While that's true, it's pretty relevant if you're trying to detect or measure human-caused climate changes. And particularly with respect to changes in both population growth and the effects of the industrial revolution. The planet went from having around 350 million people in 1000AD, to over 8 billion people now. We went from powering things with human and animal muscles and heating things with effectively carbon-neutral woodfires with only decades or centuries of captured carbon, to burning coal and oil releasing millions or hundreds of millions of years worth of captured carbon into the atmosphere.

Okay, but have you looked at the chart? Because it's very clearly changing in the past century or so.

"climate change is a hoax."

"Climate change has no scientific evidence"

"Climate change is only peddled by quack researchers"

"Climate change isn't widely accepted yet"

"Climate change cannot happen as fast as research is predicting" <---- you are here

"Snow rarely happens around town anymore"

"I hope my children can vacation to Alaska to ski"

Uh oh, Joe Rogan school of science graduate spotted. Experts in the field are very concerned about the rate of change. Please stop comparing magnitude of change across different timespans.
