Critical moment when El Niño started to erode Russia's Arctic sea ice discovered
- New study links faster ENSO phase transitions since 2000 to greater Arctic sea ice loss northeast of Russia.
- Researchers analyzed data from 1979–2023 to link ENSO shifts with fall sea ice changes in the Laptev and East Siberian seas.
- Cold patches formed after ENSO shifts push a high-pressure system north, pulling heat into the Arctic and melting ice.
- The WNPAC northward movement helps form an anticyclone over Arctic seas, accelerating ice melt.
- Study may improve sea ice predictions for ships navigating the Arctic region.
- Researchers note natural cycles drive the pattern, but human-caused warming adds uncertainty.
- The study analyzed ENSO impacts using data from 1979 to 2023 across Arctic seas northeast of Russia.
- Co-authors emphasize the link between ENSO transitions and Arctic ice loss could aid maritime safety.
- The article discusses El Niño–Southern Oscillation as a climate driver affecting global weather.
- Experts highlight ongoing research into how human warming interacts with natural climate cycles.
