And remember, the satellite data are one small part of a vast amount of data that overwhelmingly show our planet is warming up: retreating glaciers, huge amounts of ice melting at both poles, the «death spiral» of arctic ice every year at the summer minimum over time, earlier annual starts of warm weather and later starts of cold weather, warming oceans, rising sea levels, ocean acidification, more extreme weather, changing weather patterns overall, earlier snow melts, and lower snow cover in the spring...

Sorry, wasn't there for the last ice age, or even the LIA; don't know anyone who was, personally, and have no record of thermometers or other reliable measuring apparatus in place at the time; no video, no pictures, no sound, no data recording of any kind, merely the proxies in the geological and ice records, and they don't exactly give the sort of information I'd call a credible basis for concluding what exactly resulted in each ice age starting when it did.

There are the famous data sets: the Vostok ice core drilled in the 1970s that looks back about 400,000 years, the Keeling curve started in 1958, data from satellites that watch sea ice retreat starting around 1979.

This is such an utter non-story — amounting to no more than «NSIDC have another year's worth of winter Arctic ice data» — that the only reason we can see for the BBC giving it the time of day is to guard against the possibility that people start filling their pretty heads with silly notions that the extent of summer Arctic sea ice varies from year to year, and that while it seems to have been reducing a bit over the last few decades, it hardly follows that it spells the end of the world as we know it.

I find it interesting and perhaps somewhat troubling that pre-1979 satellite derived sea ice data was good enough to include in the first IPCC report in 1990, but for some reason not included in the current satellite derived sea ice data which all seems to start in 1979:

Greenland ice cores indicate that the start of the instrumented data (thermometers) coincides with a cold period in the northern hemisphere and that at the site of a well - studied ice core (Global Cooling - Doomsday Called Off), the temperature in the mid 1800s was the coldest in 8,000 years.
