Rainwater almost everywhere on Earth has unsafe levels of ‘forever chemicals’, according to new research.
Per- and poly-fluoroalkyl substances (PFAS) are a large family of human-made chemicals that don’t occur in nature. They are known as ‘forever chemicals’ because they don’t break down in the environment.
They have non-stick or stain repellent properties so can be found in household items like food packaging, electronics, cosmetics and cookware.
But now researchers at the University of Stockholm have found them in rainwater in most locations on the planet – including Antarctica. There is no safe space to escape them.

A group of climate scientists warn that the potential for humanity’s mass extinction has been dangerously underexplored. On this week’s On the Media, we hear how facing our planet’s fragility could inspire hope, instead of despair, and a physicist explains how creation stories are essential for understanding our place in the universe.

Abstract
Prudent risk management requires consideration of bad-to-worst-case scenarios. Yet, for climate change, such potential futures are poorly understood. Could anthropogenic climate change result in worldwide societal collapse or even eventual human extinction? At present, this is a dangerously underexplored topic. Yet there are ample reasons to suspect that climate change could result in a global catastrophe. Analyzing the mechanisms for these extreme consequences could help galvanize action, improve resilience, and inform policy, including emergency responses. We outline current knowledge about the likelihood of extreme climate change, discuss why understanding bad-to-worst cases is vital, articulate reasons for concern about catastrophic outcomes, define key terms, and put forward a research agenda. The proposed agenda covers four main questions: 1) What is the potential for climate change to drive mass extinction events? 2) What are the mechanisms that could result in human mass mortality and morbidity? 3) What are human societies’ vulnerabilities to climate-triggered risk cascades, such as from conflict, political instability, and systemic financial risk? 4) How can these multiple strands of evidence—together with other global dangers—be usefully synthesized into an “integrated catastrophe assessment”? It is time for the scientific community to grapple with the challenge of better understanding catastrophic climate change.

The world is now enduring greater stress than any time in recent decades, according to U.N. Secretary-General António Guterres. And while humanity has so far avoided “the suicidal mistake of nuclear conflict,” he said, tensions are hitting new highs at a time when many lessons of the past seem forgotten.
“Today, humanity is just one misunderstanding, one miscalculation away from nuclear annihilation,” the world’s top diplomat said at a U.N. conference on the non-proliferation of nuclear weapons in New York City.
It’s not the first time such a dire warning has been issued about the catastrophic risks posed by nuclear weapons. Here’s a brief look at why Guterres and others are raising the alarm now: LINK

Blistering heatwaves are just the start. We must accept how bad things are before we can head off global catastrophe, according to a leading UK scientist
The collapse of the USSR brought about a period within Russia of unbridled chaos, devolving into a free-for-all amongst citizens unsure where their next meal might be coming from. Everything that could have been stolen, was stolen, and included in that were up to 400 nuclear weapons. But where did all of these weapons end up, and how secure is the rest of Russia’s apocalyptic arsenal today? Will the nuclear black market be responsible for the next major terrorist attack? On the panel this week – Robin M Frost – (Uni. of Ottawa) – Eric Gomez – (CATO) – Foeke Postma – (Bellingcat) – Andrew Futter – (Uni. of Leicester) Follow the show on @TheRedLinePod Follow Michael on @MikeHilliardAus For more information please visit – www.theredlinepodcast.com
Robin M Frost begins our conversation with a look at the chaos of the collapse of the Soviet Union, which included nuclear sites in former Soviet states that were widely secret from the public until the end of the Cold War.
We discuss the realistic concerns about the security of these former sites, which independent investigations have proven to be extremely lax in security and operational protocols, and how much of a risk they pose for the nuclear black market.
What has stopped non-state actors who would want to use a nuclear weapon in an attack? Frost identifies a number of factors, including the difficulty of obtaining and fashioning enriched uranium into a suitable configuration for a weapon, the difficulty of constructing the triggers necessary to detonate, and the sophisticated knowledge required to build such a weapon.
The threat of “salting” a regular explosive device with spent radioactive materials, a radiological weapon, is a much more realistic threat according to Frost and could be created using much more readily available materials kept under significantly less security across the globe.
Interestingly, the IAEA notes that organised crime in the former Soviet Union has avoided dealing in nuclear materials, with Frost speculating both fear of handling the materials, the attention that would be brought upon their
Part 2: Recorking the Champagne (27:12)
Eric Gomez asserts that nuclear safety protocols are stronger than the public consensus seems to believe, backed up through the lack of accidental denotation of nuclear weapons.
Gomez notes the abundance of “tactical nukes” in the former Soviet Union, often forward-deployed with military units, which are small in payload but highly portable and typically featuring less safety protocols (i.e. codes for activation), poses the greatest threat to international safety today. However, many of the components in those weapons have degraded, leading to a questionable potency for those weapons in the current age.
We unpack how the United States security guarantee has served as a deterrent for other countries to develop their own nuclear weapons, but also note the scale of infrastructure (allowing for easy detection) and difficulty to build nuclear weapons is a major factor in preventing the spread of nuclear nations.
Part 3: A Fortified Castle… with a Broken Screen Door (46:02)
Foeke Postma posits that security of facilities and weapons are as strong as the people that guard it, noting the abundance of data in the modern world create highly traceable individuals and reveal the location of sites, transit routes, and other highly sensitive information that can be obtained on the black market.
Postma talks about how social media accounts and fitness devices are regularly used by Open Source Intelligence operatives and journalists to uncover such sensitive information, walking us through his work uncovering how US military personnel inadvertently revealed a multitude of sensitive security protocols about US nuclear weapons and the bases at which they are stored.
Postma notes that governments and potentially non-state actors are no doubt utilising these OS opportunities to map military and intelligence networks, including current members of Russia’s GRU military intelligence service.
Part 4: Dumb Luck (1:08:27)
Andrew Futter notes that while there’s been a combination of luck and success with the security of nuclear weapons facilities, it’s not easy to assess what has been effective so far and what will need to change to continue success in the evolving security environment.
Futter notes the success of the AQ Khan proliferation network allowed for the flow of information about how to achieve a nuclear weapon program to several states with nuclear ambitions, but also demonstrates the scale of work that would be required to successfully launch such a program.
The fear of culpability is likely a major deterrent against states aiding non-state actors in the creation or use of a nuclear weapon, but Futter unpacks the possibility of a state being framed in a false flag attack, through the use of material or markers linked to that state in order to exacerbate tensions or trigger conflict.
We unpack nuclear deterrence theory and how in practice that would work in the modern day, noting that a significant amount of weaponisation would be required to be effective, as well as a certain level of overt testing and demonstration. We also talk about delivery methods and why missiles remain both preferred from a command and control perspective.
