While there was a lot of FUD in the media, there were also a lot of scenarios that were actually possible but were averted due to a LOT of work and attention ahead of time. It should be looked at, IMO, as a success of communication, warnings, and a lot of effort that nothing of major significance happened.
Yes, Y2K is a success story, similar to the alert and response related to ozone layer and CFCs.
Dissimilar to the global climate catastrophe, unfortunately.

"Tragically, we are failing to avoid serious impacts"
"We have now brought the planet into climatic conditions never witnessed by us or our prehistoric relatives within our genus, Homo"
"Despite six IPCC reports, 28 COP meetings, hundreds of other reports, and tens of thousands of scientific papers, the world has made only very minor headway on climate change"
"projections paint a bleak picture of the future, with many scientists envisioning widespread famines, conflicts, mass migration, and increasing extreme weather that will surpass anything witnessed thus far, posing catastrophic consequences for both humanity and the biosphere"
