Ok, I live in Alberta, Canada. I grew up in the woods of Northern Alberta. We can get week long bouts of -40°C/F and I have NEVER seen or heard of exploding trees in the area. Are American trees just weak, or is this fake?
Trees further south have different conditions.
When we get cold snaps before 15f in the mid Atlantic tree sap that doesn’t usually freeze will freeze and limbs will pop. I’ve never seen a tree explode but I’ve definitely heard trees blowing limb and bits of themselves in the woods. Wind exacerbates the phenomenon
I’m going to guess it has to do with how quickly the temperature change occurs, or other environmental factors. It seems to be a somewhat rare occurrence, even in places where it gets very cold
In Alberta a chinook can make the temp go from -20 to 20 in a matter of hours, the same backwards.
Huh TIL
The maximum daily temperature anomaly associated with the wind ranges from +13°C in the northwest to +25°C in the southeast. The temperature rise at the onset of the event is abrupt and steep; an increase of 27°C in 2 minutes has been observed.
They also create clippers on their way to states, hence the term Alberta Clipper.
Does wind chill make water freeze faster?
The helicopter?
With enough flamethrowers, or an atom bomb, I’m sure the same could be attained.
It was raining here two weeks ago. Temperatures were in the 20-30s earlier this week. It’s being far below freezing AND recent warm weather that’s the danger.

It isn’t common, and explode is an exaggeration for what I have seen - just cracked bark (though the crack was probably abrupt and loud). Montana gets some every now and again, so I am guessing at least some parts of Alberta do too. Nobody has made a big deal about it in the past outside of folks interested in trees. This is some weird media hype.
