Tony Heller argues that US thermometer data shows a century of cooling and that NOAA adjusts the record to produce a warming trend.

Adam Neely explains that Warner Music claimed his video, which defended their copyright in a lawsuit, over a work whose copyright they had lost. He calls it an ironic and absurd claim, and the claim was later released.

Linus Tech Tips water-cools a 2020 MacBook Air, tearing it down and showing the cooling design along the way. The video shows the gap between the CPU lid and die and how little the stock heatsink does.
