In the past 50 years where has the temperature changed the most?

In the past 50 years, the Arctic region has experienced the most significant temperature changes, with some areas warming at nearly twice the global average. This rapid warming is largely attributed to climate change, resulting in melting ice, thawing permafrost, and alterations in ecosystems. Additionally, regions such as Alaska and parts of Siberia have also shown marked increases in temperature, contributing to broader environmental impacts.
