What do you have planned for next week? And next year? Have you ever thought about what you will be doing in 250 million years? Probably not. But you might be wondering what the Earth will look like then. 250 million years is enough for its face to change as well. So many years ago, a meteorite flew to our planet, wiped out 90 percent of all living things and left an imprint in the form of a crater in Antarctica. But that is the past.
Christopher Scotese, profesor z oddelka Earth and Planetary Sciences na ameriški univerzi Northwestern, se ukvarja s prihodnostjo.
Ne s kakršnokoli, ampak z Zemljino. Na podlagi teorije o tektonskih premikih in globalnega segrevanja je napravil različne animirane zemljevide, ki prikazujejo Zemljo čez 250 milijonov let. Z zemljevida lahko razberemo, da bo Pangea Ultima, kot je Scotese naš planet poimenoval, zaradi subdukcije oceanskega dna v severnem in južnem Atlantiku pod Severno oziroma Južno Ameriko ena sama ogromna celina, sredi katere bo ujet majhen ocean. Enaka usoda naj bi dočakala Indijski ocean. Združili naj bi se obe Ameriki in Afrika, Patagonija naj bi se dotikala Indonezije. Antarktika se bo spet preselila na južni pol, Tihi ocean pa obsega površino vseh celih današnjega časa.
