Temperature spikes lead to change in El Nino labelling, PgII

Key Highlights:

• Meteorologists report the El Nino cycle is influenced by and contributes to global warming.
• A recent study explains the earth's temperature spike using changes in the El Nino/La Nina cycle.
• The NOAA has updated its El Nino/La Nina labeling due to rapid weather changes from global warming.
• Earth's average monthly temperature noticeably increased starting in early 2023, continuing through 2025.

Detailed Insights:

• The shift from a three-year La Nina to El Nino explains about three-quarters of the change in earth's energy imbalance.
• From 2020 to 2023, Earth experienced an unusual "triple dip" La Nina, which trapped warm water at deeper depths.
• The increased energy imbalance, resulting in warmer temperatures, is attributed to long-term climate change and the shift in El Nino/La Nina patterns.
• About 23% of the energy imbalance driving higher temperatures comes from the long La Nina pattern, while over half is from greenhouse gases.

Scientific/Technical Concepts Involved:

• El Nino: Cyclical warming of the equatorial Pacific that alters global weather patterns.
• La Nina: Marked by cooler-than-average waters in the equatorial Pacific.
• Earth's Energy Imbalance: The difference between energy coming to and leaving the planet.
