From the ice-locked edges of the world, a quiet but profound signal is emerging: grasses now grow where none grew before, and fire has touched islands that once knew only cold. Australian scientists at Monash University have documented invasive vegetation spreading across Antarctic landscapes, a consequence of human-driven warming that is reshaping one of Earth's last stable frontiers. The findings arrive as a reminder that the planet's most remote places are not insulated from our choices — and that the distance between inaction and consequence is shrinking faster than the ice itself.
