@JonShmo Super cool! Thanks for sharing.

🍃These maps compare this year's leaf-out dates to the first bloom dates. Several areas were in sync. What was extremely rare was the combination of early leaves but late blooms. 💮
If you find an example let us know in the comments!

ENSO-neutral conditions are expected to continue through summer.

While the odds of La Niña increase through the fall, the odds of neutral conditions continuing slightly outweigh those of La Niña.

Find out what ENSO-neutral means for seasonal prediction? https://t.co/MLfjvva5vQ

JUST IN: Atmospheric carbon dioxide (CO2) concentrations have peaked for the year at 430.5 ppm.📈
This is 3.6 ppm higher than last year and the second largest May-May increase in the 67-year Mauna Loa record. In 2023, the CO2 peaked at 424 ppm.

Atmospheric signs of this past winter’s La Niña continue to weaken. As the tropics settle into ENSO-neutral territory, other patterns have a chance of influencing seasonal climate. Will La Niña re-emerge? Our blogger breaks down the odds. Read more: https://t.co/twTjpQSAmZ
