We knew coral bleaching was a serious issue in the Great Barrier Reef, but the scope of just how widespread it was has been unclear — until now.

Extensive aerial surveys and dives have revealed that 93 percent of the world’s largest reef has been devastated by coral bleaching. The culprit has been record-warm water driven by El Niño and climate change that has cooked the life out of corals.

The unprecedented destruction brought leading reef scientist Terry Hughes, who runs the ARC Center of Excellence for Coral Reef Studies, to tears.

“We’ve never seen anything like this scale of bleaching before. In the northern Great Barrier Reef, it’s like 10 cyclones have come ashore all at once,” Hughes said in a press release.

The Center conducted aerial surveys and dives at 911 sites spanning the full 1,430-mile length of the reef. They show the hardest hit areas are in the northern part of the reefs, which have also endured some of the hottest water temperatures for prolonged periods.

More than 80 percent of reefs surveyed there showed signs of severe bleaching. The southern end of the reef fared better, but overall the bleaching represents a massive blow to biodiversity at the UNESCO World Heritage Site.

The Great Barrier Reef also faces pressure from ocean acidification and fishing impacts, ramping up concerns over how to protect one of the most unique ecosystems on the planet.

Beyond its beauty, the Great Barrier Reef also has a huge economic benefit on the Australian economy. It generates $4.45 billion in tourism revenue annually and supports nearly 70,000 jobs, according to the Great Barrier Reef Marine Park Authority.

The damage caused by this round of bleaching will be felt for decades, but it’s not the only reef around the globe to feel the heat of climate change. 2015 marked the third global coral bleaching event ever recorded. This one been the longest of the three as hot ocean temperatures fueled by El Niño and climate change have caused reefs to suffer across every ocean basin.

While every basin has been hit, some reefs and coral species have survived through the event. That has scientists trying to quickly understand why the survivors made it through. That knowledge could be crucial to ensure reefs continue to survive as oceans temperatures continue their inexorable rise and water becomes more acidic due to climate change.

“We can’t afford to sit by and watch climate change drive all the world’s coral reefs to extinctions by the end of the century,” Julia Baum, a reef researcher at the University of Victoria, said.

On the Selma Anniversary, These North Carolina Activists Will March Backwards

Mother Jones

Activists, politicians, and luminaries from across the nation will flock to Selma, Alabama, this weekend to commemorate the 50th anniversary of the nonviolent voting-rights march that was undermined by police-sanctioned attacks, presaging the passage, six months later, of the Voting Rights Act of 1965. But this year’s events, which include a reenactment of the fateful march across the Edmund Pettus Bridge, are shaping up to have a more activist edge than past commemorations.

Some black leaders, such as North Carolina NAACP president Rev. Doctor William Barber II, will use the day to highlight the assault on black voting rights in the wake of a 2013 Supreme Court decision that rolled back a key provision of the Voting Rights Act. Rather than make it across the bridge, Barber and his delegation plan to turn around and march back toward Selma.

“For the last fifty years we’ve been walking across that bridge to celebrate how the civil rights leaders pushed us forward. This year, we have to turn around,” he told me. This change in routine, he says, is a response to the politicians who “will come down to Selma and give all these platitudes and talk about how they love the people of the past, but won’t ensure a Voting Rights Act that meets the test of history today.” And that “is a step backward.”

Prior to the Supreme Court ruling, the VRA required nine historically racist states, including North Carolina, along with several counties, to get permission from the Department of Justice before modifying their voting laws. It paid off. In 2012, for instance, North Carolina ranked 11th out of 50 states in voter turnout, with 65 percent of registered voters casting a ballot.

But the gains, ironically enough, helped influence the court’s decision in the case of Shelby County v. Holder. Writing for the majority, Chief Justice John Roberts Jr. held that it was unconstitutional to single out just a few states for these voting requirements, especially after all this time—”nearly 50 years later,” he wrote, “things have changed dramatically.”

They can change back, too. In her dissent, Justice Ruth Bader Ginsburg likened the majority’s reasoning to throwing away an umbrella in a rainstorm because you are not getting wet.

Prescient words: Freed from DOJ oversight, several of those states quickly reversed course, enacting a deluge of new, restrictive voting laws. Within two months of the ruling, North Carolina Gov. Pat McCrory signed a package of legislation that was, for anyone who favors access to the ballot box, a nightmare: Same day registration? Gone. Pre-registration for for 16- and 17-year-olds? Also gone. A shorter early registration period? Check. Extended voting hours when voting demand exceeds the availability of voting machines? Nixed. The ability to vote in a precinct outside of where one resides? Nope. Then there’s the most contested provision: the requirement for voters to present a state-approved ID starting in 2016. Without a valid driver’s license, state ID card, US military ID, veteran card, or passport, North Carolina voters are out of luck.

“Voting should not difficult. It should not be something that we have to jump over hurdles to do,” says Donita Judge, a senior attorney at the Advancement Project, a civil rights nonprofit. She and her colleagues promptly sued the state over the new voting restrictions. A number of other groups, including the League of Women Voters, has joined the lawsuit, which is set for a trial in July.

A similar lawsuit filed by the DOJ not long after prompted sneers from Gov. McCrory: “I believe if showing a voter ID is good enough and fair enough for our own president in Illinois, then it’s good enough for the people in North Carolina.” The package, he said, is “common sense reform” aimed at curbing voter fraud and maintaining democratic integrity. Never mind that, between 2000 and 2010, there were 47,000 reported UFO sightings, but only 13 credible cases of someone trying to impersonate a voter. “It’s a red herring. It’s been proven time and time again that there is very minimal voting fraud,” Judge says. “What we do have is politicians manipulating elections—it’s more election fraud then voting fraud.”

Indeed, the sorts of restrictions North Carolina has put in place have been shown time and again to have a disproportionate impact on minority voters. The Advancement Project notes that black turnout leaped from 42 percent in 2000 to 69 percent in 2012 after same-day registration and early voting were implemented. (Granted, there wasn’t an electable black guy running in 2000.) But in 2013, Democracy North Carolina released a report showing that 34 percent of the state’s registered black voters lacked a state-issued ID—overall, 318,000 registered voters lack one, according to data from the state board of elections.

“When people can’t vote, they lack the ability to choose who represents them and therefore who has their best interest at heart, but they also lack the ability to weigh in on important issues, like the criminal justice system,” Judge says. “If you can’t vote, you’re not going to end up on juries, so you don’t have a voice.”

Hence the backward march. “Fifty years ago, they didn’t settle in the face of death, in the face of the Klan, in the face of accepted police brutality. And if they didn’t accept then, we can’t accept now,” Rev. Barber explains. “If they died for us to have these rights, there is no way in the world we can be afraid of the Koch Brothers, of the Tea Party, of regressive politicians.”
