Studies show that measurable anthropogenic climate change began with the deforestation of Europe in the Middle Ages.

Why should the forests of Europe be so powerful as to change the world's climate? Isn't that just one of those silly "blame everything bad on white people" tropes? 12% of the world's population on 6.8% of the world's land covering 2% of the surface of the planet and it was the slow and primitive manual labor tree felling that started climate change. That sir, is absurd.

It has, but never this quickly without a supervolcano or asteroid in the mix.

Surely you don't claim this is a fact base on science.

What is the actual mechanism by which humans control the climate? Is it number of trees? Are you aware of the fact that there are more trees now then before the Middle Ages?

Like I said, the change due to the deforestation of Europe was tiny and not noticable by human beings without instruments. But it was measurable with modern instruments. Why Europe? Just because it was the first continent to be deforested. And losing 1% of the world's trees does change the ratio of oxygen to carbon dioxide in a measurable way.

What is the actual mechanism by which humans control the climate?

Our activities change the ratio of oxygen to carbon dioxide in the atmosphere.

Are you aware that before the ice age started the concentration of co2 was 4k ppm and today it is only 400 ppm?

How did we enter into massive global cooling during a time when co2 was 100x higher?

During the last ice age, the concentration of atmospheric CO2 was, on average, 180 ppm. Today it's 423ppm.

The last time it was about 4,000 ppm (which is 10x higher, not 100x higher) was during the Ordovician. That was 500 million years ago, and the surface temperature at that point was an average of 120 degrees Fahrenheit, compared to 59 degrees today.
