Notice how all these are from the past, even a decade ago or more

Phillip,

Um, no I didn't notice that at all. One effort shows data from 2004, mainly due to 2004 being such a major year for the Muir Glacier. The rest are pretty recent. 20% are from 2020. 75% from the last 5 years.

Unless you meant that any remote sensing data is from the past, even if taken seconds ago.

Satellite data usually takes a little while to be made public due to processing requirements (e.g. ICESat-2 was launched in 2018, but some higher level products haven't been produced yet.) Then researchers need time to figure out what the data is actually showing.

What a shame that even when shown the data and research, some still think this is some hoax. I’m just glad I get to enjoy the planet before it’s completely destroyed. I feel sorry for future generations because it seems humanity won’t do anything until it’s too late. Nobody wants to change their habits, especially big corporations, to prevent a climate change disaster. By the time they realize it’s inevitable, it will be too late.

Also, regarding the images being a few years old, that’s obviously for security reasons. Satellite images made available to the public are never current for obvious reasons.

Most of these have nothing to do with global warming.

#1 Arctic ice cover has increased 50% since 2012. All these photos are examples of weather, not climate.

Arctic Sea-Ice Coverage Hits Record Low

"The area of the Arctic Ocean covered in ice increases during the winter and then shrinks during the summer, usually reaching the year’s low point in September. The minimum coverage for 2012 set a record low since at least 1979, when the first reliable satellite measurements began. These images compare the 1984 minimum, which was roughly equal to the average minimum extent for 1979–2000, with that of 2012, when the minimum was about half that. The 2013 minimum was larger, but continued the long-term downward trend of about 12 percent sea-ice loss per decade since the late 1970s, a decline that accelerated after 2007. The 2016 minimum was tied for the second-lowest on record. “At the rate we’re observing this decline,” said NASA scientist Joey Comiso, 'it’s very likely that the Arctic’s summer sea ice will completely disappear within this century.'"
