Researchers examined speleothems in southeastern Alaska, revealing that El Niño's drivers have shifted since the 1970s, with human-made climate change playing a more prominent role. In another study, a new concept, the "Walker switch," challenged the traditional "bipolar seesaw mechanism" by showing that changes in solar radiation can swiftly affect sea-surface temperatures in the equatorial Pacific, influencing high northern latitude climates, including Alaska and the North Atlantic. These findings emphasise the intricate nature of Earth's climate system, with the need for ongoing research to understand climate processes.
