Re: “political tools”.

At least two meanings of “tools” are appropriate in this context.

People moving to where there is water isn’t exactly news. It pretty much defines history.

Trying to do something about climate change does more damage than climate change. The reality is that we only know the climate is changing and that is because it can’t not change. We don’t have any idea whether it is warming or cooling and we don’t really know what the cause is either way. All we can do is theorize about carbon dioxide because it is pretty much guaranteed that there is more CO2 in the atmosphere since humans started burning coal and petroleum. But cutting carbon dioxide is only done by reducing economic activity.

The CRISIS is entirely political in origin, has no scientific basis, and the jackasses and jillasses who drive the agenda don't care whether anyone else lives or dies, as long as they are the ones in charge.

A powerful tropical volcanic eruption around 266 CE, which in the following year brought a below-average flood of the Nile, presumably also played a role. Major eruptions are known from sulfuric acid deposits in ice cores from Greenland and Antarctica, and can be dated to within three years. Particles hurled up into the stratosphere lead to a cooling of the climate, disrupting the local monsoon system.(your ref)

Followed by the 535 eruption of Krakatoa. Summer temperatures in 536 fell by as much as 2.5 degrees Celsius (4.5 degrees Fahrenheit) below normal in Europe.

I was constrained by the word count, also, I don't have much use for volcanological "explanations" for climate. That said, climate is 100 percent natural 100 percent of the time.

"However much longer the Modern Warm Period lasts, we should be glad we live in it."

My thoughts exactly.

Climate change never sleeps.

4.5 billion years old and still going strong.
