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.”

IT'S NOT THAT WE'RE SCREWED WITHOUT TRUMP:

"It's that we're screwed with or without him if we can't show the public that what we do matters for the long term," writes Mother Jones CEO Monika Bauerlein as she kicks off our drive to raise $350,000 in donations from readers by July 17.

This is a big one for us. It's our first time asking for an outpouring of support since screams of FAKE NEWS and so much of what Trump stood for made everything we do so visceral. Like most newsrooms, we face incredibly hard budget realities, and it's unnerving needing to raise big money when traffic is down.

So, as we ask you to consider supporting our team's journalism, we thought we'd slow down and check in about where Mother Jones is and where we're going after the chaotic last several years. This comparatively slow moment is also an urgent one for Mother Jones: You can read more in "Slow News Is Good News," and if you're able to, please support our team's hard-hitting journalism and help us reach our big $350,000 goal with a donation today.
