Amazonas — “I’ve lived on this floating home for 40 years
and this is the worst drought I’ve ever seen
You can see that the water dropped well below the 2023 levels,” says Carlos Magno
as he shows the point reached by the water last year
And it gets even scarier because of the news that this is going to get worse every year.”
Magno is a boat mechanic and lives on a floating house on the water
in the municipality of the same name located in the heart of Amazonas state
While he and his family love living by the lake
they are now considering moving to dry land because of increasingly severe droughts
“The floating house is already completely on land
Take a look here to see how much the water level has dropped
This drought is almost 30 days longer; it usually doesn’t get to this point,” he says
The water needs to rise so Magno can get back to work
a lagoon formation of the Tefé River near the point where it meets the Solimões
has been experiencing a historic drought this year
reaching just 4.5 meters (14.9 feet) — 13.5 m (44 ft) below its June level
when it was 18 m (59 ft) deep (see graph below)
the remaining water recorded extremely high temperatures
reaching 40.3º Celsius (104.5° Fahrenheit)
according to data from the Mamirauá Institute for Sustainable Development (IDSM)
Throughout the Amazon, 69% of municipalities have been recording drought rates that are even more intense than those of 2023 — a 56% increase over the same period last year, according to the Integrated Drought Index (IIS). In Amazonas, the state government’s 2024 Drought Bulletin indicates that another 850,000 people were impacted by lower water levels
and all 62 municipalities are in a state of emergency
According to the Geological Survey of Brazil
the situation could become worse by December
we have observed extreme hydrological events intensifying
with record floods and droughts year after year,” says Ayan Fleischmann
a senior researcher at the Mamirauá Institute’s Research Group on Geosciences and Environmental Dynamics in the Amazon
Monitoring is also carried out by a platform developed by the World Wildlife Fund Brazil (WWF-Brazil) and MapBiomas
which monitors 23 of the more than 60 lakes in the Amazon Basin
It revealed that the waters of lakes connected to rivers have also reached higher temperatures since August
12 of these lakes already have seen temperatures above those recorded in 2023
The data also show that these lakes have had average temperatures above those of the previous year for 5-9 months
which points to physiological stress experienced by living beings repeatedly exposed to high temperatures and low water levels
209 carcasses of pink river dolphins (Inia geoffrensis) and grey river dolphins locally known as tucuxi (Sotalia fluviatilis) were collected
according to researchers from the Mamirauá Institute
an unprecedented mortality event for these species
most of the deaths were related to the overheating of the waters
According to estimates made by the Mamirauá Institute
Lake Tefé is home to approximately 900 pink dolphins and 500 tucuxis
With an annual replacement rate of only 5%
the loss of more than 200 animals in 2023 represented a significant impact on these populations
About 80% of the animals killed that year were pink dolphins
Both species of Amazonian freshwater dolphins are on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species
The pink dolphin and the tucuxi are considered “endangered,” meaning the species will likely become extinct in the near future
This is the second most serious level of threat on the IUCN list
the Chico Mendes Institute for Biodiversity Conservation (ICMBio) and the Mamirauá Institute decided to anticipate the tragedy
“The drought was so intense last year that the river never recovered its level
The expectation was that the tragedy would repeat itself,” says Miriam Marmontel
leader of the Mamirauá Institute’s Amazonian Aquatic Mammals Research Group
team training and acquisition of specific equipment.”
ICMBio established the Tefé Dolphin Emergency in 2023
with technical support from the Mamirauá Institute and in partnership with several institutions
The agency also launched the 2024 Aquatic Fauna Emergency in September
in order to strengthen monitoring of animals in the area and prevent new deaths
More than 50 professionals were in charge of monitoring water conditions and animal behavior twice a day
the dolphin mortality rate was not as expected
helped collect and transport carcasses that often ended up in his backyard
who has worked with dolphins for more than 20 years and has collaborated with the National Institute for Amazonian Research and the Mamirauá Institute
says he believes the animals anticipated an even more severe drought and moved to safer places
“The animals know more than we do; after all
and they didn’t have time to leave the lake
they made sure to leave it earlier,” he explains
what prevented the 2023 tragedy from being repeated was the lower incidence of solar radiation
there were fewer consecutive days of intense sunlight as well as more rainfall and clouds
which prevented the lake from remaining at 40ºC for long periods
“The water temperature in Lake Tefé varies a lot
It can go from 27ºC [81°F] in the morning to 40ºC in the afternoon in a single day
This affects all beings in the aquatic environment but does not result in extreme overheating of its waters,” Fleischmann says
no deaths of dolphins related to thermal stress were recorded
all with signs of contact with human activities such as fishing
The carcasses of these animals are being examined to determine the exact causes of death
But drought is still the element behind the deaths of these animals
aquatic mammals become more vulnerable and are exposed to adverse human activities such as fishing
Sea Shepherd monitors the local fauna in the area of Coari
Although some animals were already in an advanced stage of decomposition
“We found the animals with marks of fishing nets and stab wounds,” Sea Shepherd executive director Nathalie Gil says
the team observed signs of illegal hunting from a distance
“Manatees are the target of excessive hunting
with 15-20 animals caught every day,” Gil says
The Amazonian manatee is one of the 1,182 Brazilian species threatened with extinction
They are listed as “vulnerable” on the Official List of Endangered Species of Brazilian Fauna
Although dolphins are not directly targeted by hunting
they are engaged in a battle with the local fishers
According to fisherman Edinei de Lima Ferreira
pink dolphins are “lazy.” They wait for the gillnet
to fill with fish so they can rip it open and eat
“We work so hard to mend the net and put it in the river
and then that animal comes and rips everything
walking around the city of Tefé or sailing along the rivers
it is possible to see that the tension between dolphins and fishers is serious
who has years of experience with the species
says it is rare to find someone in the area who likes dolphins
There is also fear of the legends that say the dolphins may cause harm.”
pinks dolphins are known for their mystical ability to seduce
the animal emerges from the rivers as an attractive man capable of conquering a young woman and impregnating her before returning to the waters
It is now known that the legend of the pink dolphin is strongly linked to cases of sexual violence in the area
which were killed for fear of their supposed powers of seduction
There are also reports that dolphin parts were worn as amulets and that the animal’s fat was used for medicinal purposes
While the legend is no longer the main reason for hunting
retaliatory capture still occurs in some places
In the struggle between fishers and dolphins over fishing resources
the resentment of the former has been drawing researchers’ attention
sound devices are being developed that keep dolphins away from fishing nets
preventing both the destruction of gillnets and retaliation against the animals
together with the Society for Environmental Research and Protection
began testing this technology in June 2023 at the Prainha I community
there was a 40% reduction in damage to gillnets and a threefold increase in the amount of fish caught
effectiveness decreased in the second phase of testing
when the dolphins began to adapt to the noise and find new ways of approaching
a researcher at the Aquatic Mammals Center
were originally designed for the marine environment and that their adaptation for use in rivers requires significant adjustments
Getting people to adopt the technology is another challenge
who fear that their catches will decrease with the use of these devices
and adapting these technologies in an accessible way is still difficult.”

the Brazilian Amazon is infinitely important to biodiversity conservation
and to the communities who live there and are sustained by its bounty
Working to protect as much as possible of this irreplaceable tropical biome before it is lost is a top priority for Rainforest Trust
traveled to the heart of the Brazilian Amazon to visit communities deeply involved in conservation efforts in the region
where Rainforest Trust has supported our partner
Instituto Internacional de Educação do Brasil (IIEB)
to safeguard 1,280,981 acres of primary rainforest within the buffer area of the 2.5-million-acre Tefé National Forest Protected Area adjacent to Lake Tefé
a well-developed town with a commercial airport
they traveled over 60 miles by boat to visit four communities living in the Tefé rainforest
“Our recent trip to Tefé left a lasting impression,” Andrea reports
“James Lewis and I had the privilege of meeting with the eight Community Council leaders and I was deeply moved by the remarkable work they are doing to safeguard the Amazon forest while navigating the complex process of land tenure regularization
“It’s always great to hear from individuals,” James said
“So often we’re involved in high-level discussions about policy
Actually being able to meet in person and connect the people themselves and their personalities and experiences with the conservation that we’re helping achieve
And I know it is meaningful for our donors to hear from local people as well.”
The Lake Tefé project is an excellent example of how Rainforest Trust supports partners working towards formal government recognition of the land tenure rights of Indigenous and traditional communities—a status that also grants them the power to manage and protect their lands
as communities in the Amazon are facing unprecedented challenges and threats to their survival
James and Andrea heard from those they visited about the devastation caused by the extended drought of 2023 that hit the Amazon and nearly dried up Lake Tefé—a lake that measures 50 to 65 feet deep in its deepest spots
No one in the villages they visited had living memory of the lake ever drying up before
“One of the most striking sights was the Tefé Lake
which was at its fullest during our visit,” said Andrea
“It was hard to imagine that just months earlier
this massive body of water had nearly dried up
causing immense destruction and despair for both nature and the people who depend on it
but the memory of that crisis still lingers.”

The famine that followed the drought reverberated across the Amazon
the traditional fishing livelihoods of the people were lost for the season
Their only means of transportation—the rivers—became unnavigable
with dramatically lower fish stocks this year due to the devastating losses last year
the dry season has started earlier than ever
fueling dire predictions of another drought for a region already reeling from major changes to the global climate
This is a trend that is being amplified across the entire Amazon basin each year as the effects of climate change are growing

Though the rainforests here have been inhabited for generations by traditional communities of fishermen
Brazilian nut gatherers and rubber tappers
their lives and livelihoods are increasingly threatened by criminal activities due to the lack of clear land ownership rights
Lake Tefé communities are also impacted by unregulated tourism spreading from its shores
given the region’s astounding beauty
To address the urgency of Amazon conservation
Rainforest Trust created the Brazilian Amazon Fund in 2023 to raise $40 million to permanently safeguard 20 million acres of intact forest—an expanse the size of South Carolina—as new protected areas and Indigenous territories
These projects will also safely lock up 6 billion metric tons of CO2 equivalents (more than the U.S.’s annual total CO2 emissions)

Severe drought and soaring temperatures are causing lakes and rivers in the Amazon to reach dangerously high temperatures, threatening species like the Amazon river dolphin, according to a recent study’s preprint
In 2023, the Amazon experienced its worst drought in recorded history, coupled with the hottest dry season on record
The extreme climate caused the surface area of Brazil’s Tefé Lake to shrink by approximately 75%
with vast sections of the lake reduced to less than 1 meter (3.3 feet) in depth
As air temperatures peaked at 39.1° Celsius (102° Fahrenheit)
the little water that remained in the lake quickly overheated
The average surface water temperature for tropical lakes is around 30°C (86°F)
the researchers found that the entire water column
leaving no refuge for animals seeking cooler temperatures
The study focused on Tefé Lake because of the mortality event observed the same year
when more than 200 endangered Amazon river dolphins (Inia geoffrensis) and tucuxi dolphins (Sotalia fluviatilis) perished
The researchers say the deaths were likely caused by the extreme water temperatures that year
The scientists caution that with ongoing climate change
temperatures that exceed heat tolerances for aquatic species will become more common
Five out of the 10 lakes examined in the study had exceptionally high daytime temperatures
long-term warming trend in Amazonian waters
Satellite data show that the region’s lakes have warmed by an average of 0.6°C (1.08°F) per decade over the past 30 years
This decadal temperature rise “is a notable increase compared to global averages for lake warming,” Iestyn Woolway
an independent research fellow with Bangor University
“This data is critical as it provides a regional perspective that has often been overlooked in broader climate studies.” Woolway was not involved in the study
Woolway added that the models used to simulate the conditions on Tefé Lake are robust
but on-site data collection would be more precise
a limitation the study’s authors also acknowledge in the paper
“Overall this study focuses on a specific event in a particular region
more research across different tropical freshwater systems is needed to understand their broader implications,” Woolway said
The study has been submitted for peer review and preliminary data were presented at the annual meeting of the Brazilian Society for the Advancement of Science

Brazil – 16 October 2023 – At least 140 endangered dolphins have died and hundreds are still trapped as Lake Tefé in the Amazon rainforest in Brazil suffers from historic drought and high-water temperatures
Marine mammal stranding experts from IFAW arrived in Tefé on Sunday at the request of the Mamiraua Institute for Sustainable Development (Instituto de Desenvolvimento Sustentável Mamirauá). This trip is made possible in part by a generous contribution from the Dutch Postcode Lottery (Nationale Postcode Loterij)
“We commend the teams on the ground in Brazil for all they have been doing to understand
and prevent further suffering of these animals,” said Dr
we are not without hope that we can help identify solutions that will result in a positive outcome for the surviving dolphin population.”
the hope is to give these animals the best chance of survival
Sharp and animal rescue responder and biologist Kira Kasper to work with local agencies
and bring the kind of fresh thinking and solutions the team is known for
Amazon and Tucuxi river dolphins are already endangered
and the impacts of climate change likely be worsening their fate
“With the dry season expected to peak in the next two weeks
the worst might be yet to come,” said Kasper
these animals will continue to be stressed and in need of aid
We are coming prepared with the supplies to hopefully face any challenge we may encounter on the ground.”
The IFAW team will spend at least two weeks in Tefé
They will assess the situation and rescue options for up to 400 Amazon river dolphins and Tucuxi dolphins that are trapped in shallow
The two IFAW experts will work with local rescuers to better assess the situation
The team will bring with them specialised equipment including stretchers
The IFAW team is committed to helping as many dolphins as possible
as every individual animal matters to the survival of the population
IFAW is a global leader in rescuing marine mammals with its Marine Mammal Rescue & Research team celebrating its 25th anniversary this November
US—an area that sees the most frequent live strandings of dolphins than anywhere else in the world
It’s with this 25-year history of research
and hands-on experience that IFAW has been called upon for consultation and training in over 16 countries
the Dutch Postcode Lottery awarded a grant of €1.5 million Euro to support a new IFAW marine conservation and rescue project
The project seeks to optimise post-release survival rates of stranded cetaceans through enhanced global rescue
and release activities while reducing human-caused threats to ensure marine mammals are released back into safer and more secure habitats

A severe drought has thrown the Brazilian Amazon into an emergency
with water levels in rivers and lakes across the basin falling to unprecedented lows in September
This has restricted the movement of people and goods by boat
making it even more difficult for remote communities to access health and education facilities
and left thousands of people facing water and food shortages
This scenario could worsen dramatically by the end of October
when the drought is expected to be at its most severe
The Amazon typically receives less rainfall during this current time of year
But the 2023 dry spell has been exacerbated by two simultaneous natural events that inhibit cloud formation
further reducing the already low rainfall in the region
the abnormal warming of the surface waters of the equatorial Pacific Ocean
which produces east-to-west air currents over the Amazon Rainforest
Another factor is the warming of the waters of the northern tropical Atlantic Ocean
which creates north-to-south winds across the biome
These air currents are an obstacle to the formation of rain clouds
“With the two phenomena acting simultaneously
we have a more intense drought that also affects a larger area of the Amazon biome,” Renato Cruz Senna
a meteorologist and researcher at the National Institute for Amazonian Research (INPA) in Brazil
The critical level of the Amazon’s rivers is a major problem
River navigation is the primary transportation method across the world’s biggest rainforest
and the only means of access for many communities
especially in the western part of the biome
The flow of boats on the great rivers — the Amazon
Purus and Juruá — supplies the entire region with essential goods sent from other parts of Brazil
from food items like beans and beef to materials like cement and iron
The same routes are used to transport commodities
from televisions and bicycles produced in the Manaus Free Trade Zone
Authorities say 90% of regular vessels are now operating with some kind of restriction in the state of Amazonas
which has ordered cargo capacity to be halved
1,120 kilometers (700 miles) from the Amazonas state capital Manaus
It sits at the confluence of the Solimões and the Javari
the river that forms the border between Brazil and Peru
Water levels here have receded so much that huge sandbanks have emerged in the middle of the rivers
even to the neighboring municipality of Tabatinga
with the risk of total shortages if the river continues to recede,” David Bemerguy
“It’s the worst drought ever seen here because the river has more sandbanks
In addition to the shortage of drinking water
the municipality of 37,000 inhabitants faces a growing public health problem
“We have worsening respiratory diseases
and other health problems associated with the drought
We depend on a river connection to help patients
The current situation is unthinkable,” Bemerguy said
On Sept. 26, the Brazilian federal government released $41 million reais ($8,2 million) to dredge 8 km (5 mi) of the Solimões and reestablish the link between Benjamin Constant and Tabatinga
Benjamin Constant is just one of 60 municipalities across Amazonas, out of the total of 62 in the state, that are currently suffering from the effects of the drought. Manaus
In Porto Velho, the capital of Rondônia state, the Madeira River hit its lowest level in September. With their wells running dry, people living along the river are traveling up to 30 km (19 mi) to buy freshwater, according to news outlet G1
At least 15,000 people are suffering from water shortages on the banks of the Madeira
Amid the severe drought, more than 100 Amazonian dolphins, including endangered species like the pink river dolphin (Inia geoffrensis) and the tucuxi (Sotalia fluviatilis), were found dead in Lake Tefé
“I’ve never seen anything like this,” Miriam Marmontel
an Amazonian aquatic mammal researcher at the Mamirauá Institute
“It’s a huge die-off of dolphins in a localized area due to high temperatures
We’re worried because these are two endangered species
charismatic animals that are symbols of the Brazilian Amazon.”
Many other lakes and rivers in the Brazilian Amazon have already recorded large numbers of dead fish due to the drought
The dry season in the Brazilian Amazon began earlier than expected and has been more severe than in previous years
Weather forecasts indicate the drought conditions will likely last longer in 2023
“We will have low-intensity rains from October onward due to El Niño,” Sidney Abreu
from the Brazilian National Institute of Meteorology (INMET)
“This rainfall deficit should last until the second half of December
river levels in the Amazon will likely take longer to return to normal
prolonging navigation problems in the region
Mongabay received a forecast of flows for the next three months from Ana Paula Cunha
a drought researcher at the National Center for Monitoring and Early Warning of Natural Disasters (CEMADEN)
The data show flows well below average throughout the region
New restrictions on navigation are expected in the coming weeks
president of the Brazilian Association of Cabotage Shipowners (ABAC)
which represents companies that transport cargo along the rivers in the Amazon Basin
“With depth restrictions to avoid hitting sandbars
ships are carrying less cargo than they could
That makes freight more expensive,” he told Mongabay by phone
“Everything suggests that we will have to reduce cargo even more as the rivers recede
which means fewer products with higher prices in the region
The greatest impact will be felt in the supermarket,” he said
According to Senna, the INPA researcher, river levels in the Amazon may reach record-low levels in late October
“The level of the Rio Negro is dropping by 1 meter [3 feet] every three days
something that has never been recorded before,” he told Mongabay
He said communities living in the Amazonian region have become used to intensive flooding
but aren’t as resilient to the effects of severe droughts
“It’s a very chaotic process for the region
When rivers and lakes can’t be navigated
the population suffers all kinds of restrictions
The drought that is predicted for the region in 2023 is unprecedented.”

Pete is following the mighty Amazon river in the most ambitious and intimate way possible: walking
sometimes swimming every inch of the Amazon from sea to source
and in the process interacting with its people and its wildlife face to face at ground level
It would have been much quicker walking along the exposed banks of the Solimões (Amazon) river, but the risk of encountering river pirates was very high – so for this latest section, Coari to Tefé
and cut our own path through the longer and tougher inland jungle route
paying the guides and getting them back home
with all the logistical nightmares to overcome
Even if the toughest part physically and mentally is the walking
it is always a relief to actually get started each time on a new leg
it is difficult to condense a month’s eventful jungle traverse into a single blog post
and I had very welcome boat support from the local community
especially when a group of river dolphins decided to join us and swam alongside all the way across the largest – 7 kilometre – section of the lake
Erland swam more than half the leg with me
while Jhonatan filmed from the support canoe and looked after the backpacks
The luxury of having a whole team on the job
we were advised to avoid entering/passing certain communities near to the Solimões
if only because I had planned to resupply at these points
We had an unplanned 6 kilometre armed escort out of one of the communities for our own safety after buying food supplies
Our escort was courteously arranged free of charge by the local indigenous reserve manager
once again I have to add that all the people we had contact with were unbelievably hospitable
We were even given an empty house to sleep in
“If a tree falls in the rainforest and nobody’s there to hear it
Well without getting into philosophy or the science of sound-waves
perception and observation …..I can confirm that if you do happen to be in the vicinity
a falling tree in the middle of the rainforest makes a sound that’s pretty damned loud
when all the animals and insects go quiet for at least 7 seconds
the animals are always there to hear it!) We were all awakened one night when a large tree fell very close to our camp during a storm
with one of the branches crashing through the fly sheet that protects the fire from rain
Falling trees and branches (branches some the size of a bus) are one of the dangers of jungle walking that is quite unpredictable
so the best we can do is keep our fingers crossed while walking
and avoid making camp near old or leaning trees with overhanging dead branches
young healthy trees also fall victim to a sudden intense gust of wind during tropical downpours
and we have clambered over and under clusters of freshly fallen
but it seems there is the possibility of another member of the family walking with me on the next leg to Fonte Boa
We did have to put in some long,tough 9-hour walking days
as the guides were determined to get home for Natal (Christmas) to be with their respective families
and the 230 kilometre crossing took 27 days in all – but it was an inspiring experience
and we slept with full bellies every night
The rising water levels and the beginning of the rainy season will make the going much tougher
But with more and more first-hand experience under my belt/backpack
I find my understanding of the terrain – it’s topography
Perhaps I’m finally beginning to really understand the lay of the land

A fisherman stands on his boat as he navigates near thousands of dead fish awash on the banks of Piranha Lake due to a severe drought in the state of Amazonas
SAO PAULO — More than 100 dolphins have died in the Brazilian Amazon rainforest in the past week as the region grapples with a severe drought
and many more could die soon if water temperatures remain high
a research group of Brazil's Ministry of Science
said two more dead dolphins were found Monday in the region around Tefe Lake
which is key for mammals and fish in the area
Video provided by the institute showed vultures picking at the dolphin carcasses beached on the lakeside
Experts believe high water temperatures are the most likely cause of the deaths in the lakes in the region
Temperatures since last week have exceeded 39 degrees Celsius (102 degrees Fahrenheit) in the Tefe Lake region
The Brazilian government's Chico Mendes Institute for Biodiversity Conservation
said last week it had sent teams of veterinarians and aquatic mammal experts to investigate the deaths
There had been some 1,400 river dolphins in Tefe Lake
"In one week we have already lost around 120 animals between the two of them
which could represent 5% to 10% of the population," said Marmontel
Workers have recovered carcasses of dolphins since last week in a region where dry rivers have impacted impoverished riverside communities and stuck their boats in the sand
Wilson Lima on Friday declared a state of emergency due to the drought
said his government was unable to deliver food directly to some isolated communities because the rivers are dry
the Geospatial coordinator at the Mamirauá Institute
said the drought has had a major impact on the riverside communities in the Amazon region
which is their main means of transportation," he said
Fleischmann said water temperatures rose from 32 C (89 F) on Friday to almost 38 C (100 F) on Sunday
He said they are still determining the cause of the dolphin deaths but that the high temperature remains the main candidate

worried experts said.Environmental activists have blamed the unusual conditions on climate change
which makes droughts and heat waves more likely and severe
Global warming's role in the current Amazon drought is unclear
with other factors such as El Nino at play."We have documented 120 carcasses in the last week," said Miriam Marmontel
a researcher at the Mamiraua environmental institute that focuses on the mid-Solimoes river basin.Roughly eight of every 10 carcasses are pink dolphins
which could represent 10% of their estimated population in Lake Tefé
she said.The boto and the gray river dolphin called the "tucuxi" are on the International Union for Conservation of Nature's red list of threatened species"Ten percent is a very high percentage of loss
and the possibility that it will increase could threaten the survival of the species in Lake Tefé," Marmontel said.Brazil's Chico Mendes Institute for Biodiversity Conservation has rushed veterinarians and aquatic mammal experts to rescue dolphins that are still alive in the lake
They cannot be moved to cooler river waters until researchers rule out a bacteriological cause of the deaths.Reporting by Bruno Kelly; Writing by Anthony Boadle; Editing by Brad Haynes

Before-and-after photos published over the weekend reveal the severity of a drought plaguing the Amazon that has depleted several lakes and rivers
but the impacts have been exacerbated by climate change—resulting in low water levels that have devastating impacts
The drought has stranded some of the Amazon's river communities
leaving people without access to desperately needed supplies
with several marine species dying from its impacts
a researcher shared four satellite photos that showed the steep decline in water levels at Lake Tefé
"40 days of the extreme drought in Lake Tefé, Central Amazon," Ayan Fleischmann posted on X, formerly Twitter
Fleischmann is a researcher at the Mamirauá Institute for Sustainable Development
40 days of the extreme drought in Lake Tefé, Central AmazonSource: Planet satellite imagery pic.twitter.com/gRSBrjzr5l
Newsweek reached out to Fleischmann by email for comment
Lake Tefé can be seen full of blue water
The water level has fallen substantially over a 40-day period
and the last photo shows a nearly dry lakebed
The low water levels are causing fatal impacts, as 153 river dolphins—or 10 percent of the lake's population—died over a week after Lake Tefé's water temperatures soared to 102.38 Fahrenheit during the last week of September. The dolphins were found dead by the dozens
with 130 pink dolphins and 23 tucuxi dolphins affected
the lake's water temperature is around 89.6 degrees F

Hundreds of fish were also killed in the Rio Negro due to low water levels and high temperatures
The fish were contaminating the water source and also signaled that more ominous impacts would take place if the drought continued

More than 100 dolphins have died in a Brazilian Amazon lake because of drought and water temperatures up to 39˚C (102˚F)
Dolphin bodies have been emerging from Lake Tefé for the last few weeks, researchers from the Brazilian Ministry of Science-funded Mamirauá Institute told CNN
While wet and dry seasons are a normal part of the Amazon River’s ecology
the extreme drought soaring water temperatures are unusual
The Guardian reported that thousands of dead fish have also risen to the surface of Lake Tefé in recent days
“The past month in Tefé has seemed like a science-fiction climate-change scenario,” British researcher Daniel Tregidgo told the paper
“Regular sightings of pink river dolphins are one of the great privileges of living in the heart of the Amazon
Pretty much every time I go to the market to have breakfast
I see them come to the surface and it reminds me why I live here
knowing that this drought has killed over 100
Lake Tefé and the surrounding watershed is experiencing lethally warm water temperatures
The two primary factors behind the lethally warm water are the shallow river depth and unseasonably warm air
The water level in some parts of the river is almost half the depth that it should be at this time of year
The pink river dolphin, known locally as a boto, is one of six remaining freshwater dolphin species worldwide. The International Union for the Conservation of Nature classifies the cetaceans as endangered
Brazillian officials and volunteers are currently trying to relocate distressed dolphins to the main river channel where water temperatures are cooler
but the work is delicate and time-consuming
“Transferring river dolphins to other rivers is not that safe because it’s important to verify if toxins or viruses are present [before releasing the animals into the wild],” Mamiraua Institute researcher Andre Coelho told CNN

Some 153 dolphins have died in a single week in a Brazilian lake
10 percent of the lake's entire dolphin population
The Lake Tefé dead were made up of 130 pink dolphins and 23 tucuxi dolphins
both of which have declining populations and are listed as "endangered" on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species
"What is happening at Lake Tefé is appalling
The impact of the loss of these animals is enormous and affects the entire local ecosystem"
Pink river dolphins, also known as Amazon river dolphins, are the largest species of river dolphin
These dolphins gain their characteristic pink color from repeated abrasion of the skin during aggressive interactions with others of their species
"Scientists are working now to try to understand the problem specifically
however we know in mammals that high temperatures stress out the animals' physiology by bringing them out of what's called their 'thermal neutral zone'
This is the set point of the body where metabolism has to rise to keep the animals' body temperature constant," Jason Bruck
an assistant professor of biology at Stephen F
"At some point these animals are just not adapted to swim in 102 F waters."
The water in Lake Tefé was tested by local environmental consultancy Aqua Viridi
who found a large amount of algae Euglena sanguinea
This algae makes a toxin that often kills fish
necropsies on the dolphins did not reveal that the algae or its toxins caused their death
meaning that the driver of the mass death is likely the abnormally warm water temperatures
"The river dolphins were in shallow waters that with sunlight and little or no rainfall made water temperatures become very hot," Patricia Charvet
a professor of aquatic biology at the Universidade Federal do Ceará in Brazil
"By being aquatic mammals, water helps keep their body temperatures within their physiological tolerance levels. Most aquatic fauna from the Amazon Region tolerates higher water temperatures when compared
there are limits in terms of water temperature they can endure
"Sometimes strandings in closed lakes can do this (water levels go down and the connection with the main river channel is lost
leading to shallow lakes with overheated waters)."
The extreme drought in the region has also led to dramatic declines in water levels
which is devastating for communities that use the waterways as major routes of transport: the city of Manaus
the capital of the state of Amazonas at the junction of the Amazon and Negro rivers
reached its lowest water levels in 121 years on Tuesday
"The Amazon Region is facing one of its worst droughts in history due to an extremely strong El Niño phenomenon," Charvet said
weather experts started alerting that waters from the Pacific Ocean were becoming abnormally hot (much warmer than expected) and warned that they were probably looking at one of the strongest El Niño events ever recorded
the El Niño is causing extreme droughts in the mid to west Amazon Region (mainly Manaus and westwards)."
Conservation efforts at Lake Tefé are attempting to prevent further dolphin casualties from the heat
physically blocking off of the hottest regions of lake and moving the remaining dolphin to deeper
"We formed a huge coalition to help collect carcasses
monitor live animals in critical areas of low depth and high temperatures
collect and send biological and water samples for analysis
An entire effort to get to the root causes of this unprecedented event," Frias said
we found that they suffer from various pressures
mercury contamination and the impact of hydroelectric plants
But these events in Tefé show that more research needs to be carried out on how they will be affected by constant climate change."
the dolphins will remain at risk of similar events like this happening again
"In the long run the deaths of these river dolphins is associated with climate change
the changes we are causing throughout the world will likely impact more specific environments/ecosystems
altering rainfall and hydrologic water balance
deforestation is also contributing to temperature increases (land
air and water) in the Amazon Region but the overall scenario is an extreme drought caused by little or no rainfall associated with the El Niño phenomenon," Charvet said
"Perhaps it's time for some faster changes regarding climate change prevention to avoid other deaths."

have been discovered lifeless in a tributary of the Amazon River in Brazil
These unique dolphins are already considered threatened species and are listed on the IUCN Red List
Experts believe that the severe drought and scorching temperatures in the Tefe Lake region are the likely causes of this tragic event
The water temperatures in the area exceeded 39°C (102°F) in recent days
creating a hostile environment for these delicate creatures
thousands of fish have also died due to these harsh conditions
Miriam Marmontel, a researcher at the Mamiraua Institute, while talking to Al Jazeera
noting that nearly 80% of the discovered carcasses are pink dolphins
locally known as "boto." This significant loss poses a threat to their population in Lake Tefe
Scientists are currently investigating the cause of this surge in dolphin mortality
including the possibility of bacterial infections
a distressing pattern emerged as a significant number of carcasses appeared when Lake Tefe's water temperature reached an unprecedented 39°C
more than 10 degrees above the usual average for this season
water temperatures again rose to 37°C (99°F) recently
Brazil's Chico Mendes Institute for Biodiversity Conservation has promptly taken action
deploying veterinarians and experts to rescue any surviving dolphins in the area
While the exact cause is still under examination
environmental activists have pointed to climate change as a contributing factor
making droughts and heatwaves more severe and frequent

it will take people with a good sense of responsibility to do what is right and what is expected of them
Rev Ganyo who was speaking at the 2021 Presbytery Representatives Conference of the Tema Presbytery of Global Evangelical Church at Tema said the Global Evangelical Church is focused at discipling its members and citizens to take up responsible positions to move the country forward
He explained that when people are discipled
they become responsible for tasks and responsibilities that have been assigned them
"We want our members to be responsible such that when you assign them with duties
you have confidence that it will be executed perfectly even in your absence," he said
The Presbytery Chairman mentioned that the church must participate actively in the nation-building process
and one of such ways was to develop and raise godly citizens
He urges members of the church to avail themselves to discipleship and take up responsible positions in building the country
Rev Ganyo revealed that though the year 2020 will go down in history as an eventful year with the outbreak of the coronavirus pandemic
the Church remains resolute in ensuring that members are steadfast as they observe the safety protocols
He mentioned that the Church is doing all it can to bring congregations together as the peak time of the COVID-19 put many members apart
Reverend Ganyo said it is the Church’s aim to disciple many to take responsible positions in the growth of the nation
The Presbytery Conference is aimed at taking stock of the previous year and chart a new course for members and the Church in the ensuing year
“Faithful Stewardship” marks the beginning of a four-year term for the new executives
