anthropogenic warming in recent decades. While cryospheric responses are well defined, the responses of moss-dominated terrestrial ecosystems...

13 Feet of Sea Level Rise? Scientists Hunt Clues Beneath Antarctic

6 小时之前· Scientists are studying the West Antarctic Ice Sheet to understand its response to warming and predict future sea-level rise. An international team of scientists, including faculty from Binghamton University, State University of New York, is embarking on an ambitious mission to gather critical geological records from the West Antarctic Ice Sheet.

The influence of realistic 3D mantle viscosity on

To capture lateral variations in Earth structure, we combine the most recent seismic and geodetic records in Antarctica (26, 28, 29, 31) with a global seismic tomography model to build a global 3D model of Earth''s mantle

Antarctic and global climate history viewed from ice cores

The data show tight links among greenhouse gases, aerosols and global climate on many timescales, demonstrate connections between Antarctica and distant locations, and reveal the extraordinary...

Future climate response to Antarctic Ice Sheet melt

Meltwater and ice discharge from a retreating Antarctic Ice Sheet could have important impacts on future global climate. Here, we report on multi-century (present–2250) climate simulations performe...

Record-high Antarctic Peninsula temperatures and surface melt in

The Antarctic Peninsula (AP) experienced a new extreme warm event and record-high surface melt in February 2022, rivaling the recent temperature records from 2015 and 2020, and contributing to...

The influence of realistic 3D mantle viscosity on Antarctica''s

To capture lateral variations in Earth structure, we combine the most recent seismic and geodetic records in Antarctica (26, 28, 29, 31) with a global seismic tomography model to build a global 3D model of Earth''s mantle viscosity and lithospheric thickness with 3-km spatial resolution beneath key areas of ice loss in Antarctica (Fig. 2; see
