Weather cycle threatens harvests worldwide, adding to inflation already fuelled by the Iran war
European scientists warn of consequences for weather patterns, the global climate and marine life
Drug-resistant bacteria are no longer confined to hospital settings but are spreading into communities in every country
A new report has uncovered the many risks of participating in climate and environmental protests across the world – and how more countries are criminalising and repressing this activity in a bid to keep it in check.
Scientists know how to alter our atmosphere to try and fix climate change, but doing so could bring other potential unintended impacts
Projections of near-term climate change are a potential research tool. However, for that tool to be most useful, the physical basis for a prediction must be made clear. The basis for our projection of record 2026 global temperature is high climate sensitivity, with its implication that aerosol cooling was still increasing during the period 1970-2005. One consequence, global sea surface warming, already has important effects. Causes of climate change must be understood for policy purposes. Figures in this post and our recent papers are continually updated on our website.[1] We are also now on Substack[2].
The Global Justice Project attempts to set out a new vision for global progress in the 21st century: grounding human development and equality in planetary habitability. It explores the conditions under which the world could move toward this horizon and traces an economically and ecologically consistent transition path from 2026 to 2100.
The Global Justice Project is a collective research initiative developed by the World Inequality Lab. Combining comparative historical data series from the World Inequality Database with global input-output tables, environmental accounts, labour force surveys and other sources, the project explores what a just distribution of socio-economic and environmental resources could look like at the global level from 2025 to 2100 – both between and within countries – in a way that is compatible with planetary boundaries. The project partly builds on the analysis and proposals set out in Thomas Piketty’s Brief History of Equality, extending them into a broader and more comprehensive global framework. The Global Justice Project is now available to explore on a dedicated website, that includes an interactive tool to explore the distributional pathways and climate scenarios behind the report.
The Global Justice Report offers a hopeful bargain: tax extreme wealth and replace consumer excess with social and economic security for all
Global effort needed to limit effects of pollution, industrial fishing and climate crisis, World Ocean Assessment says
Brutal El Nino, drought, war threatens food supply
Climate and geopolitical shocks – from El Niño, global heating or wars – hit a food system which already magnifies environmental and social vulnerabilities.
Exclusive: Commission says alert would trigger coordinated international response that could help avoid millions dying. The climate crisis should be declared a global public health emergency by the World Health Organization, or millions more people will die unnecessarily, leading international experts have said. The independent pan-European commission on climate and health, which was convened by the WHO, concluded the climate crisis was such a worldwide threat to health that the WHO should declare it “a public health emergency of international concern” (Pheic).
The European Center for Medium Range Weather Forecasts (ECMWF) earlier this year issued a forecast of a strong (“Super”) El Nino to begin later this year and peak in early 2027, as we have discussed in two earlier posts.3,4 El Ninos are important because of the large effects that they have on global weather, even though those effects are not always consistent from one El Nino to another. El Ninos have even greater effect in combination with ongoing global warming, e.g., Radfar et al.5 find that the combination of an El Nino with increasingly prevalent marine heat waves results in tropical cyclones consistently producing higher maximum wind speeds, storm surges, and precipitation rates, and Liu et al.6 describe evidence of El Ninos strengthened control over global climate anomalies in a warmer world
Beneath the surface of the Pacific, a massive pool of heat is preparing to reshape global weather patterns. Time is running out to prepare for a climate shock of unprecedented scale. As 2026 unfolds, the Pacific Ocean is priming a catastrophic El Niño that threatens to cripple global food systems, trigger widespread economic instability, and shatter planetary temperature records.
Even if global warming does not exceed two degrees, it could lead to more serious consequences than expected. This is the conclusion of a new study published in Nature.
Climate regime shifts (CRSs), characterized by abrupt and persistent transitions between alternative stable states in the climate system, pose serious threats to ecosystems and human well-being. Understanding the potential drivers of CRSs is crucial, particularly in a warming world where CRSs are becoming more frequent.
Climate change is causing measurable harm globally1,2. Political and legal efforts seek to link these damages with specific emissions, including in discussions of loss and damage (L&D)3,4; however, no quantitative definition of L&D exists5,6, nor is there a framework to link past and future emissions from specific sources to monetized, location-specific damages. Here we develop such a framework, which is integrated with recent efforts to estimate the social cost of carbon7. Using empirical estimates of the non-linear relationship between temperature and aggregate economic output, we show that future damages from past emissions—one component of L&D—are at least an order of magnitude larger than historical damages from the same emissions. For instance, one tonne of CO2 emitted in 1990 caused US$180 in discounted global damages by 2020 ($40–530) and will cause an additional $1,840 through 2100 ($500–5,700). Thus, settling debts for past damages will not settle debts for past emissions. In other illustrative esti
The fragility of the global food system fills me with dread – and the war with Iran has exposed just how close to collapse it is
Models are converging on prediction of an El Nino beginning this year, peaking in early 2027. After overlooking the possibility of an El Nino this year, some reporting is jumping on a “Super El Nino” bandwagon. El Nino strength and frequency are important, especially the issue of whether these are modified by global warming. However, the more important knowledge that needs to be extracted from near-term global warming concerns interpretation of ongoing, extraordinary, acceleration of ocean surface warming. Impacts of this ocean warming include a factor of two greater warming over land, increased extreme precipitation, and poleward movement of subtropical conditions.
