Antarctica’s Thwaites Glacier melting faster than thought, could double sea-level contribution

One of the world’s largest glaciers is melting much faster than previously understood and could contribute about twice as much to global sea-level rise by the end of the century as earlier projections suggested.

Heating climate could increase risk of Arctic ‘virus spillover’

A warming climate could bring viruses in the Arctic into contact with new environments and hosts, increasing the risk of “viral spillover”, according to newly published research.

Πώς η κλιματική αλλαγή θα μπορούσε να επηρεάσει τα ηφαίστεια

Θα μπορούσε η κλιματική αλλαγή να επηρεάσει την ηφαιστειακή δραστηριότητα; Αυτό υποστηρίζουν Αμερικανικοί και Γερμανοί ερευνητές σε έκθεσή τους, η οποία δημοσιεύεται στην επιθεώρηση Geology.
Μέχρι σήμερα ήταν γνωστό ότι τα ηφαιστειακά φαινόμενα μπορούν να έχουν τεράστιες επιπτώσεις για το κλίμα και τον πλανήτη γενικότερα. Έχει, για παράδειγμα, διατυπωθεί η θεωρία ότι ο μεγάλος αφανισμός στο τέλος της Πέρμιας Περιόδου προκλήθηκε, μεταξύ άλλων, από ηφαιστειακές εκρήξεις που μείωσαν τη θερμοκρασία του πλανήτη, δηλητηριάζοντας την ατμόσφαιρα και τις θάλασσες.
