Résumé des programmes suite au Débat Climat avec 7 candidat.es aux élections européennes et après consultation de leurs sites
Le débat a été modéré par Vinz Kanté, fondateur du média Limit Il s'est tenu à l'espace Talk C.E.C., chaussée de Wavre 143 à Ixelles où l'exposition Mers et Océans sera ouverte jusqu'au 7 juillet (https://talk-cec.com) Quelles sont les solutions proposées par nos politiques pour faire face à l'urgence climatique ? Après le mot de bienvenue de Talk C.E.C. et l'introduction de Rise for Climate, nous avons invité les candidats à présenter leur bilan du Pacte vert européen au cours du mandat 2019-2024 et leur programme climat pour le prochain mandat 2024-2029. Ensuite les collectifs Rise for Climate, Youth for Climate, Grands Parents pour le climat, Extinction Rebellion, et Mouvement d'Action Paysanne ont posé leurs questions ainsi que le public présent dans la salle.
Record-breaking temperatures were recorded across the globe in 2023. Without climate action, adverse climate-related health impacts are expected to worsen worldwide, affecting billions of people. Temperatures in Europe are warming at twice the rate of the global average, threatening the health of populations across the continent and leading to unnecessary loss of life. The Lancet Countdown in Europe was established in 2021, to assess the health profile of climate change aiming to stimulate European social and political will to implement rapid health-responsive climate mitigation and adaptation actions. In 2022, the collaboration published its indicator report, tracking progress on health and climate change via 33 indicators and across five domains.
Here, we show that the Last Glacial Maximum (LGM) provides a stronger constraint on equilibrium climate sensitivity (ECS), the global warming from increasing greenhouse gases, after accounting for temperature patterns. Feedbacks governing ECS depend on spatial patterns of surface temperature (“pattern effects”); hence, using the LGM to constrain future warming requires quantifying how temperature patterns produce different feedbacks during LGM cooling versus modern-day warming. Combining data assimilation reconstructions with atmospheric models, we show that the climate is more sensitive to LGM forcing because ice sheets amplify extratropical cooling where feedbacks are destabilizing. Accounting for LGM pattern effects yields a median modern-day ECS of 2.4°C, 66% range 1.7° to 3.5°C (1.4° to 5.0°C, 5 to 95%), from LGM evidence alone. Combining the LGM with other lines of evidence, the best estimate becomes 2.9°C, 66% range 2.4° to 3.5°C (2.1° to 4.1°C, 5 to 95%), substantially narrowing uncertainty compared t

Outgoing special rapporteur David Boyd says ‘there’s something wrong with our brains that we can’t understand how grave this is’
Oil and gas equipment intended to cut methane emissions is preventing scientists from accurately detecting greenhouse gases and pollutants, a satellite image investigation has revealed. Energy companies operating in countries such as the US, UK, Germany and Norway appear to have installed technology that could stop researchers from identifying methane, carbon dioxide emissions and pollutants at industrial facilities involved in the disposal of unprofitable natural gas, known in the industry as flaring.

Cost of environmental damage will be six times higher than price of limiting global heating to 2C, study finds
Global projections of macroeconomic climate-change damages typically consider impacts from average annual and national temperatures over long time horizons1–6. Here we use recent empirical findings from more than 1,600 regions worldwide over the past 40 years to project sub-national damages from temperature and precipitation, including daily variability and extremes7,8. Using an empirical approach that provides a robust lower bound on the persistence of impacts on economic growth, we find that the world economy is committed to an income reduction of 19% within the next 26 years independent of future emission choices (relative to a baseline without climate impacts, likely range of 11–29% accounting for physical climate and empirical uncertainty). These damages already outweigh the mitigation costs required to limit global warming to 2 °C by sixfold over this near-term time frame and thereafter diverge strongly dependent on emission choices. Committed damages arise predominantly through changes in average tempe
Decarbonization efforts and sustainability transformations represent highly contested socio-political projects. Yet, they often encounter various forms of depoliticization. This article illuminates how a grand socio-ecological challenge like the energy transition gets depoliticized by an unusual suspect, namely Germany's Green Party. Based on a qualitative content analysis of Green Party programs, party conventions, and additional documents published between 1980 and 2021, this article traces how the Green Party has depoliticized the energy transition over time, emphasizing a shift from radical societal change to ecological modernization. The changing stance of the German Greens on the country's energy transition reflects more profound changes of a future society the party collectively envisions through their energy and climate change agenda. These changes result from a struggle between moderates advocating incremental political reforms and radicals aiming for more fundamental and systemic societal change.

Dr Sarah Benn has long been concerned about the climate crisis, diligently recycling until she was “blue in the face”. But the rise of the climate activist group Extinction Rebellion in 2019 inspired her and her husband to go further. “We thought: well, if we don’t do it then who else is going to?”

Evidence shows a continuing increase in the frequency and severity of global heatwaves1,2, raising concerns about the future impacts of climate change and the associated socioeconomic costs3,4. Here we develop a disaster footprint analytical framework by integrating climate, epidemiological and hybrid input–output and computable general equilibrium global trade models to estimate the midcentury socioeconomic impacts of heat stress. We consider health costs related to heat exposure, the value of heat-induced labour productivity loss and indirect losses due to economic disruptions cascading through supply chains. Here we show that the global annual incremental gross domestic product loss increases exponentially from 0.03 ± 0.01 (SSP 245)–0.05 ± 0.03 (SSP 585) percentage points during 2030–2040 to 0.05 ± 0.01–0.15 ± 0.04 percentage points during 2050–2060. By 2060, the expected global economic losses reach a total of 0.6–4.6% with losses attributed to health loss (37–45%), labour productivity loss (18–37%) and i

Dangers of wildfires, extreme weather and other factors outgrowing preparedness, European Environment Agency says
A new study led by researchers at the University of Oxford has used the fossil record to better understand what factors make animals more vulnerable to extinction from climate change. The results, published today in the journal Science, could help to identify species most at risk today from human-driven climate change.
