Dr Luke Kemp is a Research Associate at the Centre for the Study of Existential Risk, University of Cambridge. He has a PhD in international relations from the ANU and previous experience as a senior economist at Vivid Economics. This episode explores catastrophic and extinction risk, why the topic is understudied, and how we can weigh out the catastrophic risks of climate change and solar geo-engineering.
We already have plenty of evidence of what happens when things better left to governments — which in this case might decide to never flip the switch at all — are ceded to private industry.
We report striking discoveries of numerous seafloor seeps of climate-reactive fluid and gases in the coastal Ross Sea, indicating this process may be a common phenomenon in the region. We establish the recent emergence of many of these seep features, based on their discovery in areas routinely surveyed for decades with no previous seep presence. Additionally, we highlight impacts to the local benthic ecosystem correlated to seep presence and discuss potential broader implications. With these discoveries, our understanding of Antarctic seafloor seeps shifts from them being rare phenomenon to seemingly widespread, and an important question is raised about the driver of seep emergence in the region. While the origin and underlying mechanisms of these emerging seep systems remains unknown, similar processes in the paleo-record and the Arctic have been attributed to climate-driven cryospheric change. Such a mechanism may be widespread around the Antarctic Continent, with concerning positive feedbacks that are curr
We are an international group of researchers and practitioners interested in the emerging fields of post-growth and ecological macroeconomics. Our aim is to advance economic theory, methodology and policy in order to adequately address some of the biggest challenges of our time: climate change, rising inequality, and financial instability.

blue whale vocalizations dropped by almost 40 percent, according to the study, with populations of krill and anchovy collapsing. "When you really break it down, it’s like trying to sing while you're starving," Ryan explained. "They were spending all their time just trying to find food."

Heat waves that already affect the population of the Metropolitan Area of Barcelona (AMB) could significantly intensify in the future, with temperature increases of up to 6ºC and a general reduction in relative humidity in cities by the end of the century.
Heat caused 2,300 deaths across 12 cities, of which 1,500 were down to climate crisis, scientists say
Heatwaves can lead to considerable impacts on societal and natural systems. Accurate simulation of their response to warming is important for adaptation to potential climate futures. Here, we quantify changes of extreme temperatures worldwide over recent decades. We find an emergence of hotspots where the hottest temperatures are warming significantly faster than more moderate temperatures. In these regions, trends are largely underestimated in climate model simulations. Globally aggregated, we find that models struggle with both ends of the trend distribution, with positive trends being underestimated most, while moderate trends are well reproduced. Our findings highlight the need to better understand and model extreme heat and to rapidly mitigate greenhouse gas emissions to avoid further harm.

Despite working on polar science for the British Antarctic Survey for 20 years, Louise Sime finds the magnitude of potential sea-level rise hard to comprehend
A German court has delivered a landmark ruling in a climate lawsuit brought by Peruvian farmer, Saúl Luciano Lliuya, against German energy giant RWE. The German Higher Regional Court of Hamm has ruled that, in principle, companies can be held liable to people halfway around the world for their contribution to the impacts and risks of climate change . While the Court ultimately dismissed Mr Lliuya’s claim, its reasoning represents a significant breakthrough for climate litigation globally. Below we explain what the Court decided, why it matters, and what it might mean in a New Zealand context with Smith v Fonterra still moving through the courts.
Understanding how global mean surface temperature (GMST) has varied over the past half-billion years, a time in which evolutionary patterns of flora and fauna have had such an important influence on the evolution of climate, is essential for understanding the processes driving climate over that interval. Judd et al. present a record of GMST over the past 485 million years that they constructed by combining proxy data with climate modeling (see the Perspective by Mills). They found that GMST varied over a range from 11° to 36°C, with an “apparent” climate sensitivity of ∼8°C, about two to three times what it is today. —Jesse Smith
A new point in history has been reached, entomologists say, as climate-led species’ collapse moves up the food chain even in supposedly protected regions free of pesticides
A new study uncovers Earth’s deep temperature history and shows just how tightly carbon dioxide has always controlled the climate
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.

Young people will be exposed to a number of heatwaves that no one would have experienced in pre-industrial times. Young people will be exposed to a number of heatwaves that no one would have experienced in pre-industrial times.
What if the rules of the game have already sealed our fate? This is a brutal mathematical reality: an unstoppable, self-reinforcing chain reaction in the Earth’s climate system is now underway.
Climate change deaths are largely underreported as the crisis impacts millions and strains an already overburdened healthcare system, according to a new Amnesty International report.
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.
