Yep, the whole Kurzgesagt channel is awesome and worth subscribing to.

Correct me if I'm wrong, but isn't the main concern with Kessler syndrome the debris which remain orbiting and which can potentially cause a chain reaction which takes down our entire satellite system? (See the video which starporcasa linked for my primary source of information too. ^_^' )
The stuff that end up losing velocity and going down to Earth will just burn up in the atmosphere and do nothing.

Yes, the bits that stay up in orbit are the problem with Kessler syndrome. But the bits that eventually fall down can still be a problem until they do. Which could be years if they are only just within the atmosphere.
Yes, the small bits that fall down are going to be harmless. But large bits can reach the ground and leave a crater, so they are a problem.

Would be typical for 2020, that it ruins space before the first clean up mission by the ESA is ready, in 2025.

We are monitoring a very high risk conjunction between two large defunct objects in LEO (thats low earth orbit).
Multiple data points show miss distance <25m and Pc between 1% and 20%. Combined mass of both objects is ~2,800kg.
Object 1: 19826
Object 2: 36123
TCA: Oct 16 00:56UTC
Event altitude: 991km
One satellite, one rocket stage. One (Cosmos 2004) is an old Russian communication/navigation satellite from the 1980s, and the other (CZ-4C R/B) is the upper stage of a Chinese Long March rocket that launched in 2009. Both of them are inactive and have been for a long time.
Projected landing site is most of new Zealand "if" the collission happens.
