Academics think brackish water harming dolphins

Dolphins (like whales) ancestors originally evolved from land animals around the Eocene around 50million years ago the Eocene was considerable warmer than present times see 65 Myr Climate Change chart. Both charts are from Wiki.

Dolphins in the modern form are known in the fossil record from over 12 million years ago and have survived periods warmer than now plus multiple ice ages with attendant sudden climate shifts we could not imagine.

The ABC has this article – Burrunan dolphin deaths linked to Fresh Water Skin Disease caused by climate change – I marvel at the “scientific” conclusions behind this article. One thing certain is that a population as small as numbers quoted is at risk of dying out regardless of changes in rainfall.
