2022
Nous émettons du CO2. Les forêts brûlent. Les glaces fondent. La Terre se réchauffe. Inexorablement. Et de plus en plus de gros titres nous préviennent. Le point de non-retour est proche. Même si certains chercheurs remarquent que le concept n\'a peut-être que peu de sens en écologie. Chaque détérioration apportant son lot de conséquences.

Changement climatique, érosion de la biodiversité, évolution démographique, pollution atmosphérique, détérioration des sols, catastrophes naturelles, accidents industriels, crises sanitaires, mobilisations sociales… Voici le premier atlas réunissant l'ensemble des données sur la crise écologique de notre temps.
Et si, lorsque nous préparons nos vacances, nous divisions par deux la distance que l’on parcourra ? Pourquoi sommes-nous si immobiles face à l'urgence climatique?
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.

The framing of climate change, in particular, as something that wouldn’t be an issue if “we” had all just made better consumer choices has been persistent and effective. Every Earth Day, we’re bombarded with tips about how to minimize our personal carbon footprints; meanwhile, it’s 2021 and the GOP is still suggesting tree-planting as climate policy.
