Det giver ikke rigtigt noget med et par kurver uden angivelse af kilde. Her er faktuel viden om Antarktis fra ChatGBT, der trods ekstreme vejrforhold også opvarmes: The Antarctic continent as a whole has experienced significant warming of approximately (0.12\degree C) per decade from 1980 to 2023. However, this trend varies regionally, with West Antarctica and the Antarctic Peninsula showing the most pronounced and statistically significant warming, while the warming is less pronounced elsewhere. Some models also show a trend of warming in the interior of the continent, while other processes like dynamics have a cooling effect that partially offsets the warming. Overall trends Continent-wide warming: Studies using reanalysis datasets show a statistically significant warming rate of about \(0.12\degree C) per decade for the entire Antarctic continent from 1980 to 2023.Regional variations: The warming is not uniform. West Antarctica and Antarctic Peninsula: These regions are warming the fastest and show the most statistically robust warming trends. East Antarctica: Some parts of East Antarctica have experienced significant positive temperature anomalies, especially during winter. Key factors Thermodynamic processes: These have a strong warming effect on the continent, contributing to an increase of about (0.22\degree C) per decade. Dynamic processes: These have a cooling effect, which partially offsets the warming from thermodynamic processes, with a rate of around (-0.10\degree C) per decade. Other observations Recent shifts: There has been a notable shift in temperature trends in the early 2000s. Seasonal differences: Some analyses have found that winter warming rates have been larger than summer warming rates in certain regions. Data limitations: The lack of extensive long-term in-situ observations makes it challenging to fully understand Antarctic climate change, but reanalysis datasets help fill this gap.

En opvarmning på cirka (0,12°C) pr. årti er ingenting. Det er komplet ligegyldigt. For Antarktis som helhed er den årlige gennemsnitlige temperatur på omkring –45 °C |
