The phenomenon of warming being more pronounced in the Arctic than the Antarctic is often referred to as Arctic amplification. There are several reasons for this:

Ice-Albedo Feedback: The Arctic has seen significant melting of sea ice. As ice melts, it exposes darker ocean water, which absorbs more solar radiation, leading to more warming and more ice melt. This positive feedback loop is known as the ice-albedo effect. The Antarctic, on the other hand, is a large landmass covered by a thick layer of ice, and much of the sea ice that forms in the winter melts in the summer, so this feedback loop isn't as strong.

Geography and Ocean Currents: The Arctic is an ocean surrounded by land, while the Antarctic is a continent surrounded by ocean. This leads to differences in ocean currents and heat transport. The currents around Antarctica isolate the continent from global weather patterns, helping to keep it colder.

Atmospheric Heat Transport: The Arctic is warmed by atmospheric heat transport from lower latitudes. This is less the case for Antarctica, which is somewhat isolated from the rest of the global climate system due to the circumpolar vortex - a persistent, large-scale cyclone centered near the Earth's pole, in the middle and upper troposphere and the stratosphere.

Presence of Ozone Hole: In Antarctica, the presence of the ozone hole has also led to cooling in the summer season. This is because the hole leads to the destruction of stratospheric ozone, which reduces the absorption of ultraviolet light. This has had a localized cooling effect, which has partially offset the warming from increased greenhouse gases.

All these factors contribute to the differences between Arctic and Antarctic responses to global warming. However, global warming is impacting both regions significantly, and scientists predict that Antarctica will also experience substantial warming in the long term.
