In September 2022 (1-6 September), a substantial ice melting event was recorded atop the Greenland ice sheet. Scientists warned about the implications of this extensive melting event. At its peak on July 18, surface melting spanned 688,000 square kilometers (266,000 square miles) of the ice sheet. A late-season warm spell (September 1–6 2022, with its peak on September 3), caused the melting of 592,000 square kilometers of the ice sheet.
