What does it mean that (once rare) atmospheric rivers and bomb cyclones are becoming more frequent?

[Scott]

 

Atmospheric rivers and bomb cyclones are becoming increasingly frequent and intense parts of the North American meteorological landscape. Atmospheric rivers can cause enormous flooding events across the country. Bomb cyclones can combine hurricane conditions with Arctic cold to produce enormous personal risk from exposure to potentially deadly cold. Sometimes they occur at the same place at the same time. When that happens, as in December of 2022, they complement each other — arguably producing combined impacts that are greater than the sum of their singular impacts taken one at a time in isolation.

It means that we have to take seriously the scientific based research showing that man made climate change is approaching a tipping point.

More bad weather frequent flooding much higher insurance rates more famine on (our)earth time to take things seriously and make changes

Come now, didn't you read the article?

 

It's there in black and white, it clearly states "The undeniable increase in frequency and intensity of one or the other or both of these extreme meteorological extremes..."

 

Given the article includes 21 links in the text, it's obvious it was simply an oversight that there is no link attached to "undeniable"
