 Australian scientists have  released a new report on climate change in the Pacific detailing rising sea levels, increasing temperatures andincreases in ocean acidity with  drastic implications for coral-based eco-systems from hitting home in less than 40 years. “The Pacific is getting hotter, sea-levels are rising, rainfall is changing, and equatorial winds have weakened,” said researcher, […]

Rising CO2 means faster ocean acidification

Peter Griffin posted in on October 28th, 2008.

Australian marine scientists claim rising carbon dioxide levels in the world’s ocean could deal a “disastrous blow” to coral reefs, which are already subject to bleaching and destruction of their ecosystem. New research from the ARC Centre of Excellence for Coral Reef Studies and the University of Queensland, to be published in PNAS this week, […]
