Scientists from the Australian Institute of Marine Science report that the Great Barrier Reef, the world’s largest reef system (visible from space), is facing historic peril. Not that this is news. Mother Jones has reported extensively on the subject. But new research published in the journal Science includes the largest study to date about environmental damage to Australia’s reefs.

The reef is experiencing is slowest growth rate in nearly 400 years, and gone unchecked, could lead to zero growth by 2050, says Glenn De’ath, the study’s co-author. “When you disturb an ecosystem in this way, you get a cascading effect. You then get a chain reaction — the fish habitat is lost.”

What’s to blame? The usual suspect: global warming. Rising sea temperatures are causing coral bleaching, in which corals release the algae which nourish them. The effect is grimly obvious underwater, where previously vibrantly colored reefs come appear like piles of bones. Without algae, corals eventually die. Says De’ath, “We may have seriously underestimated the rate of climate change and this should compel us to drastic steps to decarbonise Australian and global economic systems.”

Fact:

In-depth journalism that investigates the powerful takes real money and is so damn important right now.But it doesn’t take a Mother Jones investigation to know that billionaires and corporations will never fund the type of reporting (like they do politicians) we do that exists to help bring about change. Instead, our mission-driven journalism is made possible by people power, and has been for 46 years now since our founding as a non-profit.

In “TITLE TK” Monica Bauerlein writes about the perilous moment we’re in, and why it’s so important that we raise $325,000 by the time November’s midterms are decided so we can be ready to throw everything we have at the big issues facing the nation no matter what happens.
