A surprising surge in snowfall from 2021 to 2023 caused Antarctica to gain record amounts of ice, reversing 20 years of steady melting. This slowed global sea level rise by nearly 15% and sparked celebration among climate change skeptics. But scientists say the ice gain was likely a temporary result of rare weather, not a sign that global warming is over. Overall, Antarctica has still lost nearly 2 trillion tons of ice since 2002.
