LYRICS
The forces of nature
Continue to grow
Divorce from mature
What’s in you will show
The choices we made
Continue to blow
Voices that throw shade
Miss what’s in the know
Now that we’ve dared
The velocity squared
Tossed to and fro
The undertow
Of the overflow
The drag force… of course!
Intensity density
Continues to grow
Sensitivity of humanity
Is still a no-show
The choices we made
Continue to blow
Voices that throw shade
Miss what’s in the know
Now that we’ve dared
The velocity squared
Tossed to and fro
The undertow
Of the overflow
The drag force… of course!
The destiny of energy
Is quid pro quo
As humanity gets angry
At the ill we show
The choices we made
Continue to blow
Voices that throw shade
Miss what’s in the know
Now that we’ve dared
The velocity squared
Tossed to and fro
The undertow
Of the overflow
The drag force… of course!

Technically Speaking, It’s Not the Momentum That Kills You
It’s not the fall that kills you; it’s the sudden stop at the end.
Technically speaking it is the impact from the momentum that causes damage and deaths. Global warming causes an increase in mass and/or velocity (momentum) of things that are mass flow driven by heat, like wind and flood.
The burning of fossil fuels and other human released emissions have impacted momentum’s impact. A warmer atmosphere can hold more moisture. Warmer air allows for the creation of more massive raindrops. Warmer ocean temperatures create stronger hurricanes. Hail and tornadoes form in strong thunderstorm clouds with intense updrafts, high liquid-water content, and large water droplets.
Sidd added: It’s worse than that. Wind and water flow forces scale as the square of velocity, so as flow speeds increase (say due to more intense heating or heavier rain) the damage scales as the square of the velocity.
About “square of the velocity”, I asked Sidd: is this Bernoulli’s Equation?
Sidd replied:
look at Wikipedia: Drag (Physics)
you will see that force is proportional to density times square of velocity (v^2)
So a twenty mile an hour wind exerts four times as much force as a ten mile an hour wind. And a forty mile an hour wind exerts sixteen times as much force as a ten mile an hour wind. A wind of fifty miles an hour exerts twenty five times and a wind of sixty miles an hour exerts thirty six times as much force as one of ten miles an hour. Then you have the density term. Water is about eight hundred times denser than air, So the force exerted by a ten mile an hour flow of water is eight hundred times that of a ten mile an hour wind. So as flow velocities go up due to climate change, force and damage scale as square of the velocities. What is not clear is how much these velocities increase with climate change. But in a sense we are seeing this already as, for example, flood and sewage systems succumb and hillsides fall down, and so on. — from “Climate Change: The Equation” / Brouse and Mukherjee (2023)
