This article examines the technocentric bias that characterizes climate mitigation literature, focusing on the reports of the IPCC's Working Group III. This bias stems from structural features of the scientific field that prioritizes innovation, leading to the overrepresentation of technological solutions in climate research. Funding mechanisms further reinforce this tendency by incentivizing collaboration with industrial R&D, creating a self-reinforcing loop in which scientific authority and industrial interests converge. The IPCC's institutional positioning—as a policy-relevant yet politically cautious body—amplifies this dynamic by favoring allegedly “cost-effective” technological pathways that lack practical feasibility.

Passing 1.5ºC is now inevitable. Overshoot scenarios tell us that we can relatively safely pass this level but then bring temperatures back down again, but how realistic are they, and how safe?

Climate sensitivity is substantially higher than IPCC’s best estimate (3°C for doubled CO2), a conclusion we reach with greater than 99 percent confidence. We also show that global climate forcing by aerosols became stronger (increasingly negative) during 1970-2005, unlike IPCC’s best estimate of aerosol forcing. High confidence in these conclusions is based on a broad analysis approach. IPCC’s underestimates of climate sensitivity and aerosol cooling follow from their disproportionate emphasis on global climate modeling, an approach that will not yield timely, reliable, policy advice.

A superpower in the fight against global heating is hiding in plain sight. It turns out that the overwhelming majority of people in the world – between 80% and 89%, according to a growing number of peer-reviewed scientific studies – want their governments to take stronger climate action.

The risk of Planetary Insolvency looms unless we act decisively. Without immediate policy action to change course, catastrophic or extreme impacts are eminently plausible, which could threaten future prosperity.

Record emissions, temperatures and population mean more scientists are looking into possibility of societal collapse, report says

We are on the brink of an irreversible climate disaster. This is a global emergency beyond any doubt. Much of the very fabric of life on Earth is imperiled. We are stepping into a critical and unpredictable new phase of the climate crisis. For many years, scientists, including a group of more than 15,000, have sounded the alarm about the impending dangers of climate change driven by increasing greenhouse gas emissions and ecosystem change (Ripple et al. 2020).

Il est de plus en plus évident que le changement climatique modifie nos vies. Mais aujourd'hui, une équipe de l'université d'Hawaï (États-Unis) a publié une étude affirmant que le changement climatique a influencé plus de 200 maladies. L'étude, publiée en août dernier dans la revue scientifique Nature, visait initialement à déterminer si le changement climatique avait influencé l'émergence et la propagation du covid-19, mais elle a été élargie et recoupée avec les données de plus de 70 000 articles scientifiques et son incidence dans plus de 200 maladies.

The climate crisis is damaging the mental health of hundreds of millions of people around the world but the huge costs are hidden, scientists have warned. Heatwaves are increasing rates of suicide, extreme weather such as floods and wildfires are leaving victims traumatised, and loss of food security, homes and livelihoods is resulting in stress and depression. Anxiety about the future is also harming people’s mental health, especially the young, the scientists said in a report.

1.5 °C scenarios reported by the Intergovernmental Panel on Climate Change (IPCC) rely on combinations of controversial negative emissions and unprecedented technological change, while assuming continued growth in gross domestic product (GDP). Thus far, the integrated assessment modelling community and the IPCC have neglected to consider degrowth sce- narios, where economic output declines due to stringent climate mitigation. Hence, their potential to avoid reliance on negative emissions and speculative rates of technological change remains unexplored. As a first step to address this gap, this paper compares 1.5 °C degrowth scenarios with IPCC archetype scenarios, using a simplified quantitative repre- sentation of the fuel-energy-emissions nexus.

The number of countries announcing pledges to achieve net zero emissions over the coming decades continues to grow. But the pledges by governments to date – even if fully achieved – fall well short of what is required to bring global energy-related carbon dioxide emissions to net zero by 2050 and give the world an even chance of limiting the global temperature rise to 1.5 °C.

Scientists say ice equivalent to 1-2 metres of sea level rise is probably already doomed to melt

Where it’s no longer credible to deny climate change, the fossil fuel giant puts the focus on ‘risk’ and blame on consumers, in echo of tobacco industry PR, researchers find.
