Despite the U.S. cold snap, January was hot hot hot

Subscribe to The Beacon

This January should be remembered for its unusual warmth, not its cold.

Yes, it’s so cold right now that even hardy Minneapolis is shutting down schools, but even with these few days of extreme cold, Minnesota should end up with a near “normal” month thanks to weeks of unusual warmth. It was in the 70s and 80s as far north as Maryland on New Year’s Day. Alaska has been so warm that they’re canceling sled dog races. So far this month, there have been 651 record daily highs across the United States, compared to 321 record daily lows — a roughly 2-to-1 ratio. And that’s just in the U.S.

Globally, the ratio of record highs to lows was about 20-to-1, with new all-time records in Namibia, Chile, and Reunion Island.

It’s summer in the southern hemisphere, and a brutal heat wave in Australia is melting roads and killing wildlife on a mass scale. On January 18, one town never dropped below 96.6 degrees F — marking the hottest night in Australian history. Thursday was the hottest day so far in relatively mild Sydney, with temperatures reaching 104 degrees F and knocking out power for tens of thousands of people.

Ongoing bushfires in Tasmania are threatening a World Heritage site with thousand-year-old pine trees — parts of the same area burned in 2016. Fires in this protected alpine wilderness were once unheard of; now they’re becoming routine.

To put it bluntly, events like this can’t happen in a normal climate. The harsh truth is we are not only losing the weather of the past, but there’s no hope of it stabilizing any time soon.

Underlying this warmth and extreme weather is the irreversible heat buildup of the oceans. The waters in the South Pacific are off the charts right now, triggering the highest alert for coral bleaching and boosting the likelihood of significant mortality in marine ecosystems. Sea ice on both poles is near record lows, with profound effects for the world’s weather. Current temperatures in the Arctic are likely the warmest they’ve been in at least 115,000 years, with melting ice beginning to reveal plants and landscapes buried for at least 40,000 years, according to new research.

Climate change is the sum effect of changes to daily weather, and our weather these days is bordering on indescribable. We are pushing the atmosphere into uncharted territory. That means what happens next is inherently unpredictable.

According to the Trump administration’s just-completed National Climate Assessment, “positive feedbacks (self-reinforcing cycles) within the climate system have the potential to accelerate human-induced climate change and even shift the Earth’s climate system, in part or in whole, into new states that are very different from those experienced in the recent past.”

The real danger of climate change is not that we are proving ourselves unable to heed scientists’ warnings, but that those warnings are inherently too cautious and we’ve already gone past the point of no return. Even the bombshell IPCC report, which recently kicked off an unprecedented youth movement advocating for a Green New Deal, may have underestimated how dire things truly are.

This is the core truth of our time: We have left the stable climate era that gave rise to civilization. Our society is brittle, and our new context — for generations to come — will be constant change. Even if we manage to rapidly stabilize greenhouse gas emissions in the next 10 years or so, as the IPCC report says we must, weather will continue to worsen for decades and the seas will continue to rise for hundreds of years.

With this extreme month as yet another warning sign, we need to wrap our heads around what it will take to match our solutions with the scale of the problem.

House Democrats just told the Pentagon to redo its climate change report

Subscribe to The Beacon

This story was originally published by Mother Jones and is reproduced here as part of the Climate Desk collaboration.

Earlier this month, the Pentagon released a landmark report that identified the 79 American military installations most vulnerable to the “effects of a changing climate.” The 22-page filing frankly acknowledged the security implications of climate change — in dramatic contrast with President Trump’s very public global warming skepticism — but Democrats roundly criticized its failure to include several details requested by Congress, including specific cost estimates to protect or replace the ten most vulnerable bases from each of the military services.

Now those lawmakers want a complete do-over.

In a letter released Wednesday afternoon, three Democratic members of the House Armed Services panel, including Chair Adam Smith from Washington state, urged Acting Defense Secretary Patrick Shanahan to compile another report by April that “thoroughly and clearly addresses” the criteria requested by Congress.

“They clearly ignored the requirement in the law,” says Representative Jim Langevin of Rhode Island, one of the signatories, who had described himself as “deeply disappointed” with the original report. “The report they issued was completely unsatisfactory.” Senator Jack Reed of Rhode Island, the ranking member on the Senate Armed Services panel, said the report carried “about as much value as a phonebook.” Smith immediately demanded another report that “rigorously confronts the realities of our warming planet.”

Heather Babb, a Defense Department spokesperson, attempted to explain the priorities, saying earlier this month that Pentagon officials “focused on mission assurance” when compiling the report. “By using this alternative approach, we are able to highlight where there are operational risks,” she said. When asked about the new request on Wednesday, Babb said, “As with all congressional correspondence, we will respond directly to [the] authors of the letter.”

What was omitted in the first report that the Pentagon had a year to compile was striking. No Marine Corps installations were mentioned, for example, despite the fact that just four months before the report was released, Hurricane Florence slammed into Camp Lejeune, the Marines’ biggest base on the East Coast, costing more than $3 billion in damages. Omissions from other branches of the military were just as concerning. Tyndall Air Force Base in Florida, where Hurricane Michael devastated 95 percent of the buildings in October, was not included among the Air Force’s most vulnerable bases.

In the summer of 2017, as part of the debate over last year’s annual defense spending bill, Langevin introduced an amendment requesting that the Pentagon assess how best to mitigate climate-related threats across the armed services, down to the level of an estimated cost and combatant command requirements. Earlier that year, the Washington Post had reported that defense officials removed nearly two-dozen references to climate change from a draft survey of installations vulnerable to the threat, creating an embarrassing news cycle for the Pentagon.

The amendment was added by voice vote in committee and reaffirmed with bipartisan support on the floor of the House. In July, more than 40 members of Congress, including several Republicans, even wrote to former defense secretary Jim Mattis to remind him of the requirements included in the report. Notably, lawmakers said they had been “disturbed” by the Post story, as if to warn Mattis against inciting a similar firestorm.“We expect that when this report is delivered to Congress later this year, it will contain candid assessments in line with the clear instructions passed by Congress and signed into law by the President,” the letter stated.

The report clearly fell short of its goal in the first version and now, with Democrats in control of the House, Langevin said the Armed Services committee is considering several options in case the Pentagon ignores this new request, from subpoenaing documents to hauling relevant DOD staffers before the panel for testimony. “I hope this doesn’t become a long, dragged-out battle,” he said. At least one major ex-Pentagon official has already voiced his support for a new report. John Conger, the former assistant secretary of defense for energy, installations, and environment, noted in a blog post earlier this month that “DoD should make the transition from anecdote to analysis and provide a fuller assessment, as Congress directed.”

For Shanahan, now in his fifth week leading the Pentagon as Mattis’s acting successor, the challenge from House Democrats poses an important early test of how compliant he will be with Congress. Mattis, who fell out of favor with Trump and ultimately resigned once the president announced that he would withdraw U.S. troops from Syria, had long been viewed as a climate change realist in a Cabinet of deniers and skeptics. Shanahan, whose background had been in weapons acquisition and management as a career executive at Boeing, arrived at the Pentagon as deputy secretary without a history of making his public policy views explicit.

But in the months since he entered government as the No. 2 to Mattis, climate change has risen on the military’s agenda. The recently released annual worldwide threat assessment from the intelligence community even listed global warming as a menace to “low-lying military bases.” The Democrats’ request for a new report can potentially put Shanahan at loggerheads with Congress, which confirmed him as deputy secretary with wide bipartisan support, and Trump, who has indicated that Shanahan could remain acting secretary indefinitely. (A spokesperson for Shanahan was not immediately available for comment.)

Since the early days of the Trump administration, the Pentagon has quietly but firmly adopted a more proactive approach toward climate change in some areas. After years of degradation to shipyards in Virginia, Hawaii, Maine, and other states, the Navy submitted a $21 billion infrastructure plan last year to clear a backlog of maintenance work. Military leaders have also grown more assertive in confronting the possibility of security threats from Russia and China in a warmer Arctic. In the past, reports from the Pentagon and the independent Government Accountability Office have even catalogued the threat to hundreds of installations in the United States and abroad. But the reluctance some officials have shown toward openly contradicting their commander in chief has compromised lawmakers’ confidence in DOD’s willingness to seriously confront the security implications of a warming planet.

130,000: The number of Puerto Ricans who never returned after Maria

Invest in nonprofit journalism today.Donate now and every gift will be matched through 12/31.

When Hurricane Maria smashed directly into Puerto Rico in September of last year, it took an enormous toll on the island. The near-peak-intensity Category 4 storm destroyed the island’s power grid, caused more than an estimated 100 billion dollars in damage, and resulted in the deaths of thousands of people.

Now we have the numbers to understand how much the storm and its widespread devastation sped up the pace of migration.

In the disarray that followed, there was a max exodus to the U.S. mainland. In Florida alone, 200,000 Puerto Ricans arrived within the first two months after the storm made landfall. Many Puerto Ricans eventually returned, but an estimated 130,000 people — almost 4 percent of the population — permanently left the island between July 2017 and July 2018, according to newly released United States Census Bureau data. That’s saying a lot: No state saw its population decrease more than 1 percent for that same period, and most saw increases.

“Puerto Rico has seen a steady decline in population over the last decade,” said Sandra Johnson, a statistician at the Census Bureau, in a press release. “Hurricane Maria in September of 2017 further impacted that loss, both before and during the recovery period.”

While the island’s population has been dwindling for several years, Maria made living in Puerto Rico much, much harder. According to Census data, Puerto Rico has lost an average of about 55,000 people a year over the last seven years. But last year’s exodus alone was double that number. And it’s no wonder people left: with the extended power outages, communication lapses, and infrastructure failures, a large chunk of the workforce was forced off the island. Others left simply in order to find some semblance of normalcy.

For now, about 3 million people remain in the Island of Enchantment, but unmitigated climate change will fuel even more humanitarian disasters — putting the island at risk of yet another mass exodus.

1,656 pages too long? Climate report coauthor Katharine Hayhoe has 3 takeaways.

Subscribe to The Beacon

The 1,656-page National Climate Assessment can feel overwhelming if not broken up into actionable-sized pieces — not unlike climate change itself. Thankfully, report coauthor Katharine Hayhoe offered up some key takeaways in a webinar with the nonprofit news organization Climate Central on Monday. Hayhoe, an atmospheric scientist and political science professor at Texas Tech University, focused her presentation on a core message: Climate change is impacting everyone now.

“The myth that the science isn’t real, or that it’s something up for debate, is not the most dangerous myth that the largest number of people have bought into,” Hayhoe said. “There’s a belief that is just as pernicious: that global warming does not matter to me.”

To change this mindset, Hayhoe recommended shifting the narrative away from polar bears in the melting Arctic to how climate change is shaping people’s lives today, from wildfires in California to severe flooding in New York.

The new report offers the most up-to-date assessment of how climate change is affecting the United States. As Hayhoe said, it tackles “the myth that climate change is happening to people far away.” Three of her takeaways:

1. “There are already climate refugees in the United States.”

Louisiana’s Isle de Jean Charles, home to members of the Biloxi-Chitimacha-Choctaw tribe, has been swallowed by rising tides. In 1955 the island was 22,000 acres; today it’s only 320. Last year, state officials announced that the tribal nation would be evacuated to higher grounds.

However, many other indigenous communities face significant barriers to receiving relocation funding, as the report details. Slow-onset disasters like coastal erosion and melting permafrost deeply effect communities over time, but they often don’t qualify for relocation funding. The report highlights the need for more community-driven relocation plans.

2. “Hurricanes are getting stronger, bigger, and slower, meaning they can sit over us for longer.”

If you’ve noticed hurricanes getting worse in recent years, it’s not your imagination. Climate change is bringing wetter and more intense hurricanes to the United States. For example, one recent study showed that climate change made Hurricane Florence 50 percent worse. The storm dumped enough water to fill the Chesapeake Bay.

3. “Climate change hits us in the Achilles’ heel.”

Peering into a climate-changed future is a bit like looking into a fun-house mirror where all of your worst features are accentuated. Texas, for example, is susceptible to a host of climate hazards, from heatwaves to hurricanes. It’s experienced more costly weather disasters than any other state. Climate change will only boost these extremes, bringing even more drought, flooding, and high temperatures.

You may have heard that everything’s bigger in Texas. That’s certainly true of climate change.

Simon Winchester, New York Times bestselling author of The Professor and the Madman, examines the legendary annihilation in 1883 of the volcano-island of Krakatoa, which was followed by an immense tsunami that killed nearly forty thousand people. The effects of the immense waves were felt as far away as France. Barometers in Bogotá and Washington, D.C., went haywire. Bodies were washed up in Zanzibar. The sound of the island's destruction was heard in Australia and India and on islands thousands of miles away. Most significant of all — in view of today's new political climate — the eruption helped to trigger in Java a wave of murderous anti-Western militancy among fundamentalist Muslims, one of the first outbreaks of Islamic-inspired killings anywhere. Krakatoa gives us an entirely new perspective on this fascinating and iconic event. This P.S. edition features an extra 16 pages of insights into the book, including author interviews, recommended reading, and more.

When disaster hits, solar power beats coal

This story was originally published by Mother Jones and is reproduced here as part of the Climate Desk collaboration.

Within two weeks after Hurricane Maria devastated Puerto Rico, Richard Birt, a Las Vegas fire captain, flew to San Juan on what would be the first of many missions to try to get the island’s 96 fire stations up and running — not by fixing the problematical grid but by using solar power.

With the encouragement of San Juan fire chief Alberto Cruz Albarrán, logistical help from San Juan firefighters, and donated equipment from the company Sunrun, within a day-and-a-half a team outfitted the flat roofs of the fire department in Barrio Obrero — one of the poorer neighborhoods in San Juan — with solar panels. The panels and connected battery meant the station could be taken off the downed grid to run the most critical equipment including its 24-hour watch office that fielded calls, and its radio, lights, and doors.

Dear reader, like what you see here?

Keep Grist’s green journalism humming along by supporting us with a donation today. All donations made between now and September 29 will be matched dollar-for-dollar.

  

“When we got there the generator was broken, so there was no lights, no watch office, no radio, no anything,” Birt tells me in between his shifts at the Las Vegas fire station. “The idea [was] getting the watch office up so when someone walked up and said they had an emergency, they could respond.” With solar, the fire station had a backup option when the hastily repaired grid went down again — as it would repeatedly over the last 12 months. When Birt returned a few months later, he found that the crew had never unplugged the solar equipment. “With the grid going down, the firefighters felt they needed this up and running 24-hours a day and not have any gaps,” Birt recalls. “They said, ‘this works and the grid doesn’t.’”

Through the nonprofits Empowered By Light and Givepower, 10 fire stations in Puerto Rico have set up similar microgrids, and Birt hopes to raise millions more to finish the job. Other emergency responders have installed solar power as well. Solar panels filled the parking lot of a children’s hospital in San Juan, after Tesla made a donation to replace the hospital’s diesel generators.

Ensuring power for first responders in the wake of a disaster is a matter of life or death. “People died because of the lack of power,” Sunrun’s director of public policy in Puerto Rico Javier Rúa-Jovet said — 2,975 people in total. But the experiences of the children’s hospital in San Juan and the Barrio Obrero fire department are exceptions, because very few people in Puerto Rico have the option and resources to go solar.

Renewables account for just 2 percent of Puerto Rico’s electricity supply, making it among the most fossil-fuel reliant of nations and territories in the Caribbean. Which is to say, Puerto Rico is far from recognizing the vision solar companies had for a robust and self-reliant solar market. The reasons for this are a complicated mix of the lack of political will, legal obstacles, and the absence of enough federal assistance.

Maria, and the more recent storms like Hurricane Florence, tell a story about reliable power that’s quite different from what President Trump has claimed — which boils down to his usual support of fossil fuels. In a bid to subsidize the coal and nuclear plants that have struggled to compete economically against cheap gas and renewables, the Trump administration has floated a variety of plans — including stalling the retirements of coal plants for national security reasons and creating a strategic reserve for coal — that would allow it to subsidize these sources. One of the administration’s favorite arguments confuses the largely accurate observation that solar and wind are intermittent sources for energy (as in, the sun doesn’t always shine) with the more dubious logic that renewables are somehow more susceptible to security threats than a physical stockpile of coal.

It’s “a tremendous form of energy in the sense that in a military way — think of it — coal is indestructible,” Trump said at an August fundraiser on Long Island. “You can blow up a pipeline, you can blow up the windmills. You know, the windmills, boom, boom, boom, bing, that’s the end of that one.”

But that’s not what we’ve been seeing after catastrophic hurricanes. After Maria, solar power became a symbol for more reliable power, even if few had access to it. And more recently, Hurricane Florence tested the most solar-powered state after California. In North Carolina 4.6 percent of the state’s electricity comes from the sun. InsideClimate News reports that large solar farms and even rooftop solar (which face more variable conditions and are more susceptible to damage) remained intact following the storm. At the same time, those who live in North Carolina still saw massive power outages — at one point more than 300,000 residents were without power.

The upside of solar is that it easily lends itself to decentralized power and micro-grids that could maintain the power for more people in the wake of a disaster. Solar is “an easy distributed resource and obviously a clean one,” Vermont Law School’s Institute for Energy and the Environment Director Kevin Jones says. But the downside is that on its own it doesn’t lead to a more resilient a power grid, unless it is combined with advanced battery technology that allows people to disconnect from the grid to become self-reliant. Consider those fire stations: For a microgrid, panels on the roof had to be hooked up to long-lasting storage options. The combination of battery storage and solar could mean that “you have additional resilience when the grid goes down,” Jones notes.

An investigation by Puerto Rico’s Center for Investigative Journalism conducted after Hurricane Maria backs that up: “Most of the more than 10,362 renewable energy units installed by Puerto Ricans ended up as a roof ornaments,” they concluded. These units were connected to the grid; if they were microgrids with storage attached, things might have been different.

There are other barriers for more hurricane-resilient power. One is money. “You can have solar panels in a parking lot serving a children’s hospital in the short term, but in the longer term you have to put them in a place where you can have them permanently,” Jones says. “Those things take time and money and effort.” The second is public policy priorities. Supplying power to community members in a microgrid gets complicated, legally, because solar customers and companies must get permission from monopoly utilities. The uncertain future for Puerto Rico’s monopoly utility PREPA means an uncertain future for microgrids as well.

For now, multiple solar and storage companies are eyeing markets in Puerto Rico, and both companies and some residents have some hope for the future. Sunrun’s Javier Rúa-Jovet fits into both categories. He considers himself one of the lucky few who was able to take out a loan to buy a diesel generator after the storm, but remembers the frustration of dealing with maintaining and keeping the generator stocked with fuel, sometimes in the middle of a rainy night. “The costs aren’t only economical, there’s the psychological toll,” he said. But a switch to maintenance solar promises to be “a positive experience, not a stressful experience.”

Think the climate change lawsuit is dead? It’s just beginning.

Another climate change accountability lawsuit appears to have died. RIP. But take heart, you fine-feathered climate hawks. No man is an island, but every court is.

As you may recall, in January, New York City sued ExxonMobil, Chevron, BP, Shell, and ConocoPhillips, alleging that the companies had purposefully misled the public about the effects of climate change in order to keep raking in money.

United States District Judge John F. Keenan tossed the lawsuit straight in the proverbial trash can on Thursday. “Global warming and solutions thereto must be addressed by the two other branches of government,” Judge Keenan said.

Fat chance of that happening anytime soon.

Just last month, a U.S. district judge dismissed similar complaints against major oil companies brought by Oakland and San Francisco. “Using lawsuits to vilify the men and women who provide the energy we all need is neither honest nor constructive,” said R. Hewitt Pate, Chevron’s vice president and general counsel.

Both the California and New York suits were part of a wave of climate accountability lawsuits taking place across the country, from Rhode Island to Colorado to King County, Washington.

So are all these climate suits going to evaporate? Not quite.

“It’s easy to see this decision as momentum,” said Michael Burger, executive director of Columbia University’s Sabin Center for Climate Change Law. But “no other court is bound by this decision. It’s as simple as that.”

Just because one judge rules a certain way doesn’t mean other judges looking at similar cases will make the same decision. “Each judge and each panel of appellate judges is going to look at these issues independently until it gets resolved by some higher court,” Burger said.

What’s more, the New York lawsuit is likely to get appealed. That means it could get pulled out of that same proverbial trash can, dusted off, and sent along to the federal court of appeals. So Big Oil isn’t out of the woods quite yet. If a higher court does ultimately side with polluters, however, lower courts would likely follow that precedent.

Burger doesn’t know, ultimately, whether the dismissal of the New York case will change the outcome of the other climate suits. But he isn’t the only law expert who thinks this isn’t necessarily the end of the line.

“We remain optimistic that the majority of these cases will end up in state court where they belong, and that taxpayers will ultimately prevail in their efforts to recover costs,” Richard Wiles, executive director of the Center for Climate Integrity said in a statement.

5 Things Besides Sunscreen That Are Bad for Coral Reefs

Coral Reef Awareness Week, in the third week of July each year, was created to highlight the importance of coral reefs and the need to protect them. Coral reefs only cover 0.2 percent of the ocean floor, but these amazing ecosystems support around 2 million species of marine plants and animals. In addition, more than 500 million people throughout the world rely on coral reefs for food and income.

Coral reefs have been on the earth for about 500 million years. But in the past few decades, coral reefs have been dying at an alarming rate. It?s estimated that 19 percent of the world?s coral reefs are already dead, and 60 percent are currently at risk. If global action is not taken to stop this decline, all coral reefs will be in danger by 2050.

You may have heard about how sunscreen can be toxic to coral reefs, but many other factors also impact the health of coral reefs. Let?s look at some of the worst threats coral reefs currently face.

1. Climate Change

Research suggests that climate change is quickly becoming the most significant threat to coral reefs today.

A coral reef is actually a community of hundreds to thousands of corals, which are small, delicate animals that are easily disrupted by changes in their environment. Each tiny, soft-bodied coral secretes a hard outer skeleton of limestone to keep itself safe. The accumulation of these skeletons creates a coral reef.

This process has been going on uninterrupted for thousands of years and has created the massive coral structures we know today. But corals also form an incredible partnership with a type of algae known as zooxanthellae to keep this cycle going. Zooxanthellae are single-celled algae that can live within the corals? soft tissues, where they photosynthesize in a way similar to plants. The corals can then feed off the products of the algae?s photosynthesis and continue to grow and thrive.

It?s been observed that a rise in ocean temperatures of only one or two degrees can disrupt this unique partnership. When oceanwater heats up, the zooxanthellae start producing toxins, which forces the corals to eject the algae back into the ocean. Without the zooxanthellae, corals lose a vital food source and slowly die. This process is known as coral ?bleaching? because the colorful, living algae and corals are gone, leaving only the white limestone skeletons behind.

Climate change is causing a rise in overall ocean temperatures, as well as increasing the likelihood of localized temperature spikes. A chilling example of this was a ten-month long stretch of abnormally warm water around Christmas Island in the Indian Ocean from July 2015 to April 2016. In the months following the temperature spike, 90 percent of the reef?s corals died.

Another deadly trend fueled by climate change is ocean acidification. Every day, 90 million tons of carbon pollution is released into our atmosphere. About one-third of that carbon is absorbed by our oceans, which is gradually altering the chemistry of seawater and making it more acidic. The chemical changes make it more difficult for corals to acquire the nutrients they need to survive, causing a slower decline than bleaching, but with a similarly fatal end.

2. Over-Fishing

Global demand for fish continues to increase, both for food and for the pet trade. Over-harvesting of fish to meet this demand is taking a toll on biodiversity and the ecological balance of coral reefs. Physically damaging fishing methods, such as trawling or using dynamite or cyanide in the water, can also damage or completely destroy coral reefs.

3. Pollution

Pollution affects our entire planet, including our oceans. A 2013 study found that fine airborne particles, produced largely by human industrial activities, actually block sunlight from reaching corals, which impacts photosynthesis and growth. Researchers examined coral reefs in Panama and Belize and found their growth rates have been slowing down since the 1950s because of this reduction in sunlight.

In addition, the 8 million tons of plastic that enter the world?s oceans each year disrupt countless numbers of marine plants and animals, including corals, who will eat tiny plastic pieces thinking they?re food. Many other sources of pollution, such as oil spills, sewage and agricultural runoff, also take a toll on coral reefs.

4. Human Activities

Irresponsible human recreation, such as careless swimming, snorkeling or diving, can damage coral reefs. Boating can also hurt coral reefs through noise pollution, dropping anchors on sensitive areas or collisions with wildlife.

Human coastal development is another threat. Sensitive marine areas are being dredged and disturbed to construct airports and buildings on land reclaimed from the sea. Also, building marinas, fish farms and other water-based structures can disrupt nearby coral reefs.

5. Disease

The frequency of coral disease appears to be on the rise, primarily by infection from bacteria, fungi or viruses. Scientists believe this is largely due to the increased environmental and physical impacts corals are currently facing, which weakens their natural defenses.

For example, an Australian study looked at the effect of permanent offshore visitor platforms that had been constructed within the Great Barrier Reef Marine Park. Researchers found that coral disease was up to 18 times more likely in reefs with platforms compared to undisturbed reefs.

WHAT YOU CAN DO TO HELP CORAL REEFS

The World Resources Institute has a great video summarizing their Reefs at Risk report, which examined the state of the world?s coral reefs and what we can do to bring them back to health. Check it out below.

If you’re just now hearing about the fellowship, here’s the deal: We’re looking for early-career journalists to come work with us for six-month stints. This time around, we’re looking for all-stars in three areas: news, environmental justice, and video. You’ll find a full program description and application requirements here.

Our past fellows are continuing to do high-impact work. Emma Foehringer Merchant has you covered on all things energy and policy at Greentech Media. Sabrina Imbler makes consumers smarter about upcycled bananas and lots more at The Wirecutter, a New York Times Company. Vishakha Darbha, a digital fellow at Mother Jones, produces videos on forced family separations and other of-the-moment topics. Raven Rakia recently received a Livingston Award finalist nod for her powerful piece on The Intercept about women visitors at Rikers Island jail complaining of invasive searches. And break out the bubbly: Recent environmental justice fellow Justine Calma just joined Grist as a staff writer.

So what are you waiting for? Oh, right, the last possible minute. As long as we receive your application by 11:59 p.m. PT on July 9, no judgment here.
