Zombie Viruses of the Permafrost

Jan 24, 2024

By KIM BELLARD

We’ve had some cold weather here lately, as has much of the nation. Not necessarily record-breaking, but uncomfortable for millions of people. It’s the kind of weather that causes climate change skeptics to sneer “where’s the global warming now?” This despite 2023 being the warmest year on record — “by far” — and the fact that the ten warmest years since 1850 have all been in the last decade, according to NOAA.

One of the parts of the globe warming the fastest is the Arctic, which is warming four times as fast as the rest of the planet. That sounds like good news if you run a shipping company looking for shorter routes (or to avoid the troubled Red Sea area), but may be bad news for everyone else. If you don’t know why, I have two words for you: zombie viruses.

Most people are at least vaguely aware of permafrost, which covers vast portions of Siberia, Alaska, and Canada. Historically, it’s been literally frozen, not just seasonally but for years, decades, centuries, millennia, or even longer. Well, it’s starting to thaw.

Now, maybe its kind of cool that we’re finding bodies of extinct species like the woolly mammoth (which some geniuses want to revive). But also buried in the permafrost are lots of microorganisms, many of which are not, in fact, dead but are in kind of a statis. As geneticist Jean-Michel Claverie of Aix-Marseille University, recently explained to The Observer: “The crucial point about permafrost is that it is cold, dark and lacks oxygen, which is perfect for preserving biological material. You could put a yoghurt in permafrost and it might still be edible 50,000 years later.”

Dr. Claverie and his team first revived such a virus – some 30,000 years old — in 2014 and last year did the same for some that were 48,000 years old. There are believed to be organisms that ae perhaps a million years old, far older than we’ve been around. Scientists prefer to call them Methuselah microbes, although “zombie viruses” is more likely to get people’s attention.

He’s worried about the risks they pose.

Some Like It Hot! A Century-Old Disease on Our Southern Shores

Oct 30, 2023

By MIKE MAGEE

Naomi Orestes PhD, Professor of the History of Science at Harvard, didn’t mince words as she placed our predicament in context when she said, “If you know your Greek tragedies you know power, hubris, and tragedy go hand in hand. If we don’t address the harmful aspects of human activities, most obviously disruptive climate change, we are headed for tragedy.”

At the time, as a member of the Anthropocene Workgroup, she and a group of international climate scientists were focused on defining and measuring nine “planetary boundaries,” environmental indicators of planetary health. At the top of the list was Climate Change because, one way or another, it negatively impacts the other eight measures.

Not the least of these “human perturbations” is the effect of global warming on access to clean, safe water, and the impact of violent weather cycles and rising sea levels on concentrated urban populations along coastal waters.

A less recognized, but historically well documented threat, is exposure to migrating vectors of disease as they contact unprepared human populations beyond their traditional camping grounds. The threat of avian flu among migratory birds has been well covered. Equally, over the past decade, North America has seen a range of novel infections, especially along our southern borders, from dengue, to chikungunya, to Zika.

The southern United States and its coastal populations are firmly in the cross-hairs. Their seas are rising at an alarming rate, and fouling fresh water supply with invasive sea water. Their soaring temperatures are only exceeded by record setting atmospheric river rainfalls and flooding events, and their “extreme poverty throughout Texas and the Gulf Coast states, where inadequate or low-quality housing, absent or broken window screens, and a pervasive dumping of tires in poor neighborhoods,” as reported in this weeks New England Journal of Medicine, assures a reemergence of one of this countries most significant, but now long forgotten killer diseases.

In 1853, the disease killed 11,000 in New Orleans, some 10% of the population. Twenty-five years later, it overwhelmed Mississippi Valley cities killing 20,000. Its latest major foray in the United States was in 1905 with 1000 deaths. Its’ absence over the past century is credited to public health and structural and engineering advances. But that was then, and this is now.

The disease is Yellow Fever, and red lights are blinking in a range of southern coastal cities from Galveston, TX, to Mobile, AL, to New Orleans, LA and Tampa, FL.. Experts say they may soon be in the same boat as Brazil was between 2016 and 2019 when it experienced a threefold increase in the historic prevalence of the disease among its population.

Public Health sleuths have uncovered that the 1878 epidemic in the Mississippi Valley was triggered by an El Nino spike the year prior. The warmer and wetter conditions are believed to have supported a large increase in Aedis aegypti mosquitos, the vector for the Yellow Fever virus.

Are we prepared? Recent experience in fighting Dengue fever in the southern statesis not encouraging, with WHO chief scientist Jeremy Farrar warning that Dengue might soon “take off” absent better mosquito eradication and screening prevention. U.S. Public Health experts say a Dengue foothold is nearly secured and the disease is fast on its way to becoming endemic in southern coastal states.

As for Yellow Fever, there is an effective vaccine, but it is also associated with rare but serious side effects. Antivaccine activism post-Covid would be a significant barrier now say experts. Adding to the challenge, no Yellow Fever vaccine is currently available from the U.S. Strategic National Stockpile. Mosquito surveillance programs are currently marginal, and response capabilities for mass vaccination in affected areas are severely limited.

The Anthropocene Workgroup is fully aware of these human instigated crises. In the prior Holocene Epoch of 11,700, we prided ourselves with being able to co-exist with other lifeforms and in equilibrium with a healthy planet. But beginning in 1950, the new Anthropocene Epoch has aggressively chipped away at planetary health, disrupting stabilizing cycles, and critically raising the temperature and acidity of oceans that cover and buffer 70% of the planet.

The return of Aedes aegypti, and the Yellow Fever virus it carries, is a dramatic harbinger of additional challenges to come if we are unable to limit “human perturbations” of our planetary cycles.

The “Green Pope” Loves Science and Is Cautious of AI

Oct 11, 2023

By MIKE MAGEE

By all accounts, they were mutually supportive. He was three years older and the chief scientific adviser to the world’s most powerful religious leader. The Scientific American called him “the greatest scientist of all time,” and not because he won the Nobel Prize in Chemistry a decade earlier for explaining the nuts and bolts of ozone formation. It was his blunt truthfulness and ecological advocacy that earned the organization’s respect.

Paul Crutzan is no longer alive. He died on February 4, 2021 in Mainz, Germany at the age of 87. What attracted the 86 year old “Green Pope” to Paul were three factors that were lauded at his death in the Proceedings of the National Academy of Sciences (PNAS) – “the disruptive advancement of science, the inspiring communication of science, and the responsible operationalization of science.”

It didn’t hurt that Crutzan was pleasant – or as the The Royal Society in its obituary simply described him: “a warm hearted person and a brilliant scientist.”

In 2015, he was Pope Francis’s right arm when the Catholic leader, who had purposefully chosen the name of the Patron Saint of Ecology as his own, was briefed on the Anthropocene Epoch. Crutzen had christened the label five years earlier to brand a post-human planet that was not faring well.

Crutzen was one of 74 scientists from 27 nations and Taiwan who formed the elite Pontifical Academy of Sciences in 2015. Those selected were a Who’s Who of the world’s scientific All-Stars including 14 Nobel recipients, and notables like Microbiologist Werner Arber, physicist Michael Heller, geneticist Beatrice Mintz, biochemist Maxine Singer, and astronomer Martin Rees.

On May 24, 2015, they delivered their climate conclusions to the Pope, face to face. The Pope heard these words, “We have a collection of experts from around the world who are concerned about climate change. The changes are already happening and getting worse, and the worst consequences will be felt by the world’s 3 billion poor people.”

The next month, with his release of the encyclical on the environment, Laudato Si’, Pope Francis began by embracing science, with these words, “I am well aware that in the areas of politics and philosophy there are those who firmly reject the idea of a Creator, or consider it irrelevant, and consequently dismiss as irrational the rich contribution which religions can make towards an integral ecology and the full development of humanity. Others view religions simply as a subculture to be tolerated. Nonetheless, science and religion, with their distinctive approaches to understanding reality, can enter into an intense dialogue fruitful for both.”

Further along, he celebrates scientific progress with these remarks, “We are the beneficiaries of two centuries of enormous waves of change: steam engines, railways, the telegraph, electricity, automobiles, aeroplanes, chemical industries, modern medicine, information technology and, more recently, the digital revolution, robotics, biotechnologies and nanotechnologies. It is right to rejoice in these advances and to be excited by the immense possibilities which they continue to open up before us”

But then comes the hammer: “Any technical solution which science claims to offer will be powerless to solve the serious problems of our world if humanity loses its compass, if we lose sight of the great motivations which make it possible for us to live in harmony, to make sacrifices and to treat others well.”

HHS Again Suspends Disbelief: The Medicaid Program Will Ignore the Greatest Health Threat to Medicaid Beneficiaries

Jul 12, 2023

BY DAVID INTROCASO

In May the Centers for Medicare and Medicaid Services (CMS) simultaneously published two proposed Medicaid rules (here and here) intended to improve moreover access and quality. Both discussed at length the agency’s commitment to “addressing health equity.” The first sentence in both identified health equity as a Medicaid program priority. The proposed “ensuring access” rule stated CMS “takes a comprehensive approach to . . . better addressing health equity issues in the Medicaid program.” CMS went on to state “we are working to advance health equity by designing, implementing, and operationalizing policies and programs” by “eliminating avoidable differences in health and quality of life outcomes experienced by people who are disadvantaged or underserved.”

Nevertheless, CMS’ interest in health equity is entirely performative. It is impossible to believe the agency is legitimately interested in “eliminating avoidable differences” because leadership is well aware the greatest health equity threat to Medicaid – and Medicare – beneficiaries is the climate crisis. This is because the most climate vulnerable Americans are Medicaid and Medicare populations. Yet, the climate crisis is never addressed much less mentioned in either proposed Medicaid rule. The word “climate” never appears in 291 Federal Register pages.

This is explained by the fact that despite the Biden administration’s “government-wide approach” approach to “tackle” the climate crisis, HHS has refused to address the threat the climate crisis poses by regulating the healthcare industry’s massive carbon footprint.

Children, 36 percent of whom are Medicaid beneficiaries, are uniquely vulnerable. Fine respirable particles resulting from fossil fuel combustion are particularly harmful because children breathe more air than adults relative to their body weight. Research published last year concluded the health effects to the fetus, infant and child include preterm and low-weight birth, infant death, hypertension, kidney and lung disease, immune-system dysregulation, structural and functional changes to the brain and a constellation of behavioral health diagnoses.

Medicare beneficiaries, already compromised due to higher incidence rates of co-morbidities, are at even greater risk related to arthropod-borne, food-borne and water-borne diseases because the climate crisis can increase the severity of over half of known human pathogenic diseases. Extreme heat episodes are particularly deadly. Over the past 20 years heat-related mortality among seniors has increased 54%.

Air, Air, Everywhere, and Not a Breath Safe to Take

Jun 14, 2023

BY KIM BELLARD

If you live, as I do, anywhere in the Eastern half of the country, for the past week you’ve probably been thinking about something you’re not used to: wildfires. Sure, we’ve all been aware of how wildfires routinely plague the West Coast, particularly Oregon and Washington, but it’s novel for the East. So when the smoke from Canadian wildfires deluged cities through the East and Midwest, it came as kind of a shock.

For a day last week, New York City supposedly had the worst air quality in the world. The next day Philadelphia had that dubious distinction. The air quality index in those cities, and many others, got into the “Maroon” level, which means it was hazardous for everyone. Not just for the elderly and other “sensitive” groups, and not just some risk for some people, but hazardous for everyone.

If you didn’t know about AirNow.gov before, you should now.

New Yorkers are used to smog and air quality that is less than idyllic, but smoke from wildfires, containing fine particulates that easily get into the lungs, weren’t something anyone was prepared for. “Wildfires were not really a scenario, in all honesty, that I recall us specifically contemplating,” Daniel Kass, New York City’s deputy commissioner for environmental health from 2009 to 2016, admitted to NBC News.

“People on the East Coast aren’t used to seeing these types of situations. There was a much slower response,” Peter DeCarlo, an associate professor of environmental health and engineering at Johns Hopkins University, also told NBC News. “We can probably learn a thing or two from our West Coast friends.”

Climate Change: The Future of the Quality Movement

Nov 18, 2021

By MARIE DUNN

A little more than 20 years ago, the IOM report To Err is Human catalyzed the profession around the realization that our health care system was killing around 98,000 people a year from medical error. I am part of a generation of professionals that learned to adopt systems thinking; to measure, monitor, and improve; and to ultimately improve quality of care.

Today, we face a different set of challenges. Health care is in the midst of a global pandemic, a reckoning with systemic racism, not to mention the great resignation. But also, we face a climate crisis. Are these things connected? Is there something we all can do? The answer is undoubtedly yes, and I write to advocate for climate change to be included on this list of strategic and moral imperatives for health care leaders everywhere.

Why is that?

Climate Change is not an ‘Equal Opportunity’ Crisis

Oct 28, 2019• 3

By PHUOC LE, MD and SAM APTEKAR

In the last fifteen years, we have witnessed dozens of natural disasters affecting our most vulnerable patients, from post-hurricane victims in Haiti to drought and famine refugees in Malawi. The vast majority of these patients suffered from acute on chronic disasters, culminating in life-threatening medical illnesses. Yet, during the course of providing clinical care and comfort, we rarely, if ever, pointed to climate change as the root cause of their conditions. The evidence for climate change is not new, but the movement for climate justice is now emerging on a large scale, and clinicians should play an active role.

Let’s be clear: there is no such thing as an “equal opportunity” disaster. Yes, climate change poses an existential threat to us all, but not on equal terms. When nature strikes, it has always been the poor and historically underserved who are most vulnerable to its wrath. Hurricane Katrina provides an example of how natural disasters target their victims along racial and socioeconomic lines even in the wealthiest nations. Writes TalkPoverty.org, “A black homeowner in New Orleans was more than three times as likely to have been flooded as a white homeowner. That wasn’t due to bad luck; because of racially discriminatory housing practices, the high-ground was taken by the time banks started loaning money to African Americans who wanted to buy a home.” Throughout the world, historically marginalized communities have been pushed to overcrowded, poorly-built, and unsanitary neighborhoods where natural disasters invoke much greater harm.

The IPCC Confirms Life As We Know It Will Soon Cease to Exist

Nov 6, 2018• 7

By DAVID INTROCASO PhD

THCB readers may recall last year in early June when the Trump administration announced it would withdraw from the 2015 Paris climate accord and earlier this January when the World Economic Forum met to discuss its global risk report that included the chapter, “Our Planet on the Brink,” I discussed in part (here and here) the health care industry’s indifference to global warming (See also my related 3 Quarks Daily essay.) Now comes the United Nation’s Intergovernmental Panel on Climate and Change’s (IPCC’s ) latest report. Once again overwhelming scientific evidence that confirms life as we know it on this planet will soon cease to exist is received with apathetic insouciance.

Created in 1988 the IPCC is considered the world’s definitive scientific body on climate change and co-winner with Al Gore of the 2007 Nobel Peace Prize, finalized in early October its report, “Global Warming of 1.5°C.” The 2015 Paris accord called for the report. It was prepared by nearly one hundred scientists who analyzed thousands of the most recent scientific evidence. The report’s summary was accepted by over 180 countries including the American and Saudi Arabia delegation during the IPCC’s meeting recently concluded in South Korea.

What is newsworthy about the IPCC report is its conclusion that keeping or holding temperature increases below 2°C, the goal of the Paris agreement, would not avoid the catastrophic effects of global warming. At 1.5°C life on this planet would suffer serious or dire harm, at 2°C catastrophic harm. Specifically, the report compared the impact between a 1.5°C (2.7°F) increase in temperature with a 2°C (3.6°F) increase (The earth has already warmed by 1°C since the pre-industrial era). Among numerous other findings, should temperatures increase to 1.5°C, the report found of 105,000 species studied, four percent of vertebrates (that include us), eight percent of plants and six percent of insects would lose half of their climatically-determined geographic range. At 2°C, the percents double to triple. Global crop yields will decline significantly. At 1.5°C we will lose 70 to 90 percent of coral reefs, at 2°C there will be a 99 percent loss. At 1.5°C Marine fishery losses or the global annual catch loss would be 1.5 million tons, at 2°C they double.

Global Risk Report: Davos, Trump and Climate Change

Feb 6, 2018

By DAVID INTROCASO

During the recent World Economic Forum in Davos, Switzerland, President Trump once again noted his objection to the Paris climate accord. In an interview with Piers Morgan, Trump again called it a “horrible deal” because, as has been widely reported, climate change or global warming is, per the president, a “hoax” perpetrated by the Chinese. “There is cooling and there’s a heating – I mean look,” Trump explained to Morgan, “it use to not be climate change. It used to be global warming. That wasn’t working too well because it was getting too cold all over the place. The ice caps were going to melt. They were going to be gone by now, but now they’re setting records, okay?”

Trump was asked about climate change because the topic was on the Forum’s agenda. Not surprisingly, in the days leading up to the confab, climate scientists once again found the proceeding calendar year one of the warmest on record. NASA ranked 2017 the second warmest since 1880 (or since reliable record keeping began), or after 2016. NOAA, using a slightly different methodology, ranked it the third warmest after 2016 and 2015 respectively. Not only were the last three years the warmest on record, the five warmest years on record have occurred since 2010, 17 of the 18 warmest since 2001 and last year marked the 21^st consecutive year the contiguous United States had above average temperatures. Record 2017 temperatures were somewhat unanticipated however because of the lack of an El Niño (or Pacific trade wind), effect that is associated with increased global temperatures. Because air temperatures are largely determined by ocean temperatures, also not surprisingly the five warmest ocean temperature years recorder have been 2017, 2015, 2016, 2014 and 2013 respectively. Ocean temperatures in 2017 were exceptionally warm. Measured as heat energy in Joules, 2017 ocean temperatures exceeded 2015 by 1.51 x 10^22 Joules, or the amount of electrical energy China produces annually.
