Scientists detect Earth's deadliest extinction signs in today's oceans: Great Dying started with warming seas and oxygen loss; 70% of land animals vanished

The research explains why some marine animals survived while others nearly disappeared, offering fresh insight into how modern climate change could affect ocean ecosystems.
