100 Mind-Blowing Essential Facts

Antarctica is home to the largest ice sheet on Earth. More than six times as large as Greenland, Antarctica is the southernmost continent and is the coldest and windiest place on Earth – with temperatures that can drop as low as -89.2°C and winds that can exceed 320 km per hour. Antarctica is home to the largest ice sheet on Earth, containing a staggering 30 million cubic kilometres of ice. This represents an incredible 70% of Earth’s freshwater and 90% of its ice. As a result, changes to the Antarctic ice sheet can have significant implications for global sea levels and ocean currents. Monitoring the Antarctic ice sheet is therefore of paramount importance and satellite data plays a crucial role in this effort. Data from satellites such as CryoSat, ESA’s ice mission, allow scientists to track changes in the thickness and movement of the ice sheet over time, providing insights into how it is responding to a changing climate. ESA has recently teamed up with NASA and the British Antarctic Survey (BAS) to carry out an ambitious campaign in Antarctica which involved taking simultaneous measurements of sea ice from ESA’s CryoSat and NASA’s ICESat-2 satellites. This research is essential for informing policy decisions on issues such as climate change and sea level rise, and for developing strategies to mitigate their impact on coastal communities around the world.
