El Niño development continues: the latest daily Niño 3.4 Index is +0.11˚C & has been positive for the past week 📈

As a point of comparison, at this time in 1997 (1982) it was -0.09˚C (-0.05˚C).

No two events are the same, but 2023's warmth is more substantial than those years. pic.twitter.com/bGweiz72gv
