Example Input: Paragraph: A day after Australia recorded its hottest day on record, thick smoke blanketed the harbor city, shrouded the Opera House and brought many outdoor activities to a halt. The state of emergency declaration gave firefighters broad powers to control government resources, force evacuations, close roads and shut down utilities across New South Wales, which is home to more than 7 million people. Authorities said nearly 120 fires remained ablaze by late afternoon, more than half of which are uncontrolled, and with temperatures forecast to top 45 degrees Celsius (113°F) in some areas, officials warned residents to be on high alert. “The firefront has been spreading very quickly and intensely,” NSW Rural Fire Service (RFS) Commissioner Shane Fitzsimmons told reporters in Sydney, adding that two firefighters had been airlifted to hospital with burns to their faces and airways. “It’s still a very difficult and dangerous set of circumstances.”  Days out from Christmas, a time when many Australians head to the coast for the holidays, NSW Premier Gladys Berejiklian advised people to make sure “you are prepared to change your plans should circumstances change.”  In Shoalhaven, a popular coastal destination some 190 km (120 miles) south of Sydney, local mayor Amanda Findley said people were poised to evacuate. “There is a large amount of smoke looming over the city, which shows how close the fire is,” Findley told Reuters by telephone. “It is extremely hot and windy now so we are all worried the fire could spread. People are really worried that they may lose everything.”  The RFS posted footage on its official Twitter account showing firefighters tackling one of the three blazes ringing Sydney. A waterbomber aircraft was dwarfed by thick grey and black billowing cloud as it attempted to douse flames in bushland just meters away from homes. Australia has been battling wildfires across much of its east coast for weeks, leaving six people dead, more than 680 homes destroyed and nearly 3 million acres (1.2 million hectares) of bushland burnt. Berejiklian said as many as 40 homes had been destroyed on Thursday. Australia on Wednesday broke all-time heat records for the second day running, with maximum temperatures reaching an average of 41.9 degree Celsius, the Bureau of Meteorology said. Some 1,700 firefighters have been deployed across NSW, but officials warned that was still not enough to cover every potential danger and urged people in high risk areas to evacuate while it was still safe to do so. The current state of emergency will last for seven days, while a total fire ban that has been in place since Tuesday will remain until midnight on Saturday. The major fires around Sydney, which is home to more than 5 million people, have resulted in days of heavy pollution in the city usually known for its sparkling harbor and blue skies. One megafire in the Kanangra Boyd National Park to the city’s southwest had crept to the very outskirts of Campbelltown, a suburb of 157,000 people. By late afternoon, Sydney was sitting at No.4 on the IQAir AirVisual live rankings of pollution in global cities, above Dhaka, Mumbai, Shanghai and Jakarta. Many commuters have donned breathing masks in recent weeks as air quality has plunged to hazardous levels not previously seen in the city. NSW Ambulance Commissioner Dominic Morgan said the service had experienced a 10% surge in call-outs for patients suffering respiratory conditions over the past week and urged susceptible people to remain indoors and keep their medication close. Prime Minister Scott Morrison has weathered a storm of criticism on social media in recent days for going on an overseas holiday during the emergency, adding to criticism that his government is failing to deliver adequate climate change policies. As local media reported Morrison was in Hawaii on a family holiday, about 500 protesters gathered outside his official Sydney residence to demand urgent action on climate change. Morrison’s office refused to confirm his whereabouts. One protestor, wearing an Hawaiian shirt, carried a sign reading, “ScoMo, where the bloody hell are you?” referencing the leader’s nickname and a decade-old international advertisement for Tourism Australia that was banned in several countries because the language was deemed offensive. Australia’s low-lying Pacific neighbors have been particularly critical of the coal-rich nation’s climate policies following modest progress at the U.N. climate talks in Madrid. “It was particularly disappointing to see our Pacific cousins in Australia actively standing in the way of progress at a time when we have been watching in horror as their own country is ablaze,” Marshall Islands president Hilda Heine said in a statement on Wednesday. Claim: Ring of fire: Australian state declares emergency as wildfires approach Sydney.
Example Output: Australia’s most populous state declared its second emergency in as many months on Thursday as extreme heat and strong winds stoked more than 100 bushfires, including three major blazes on Sydney’s doorstep.

Example Input: Paragraph: Central to the plan to protect the city, some or all of the 78 barriers will one day be raised when the sea rises more than 110 centimeters (43 inches), to prevent damaging high tides from pushing into the lagoon city, a world heritage site built picturesquely — but somewhat precariously — upon more than 120 islands. Concerns that high tides are becoming more frequent because of climate change have increased the urgency. While the concept is simple, its realization has been anything but. The system of movable underwater barriers, dubbed Moses, has been beset by corruption, cost overruns and delays. Projected at 1.8 billion euros ($2 billion) and meant to be completed by 2011, the project has so far cost 5.5 billion euros and is running a decade behind schedule. In the wake of last month’s flooding of Venice, the worst in 53 years, the consortium that oversees construction of Moses is eager to demonstrate that the project — after years of bad news — is on track and will be fully operational by the end of 2021. Venetians say they cannot afford to be wrong. Skeptics and critics say they may be. A recent test of the deepest expanse of barriers — at the Malamocco entrance to the lagoon — was declared a success by the New Venice Consortium. It was the last of the four sections of barriers to be completely raised — but so far only in calm seas. The real test will come when all four are raised at once, and not only in serene waters, but under flood conditions. That isn’t scheduled to take place until the end of next year. It took six years to test each of the four movable sea walls covering the three openings to the lagoon, partly because work was slowed by a 2014 corruption scandal that implicated the three main contractors and sent 35 people to jail. Work is continuing largely with the original subcontractors now contracting directly with the consortium, which itself has been placed under government control as a result of the scandal. The fact that the barriers have not yet been physically tested in rough seas is a concern to critics. Paolo Vielmo, an offshore marine engineer who has long criticized the project, said that tests carried out in a laboratory in the Netherlands in the 1990s indicated that the barriers, under certain conditions, would oscillate out of control — possibly even breaking apart. “Its behavior is not predictable,’’ Vielmo said. He said that the trials so far declared successful have been under only modest sea conditions that fail to represent anywhere near the threat of the phenomenon of extreme oscillation called subharmonic resonance. Vielmo and two other offshore engineers have compiled a report for the Codacons consumer and environment protection advocacy group, which is asking officials to run additional calculations to see if the project is indeed viable. And if it is not, Codacons says Moses should be stopped. “We don’t want to delay by one minute the possibility to make Moses operational. But we say we cannot make it operational until we are sure it will work,’’ said Franco Conte, president of Codacons in Venice. “Naturally, the Venetian community is exasperated and they say, ‘If we did 95%, let’s do 100% and see if that works.’ But that is unconscionable. If we don’t know if it works, we cannot experiment.”  The barrier system is made up of giant flood gates, each 20 meters (66 feet) long. The gates are attached by hinges to giant cement blocks placed on the seabed along the three openings from the sea into the lagoon, Malamocco, Chioggia and the Lido. The gates can be lifted to create a temporary barrier in high tides. Once the water has receded, they can be lowered again — allowing shipping traffic to continue and for the tidal system to flush out the lagoon. The idea behind the project was to create a mobile system that would not impede views of the unique and protected landscape. But Moses has suffered criticism from the start that there were simpler, cheaper systems that could have been deployed. Venetians have been waiting since the record 1.94-meter (6.36-foot) flood of 1966 for a system to protect them from regular inundations. The flooding in November, the second-worst recorded, proved the urgency. In the 150 years that they have been recording the tide levels in Venice, two high tides above 1.5 meters have never been recorded in a year. In November, there were three in one week. Climate scientists note that exceptional tides — those over 1.4 meters — have become much more frequent in the past two decades, with more than half of all recorded occurring since 2000. “One has to realize the kind of existential question that that serious flooding has given rise to,” said Jane Da Mosto, an environmental scientist and executive director of the non-profit group We Are Here Venice, which is working to defend the city against myriad issues, including depopulation, cruise traffic through St. Mark’s basin and overtourism. “People are asking: will Venice be defendable against these kinds of episodes?’’  It’s not just the still-uncalculated damage to landmarks like St. Mark’s Basilica, where corrosive salt water creeps through porous brick and tile. It’s also the boxes of ruined belongings and piles of soaked mattresses discarded in alleyways and loaded onto motorboats and trash barges for disposal. The relentlessness of the Venetian fall and winter tides make one-third of ground floors uninhabitable in the historic canal city. “I am very old, I cannot say that I want to die, but I certainly do not want to be witness to the fact that it does not work,” 84-year-old resident Paola Scarpa said of the Moses barriers, as she walked to check on a family property in the Canareggio neighborhood on a recent December morning. “It would be a pain too great.”  ___  Associated Press journalist Trisha Thomas contributed to this report. Claim: Venice tide barriers pass another test but skeptics remain.
Example Output: Floated along by barge , one of the 10-ton barriers designed to relieve Venice’s perennial flooding looks like a giant plaything: an oversized hinged yellow Lego.

Example Input: Paragraph: The Southern Environmental Law Center submitted its response Friday to a two-month test run the Army Corps of Engineers conducted to show it could mechanically replace a small loss of dissolved oxygen in the stretch of the Savannah River being deepened to make room for larger cargo ships. “Overall, it appears that the Test Run report shows that the Oxygen Injection System is capable of delivering oxygen to the river,” law center attorney Chris DeScherer said in a letter to the Army Corps. “However, we remain skeptical that the System will effectively work in perpetuity to mitigate for the impacts of the project.” The Army Corps is spending $100 million to build a pair of stations on the river equipped with large machines that suck in water, swirl it with oxygen pulled from the air and inject the mixture back into the river. The agency plans to run the oxygen injectors indefinitely, roughly from June through September each year when summer heat can cause dissolved oxygen levels in the harbor to drop below minimum standards set by Georgia and South Carolina. The agency estimates it will cost $3 million per year to pump extra oxygen into the waterway shared by Georgia and South Carolina, which is home to endangered shortnose sturgeon as well as species including striped bass and blue crabs. A 2013 court settlement required a successful test before the agency can resume dredging of the 27-mile (43-kilometer) shipping channel that links the Savannah port to the Atlantic Ocean. The project has been on hold since reaching its halfway point in March 2018. The Corps declared last month that tests performed between March and May exceeded expectations. It reported the machines pumped roughly 13,300 pounds (6,070 kilograms) of oxygen into the river daily, beating its target of 12,000 pounds (5,443 kilograms). And it found that on average 95% of the extra oxygen stayed in the water instead of escaping into the air — compared to an 80% target. DeScherer noted the tests were performed during the spring, rather than in summer when dissolved oxygen in the river tends to be lower. And the stretch of river where the machines were tested has yet to be deepened. The legal settlement prohibited deepening that portion of the waterway until after the machines were tested. Conservation groups and South Carolina state agencies had sued the Army Corps in federal court, arguing the harbor expansion would cause irreversible environmental damage. A settlement reached in 2013 stated that the plaintiffs could terminate the deal if the Corps couldn’t prove the oxygen machines worked. DeScherer’s letter said the environmental groups that sued won’t scrap the settlement despite their doubts about the oxygen machines. The deal included other environmental concessions such as $15 million for wetlands protection and $3 million for monitoring endangered fish species in the river. It’s not clear what the South Carolina agencies that were part of the lawsuit will do. A spokesman for the state’s Department of Health and Environmental Control did not immediately return an email seeking comment Sunday. Claim: Groups ‘skeptical’ of Savannah harbor oxygen injector test.
Example Output:
Conservation groups “remain skeptical” that machines injecting oxygen into the Savannah harbor will offset threats to fish caused by deepening the busy shipping channel to the Port of Savannah, but they won’t return to court to fight the $973 million project, according to the environmental groups’ attorney.
