I think the previous article is irrelevant: Why?

Because global Climate change IS REDUCING world populations no matter what people think worldwide!

Here is how world populations are being reduced:

Rain or drought interferes with regular plant growth especially fruits and grains and nuts and other vegetables.

This then creates Inflation along with Covid changes and the War in Ukraine. This all by itself reduces world populations by hundreds of millions more each year than before.

If people cannot afford to eat and cannot grow food by themselves on their own land because of droughts and floods then people starve all over the world.

It doesn't really matter whether the problem becomes food being too expensive to buy or whether the flooding or droughts prevent you from growing food on your lands. 

The result is exactly the same: Hundreds of millions of people starve to death worldwide more than usual.

This is what is actually happening worldwide now especially in 3rd world poorer nations.
