The Antarctic Peninsula under a 1.5°C global warming scenario.
Warming of the Antarctic Peninsula in the latter half of the 20th century was greater than any other terrestrial environment in the Southern Hemisphere, and obvious cryospheric and biological consequences have been observed. Under a global 1.5°C scenario, warming in the Antarctic Peninsula is likely...
