None of these events are noteworthy by themselves. Max they merit part of a sentence as an example of an ongoing trend.

E.g.
Serious human contribution to global warming which started in the early 20th century kept a pace and peaked in the early 21st century. Public opinion began to sour after an increased occurrence of climate disasters, such as tsunamis and forest fires.
Or:
The Russian successor state to the soviet union did make token efforts to reassert its power in Eastern Europe, such as the 2021 war in Ukraine. However those efforts ultimately proved futile and by 20xx all former Warsaw pact countries, excluding Russia itself, had joined the European union.
