Arctic sea ice has been consistently shrinking since at least 1980. So have the Greenland and West Antarctic ice sheets. The East Antarctic ice sheet has by contrast been constantly growing since records began, which is probably where you got your factoid from. But this is due to local phenomena, such as the Antarctic ozone hole, increasing westerly wind strength and increasing snowfall. East Antarctica is one of the few regions which seems to have escaped the effects of climate change (so far).
There's almost no doubt that the world is warming overall due to human activity. The fossil fuel industry doesn't like this, so they put out propaganda to counter facts. Do your own research :).
Adding to this, M2 U2 M2 swaps the 2 opposite edges in the top layer as well as the 2 opposite cross edges. So, if you mess up your cross, you can do the entirety of F2L and OLL, then do M2 U2 M2 before PLL, also swapping 2 top edges in such a way that you "force" a good PLL (IIRC you can turn a G perm into a J perm by doing this).
It looks like a lot more people left Reddit than joined Lemmy or the other Reddit alternatives. I reckon most people who left didn't actually seek out an alternative and are just spending more time on Facebook/Tiktok/forum sites etc. Or they might be being productive with the time that they would've otherwise spent on Reddit lol.
As a uni student I do both. I generally type notes during lectures and live meetings, and handwrite notes for prerecorded videos and other general study.
I still handwrite because my exams are going to be handwritten and I don't want to lose my ability to handwrite fast lol.
You can also doodle/draw diagrams when you handwrite. It's harder to do that on a phone/computer.
I still use pen and paper because it just feels better than handwriting on a screen.
Oh egads, my toilet is ruined!
