    By 2100, Greenland will be losing ice at its fastest rate in 12,000 years

    The rate of loss of Greenland’s ice will soar over the next century even with greatly reduced greenhouse gas emissions.

    Global warming may lead to practically irreversible Antarctic melting

    Simulations suggest that even if the Paris climate goals are met, melting Antarctica ice will still cause sea levels to rise by more than 2 meters.

    Climate

    Bering Sea winter ice shrank to its lowest level in 5,500 years in 2018

    Peat cores that record five millennia of climate shifts in the Arctic region suggest recent ice loss is linked to rising carbon dioxide levels.

    Earth’s building blocks may have had far more water than previously thought

    Space rocks and dust from the inner solar system could have delivered enough water to account for all the H2O in the planet’s mantle.
