by Evan Lim, Columbia University Earth Institute Two new studies suggest that recent estimates of global ice melt are conservative. In other words, ice is melting much more rapidly than experts thought. As a result, sea levels are rising faster as well. The first study combines various observations from satellites, on-the-ground measurements, and model-based estimates to create a clearer picture of the state of Earth’s ice between 1994 and 2017. Essentially, it captures a global tally of change in ice mass over that time period. The resulting measurements of ice loss and sea level rise fall in the upper range of scenarios forecast by the Intergovernmental Panel on Climate Change (IPCC), a body within the United Nations meant to provide objective science related to climate change. The IPCC’s scenarios were laid out in their 2019 special report on oceans and the cryosphere, itself a recent overview of assessment work.
