3 million years ago, greenhouse gas was lower (at 360ppm). Temperatures were warmer, and sea levels were 20 meters higher.
Professor Gavin Foster: “The reason we don’t see #Pliocene-like temperatures and sea-levels yet today is because it takes a while for Earth’s @climate to fully equilibrate (catch up) to higher CO2 levels and, because of human emissions, CO2 levels are still climbing.”

Centrolene kutuku: A New #Glassfrog of the Genus Centrolene from the Subandean Kutukú Cordillera, eastern Ecuador https://novataxa.blogspot.com/2024/07/centrolene.html #Frogs #Frog #Animals
"The #NewSpecies is sister to Centrolene camposi from the #WesternCordillera of the #Andes of southwestern #Ecuador, and together they form a clade with C. condor from the Subandean Cóndor #Cordillera in southeastern Ecuador... the new species originated at the end of the #Pliocene."
