Study Finds We’ll Lose Almost 40 Percent of Our Glacial Ice – State of the Planet

A recent study published in Science used glacier models to better understand the effect that each degree of global warming will have on worldwide glacier melt. The impacts of the warming the Earth has already experienced are yet to be fully realized, because glaciers have not reached equilibrium with the changing climate. The models provide […]
