Ocean Acidification w/ Earth Sciences NZ (Programme Leader for Oceanic Control of Atmospheric Composition), Dr Cliff Law: 14 October, 2025

Since the Industrial Revolution in 1840, the burning of fossil fuels and land use change have increased the concentration of atmospheric carbon dioxide.

While much of this excess carbon dioxide remains in the atmosphere, a significant portion is absorbed by the oceans. As a result, the pH of the oceans is steadily decreasing, threatening marine ecosystems, biodiversity, and the communities that depend on them.

This week, Leilani spoke to Dr Cliff Law from Earth Sciences New Zealand about ocean acidification
