Greenland and Antarctica have lost about 11.3 trillion tonnes of ice since the 1970s, according to a new study, contributing to global sea-level rise. The study estimates the ice loss has raised worldwide sea levels by more than 1.1 inches (about 3 cm).
The reporting focuses on the scale and timeframe of the change, attributing the sea-level impact to long-term ice mass loss across both regions. Both sources describe the figures consistently: the cumulative ice loss since the 1970s and the corresponding sea-level contribution. They do not provide additional methodological details in the excerpts provided, nor do they describe differences in satellite or modeling approaches.
Overall, the accounts align on the central findings—magnitude of ice loss and estimated sea-level rise—and present them as results of a single, newly published analysis, without highlighting contrasting interpretations or data disputes in the included text.
