Où serons-nous en 2055 ?
Climate inertia dictates that current atmospheric carbon levels lock in global temperatures until the 2050s, creating an immediate 25-year window to prevent irreversible catastrophe. Even in an idealized decarbonized 2055 scenario, midday temperatures will reach 50 degrees Celsius, forcing societies to adapt to extreme heat rather than return to historical norms. The critical decision lies in the next decade, where actions determine whether humanity faces an unsupportable future requiring life-or-death choices or achieves carbon neutrality to stabilize the climate. Failure to act within this timeframe will result in crossing lethal thresholds in certain regions, shifting the global paradigm from adaptation to survival.
L'histoire oubliée des Swahilis | Enquêtes archéologiques | ARTE
Archaeological excavations at Kilwa Kisiwani, a UNESCO World Heritage site spanning 44 hectares, reveal that Swahili stone cities built between the 10th and 15th centuries were constructed by indigenous East Africans rather than foreign civilizations. Despite colonial-era theories attributing these monumental structures to Greeks, Romans, or Persians due to their architectural complexity and imported Chinese and Iranian ceramics, modern research confirms local African agency in creating the largest Islamic building in sub-Saharan Africa during the medieval period. The site features unique coral masonry and architectural styles influenced by India, challenging historical narratives that denied African capacity for sophisticated urban development. Only about ten archaeologists currently work on the East African coast, leaving much of this history to be rediscovered through detailed structural analysis.
