How have Arthur Evans's reconstruction efforts at Knossos impacted modern archaeological research and interpretation of the site?

Evans's imaginative reconstructions, while creating a visually impressive site for visitors, complicate modern research. The extensive alterations make it difficult to determine the original purpose and layout of the Minoan palace at Knossos, potentially preventing complete understanding of Minoan infrastructure and daily life. The blend of fact and artistic license leaves a lasting impact on interpretations of the Minoan civilization.

What specific mechanisms link climate change to the increased occurrence and severity of temperature flips, both on a large and small scale?

The study published in Nature Communications reveals a direct link between rising greenhouse gas emissions and more frequent, severe temperature "flips." These flips, transitions from extreme heat to cold or vice versa, are not new but are exacerbated by climate change, impacting both large-scale atmospheric patterns (jet stream) and local conditions (humidity, cloud cover).
