Joe Bastardi has been discussing this on his Saturday Summaries. Yes, it’s true with EL Nino to blame and it’s cyclical.
Things are going to turn around with a vengeance in the next season or two and the ice will be back.
Joe knows climate and weather. There is actually one way the satellite could be reading correct. If the main trend is colder, El Nino could be creating a false signal in the South. Ocean circulation slows. No heat getting to Arctic due to Bering Straits, but heat getting to South from El Nino surface heating. This might be the off switch for heating the deep Oceans. So Northern Hemisphere first goes into Ice Age, as it appears to be doing. Massive El Ninos, the source of the snow, keep the southern hemisphere lagging the Ice Age. As planet keeps cooling, El Ninos get weaker slowly. Then both hemispheres are in Ice Age. Just my 2 cents.
