Global sea ice fell to a record low in February, scientists have said, a symptom of an atmosphere fouled by planet-heating pollutants. From a report: The combined area of ice around the north and south poles hit a new daily minimum in early February and stayed below the previous record for the rest of the month, the EU's Copernicus Climate Change Service (C3S) said on Thursday. "One of the consequences of a warmer world is melting sea ice," said the C3S deputy director, Samantha Burgess. "The record or near-record low sea ice cover at both poles has pushed global sea ice cover to an all-time minimum."

The agency found the area of sea ice hit its lowest monthly level for February in the Arctic, at 8% below average, and its fourth-lowest monthly level for February in the Antarctic, at 26% below average. Its satellite observations stretch back to the late 1970s and its historical observations to the middle of the 20th century. Scientists had already observed an extreme heat anomaly in the north pole at the start of February, which caused temperatures to soar more than 20C above average and cross the threshold for ice to melt. They described the latest broken record as "particularly worrying" because ice reflects sunlight and cools the planet.
