Aujourd’hui, nous recevons à nouveau Laurent Testot, journaliste spécialisé en Histoire Globale, avec qui nous allons retracer l’histoire des villes et discuter de l’avenir de celles-ci : * A quoi ressemblaient les cités d’hier ? * Quelles sont les impasses de nos métropoles actuelles ? * Et à quoi doit-on s’attendre pour les villes de demain ?

Thousands of rallies are expected across the U.S. on Saturday as part of the latest “No Kings” protest against the policies of President Donald Trump and his administration. Organizers said more than 3,200 events are planned in all 50 states for what they hope could be the largest single-day nonviolent protest in U.S. history. The two previous No Kings events attracted millions of participants.

Cutting-edge materials and thoughtful urban planning can help cities beat the negative heating effects of climate change.

Aujourd’hui, j’ai le plaisir d’accueillir Laurent Testot, journaliste scientifique et spécialiste d’histoire globale.

For the last 80 years, Thwaites has been losing more water through melting than it’s been gaining in snow.Half a metre of sea-level rise would submerge large parts of Asia’s coastal cities including Manila and Bangkok, as well as sizeable chunks of the Netherlands and the east of England. It’s also half of the sea-level rise needed to begin flooding Manhattan.

Heat caused 2,300 deaths across 12 cities, of which 1,500 were down to climate crisis, scientists say

Aujourd’hui nous allons parler de Géoingénierie. Ce sujet, qui n'était autrefois vu que comme un projet d'apprentis sorciers, est aujourd'hui présent dans tous les plans climatiques gouvernementaux. Mais comment la géo-ingénierie s’est infiltrée dans les sphères politiques et que cache réellement ce concept ? Quels sont concrètement les projets de géoingénierie, sont-ils vraiment viables, et à quels risques nous exposent-ils ? Entre fuite en avant, technosolutionnisme, et enjeux géopolitiques, quelles intentions motivent réellement la géoingénierie ? Pour parler de ces sujets, j’ai le plaisir d'accueillir Marine De Guglielmo Weber. Marine est docteure en sciences de l'information et de la communication, chercheuse au sein de l'Institut de recherche stratégique de l'école militaire, directrice scientifique de l'Observatoire Défense & Climat et auteur de différents ouvrages dont Le Grand Retournement et La Géopolitique des Nuages.

For around 2,000 years, global sea levels varied little. That changed in the 20th century. They started rising and have not stopped since — and the pace is accelerating. Scientists are scrambling to understand what this means for the future just as President Trump strips back agencies tasked with monitoring the oceans.

Previous health impact assessments of temperature-related mortality in Europe indicated that the mortality burden attributable to cold is much larger than for heat. Questions remain as to whether climate change can result in a net decrease in temperature-related mortality. In this study, we estimated how climate change could affect future heat-related and cold-related mortality in 854 European urban areas, under several climate, demographic and adaptation scenarios. We showed that, with no adaptation to heat, the increase in heat-related deaths consistently exceeds any decrease in cold-related deaths across all considered scenarios in Europe. Under the lowest mitigation and adaptation scenario (SSP3-7.0), we estimate a net death burden due to climate change increasing by 49.9% and cumulating 2,345,410 (95% confidence interval = 327,603 to 4,775,853) climate change-related deaths between 2015 and 2099. This net effect would remain positive even under high adaptation scenarios, whereby a risk attenuation of 50%

For those trying to pay attention in our post-truth, post fact-checking brave new world that has such misinformation systems in it, Dr. Rees is a source to consider. The link: Climate Change, Overshoot and the Demise of Large Cities: Why large cities will need to contract or be abandoned altogether
