The Problem with 'Anthropogenic Global Warming'
By Ferdinand Bardamu

The mainstream "consensus" on anthropogenic global warming (AGW) says the atmospheric concentration of carbon dioxide (CO2) remained stable for millions of years, until the Industrial Revolution, when it went from 280 ppm in 1750 to 414.7 ppm in 2019.  Environmentalists blame this on man's consumption of fossil fuels, which has increased significantly since the early 1900s.

In support of the "consensus" view, climate change researchers write: "[T]he current CO2 concentration is unprecedented over the past 3 million years[.] ... [G]lobal temperature never exceeded the preindustrial value by more than 2°C during the Quaternary" (Willeit et al., 2019).  Environmentalists predict that, as anthropogenic CO2 rises, there will be more and more natural disasters, threatening the lives of millions of people around the world.  These include more frequent and severe hurricanes, widespread flooding, extreme heat waves, and prolonged drought.

1. Define the “correct” temperature range for the planet.

2. Define the “correct” humidity range for the planet.

3. Define the “correct” mean sea level for the planet.

4. Define the “correct” amount of precipitation for the planet.

5. Define the “correct” makeup of the atmosphere.

6. Define the “correct” amount of sea ice at the N/S poles.

7. Define/explain past glaciation and subsequent warming without any input from humans.

I read one pro-AGW piece the other week that tried to argue the warming period in Greenland which about one thousand years ago or more lasted for about four hundred years was restricted to just Greenland.
They know that how?
They couldn't have known that. We knew Greenland warmed up considerably because there were people there growing grapes and reporting what they did to other people back in mainland Denmark.  The Danes had to leave when the weather started getting much colder again.
In other areas of the Arctic there were simply roving bands of Eskimos/Inuits. They were too few and isolated to report what happened to anybody else.
 There is no record of populations on coastal areas of northern Europe being flooded/inundated during that time which botches their theory that if the Greenland ice sheet melts appreciably, it will flood many coastal towns/settlements. Well, the temps went up very high, but there is no record of northern European towns being flooded.

Not saying the conclusions were correct, but there are all sorts of physical evidence, like plant remains and ice cores, that help show what the climate was in a particular place.

Yes, I'm aware of that, but I just read an article by Anthony Watts of "Watts Up" where he showed that often plant remains didn't accurately depict the temps.
The Warmists would be a little more believable if they didn't try to fudge the stats or outright deny things.
A number of Warmists even denied the existence of the Medieval Warming Period (MWP) and the subsequent Little Ice Age.  Those periods existed in the last one thousand years, but people like Michael Mann denied their existence.
