Der CO<sub>2</sub>-Gehalt der Atmosphäre wird 2024 weiter steigen, so dass die vom IPCC erarbeiteten Pfade, um das 1,5°-Ziel einzuhalten, nicht mehr eingehalten werden können. Das ergibt sich aus einer Studie des britischen Met Office, die sich auf die Daten des Mauna Loa-Observatoriums in Hawai stützt. (Die obere Grenze der Unsicherheitsbereiche dieser Pfade ist erreicht, selbst wenn der El-Niño-Einfluss abgezogen wird. Ein Einhalten der Pfade würde ein sofortiges Absinken des CO<sub>2</sub>-Gehalts erfordern.) https://www.liberation.fr/environnement/climat-les-concentrations-de-co2-cette-annee-menacent-la-limite-de-15c-daugmentation-globale-des-temperatures-20240119_6JIALPQDBNADFGNHS4MVDXR5QA/?redirected=1

The prevailing hypothesis has been that volcanoes like these two in Hawaii are chemical fingerprints of the Earth’s composition at the deep mantle, just at the border of its core.

Mauna Loa, the biggest volcano on Earth — and one of the most active — covers half the Island of Hawaii. Just 35 miles to the northeast, Mauna Kea, known to native Hawaiians as Mauna a Wakea, rises nearly 14,000 feet above sea level. To them it represents a spiritual connection between our planet and the heavens above.These volcanoes, which have beguiled millions of tourists visiting the Hawaiian islands, have also plagued scientists with a long-running mystery: If they are so close together, how did they develop in two parallel tracks along the Hawaiian-Emperor chain formed over the same hot spot in the Pacific Ocean — and why are their chemical compositions so different?
