All known life is homochiral. DNA and RNA are made from “right-handed” nucleotides, and proteins are made from “left-handed” amino acids. Driven by curiosity and plausible applications, some researchers had begun work toward creating lifeforms composed entirely of mirror-image biological molecules. Such mirror organisms would constitute a radical departure from known life, and their creation warrants careful consideration. The capability to create mirror life is likely at least a decade away and would require large investments and major technical advances; we thus have an opportunity to consider and preempt risks before they are realized. Here, we draw on an in-depth analysis of current technical barriers, how they might be eroded by technological progress, and what we deem to be unprecedented and largely overlooked risks (1). We call for broader discussion among the global research community, policy-makers, research funders, industry, civil society, and the public to chart an appropriate path forward.

This report describes the technical feasibility of creating mirror bacteria and the potentially serious and wide-ranging risks that they could pose to humans, other animals, plants, and the environment. It accompanies the Science Policy Forum article titled “Confronting risks of mirror life”, published December 12, 2024.

Le changement climatique arrive une nouvelle fois en tête des préoccupations tant des experts que des citoyens interrogés par Axa pour sa 11e édition de son "Future Risks Report", publié jeudi.

Under current emission trajectories, temporarily overshooting the Paris global warming limit of 1.5 °C is a distinct possibility. Permanently exceeding this limit would substantially increase the probability of triggering climate tipping elements. Here, we investigate the tipping risks associated with several policy-relevant future emission scenarios, using a stylised Earth system model of four interconnected climate tipping elements.

The big question: Would climate engineering like sending reflective particles into the stratosphere or brightening clouds help reduce the national security risks of climate change or make them worse?

Dangers of wildfires, extreme weather and other factors outgrowing preparedness, European Environment Agency says

The role of health professionals In January 2023, the science and security board of the Bulletin of the Atomic Scientists moved the hands of the doomsday clock forward to 90 seconds before midnight, reflecting the growing risk of nuclear war.1 In August 2022, the UN secretary general, António Guterres, warned that the world is now in “a time of nuclear danger not seen since the height of the Cold War.”2 The danger has been underlined by growing tensions between many nuclear armed states.13 As editors of health and medical journals worldwide, we call on health professionals to alert the public and our leaders to this major danger to public health and the essential life support systems of the planet—and urge action to prevent it. Current nuclear arms control and non-proliferation efforts are inadequate to protect the world’s population against the threat of nuclear war by design, error, or miscalculation. The Treaty on the Non-Proliferation of Nuclear Weapons (NPT) commits each of the 190 participating nations

Simultaneous harvest failures across major crop-producing regions are a threat to global food security. Concurrent weather extremes driven by a strongly meandering jet stream could trigger such events, but so far this has not been quantified. Specifically, the ability of state-of-the art crop and climate models to adequately reproduce such high impact events is a crucial component for estimating risks to global food security. Here we find an increased likelihood of concurrent low yields during summers featuring meandering jets in observations and models. While climate models accurately simulate atmospheric patterns, associated surface weather anomalies and negative effects on crop responses are mostly underestimated in bias-adjusted simulations. Given the identified model biases, future assessments of regional and concurrent crop losses from meandering jet states remain highly uncertain. Our results suggest that model-blind spots for such high-impact but deeply-uncertain hazards have to be anticipated and acc

State Farm will almost entirely stop issuing new policies in California – with climate-exacerbated wildfires and bad public policy a large reason why

The world is at risk of descending into a climate “doom loop”, a thinktank report has warned. It said simply coping with the escalating impacts of the climate crisis could draw resources and focus away from the efforts to slash carbon emissions, making the situation even worse.

The Center for Climate and Security (CCS), a non-partisan institute of the Council on Strategic Risks, has a team and distinguished Advisory Board of security and military experts. CCS envisions a climate-resilient world which recognizes that climate change threats to security are already significant, unprecedented and potentially existential, and acts to address those threats in a manner that is commensurate to their scale, consequence and probability.

Prior research has posed a paradox of sorts: if the risk to humanity from natural hazards is so large, then why do we exist? The human species has existed for about 200,000 years, and our ancestors for even longer. Natural hazards have existed throughout this time. If they posed a significant risk, then humanity probably would have been wiped out a long time ago—yet here we are. Prior research has taken this observation about deep human history to imply a low ongoing global catastrophic risk from natural hazards, especially in comparison to anthropogenic hazards.

Civil unrest, political instability, food insecurity, mass migration and worsening human rights are the baked-in secondary impacts of climate change, but you wouldn’t know that from the undercooked approach of governments and business. As the extreme weather events the world is already experiencing become more frequent, they will trigger a cascade of these second-order climate risks across a huge swathe of countries.

Climate tipping points in the Antarctica, the Arctic and the Amazon are at risk of being reached before or at the current level of global warming of 1.2 degrees Celsius, requiring a “major rethink” of global climate goals and the action necessary to achieve them, according to a recent report.

Momentum to phase out unabated coal use is growing globally. This transition is critical to meeting the Paris climate goals but can potentially lead to large amounts of stranded assets, especially in regions with newer and growing coal fleets. Here we combine plant-level data with a global integrated assessment model to quantify changes in global stranded asset risks from coal-fired power plants across regions and over time. With new plant proposals, cancellations, and retirements over the past five years, global net committed emissions in 2030 from existing and planned coal plants declined by 3.3 GtCO2 (25%). While these emissions are now roughly in line with initial Nationally Determined Contributions (NDCs) to the Paris Agreement, they remain far off track from longer-term climate goals. Progress made in 2021 towards no new coal can potentially avoid a 24% (503 GW) increase in capacity and a 55% ($520 billion) increase in stranded assets under 1.5 °C. Stranded asset risks fall disproportionately on emergin

The UK is one of the world's most nature-depleted countries - in the bottom 10% globally and last among the G7 group of nations, new data shows. It has an average of about half its biodiversity left, far below the global average of 75%, a study has found.
