Sharks Are Vanishing From Many of the World’s Reefs
By JoAnn Adkins
A landmark study by Global FinPrint reveals sharks are absent on many of the world's coral reefs, indicating they are functionally extinct — too rare to fulfill their normal role in the ecosystem.
Of the 371 reefs surveyed in 58 countries, sharks were not observed on nearly 20 percent, indicating a widespread decline that has gone undocumented on this scale until now. The Global FinPrint team, led by researchers at Florida International University (FIU), also identified conservation measures that could lead to recovery of these iconic predators.
Essentially no sharks were detected on any of the reefs in the Dominican Republic, the French West Indies, Kenya, Vietnam, the Windward Dutch Antilles and Qatar. Among these, a total of only three sharks were observed during more than 800 survey hours, according to the study published today in Nature.
"While Global FinPrint results exposed a tragic loss of sharks from many of the world's reefs, it also shows us signs of hope," said Jody Allen, co-founder and chair of the Paul G. Allen Family Foundation. "The data collected from the first-ever worldwide survey of sharks on coral reefs can guide meaningful, long-term conservation plans for protecting the reef sharks that remain."
This benchmark for the status of reef sharks around the world reveals an alarming global loss of these iconic species that are important food resources, tourism attractions, and top predators on coral reefs. Their loss is due in large part to overfishing of sharks, with the single largest contributor being destructive fishing practices, such as the use of longlines and gillnets.
"Although our study shows substantial negative human impacts on reef shark populations, it's clear the central problem exists in the intersection between high human population densities, destructive fishing practices, and poor governance," said Demian Chapman, Global FinPrint co-lead, associate professor in FIU's Department of Biological Sciences and researcher in the Institute of Environment. "We found that robust shark populations can exist alongside people when those people have the will, the means, and a plan to take conservation action."
The study revealed several countries where shark conservation is working and the specific actions that can work. The best performing nations compared to the average of their region included Australia, the Bahamas, the Federated States of Micronesia, French Polynesia, the Maldives and the United States. These nations reflect key attributes that were found to be associated with higher populations of sharks — being generally well-governed and either banning all shark fishing or having strong, science-based management limiting how many sharks can be caught.
"These nations are seeing more sharks in their waters because they have demonstrated good governance on this issue," said Aaron MacNeil, lead author of the Global FinPrint study and associate professor at Dalhousie University. "From restricting certain gear types and setting catch limits, to national-scale bans on catches and trade, we now have a clear picture of what can be done to limit catches of reef sharks throughout the tropics."
The FinPrint team is wrestling with the fact that conservation action on sharks alone can only go so far. Researchers are now looking at whether recovery of shark populations requires management of the wider ecosystem to ensure there are enough reef fish to feed these predators.
"Now that the survey is complete, we are also investigating how the loss of sharks can destabilize reef ecosystems," said Mike Heithaus, Global FinPrint co-lead and dean of the College of Arts, Sciences & Education at Florida International University. "At a time when corals are struggling to survive in a changing climate, losing reef sharks could have dire long-term consequences for entire reef systems."
Launched in the summer of 2015, Global FinPrint's data were generated from baited remote underwater video stations (BRUVS) that consist of a video camera placed in front of a standard amount of bait – a "Chum Cam." Coral reef ecosystems were surveyed with BRUVS in four key geographic regions: The Indo-Pacific, Pacific, the Western Atlantic and the Western Indian Ocean.
Over the course of four years, the team captured and analyzed more than 15,000 hours of video from surveys of 371 reefs in 58 countries, states and territories around the world. The work was conducted by hundreds of scientists, researchers, and conservationists organized by a network of collaborators from Florida International University, the Australian Institute of Marine Science, Curtin University, Dalhousie University, and James Cook University.

As we reach the official end of hurricane season, 2020 will be one for the record books. Looking back at these long, surprising, sometimes downright crazy past six months (seven if you count when the first named storms actually started forming), there are many noteworthy statistics and patterns that drive home the significance of this hurricane season, and the ways climate change may have contributed to it.

An unprecedented climate lawsuit brought by six Portuguese youths is to be fast-tracked at Europe's highest court, it was announced today.
The European Court of Human Rights said the case, which accuses 33 European nations of violating the applicants' right to life by disregarding the climate emergency, would be granted priority status due to the "importance and urgency of the issues raised."
‘Protect Our Future’<p>Cláudia Agostinho (21), Catarina Mota (20), Martim Agostinho (17), Sofia Oliveira (15), André Oliveira (12) and Mariana Agostinho (8) are <a href="https://www.desmogblog.com/2020/09/03/youth-climate-lawsuit-portugal-33-european-countries" target="_blank">bringing the case</a> with nonprofit law firm Global Legal Action Network (<span style="background-color: initial;">GLAN</span>), arguing that none of the countries have sufficiently ambitious targets to cut their emissions.</p><p>Portugal recently sweltered through its <a href="https://www.ipma.pt/pt/media/noticias/news.detail.jsp?f=/pt/media/noticias/textos/resumo-clima-julho-20.html" target="_blank">hottest July in 90 years</a> and has seen a rise in devastating heatwaves and wildfires over recent years due to rising temperatures. Four of the applicants live in Leiria, one of the regions worst-hit by the forest fires that killed more than 120 people in 2017. </p><p>Responding to the development, André Oliveira, 12, said: "It gives me lots of hope to know that the judges in the European Court of Human Rights recognise the urgency of our case." </p><p>"But what I'd like the most would be for European governments to immediately do what the scientists say is necessary to protect our future. Until they do this, we will keep on fighting with more determination than ever."</p>
‘Highly Significant'<p>The decision represents a "highly significant" step, <a href="https://www.glanlaw.org/about-us" target="_blank">GLAN</a> Director Dr. Gearóid Ó Cuinn said in a <a href="https://youth4climatejustice.org/" target="_blank">press release</a>.</p><p>"This is an appropriate response from the Court given the scale and imminence of the threat these young people face from the climate emergency," he added. </p><p>By suing the 33 countries all together, the youths aim to compel these national governments to act more aggressively on climate through a single court order, which would potentially be more effective than pursuing separate lawsuits or lobbying policymakers in each country.</p><p>If successful, the defendant countries would be legally bound not only to ramp up emissions cuts, but also to tackle overseas contributions to climate change including those of their multinational enterprises.</p>
‘Major Hurdle’<p>The <a href="https://youth4climatejustice.org/the-case/" target="_blank" rel="noopener noreferrer">countries targeted</a> include all of the European Union member states as well as Norway, Russia, Switzerland, Turkey, Ukraine and the United Kingdom, none of which are currently aligned with <a href="https://www.ecowatch.com/tag/paris-agreement">Paris agreement</a> target to limit global temperature rise to well below 2 degrees C (3.6 degrees F) and pursue a limit of 1.5 degrees C (2.7 degrees F).<a href="https://climateactiontracker.org/countries/" target="_blank" rel="noopener noreferrer"> </a></p><p><a href="https://climateactiontracker.org/countries/" target="_blank" rel="noopener noreferrer">Climate Action Tracker rates</a> most of Europe as "insufficient" in terms of its emissions reduction policies based on the Paris target, while Ukraine, Turkey and Russia are assessed as "critically insufficient" – meaning they are on track for a warming of 4 degrees C or higher.</p><p>The European Union has pledged to slash its emissions by <a href="https://ec.europa.eu/clima/policies/eu-climate-action/2030_ctp_en" target="_blank" rel="noopener noreferrer">at least 55 percent by 2030</a>.
