Collapse has historically benefited the 99%. […] That’s the amazing conclusion of Luke Kemp, author of Goliath’s Curse: The History and Future of Societal Collapse. Luke is a research associate at the Centre for the Study of Existential Risk at the University of Cambridge, and has spent the past five years studying the collapse of civilisations throughout history. He joins me to explain his research, detailing the difference between complex, collective civilisations and what he calls “Goliaths”, massive centralising forces by which a small group of individuals extract wealth from the rest through domination and the threat of violence. Today, he says, we live in a global Goliath.
Four key parts of the Earth’s climate system are destabilising, according to a new study with contributions from the Potsdam Institute for Climate Impact Research (PIK). Researchers analysed the interconnections of four major tipping elements: the Greenland ice sheet, the Atlantic meridional overturning circulation (AMOC), the Amazon rainforest and the South American monsoon system. All four show signs of diminished resilience, raising the risk of abrupt and potentially irreversible changes.
Conservative leader Kemi Badenoch has described her plan to “maximise extraction” of the UK’s oil and gas from the North Sea as a “common sense” energy policy. Politicians are using language like this increasingly often – calling themselves “pragmatic” on climate change and invoking “common sense”. It sounds reasonable, reassuring, and grownup – the opposite of “hysterical” campaigners or “unrealistic” targets.
Scientists say ‘shocking’ discovery shows rapid cuts in carbon emissions are needed to avoid catastrophic fallout
Purpose Animal emissions account for nearly 60% of total greenhouse gas emissions from the livestock sector. To estimate these emissions, the Food and Agriculture Organization of the United Nations (FAO) developed a dedicated module within the Global Livestock Environmental Assessment Model (GLEAM). Although previous studies have explored selected inputs for specific animals and emission types, a comprehensive analysis of all 92 inputs (parameters and emission factors) had not been conducted. This study aimed to identify the most influential inputs affecting ruminant emissions in GLEAM.
The world will warm more than expected due to future changes in ozone, which protects the Earth from harmful sun rays but also traps heat as it is a greenhouse gas. While banning ozone-destroying gases such as CFCs has helped the ozone layer to recover, when combined with increased air pollution the impact of ozone could warm the planet 40% more than originally thought.
A common pesticide can increase children’s risk of poor brain development and motor skills Kids exposed to chlorpyrifos while in the womb have altered neuron development and lower blood flow to their brains This can cause problems with motor skills among children
Bad climate news is everywhere. Africa is being hit particularly hard by climate change and extreme weather, impacting lives and livelihoods. We are living in a world that is warming at the fastest rate since records began. Yet, governments have been slow to act.

Planet Earth is living on borrowed time, a new global report reveals. The world must stop burning fossil fuels now and take urgent steps to reduce global warming.
Heat caused 2,300 deaths across 12 cities, of which 1,500 were down to climate crisis, scientists say
Research in Chile suggests climate crisis makes eruptions more likely and explosive, and warns of Antarctica risk
Ocean acidification has already crossed a crucial threshold for planetary health, scientists say in unexpected finding
Under existing climate policies, global temperatures are projected to reach 2.7 degrees Celsius (4.9F) above pre-industrial levels by 2100—a pathway that would ultimately erase 76% of current glacier mass over the coming centuries. But if warming is held to the Paris Agreement's 1.5C target, 54% of glacial mass could be preserved, according to the study, which combined outputs from eight glacier models to simulate ice loss across a range of future climate scenarios.
A new study uncovers Earth’s deep temperature history and shows just how tightly carbon dioxide has always controlled the climate
The world's largest polluters are also the safest from the environmental damage they help create—while the countries least to blame face the greatest threats, including the increased possibility of violent conflict.
Toxic pollution from wildfires has infiltrated the homes of more than a billion people a year over the last two decades, according to new research. The climate crisis is driving up the risk of wildfires by increasing heatwaves and droughts, making the issue of wildfire smoke a “pressing global issue”, scientists said.

Paper in Nature Climate Change journal reveals major role wealthy emitters play in driving climate extremes. The world’s wealthiest 10% are responsible for two-thirds of global heating since 1990, driving droughts and heatwaves in the poorest parts of the world, according to a study.
Have you ever thought about what would happen if all life in the ocean disappeared? A recent study explores this extreme scenario to understand how ocean biology shapes the past, present, and future climate. The ocean plays a critical role in regulating Earth's climate. It is a massive carbon store that absorbs about 25% of human-caused emissions and thus helps maintain a relatively low CO2 level in the atmosphere. But what would happen if all marine life—from the tiniest plankton to the largest whales—disappeared? A recent study delves into this extreme scenario to uncover the crucial role that ocean biology plays in mitigating climate change.

Study Finds Synergistic Convergence of Global Warming, Pesticide Toxicity, and Antibiotic Resistance
- Beyond PesticidesSpringtails illustrate in new research how global warning and antibiotic resistance creates synergistic effects: warming increases pesticide toxicity, triggering antibiotic resistance which spreads through horizontal gene transfer and predation.
It is said that George W. Bush Jr. decided to invade Iraq in 2003 because he had read some papers on oil depletion by the Association for the Study of Peak Oil (ASPO). Of course, it may be just a legend, but I don’t see it as impossible, and perhaps not even improbable. Politicians make decisions on the basis of vague ideas, often on the spur of the moment, and in many cases making terrible mistakes. But they normally understand some of the critical elements that keep alive the system. For the US, the critical resource was, and still is, crude oil. So, it is possible that Bush thought that it was necessary to compensate for the decline of the US oil production by seizing the Iraqi resources. That didn’t necessarily imply to start a war, just like filling the tank of your car doesn’t imply shooting dead the service station operator. But that’s the way some people’s minds work.
A Dartmouth College research team came up with the estimated pollution caused by 111 companies, with more than half of the total dollar figure coming from 10 fossil fuel providers: Saudi Aramco, Gazprom, Chevron, ExxonMobil, BP, Shell, National Iranian Oil Co., Pemex, Coal India and the British Coal Corporation. For comparison, $28 trillion is a shade less than the sum of all goods and services produced in the United States last year.
Eat-Lancet report recommended shift to more plant-based, climate-friendly diet but was extensively attacked online [...] The report recommended that if global red meat eating was cut by 50%, the “planetary health diet” would provide nutritious food to all while tackling the harms caused by animal agriculture, which accounts for over 14% of all greenhouse gas emissions worldwide. It suggested individuals – particularly in wealthy countries – should increase their consumption of nuts, pulses and other plant-based foods while cutting meat and sugar from their diets.
The exponential rise in microplastic pollution over the past 50 years may be reflected in increasing contamination in human brains, according to a new study. It found a rising trend in micro- and nanoplastics in brain tissue from dozens of postmortems carried out between 1997 and 2024. The researchers also found the tiny particles in liver and kidney samples.
Human-caused climate change increased the likelihood and intensity of the hot, dry and windy conditions that fanned the flames of the recent devastating Southern California wildfires, a scientific study found. But the myriad of causes that go into the still smoldering fires are complex, so the level of global warming's fingerprints on weeks of burning appears relatively small compared to previous studies of killer heat waves, floods and droughts by the international team at World Weather Attribution. Tuesday's report, too rapid for peer-review yet, found global warming boosted the likelihood of high fire weather conditions in this month's fires by 35% and its intensity by 6%.
The researchers estimated an extra 8,000 people would die each year as a result of “suboptimal temperatures” even under the most optimistic scenario for cutting planet-heating pollution. The hottest plausible scenario they considered showed a net increase of 80,000 temperature-related deaths a year.

This research reinforces the scientific consensus that the only viable strategy to limit catastrophic climate change requires drastic and immediate emissions cuts. An important study was published last month in the journal Nature, titled “Overconfidence in climate overshoot.” While increasingly dire warnings of the catastrophic impacts of global climate change continue to be published by scientists, the findings of this new paper provide another stark reminder of the urgent necessity to limit global warming by immediately reducing greenhouse gas (GHG) emissions.

The signs of weakening resilience raise concerns that the world’s greatest tropical forest – and biggest terrestrial carbon sink – is degrading towards a point of no return. It follows four supposedly “one-in-a-century” dry spells in less than 20 years, highlighting how a human-disrupted climate is putting unusually intense strains on trees and other plants, many of which are dying of dehydration.

Since 2007, conditions in the Arctic have shifted, as confirmed by data recently published in the journal Communications Earth & Environment. Between 2007 and 2021, the marginal zones of the Arctic Ocean experienced 11 marine heat waves, producing an average temperature rise of 2.2 degrees Celsius above seasonal norm and lasting an average of 37 days. Since 2015, there have been Arctic marine heat waves every year.

RealClimate: A new paper was published in Science Advances today. Its title says what it is about: "Physics-based early warning signal shows that AMOC is on tipping course." The study follows one by Danish colleagues which made headlines last July, likewise looking for early warning signals for approaching an AMOC tipping point (we discussed it here),
Scientists now have a better understanding of the risks ahead and a new early warning signal to watch for.
Collapse in system of currents that helps regulate global climate would be at such speed that adaptation would be impossible
Disruption of the Atlantic Meridional Overturning Current could freeze Europe, scorch the tropics and increase sea level rise in the North Atlantic. The tipping point may be closer than predicted in the IPCC’s latest assessment.

Total is 20% higher than thought and may have implications for collapse of globally important north Atlantic ocean currents The Greenland ice cap is losing an average of 30m tonnes of ice an hour due to the climate crisis, a study has revealed, which is 20% more than was previously thought. Some scientists are concerned that this additional source of freshwater pouring into the north Atlantic might mean a collapse of the ocean currents called the Atlantic meridional overturning circulation (Amoc) is closer to being triggered, with severe consequences for humanity.

f global warming reaches or exceeds two degrees Celsius by 2100, University of Western Ontario's Joshua Pearce says it is likely that mainly richer humans will be responsible for the death of roughly one billion mainly poorer humans over the next century. The oil and gas industry, which includes many of the most profitable and powerful businesses in the world, is directly and indirectly responsible for more than 40% of carbon emissions—impacting the lives of billions of people, many living in the world's most remote and low-resourced communities. A new study proposes aggressive energy policies that would enable immediate and substantive decreases to carbon emissions and recommends a heightened level of government, corporate and citizen action to accelerate the decarbonization of the global economy, aiming to minimize the number of projected human deaths.

The Greenland Ice Sheet covers 1.7 million square kilometers (660,200 square miles) in the Arctic. If it melts entirely, global sea level would rise about 7 meters (23 feet), but scientists aren't sure how quickly the ice sheet could melt. Modeling tipping points, which are critical thresholds where a system behavior irreversibly changes, helps researchers find out when that melt might occur.

Heat and cold are now established health risk factors, with several studies reporting important mortality effects in populations around the world.1, 2, 3 The associated health burden is expected to increase with climate change, especially under the most extreme scenarios of global warming.4, 5 However, robust estimates of excess mortality in the current and future periods are still challenging to obtain due to the numerous factors influencing vulnerability to heat and cold, including climatic, environmental, and socioeconomic conditions.6 These factors represent the main drivers of variation in mortality risks, which have been shown to differ geographically and across age groups.

MIT researchers have confirmed that Earth harbors a “stabilizing feedback” mechanism that acts over hundreds of thousands of years to keep global temperatures within a steady, habitable range.“On the one hand, it’s good because we know that today’s global warming will eventually be canceled out through this stabilizing feedback,” says Constantin Arnscheidt, a graduate student in MIT’s Department of Earth, Atmospheric and Planetary Sciences (EAPS). “But on the other hand, it will take hundreds of thousands of years to happen, so not fast enough to solve our present-day issues.”

Filter-feeding whales are consuming millions of particles of microplastic pollution a day, according to a study, making them the largest consumers of plastic waste on the planet. The central estimate for blue whales was 10m pieces a day, meaning more than 1bn pieces could be ingested over a three- to four-month feeding season. The weight of plastic consumed over the season was estimated at between 230kg and 4 tonnes.
National climate pledges would collectively require 1.2 billion hectares (about 3 billion acres) of land, researchers have found in a new study, The Land Gap Report. More than half of this land is already currently used for something else. This demand for land will put pressure on ecosystems, Indigenous lands, small farmers and food security. Protecting existing forests and securing Indigenous and community land rights are more effective than carbon capture plans requiring land-use change, including reforestation.

Countries should move from coal to renewable energy without shifting to gas as a “transition” fuel to save money, as high gas prices and market volatility have made the fossil fuel an expensive option, analysis has found. Natural gas has long been touted as a “transition” fuel for economies dependent on coal for their power needs, as it has lower carbon dioxide emissions than coal but requires similar centralised infrastructure, and gas-fired power stations take only a couple of years to build. Earlier this year, before Russia invaded Ukraine, the European Commission angered green campaigners by including gas as a “bridge” to clean energy in its guidebook for green investment.

Metals will play a central role in successfully building Europe’s clean technology value chains and meeting the EU’s 2050 climate-neutrality goal. In the wake of supply disruptions from the COVID-19 pandemic and Russia's invasion of Ukraine, Europe’s lack of resilience for its growing metals needs has become a strategic concern. This study evaluates how Europe can fulfil its goal of “achieving resource security” and “reducing strategic dependencies” for its energy transition metals, through a demand, supply, and sustainability assessment of the EU Green Deal and its resource needs . It concludes that Europe has a window of opportunity to lay the foundation for a higher level of strate- gic autonomy and sustainability for its strategic metals through optimised recycling, domestic value chain investment, and more active global sourcing. But firm action is needed soon to avoid bottlenecks for several materials that risk being in global short supply at the end of this decade.
