ocean acidification

Two Tales of Acidification–The Old and the New

If you thought the worst extinction event on Earth was the one that killed the dinosaurs some 66 million years ago, think again. A far worse event, the Permo-Triassic Boundary mass extinction event, happened some 252 million years ago, which over the course of about 60,000 years is thought to have wiped out more than two-thirds of land species and more than 90% of marine species on the planet.

“…oceans are taking a beating”

“… the latest pH level readings from the world’s oceans indicate that these ancient pH levels have recently dropped to an average of 8.1. As the ocean becomes more acidic, the life cycles of marine organisms, especially zooplankton primarily found in surface waters and at the lower end of the food chain, could be affected.”
