War Zones In Nigeria Leave Disabled People Behind; In the US, We’re Doing It Too

The system that has failed Disabled people during Nigeria’s security crisis is the same system that fails us here in not just natural disasters like hurricanes or wildfires, but active shooter situations, and immigration detention as well.

Hurricane season is upon us, and for many Disabled people across the US, it means a renewed sense of insecurity and uncertainty around their well-being. So often, Disabled folks are too often left behind in emergency preparedness and response efforts, and are ultimately treated as afterthoughts. With the 21st anniversary of Hurricane Katrina approaching and a continued climate crisis with no end in sight, this glaring oversight is ever present in the minds of Disabled people nationwide.

This isn’t an issue that’s unique to the US, however. It’s something that Disabled communities face on a global scale, and it’s time we took a hard look at what countries across the world can do to center Disabled people in ensuring the safety and security of their citizens.

Take Nigeria, for example. A new investigation from Deaf Nigerian filmmaker and journalist Alexander Ogheneruemu, “Forgotten People,” tells, in part, the story of Ayoade Beyioku-Alase, a Deaf man who was nearly killed as a child in Kano because the violence closing in on his house came with no siren, no interpreter, no warning he could access. “A Deaf person can walk right into the middle of danger,” he says in the piece.

It’s easy for those of us in the US to read a story like this and feel far away from it. It’s easy to think, ,“This isn’t us.” The truth is that, whether we want to accept it or not, it is us. It just looks a little different.

Disabled people in the United States are two to four times more likely to die or be critically injured in a disaster than nondisabled people.

As a Disabled person who has worked in this space for many years, I can tell you that the system that has failed Disabled people during Nigeria’s security crisis is the same system that fails us here in not just natural disasters like hurricanes or wildfires, but active shooter situations, and immigration detention as well. The threat might be different, but we have more in common with these failings than you’d be led to believe.

The alarm itself is the most direct parallel. Federal guidance from the Department of Justice acknowledges that most emergency warning systems in this country were built for people who can hear and see. Sirens, radio, television, flashing lights are all assumed to be visible to everyone. Tornado sirens across the Midwest and South are audio only, offering nothing to a Deaf person indoors when weather becomes a threat. The National Association of the Deaf has told emergency management agencies for years that mass notification systems don’t reach people who rely on video instead of standard calls. This is a serious and blatant example of ableism, where Disabled people are treated as an afterthought in emergency planning.

In Ogheneruemu’s “Forgotten People,” produced by the Disability Justice Project, the journalist says that 4,654 lives were lost in Nigeria’s insecurity crisis last year. Our own numbers are just as alarming. Research compiled by the Center for American Progress and the Partnership for Inclusive Disaster Strategies puts it bluntly: Disabled people in the United States are two to four times more likely to die or be critically injured in a disaster than nondisabled people.

During Hurricane Katrina, people over 60 years old, who included many Disabled folks, made up 73% of storm-related deaths in Louisiana. According to the National Council on Disability, 68 of those victims died in nursing homes, some abandoned by staff who left rather than arrange evacuation. Twenty years later, not much has changed. When the Eaton Fire tore through Los Angeles in January of 2025, at least 3 of the 27 people killed were Disabled, and NBC News reported that Disabled people displaced by disaster are almost twice as likely not to return home.

Then there’s our own man-made violence. Nigeria’s crisis comes from armed conflict, and ours also often comes from gun violence. More than 100 US school shootings have happened since Sandy Hook in 2012, and the response drilled into an entire generation of children is to run and hide. Inherently, this completely excludes Disabled kids. The Washington Post and The Mighty have both documented children left alone in hallways, forgotten in therapy rooms, and locked out of safe zones during lockdowns because there wasn’t a plan that accounted for them. New Jersey only recently passed legislation forcing districts to build disability-specific evacuation plans after families spoke out. The message we’re sending to Disabled kids here is that they’re on their own.

The Disability Justice Project’s own reporting has already shown us what this looks like at our own border: a Deaf asylum-seeker was held for five months in Immigration and Customs Enforcement detention without a sign language interpreter, ultimately unable to explain to anyone why he was afraid to go home. If disability access can vanish inside a US federal detention facility, we have no standing to act shocked that it vanishes during a flood or a fire.

This isn’t the kind of thing that’s unknowable, either. The data is out there, and the stories are plentiful. It’s simply not prioritized by those in power, and more often than not it’s unfunded. Disability still makes up just 2% of philanthropy, despite Disabled people comprising about 25% of the US population. Every dollar that goes toward disaster response, school safety, or immigration oversight without disability at the center is putting more Disabled folks in harm’s way. And even if that isn’t you, it could be your mother, father, child, friend, or neighbor. That’s why funding disability is more important than ever. We don’t need another report to tell donors and policymakers that Disabled people die preventable deaths in emergencies.

Instead, we need them to stop treating that fact as new information every single time it happens. Funders, just like lawmakers and others in positions of power, need to wake up and see for themselves just what the disability community is up against.

If we can learn one thing from the security crisis in Nigeria, it’s that Disabled people deserve the same protections and safeguards that nondisabled people have in dangerous and precarious situations. It’s already too late, but in the US, in Nigeria, and in countless other countries, there’s still time to save many more Disabled lives.

Horror as 'super El Niño' threatens disaster not seen in 1,000 years

Weather scientists watching the Pacific Ocean are witnessing something they've never seen — a "super El Niño" now forecast to blow past every record in the modern era, with one meteorologist claiming it could be the most extreme climate event in a thousand years.

The alarm intensified Wednesday when meteorologist Ben Noll flagged a new outlook from the European weather model, the ECMWF, projecting the event will peak near +4.0 degrees Celsius above average in the tropical Pacific this December. The number, he said, would obliterate the previous record. For context, the strongest El Niños ever instrumentally recorded, in 1997-98 and 2015-16, topped out around +2.6 degrees Celsius.

The forecasts have been climbing for months. NOAA declared an El Niño Advisory in June, and the World Meteorological Organization now puts the odds above 90%. Multiple models agree the event is barreling toward +3 degrees Celsius or higher, which several forecasters warned would make it the strongest on record.

Meteorologist Jeff Berardelli captured the disbelief among scientists. "If you had asked us if something like this was possible a year ago, it would have probably been a definitive no," he wrote, noting the event is already running more than a degree — and three months — ahead of the monster 1997 El Niño. "We are headed into outer space."

The most dramatic claim came from meteorologist Ryan Maue, who wrote that the "super El Niño" will "perhaps be the strongest in 500 to 1000 years" and "could legitimately be the most extreme global weather or climate event experienced by humanity since the invention of the printing press."

The consequences, if the forecasts verify, would ripple worldwide.

Noll said the new outlook painted a "stormy winter picture" for the U.S. East and West coasts and Europe, driven by a turbocharged subtropical jet stream. Maue projected deluges from "atmospheric rivers" in California, a warm Canadian winter, and a wet, colder-than-normal, ice-storm-prone stretch from Texas across the Southeast and Florida. El Niño also tends to suppress Atlantic hurricanes while, as Berardelli noted, supercharging heat waves, wildfires and Pacific typhoons.

The World Meteorological Organization has already flagged heightened risks of drought, flooding and heat, and the World Economic Forum recently called the coming event "more than a climate event," warning it could hit global food and energy systems at once. Past super El Niños have been linked to trillions of dollars in global economic losses.


Nearly 50 Million More People to Face ‘Massive Threat’ of Acute Hunger Due to El Niño, UN Warns

Countries in Central America and southern Africa are expected to be hardest hit by El Niño this year, according to the United Nations World Food Program.

The United Nations World Food Program on Wednesday warned that close to 50 million more people across the world are facing the prospect of acute hunger due to the El Niño climate pattern that has emerged this summer.

By the end of the year, the WFP projects that 49 million more people could be unable to meet their daily food needs thanks to El Niño, which features warmer than average temperatures in the Pacific Ocean and can cause an increase in extreme weather.

Countries in Central America and southern Africa are expected to be hardest hit by El Niño this year. According to WFP’s analysis, southern African nations are “particularly exposed because many households depend on rain-fed subsistence agriculture,” while nations in Latin America and the Caribbean “could see one of the sharpest rises in food insecurity, with more than 16 million people affected.”

“El Niño is a massive threat to the food security of millions who are already vulnerable,” said Carl Skau, acting executive director of the WFP. “The sooner we help families to prepare for these climate shocks, the greater our ability to save lives and protect livelihoods.”

WFP said it’s boosting its hunger prevention efforts in eight countries that are particularly at risk, noting that it has already “triggered anticipatory action plans in South Sudan, Chad, Mauritania, Uganda, Guatemala, and El Salvador, providing more than $14 million in lifesaving responses to support half a million people.”

Celeste Saulo, secretary-general of the World Meteorological Organization (WMO), warned in June that El Niño “will exacerbate drought and heavy rainfall and increase the risk of heatwaves both on land and in the ocean.”

While El Niño is a recurring phenomenon, a Wednesday report in The Guardian noted that “its impacts and strength are being strongly affected by the climate crisis,” with meteorological experts saying it could lead to the hottest year on record in 2027.

Monster El Niño coming. Will “The Child” Finally Wake Us Up to the Climate Emergency?



 August 4, 2026

The Pacific is now brewing up an El Niño that could well be the most powerful in recorded history by a wide margin. It will ramify to droughts and fires, storms and floods across the world. Will it be strong enough to wake the world to the need for emergency level climate action?

Is humanity’s “invisible hand” reappearing?

In 1998 a monster El Niño was roiling the Pacific, skewing weather patterns all over the planet. The world had just experienced a string of record hot months. Then Vice President Al Gore was preparing for a press conference on the climate turbulence. An aide called Sierra Magazine Editor Paul Rauber to ask if he had any leads on the connection between intensifying El Niños and climate change.

“We have something in our latest issue,” Rauber replied.

“It’s on the top of my pile,” the aide chimed back.

The article was “The Invisible Hand,” subtitled, “As human activity warms the earth, El Niño grows more violent. Are we doing this to ourselves?” I was the author. In 1997, seeing a second super El Niño coming on after only 14 years, I dug into the question. I had been bringing climate change into my writing for nearly a decade, but this was my first deep dive into climate science.

I interviewed many climate scientists, including some of the absolute stars. Charles Keeling, who in 1958 led creation of the Mauna Loa monitoring station that is still the world’s leading CO2 measurement site (which the Trump Administration wants to shut down, for obvious reasons). Wallace Broecker, who identified the global interconnection of ocean currents and their capacity to cause abrupt climate change. In our interview, Broecker repeated the line he must have included in some version in every interview. “The Earth’s climate is like an angry beast, and we’re poking it with sticks.” Kevin Trenberth, chief scientist at the National Center for Atmospheric Research (another institution being dismembered under Trump). Trenberth had found the repeat of two super El Niños so close together probable to happen only once every 2000 years.

While the question of whether increasing global heating was driving El Niños was unsettled, the scientists repeatedly called out a key issue. What happens when normal climate variability such as El Niño piles on top of global heating? How will it impact the chaos an El Niño normally causes – droughts, wildfires, drenching storms, coral bleaching, agricultural collapse? It looks like we’re going to get some fresh answers to the question.

The monster El Niño now brewing in the Pacific seems on course to be the most intense on record, and by a long shot. Hotter by far than recent super El Niños in 1982-83, 1997-98 and 2015-16. Zeke Hausfather, a climate scientist with Berkeley Earth, puts it in context. His comments are all the more striking because he has a reputation for being reserved in his conclusions, as he confirms in the first line of a recent post at his Climate Brink site.

“I’m generally pretty measured in how I discuss climate data. There has been only one time in recent years when I was truly shocked: when global temperatures came in for September 2023 at a full 0.5C warmer than any prior September on record. Once until today, that is. With the July runs now in from 667 ensemble members across 14 different seasonal forecast models, it looks like this year’s El Niño is not only very likely to be the strongest event since reliable records began – it may end up the strongest by a truly mind-blowing margin.

“The multi-model median for the event’s peak . . . currently stands at 3.6C, roughly 0.8C hotter than the prior record of 2.75C set in 2015-16. For context, the gap between the strongest and the fifth strongest El Niño of the past 150 years is only about 0.5C. The models are forecasting something outside the envelope of anything we have ever observed.”

This graphic depicts just how far the current El Niño exceeds past El Niños,, including super El Ninos of the past five decades. Used with permission from Zeke Hausfather.

Hausfather reports other stunning facts. Ocean temperatures in the mid-Pacific are rising the fastest on record, and out of a cool La Niña condition. As of mid-July they were hotter than any time in a 45-year record of satellite measurements. “No El Niño has run this hot by July,” he says. 2026 was already on track to rank as one of the hottest years on record. These conditions have ramped up the probability 2026 will beat out 2024 as the hottest year from 13% at the beginning of July to 28% by mid-month. Because of El Niño, 2027 will almost certainly take the record with projections ranging around 1.7C, yet another year exceeding the Paris Climate Accords target of 1.5C maximum heating.

The planet is already in its 11th year of record or near record global temperatures. This has supercharged the atmosphere with water vapor that feeds inundations and flooding. Every degree Celsius translates into 7% more moisture in the atmosphere. This El Niño explodes on a world already roiled by global heating. It can only intensify the situation.

Is climate heating intensifying El Niño?

In order to parse out the El Niño-climate change connection, it is crucial to understand exactly what an El Niño is. Oceans absorb most solar heat accumulated by the planet. The Pacific is the largest ocean, covering nearly half the Earth’s surface. Its greatest solar collector is the tropical western Pacific. An El Niño is its heat discharge mechanism. It is the world’s largest interannual climate variability, and overall the biggest regular event on the planet other than the change of the 4 seasons. By a complex series of interactions, increasing heat weakens trade winds holding the warm pool to the west. It then migrates east in the classic tongue pattern seen in depictions of a full-blown El Niño. It gained its name, Spanish for “The Child,” because it has tended to have its greatest effects around Christmas. Fisherman in Peru felt it because the warm surface stops an upwelling of cool water that feeds fish populations, collapsing catches.

As the warm tongue reaches across the Pacific, its effects radiate throughout the world’s ocean and atmosphere system. It twists global wind currents such as the jet stream in ways that bring more rains to some regions while drying out others. El Niño is like a cue ball smashing into a rack and sending balls all over the table. The word used to describe this is teleconnections. Typical impacts are monsoon failure in India, drought and fires in Australia, Indonesia and the Amazon, and flooding along South America’s Pacific coast and in East Africa. The record heat currently driving a devastating fire season in France and Spain is in line with past super El Niños, as are heat domes in North America.

So in a heating world, shouldn’t the planet’s greatest collector of solar heat be discharging it more often and with greater intensity in the form of El Niños? That is the logic I pursued in my 1998 piece. But the climate system is incredibly complex, and temperature records only go back a limited time. Scientists are a cautious lot. They are more inclined to project that increasing heat will affect El Niños in the future, because of the basic logic. But they are still going back and forth on current impacts. So science is only slowly moving to the conclusion that El Niños are being made more frequent and powerful by global heating.

“It’s highly contested, because it’s such an important question to get right,” Brown University climate scientist Kim Cobb told the New York Times in a recent article, “Is Climate Change Supercharging El Niño? A Debate Rages.”

“Of 16 scientists who spoke with The Times, eight said they see compelling evidence that climate change is likely increasing the intensity of El Niño events. Among them is Michael McPhaden, a senior scientist at NOAA, who cautioned that the science is ‘very uncertain,’ but said the development of another strong El Niño this year would be ‘pretty remarkable.’ If the current El Niño reaches the proportions that many forecast, it would mean three of the six strongest events since 1950 have come in the last 11 years.”

Again, those are the 11 hottest years ever recorded on the planet.

One of the most definitive statements on the El Niño-climate change connection has been made by Wenju Cai, a climate scientist at Ocean University of China. Using advanced computer modeling to build a record of past El Niños, Cai and his team drew several critical conclusions. They compared the period from 1901-60 to 1960-2020. Three-quarters of model runs found events in the later period around 10% stronger on average. They compared the runs to a world in which greenhouse gases were at levels before the industrial revolution. The odds that these increases would have happened in such a world are 2.5-10%.

“It’s almost impossible for this to happen without climate change,” Cai told the New York Times.

McPhaden, a participant in the study, and chief scientist at NOAA Pacific Marine Environmental Laboratory in Seattle, a center of El Niño research, wrote,” One manifestation of this amplified cycle is that strong El Niño and La Niña events are becoming stronger and more frequent, just as we’ve observed in the more recent historical record. The big events pack the most punch, so even though 10% doesn’t sound like much, it juices up the strongest and most societally relevant year-to-year climate fluctuation on the planet . . . this amplified cycle translates into more extreme and frequent ENSO-linked droughts, floods, heat waves, wildfires and severe storms . . . “

When will we wake up?

What are broader implications of all this? It is beyond doubt that the heat release mechanism of El Niño will ramp up already devastating climate extremes breaking out all over the planet. If El Niños and their companion La Niñas are themselves amped up by global heating, it creates a feedback loop that makes those extremes all the more destructive.

Yet, as climate disruption reaches new levels, much of the world seems to be turning away from climate action. In the U.S., Trump is tearing apart climate science institutions and undermining clean energy growth, while Republicans continue to sing in the denier choir. Meanwhile, Democrats are climate hushing in the name of affordability, ironic in the face of how global heating is driving up grocery bills, home insurance and a plethora of other costs. In Europe, which has been a climate leader, nations under economic pressure are stepping back from net zero commitments. Global climate pollution continues to rise, though in one bright spot, China’s emissions appear to have peaked.

At one level, this introduces a sense of global cognitive dissonance. The intensification of climate impacts across the world should lead to a crisis response. We should be recognizing this is a global emergency. Instead it’s going the opposite direction. But there’s a schizoid logic in all this, a classic double bind. There is widespread knowledge that we face a critical situation. But we cannot collectively come to terms with what this means, the absolutely massive transformation of economic and energy systems that will be required. So we retreat into denial, soft or hard, that lets us go on with our day to day routines.

The question is what will wake us up? What will cause us to finally confront the necessity, when people push our political leaders to act while making the changes in our own lives that we must? We can hope what will take place in coming months will be so alarming it will stir the necessary response. But I’ve been at this long enough to have seen many events I thought would do this. Katrina’s destruction of New Orleans. Superstorm Sandy’s ravaging of New York City. So much as I hate to say it, I’m not optimistic. But we who are aware need to use this opening anyway. We need to call out the emergency situation facing our world, and especially media that do not make the connection between disasters and climate.

In any event, we are already in the age of climate extremes. They will only intensify from here on until we zero out climate pollution. So while we move toward zero, we also need to place a top priority on climate adaptation at every level, from local and state/provincial to national and international. We need to prepare our communities for the storms, floods, heat, drought and fires to come. Meanwhile, we need to continue to do all we can to reduce climate pollution, and bust business-as-usual assumptions that say we can stay on anything like the current course. If we continue, adaptation will become ever more difficult and eventually impossible. In the process of adapting, we must focus dual opportunities to adapt and reduce. For example, wetlands can buffer against floods and sea level rise while absorbing carbon. Sustainable agricultural practices can reduce farm pollution while absorbing carbon in soils. Better insulated buildings can protect against temperature extremes while cutting energy use.

Dealing with climate also offers chances to build a more just society. Climate disruption stresses all the fault lines in society such as widespread food insecurity. The immediate impact of this El Niño will worsen this as crops fail and prices increase. Over coming decades, food insecurity is likely to have the broadest climate impact on human populations. Too many people lack enough food already. We should address this anyway with comprehensive efforts to make sure people get enough, but a heating climate will drive us in this direction. It will take a strong society to cope with what’s coming.

It has been my hope that the multiple crises barreling down on the human race will make us a wiser species chastened by the consequences of our collective hubris. I have to say when I read news of what’s going on around the planet, I often feel a clenching in my gut. It sickens me we have gone so far while letting powerful interests throw away our collective future. At some point, we have to wake up. Let us do all we can to make this “mind-blowing” El Niño that point. May “The Child” cause us to think about our own, and the world we are leaving them.

A native California wildflower isn’t keeping up with climate change



Mountain jewelflower may hold lessons for helping other species

The mountain jewelflower inhabits a wide swath of California and Oregon, from summer-scorched foothills to high mountains where snow falls during winter. But it is already suffering from climate change, with plants in the mountains struggling to survive both summers and winters, according to a study from the University of California, Davis.

“Evolutionarily, it isn’t keeping up with changes in the environment,” said lead author Brandie Quarles-Chidyagwai, a UC Davis postdoctoral scholar in the Department of Plant Biology. 

Different populations of this species evolved over millennia to fit California’s diverse environments. With climate change, those adaptations may no longer match local conditions, potentially threatening the mountain jewelflower (Streptanthus tortuosus) — especially in the high mountains.  

However, the study, published in the Journal of Ecology, also provides hope. It found that plants from lower elevations may have traits that match new mountain conditions. 

“It suggests potential conservation strategies that might help these plants,” Quarles-Chidyagwai said. 

A strategy called assisted gene flow could reshuffle the plant’s gene variants into new combinations that better match the new climates. The same strategy could also help many other plant species.

Changing climates in the western U.S.

As temperatures warm, California has seen frequent droughts, with reduced snowpack and earlier snowmelt in the Sierra Nevada. Conditions at high elevations have become more like what low elevations experienced in the past. This has shifted the timing of growing seasons and altered the conditions that plants experience during them.

The mountain jewelflower is already falling behind these changes, according to results previously published research by UC Davis Professors Jenny Gremer and Julin Maloof. Their experiments on low-elevation plants suggested that if the growing seasons shift, the plants’ seeds are less likely to sprout — and the plants that do emerge produce fewer seeds. 

“We know that shifting seasons are already having negative effects on low-elevation populations,” Gremer said. “We also wanted find out how other populations are doing.”

Quarles-Chidyagwai worked with Gremer and Maloof to examine how climate change is affecting one especially vulnerable part of the species: mountain jeweflowers adapted to cold, high-elevation landscapes.

At a site high in the Sierra, they planted seedlings from various regions of California — including both high-elevation areas and lower, warmer, drier areas. If the high-elevation plants fared better than the others, it would suggest that even after a century of climate change, they were still well-adapted to their home range.

But the results showed something very different.

During the first summer, the high-elevation plants survived and produced seeds at lower rates than the lowland plants did. Surprisingly, when Quarles-Chidyagwai returned the following June, she found that the high-elevation plants had once again fared worse, surviving the winter at lower rates than the plants from lower, warmer areas.

This suggested that these high-elevation plants were no longer well-adapted to their environment, suffering not only through a hot, dry summer, but also through a winter when the snow was unusually thin, providing the plants with less protection.

That bodes poorly for the future, said Quarles-Chidyagwai: “We’re going to see more winters with less consistent snowpack.”

Mixing genes to meet the moment

The experiment also yielded a hopeful result.

Despite suffering through the first summer and winter, high-elevation plants survived their second growing season at higher rates than the other plants, allowing them to produce more seeds across their lifetimes.

This suggested that despite climate warming, the high-elevation plants are still well-adapted to at least some aspects of their mountain environment. More importantly, it indicated that the species possesses a set of gene variants that may help it survive newly emerging climates. Those useful gene variants just happen to be scattered across different populations of the plant inhabiting different parts of California.

Quarles-Chidyagwai, Maloof and Gremer are now doing assisted gene flow experiments to combine those gene variants into a single population of plants. 

By interbreeding mountain jewelflowers from high and low elevations, “we can hopefully get the ideal combination of genes and create an ideal plant” for these new climates, Quarles-Chidyagwai said.

Insights gleaned from the mountain jewelflower suggest that assisted gene flow might also help other plant species adapt to changing climates.

“When you have these broadly distributed species, that can be useful for conservation,” Quarles-Chidyagwai said.

This research is funded by the National Science Foundation and the National Institute of Food and Agriculture. It used advanced scientific facilities at UC Davis, including the Controlled Environment Facility and research greenhouses.

Additional coauthors include Sarah Ashlock and Johanna Schmitt from UC Davis.

Transplanting jewelflower field work 

Researchers transplant mountain jewelflower seedlings, derived from 23 different populations across California, into a single site in the Sierras. They are assessing whether the flowers are still well-adapted to their home range, as well as how plants from other areas may help them cope with the changing climate.
