If these billions were made available, they would be far more effectively spent on efforts to rapidly decarbonize. The fourth is the governance arrangements to provide legal oversight and environmental protection for these interventions.

The continent of Antarctica was only discovered a little over 200 years ago, in 1820, by three independent teams from Russia, Great Britain, and the USA. Yet in those two centuries, our knowledge of the frozen continent has expanded enormously, thanks to the use of the latest advances in science and technology, dating back to the earliest years.

ABSTRACTSatellite observations of the Antarctic surface since the 1990s, coupled with geophysical surveys of the flow and form of its giant ice sheet, have revealed accelerating loss of ice to the oceans. This, coupled with a reduction in floating sea ice surrounding the continent and the occurrence of unprecedented heatwaves, point to a continent being changed irreversibly by fossil-fuel burning and the global heating that results.

By Prof Martin Siegert, University of Exeter (Cornwall)42 governments around the world have agreed to protect Antarctica’s environment. While the main focus has been on operational activities in Antarctica, global warming caused by fossil-fuel burning by these (and other) countries has left Antarctica on the brink of irreversible change.
