Harmful algae can ruin your beach vacation…or even kill you

Global algae and seaweed blooms

Fouled oceans, lakes and rivers

Toxic seaweed and algae blooms are rapidly becoming a major environmental, economic, and public health problem worldwide. Driven by global warming and industrial agriculture waste, these incursions are comprised of cyanobacteria (“blue-green algae”), seaweed and other invasive aquatic species as they increasingly propagate exponentially and engulf coastal regions. 

These noxious aquatic species aren’t new to our planetary habitat. Under normal conditions, they are natural components of aquatic environments. What happened to change thngs is that humans have provided conditions that are warmer and warmer and full of phosphate or nitrogen runoff. Mmmm. That’s good stuff.

In locations from these blooms can: mess up a coastline or beach for extended periods, fouling the area, killing animals and stinking up the place. Some species are so toxic as to be deadly, such as the incident that killed a man in Brittany.

Global warming and agricultural nutrients pollution:

Both drivers of global algae incursions are directly caused by human activity:

Rapidly heating oceans and lakes provide a hothouse environment in which these aggressive organisms thrive. The warming of the oceans – which continues to accelerate – strengthens marine heatwaves, alters ocean circulation, increases heavy rainfall and runoff and (surprisingly) expands stratified warm surface layers where algae thrive.

In addition to the hothouse environment, humans are providing 24/7 dining for cyanobacteria and various seaweed types. 

Industrial scale agriculture is not exactly Old McDonald’s farm, as it spews massive amounts of excess nitrogen and phosphorus from fertilizers, livestock waste, sewage and Industrial runoff. 

Industrial agricultural pollution drives global algae production

Algae on Australia beach

Australia’s unsolvable algae menace driven by unrelenting marine heatwave

A harmful algal bloom (HAB) event that started in March 2025 is ongoing along the coasts of the state of South Australia as of May 2026. It has caused fish kills impacting the marine environment and associated fishing and aquaculture industries, as well as beachgoers and tourism operators along the affected coasts. The extent and duration is unprecedented in both South Australia and Australia, and is probably one of the top ten recorded blooms in the world

Brittany seaweed incursions have killed dozens

The Brittany coastline is famed for its green hills, rugged cliffs and miles of sandy beaches. But over the past few decades, in places, the sand has begun to disappear beneath a carpet of green goo. At certain times of year, when Ulva armoricana, a type of seaweed, blooms, banks of green mass form on the beaches, releasing hydrogen sulphide, a foul-smelling, potentially harmful gas. In recent years, red and yellow warning signs have appeared on stretches of the coastline. And dozens of visitors have died when exposed to the gases emitted by the algae mass.

Gulf of Mexico Dead Zone

Gulf of Mexico Dead Zone one of hundreds expanding globally

Every summer, a low-oxygen area, often referred to as a Dead Zone, develops off of the Texas-Louisiana shelf when nutrient-laden fresh water from the Mississippi and Atchafalaya Rivers flows into the Gulf of Mexico.

Dead zones are areas of water bodies where aquatic life cannot survive because of low oxygen levels. Dead zones are generally caused by significant nutrient pollution, and are primarily a problem for bays, lakes and coastal waters since they receive excess nutrients from upstream sources..

Global Atmospheric CO2 crosses 431

LET’S CLEAR THIS UP: SOME YEARS, CO₂ LEVELS RISE MORE SLOWLY, BUT THEY ARE STILL RISING. CONCENTRATIONS REMAIN IN THE ATMOSPHERE FOR 300 TO 1,000 YEARS.

Based on the misinformation we are fed, we can be forgiven for thinking levels of CO₂  in the atmosphere are decreasing. They ARE NOT. They are increasing.  Some years CO₂ rises more slowly than others, but the overall concentration is still going up. There was a reduction of U.S. emission in 2023 and 2024 but that ended in 2025. A reduction of emissions does not equal a reduction of existing levels. In addition to monstrous and growing AI power demands, the geopolitical situation has reversed the illusion of real progress.

MAY UPDATES: GLOBAL CLIMATE CATASTROPHES

The daily average concentration of atmospheric CO2 at Mauna Loa Observatory first exceeded 400 PPM on 10 May 2013. Now it’s 431 PPM.

The quantity of CO2 in the atmosphere hit a record high in April 2026. Carbon Dioxide levels averaged about 431 PPM (parts per million) over that month, according to data collected at NOAA’s Mauna Loa Observatory in Hawaii. The Trump administration is about to close the facility. further eroding climate science in the US.

The daily average concentration of atmospheric CO2 at Mauna Loa Observatory first exceeded 400 ppm on 10 May 2013.

In 1958, the observatory reported COlevels of 320 PPM.

Feel free to do the math.

Twice the size of Texas, this toxic human-made aberration is worse than previously thought

Map of gyres centered near the South Pole (click to enlarge)

The Great Pacific Garbage Patch (or Pacific Trash Vortex) is a 620,000 sq mi, partially submerged mass of marine debris in the North Pacific Ocean, bounded by the massive North Pacific Subtropical Gyre.

Micro plastics damage plankton and marine ecosystems 

Healthy oceans help cool the planet by absorbing carbon dioxide. Tiny organisms like phytoplankton remove CO₂ through photosynthesis.

Plastic pollution can:

  • injure marine life
  • transport toxins
  • disrupt food webs
  • reduce plankton health and productivity

As ocean ecosystems become less effective at storing carbon, more CO₂ stays in the atmosphere, increasing warming.

_____________________________________________________________________________________________________

*  Black Carbon: Or “soot,” is a type of fine particulate air pollution formed by incomplete combustion, for example of wood, waste and fossil fuels. It creates carbon dioxide (CO2), carbon monoxide, and volatile organic compounds, warming the atmosphere because it is very effective at absorbing light. It exacerbates warming of the air and surfaces in regions where it is concentrated, altering weather patterns and ecosystem cycles.

 

TV cameras can’t see it, so it doesn’t make the news

A new study shows that the massive gyres of plastic waste floating in the Pacific (as in twice the size of Texas) are also contributing to planetary heating. The two floating continents of toxic marine debris are alarming enough in terms of the ecological havoc they wreak. The new research from  Fudan University in Shanghai shows that colored microplastics suspended in the atmosphere over the gyres may contribute more to global warming than previously understood, with some regions near ocean garbage patches showing warming effects greater than black carbon. 

The Great Pacific Garbage Patch contributes to planetary warming in direct and indirect but ways. It’s not a giant “hot spot” that radiates heat like a power plant, but the plastic pollution inside it affects the climate system by generating greenhouse gases. The amount of  ongoing marine ecosystem damage is incalculable.

Sunlight makes plastics release greenhouse gases

As plastics float in the ocean and break down under UV sunlight, they outgas methane (CH4), ethylene and other hydrocarbon gases.

These gases trap heat in the atmosphere. Researchers have shown common plastics like polyethylene emit more gases as they weather in sunlight. The degree of warming from these sites is not as significant as industrial and agricultural sources, but represent yet another contribution factor.

Dark debris changes ocean heating

Large concentrations of floating trash alters how sunlight interacts with the ocean surface, as darker or debris-covered surfaces may absorb more solar energy. The report suggests it may be more damaging than *black carbon events. 

Micro plastics are part of the ever growing pollution affecting every phase of our existence

Most of the debris in the patch is plastic derived from oil and natural gas. which releases large amounts of greenhouse gases such as carbon dioxide and methane. It’s all part of the global fossil-fuel-based plastic economy:

  • extracting oil and gas
  • transporting them
  • manufacturing plastics
  • shipping products worldwide

Each stage emits heat-trapping gases into the atmosphere.

Cleanup and degradation releases additional emissions

As plastics fragment into microplastics and nanoplastics:

  • cleanup operations use fuel and energy
  • degradation processes may release more greenhouse gases over time
  • burning collected plastic waste can emit CO₂ if not handled carefully

 

 

 

Rivers of the Arctic run orange with sulfuric acid and other toxins

 

GLOBAL WARMING IS DEGRADING POLAR PERMAFROST, RELEASING heavy METALS, TOXINS AND METHANE LONG STORED BENEATH THE TUNDRA.

Across Alaska and other parts of the Arctic, dozens of once-clear streams and rivers are turning a nasty rusty orange. As documented by NOAA’s 2025 Arctic Report Card, the new phenomenon was evident in over 200 watersheds in the region. The visual result in similar to the waste water generated in waterways by unregulated mining. Images show 

As temperatures rise, permafrost frozen for thousands of years is thawing. The heavy metals, acids and viruses trapped below the tundra are quickly leaching into once pristine waterways. Researchers describe the phenomenon as similar to acid rock drainage that occurs in mining regions. The “rusting” reflects fundamental chemical changes in watersheds systems, as once frozen ground and minerals become exposed to oxygen and water. 

This accelerating scenario represents a grave threat to marine life, wildlife and drinking water for the indigenous people of the region. But the thawing of permafrost has any number of additional consequences, including methane blowout craters, release of once frozen methane into the atmosphere, landslides, and collapse of the ground itself. The global warming-triggered increase in violent rain events is causing an increase in river flooding, which is further releasing heavy metals embedded in river banks.

HOW WARMING GENERATES SULFURIC ACID

Once permafrost begins to thaw, oxygen seeps into the groundwater, which often changes direction of flow.  Once dormant bacteria become active, oxidizing the sulfide minerals. This process breaks them down into dissolved iron and sulfate, which in turn produces sulfuric acid. The acidified water takes on the color of rust.

Hidden Consequences

Methane released from permafrost thaw

Scary Methane feedback cycle as permafrost releases frozen greenhouse gases.

Methane (CH4) is CO2’s meaner older brother, far more destructive but with a shorter attention span. And Methane is indeed a more powerful greenhouse gas (GHG) than carbon dioxide, rated anywhere from 20 to 30 times more potent. Along with Nitrous Oxide and a few others, GHGs trap heat in the atmosphere.

There is a lot of CH4 trapped beneath the surface of the planet, particularly under the permafrost in Siberia, Alaska and other Arctic regions. As the permafrost thaws, the gases trapped below it spew into the atmosphere, creating a fascinating climate feedback cycle with results that are observable in something close to real time.

Feedback cycles

Megaslump grows in Siberia

Megaslump craters transform Arctic terrain as permafrost thaws

Megaslumps blasting out all over: These wild formations (also known as thaw slumps) are not new, but suddenly they are growing and multiplying. Megaslumps are craters formed by methane gases escaping as the permafrost that once capped it disintegrates. We now see footage of grassland wobbling as the substrata terrain becomes wobbly. When the pressure grows to great, there is a blowout. The resulting thermokarst landscape is expanding.

While megaslumps are not new in places like Siberia, the number has been increasing. Megaslumps include land formations such as the ever expanding Hell’s Gate crater in Siberia and thermotarga landscapes.

Infrastructure collapses as permafrost melts

Northern infrastructure collapsing as the ground shifts beneath it

In Alaska, Siberia and northern Canada, buildings, highways and pipelines are falling down. Humans constructed these artifacts under the assumption that the land would stay solid, but it is NOT staying solid.

As much as half of Arctic infrastructure is at high risk of damage, with estimates of tens of billions of dollars for repairs and replacement.  This estimate does not include the cost of re-locating potentially millions of residents as the area becomes untenable.

Remember when we thought Google was benign?

So much for “Net Zero” commitment.

The search engine and online advertising and AI behemoth with the adorable name is moving ahead to power at least one new AI data center with a 933 MW natural gas plant. This represents a step away from the company’s one time announcement that it would achieve 24/7 carbon free energy,. Of course, there is a difference between announcements and reality. Over the years, Google has managed to seem less evil than many of its tech monster brethren, but that is more or less an illusion. The company has the wherewithal to deploy renewal energy for this and other energy sucking projects, but has chosen not to. The power plant in Texas is the third known gas facility that Google has become involved in over the past few months.

According to the Guardian news platform, the Texas power plant would emit 4.5m tons of carbon dioxide per year, more than that of San Francisco

The new natural gas / methane plant is under construction by Crusoe Energy at Google’s Goodnight Campus in Texas. 

Gaslighting at its best: Why not just call it Methane? 

Natural gas sounds pretty organic man, but it’s 95% methane, along with smaller molecules of ethane, propane and butane. Natural gas is promoted as not as bad as coal as an energy source, but it is composed primarily of CH4. The increase of methane in the atmosphere over the past ten years has been stunning, with surprising consequences in the Arctic. Methane is about 80 times more powerful than CO2 as a greenhouse gas.

Will A Crash In Coastal Tourism Make Humans Pay Attention?

Alarming ocean temperatures, climate driven changes in current patterns and a surge in agricultural nutrients are a perfect environment for these nasty organisms

Global warming is playing a major role in the rapid rise of toxic algae blooms across the world’s lakes, rivers, and oceans. As average global temperatures increase, water bodies warm as well—and warmer water creates ideal conditions for algae to grow faster and more aggressively. Many harmful algal species, particularly cyanobacteria (often called blue-green algae), thrive in higher temperatures. This means that even small increases in heat can significantly accelerate their reproduction, turning what might have been minor seasonal infestation into large, persistent, and toxic outbreaks.

In addition to warming, climate change is intensifying weather patterns in ways that further fuel these blooms. Heavier rainfall and more frequent storms wash excess nutrients—especially nitrogen and phosphorus from fertilizers—into waterways. These nutrients act like fuel for algae, allowing them to multiply rapidly. At the same time, droughts and reduced water flow can stagnate bodies of water, creating calm, slow-moving conditions that are perfect for the toxic animals to thrive  and spread. This combination of nutrient pollution and climate-driven environmental changes creates a feedback loop that increasingly favors harmful algae over other aquatic life.

Toxic Algae Blooms are Visible From Space and already impacting coastal tourism around the world

Blooms? How language is deployed

In most descriptions of the growing algae crisis, the spread of the organisms is described as a “bloom.” You know: like flowers. Similar to methane rebranded as natural gas or toxic fracking waste renamed “brine.”

Who do you think will win the NCAA (March Madness) basketball tournament?

My long held belief is that most of the species will remain uninterested in global warming emergency until their lives are affected. How do you compete with March Madness or the new baseball season?  Interest will begin peaking when the consumerati find their candy bars disappearing, lattes $20 a cup and shellfish no longer on the menu.

 

 

Health, Ecosystems and Economies

Many harmful algae produce toxins that can contaminate drinking water, kill fish and wildlife, and cause illness in humans, ranging from skin irritation to serious liver and neurological damage. Coastal economies and fishing industries also suffer when blooms lead to dead zones—areas with little to no oxygen—making it impossible for marine life to survive. As global temperatures continue to rise, scientists expect these blooms to become more frequent, longer-lasting, and more widespread, making them a growing environmental and public health crisis.

 

 

Vanishing glaciers on Germany’s highest mountain resulted in demolition of another Alpine ski lift.

Europe is losing hundreds more to global warming.

German ski resort demolished

“The glaciers in Bavaria will inevitably melt away, as they can no longer survive in the face of climate change,“.

A ski slope on Zugspitze mountain has been dismantled because the glacier beneath it melted away

Global warming is reshaping the Alps in a number of ways as the region heats about four times faster than the rest of the planet. Among the most economically painful is the closing of ski runs and entire results. The latest high profile loss is a ski slope down the Schneeferner glacier on the Zugspitze mountain, which has been demolished as the glacier beneath it disappeared for good. The life has been in operation for 50 years. The peak of Zugspitze is 9,700 ft. high, located in the Wetterstein massif along Germany’s border with Austria.

HUNDREDS OF EUROPEAN RESORTS CLOSING OR THREATENED BY CLIMATE CHANGE

Across Europe and especially in France, warming temperatures are forcing ski resorts to close permanently or abandon traditional operations, with 186 resorts in France closing the in the past several years. Up to 98% of European resorts face severe snow shortages. While many are filling in with artificial snow, there is a limit to that process, which also uses huge amounts of energy.

Glacial Lake Outburst Floods (GLOF) are not new, but the incidents of these startling events are ramping up as mountain glaciers melt. Several recent incidents have had catastrophic results in Alpine regions around the world.

As glaciers melt at a frenetic pace, new lakes back up behind newly ice dams in the Andes, Alps and Himalayas. When these dams break, massive torrents rush downstream, often in a cataclysmic flood. These floods have become more common as global warming causes rapid melting of glaciers around the world.

Arizona breaks all time March heat record for US

Martinez Lake, Arizona reached 110°F degrees  on Thursday, breaking a record for the highest March temperature recorded in the United States. The record-setting temperature was recorded as a winter heat wave scorched the Southwest, according to the National Weather Service. 

The previous record of 108 degrees had been set in Rio Grande City, Texas, in 1954. North Shore, California matched the temperature. 

Globally, heat records are also falling in South America and the Middle East.

New Arctic Sea Ice “Low Maximum Extent” ushers in Spring

Yet another new record daily low was set for Arctic sea-ice extent, over 50,000 km² below the previous record daily low, previously set on March 17, 2017.

The low maximum is not a contradiction. It means: 

  • In winter, the Arctic ice pack expands its area
  • Satellites measure the maximum extent each season, usually in March
  • The reference to low maximum extent means total area continues to shrink year to year.

The 2025 Arctic daily sea ice maximum extent reached a record low of 5.53 million square miles) on March 22, 2025 the lowest in 47 years of satellite records. 2026 is about same, or slightly less.

Extreme storm delivers 135 MPH winds, 62 in. rainfall and major devastation in Hawaii 

Hawaiians are just beginning to recover from a historic storm in early March that shattered decades-old rainfall records and left a trail of destruction from Hanalei to Kihei to Hilo.

From 135 mph wind gusts on Hawaii Island to 62 inches of rainfall on Maui, a recent Kona low system brought weather conditions usually reserved for major hurricanes to the state. 

Alongside immense flooding, the storm brought destructive winds. The Hawaii Mesonet station on Hawaii Island recorded a maximum wind gust of 135.4 mph. Winds were briefly sustained at speeds equivalent to a Category 2 hurricane, averaging 105 MPH over a 15-minute period.

Maui was hit the hardest, with peak rainfall totals reaching 62 inches in localized regions. 

A similar Kona Low system is heading towards Hawaii on March 19, bringing additional rain and gusty winds to the island.

Global deforestation increases

Deforestation continues to increase globally, driven by agriculture and illegal logging

According to the FAO, from 2015 to 2025, the planet lost an average of 10.9 million hectares of forest per year. The highest rates of deforestation are  in Africa and South America, where forests are burned out to be replaced by crops and pastures for cattle..

The Amazon in particular experienced a significant surge in losses, with a 110% increase in some areas between 2023 and 2024. Deforestation also spiked in the Brazilian Cerrado, Bolivia, and Indonesia.

Many nations have made pledges to help slow the destruction, but few have done anything but talk.

Kenya flood death toll rises to 71 as forecasters warn of renewed heavy rainfall

At least 71 people have died in flood-related incidents across Kenya since March 6, 2026, with Nairobi the hardest-hit area, as the Kenya Meteorological Department issued a Heavy Rainfall Advisory on March 18, warning that rainfall will intensify again across most parts of the country through March 24.

Flash floods had begun affecting the region since March 6–7, when overnight rainfall caused the Nairobi River to burst its banks.

Currently, a total of 36 fatalities have been confirmed in Nairobi, 19 in the Eastern Province, 8 in the Rift Valley, 4 in Nyanza, 3 in Coast, and 1 in the Central Province. Most of the fatalities were caused by the overflow of the Nairobi and Ngong Rivers.

At least 2 622 people have been displaced and sheltered, and several homes and roads have been destroyed; damage to power lines and water infrastructure has also been reported.

More Intense rain events hit southern Italy 

Severe weather triggered flooding and landslides across parts of southern Italy, with the worst impacts reported in Calabria, particularly in the province of Cosenza. Intense rainfall exceeding 200 mm in just 24–36 hours overwhelmed rivers including the Trionto River and Fiumarella River, leading to rapid flooding across urban areas. Towns such as Crosia, Corigliano-Rossano, and nearby coastal communities experienced landslides, submerged roads, and evacuations as unstable hillsides collapsed under saturated conditions. Emergency services responded to over 100 incidents, while dozens of residents were evacuated from high-risk zones. Authorities warn that ongoing soil instability and elevated river levels may continue to pose risks, even after rainfall decreases, highlighting the growing impact of extreme weather across southern Italy..

Flash floods in Tripoli continue pattern of lethal weather events

Heavy rain and strong winds caused flooding across the Libyan capital of Tripoli. The National Meteorological Centre warned residents in western regions, particularly in Tripoli and surrounding areas, to remain indoors overnight into Tuesday morning as severe weather continues. Emergency services said they had received distress calls from motorists stranded on several roads, including parts of the capital’s ring roads, after rising rainwater levels left vehicles trapped.

A teenager was electrocuted and killed by a downed power line while attempting to rescue people trapped in floodwaters in Tripoli’s Tajoura district overnight.

Upwards of 10,000 people were killed by floods in Sept. 2023.

Jellyfish bloom shuts down 2 nuclear plants in France

Warming oceans driving jellyfish into new habitats

It’s not science fiction and it’s not an isolated incident.

In August and September 2025, massive swarms of jellyfish caused significant disruptions at two of France’s largest nuclear power plants, Gravelines and Paluel, by clogging their cooling water intake systems.

A “massive and unpredictable” swarm of jellyfish entered the Gavelines water pumping station filters, leading to the automatic shutdown of four of the plant’s six reactors. With the other two units already down for maintenance, the entire site was temporarily nonoperational.

Less than a month later, jellyfish clogged filters at the Paluel plant in Normandy forcing shutdown of one reactor and reducing the output of another by a total of 2.4 gigawatts.

CLARIFICATION: You may encounter overwrought descriptions of these events using the term “angry jellyfish,” but these primitive marine lifeforms have neither brains, nor to the best of our knowledge, emotions. 

Global Warming one of several human driven causes (But the j-fist aren’t actually angry)

As with most climate driven environmental tragedies, the causes of global jellyfish blooms are multiple and interlocking. The one common factor is humans.

  • Climate Change: Warmer ocean temperatures speed up jellyfish reproduction and increase plankton populations, their primary food source.
  • Overfishing: The removal of natural predators like tuna and sea turtles allows jellyfish populations to grow unchecked.
  • Invasive Species: Cargo ships can transport invasive jellyfish species, such as the 
    Asian Moon jellyfish , into new environments via ballast tanks.

Jellyfish invasions increasingly shut down nuclear plants

  • Scotland: The  Torness nuclear plant 2011 | 2021.
  • Philippines: 1999 Massive blackout 
  • Other Locations: Shutdowns or disruptions have been reported at coastal plants in Japan, Israel, and the United States..
