from what is reported already happening, expect massive (hundreds of millions) climate refugees to really get going within the next five to ten years.

What data does your suspicion derive from?

Because historians work on different time scales. Stuff from only a few decades ago is still politics, not history.

That's quite the non-sequitur. What relationship are you implying between this supposition and the scientific facts of climate change? Would your argument change if it were astronomers telling you an asteroid would hit in 5 years?

I was replying to > In a few decades, historians will be able to look back

Historians don't look back only a few decades. That's still politics. Sorry if that wasn't clear.

My mistake, I thought we were still discussing climate change, not dropping into definitional pedantry.

Since we're into definitional pedantry, you're incorrect anyway: https://en.wikipedia.org/wiki/Contemporary_history

All signs point to you being wrong.

Good riddance
