The graph below is probably the most revealing of all the graphs used when discussing man-made global warming. John Christy presented it to a US Congressional hearing in 2017. The graph’s X axis shows years and the Y axis is global atmospheric temperature anomalys in degrees Centigrade. (“Anomaly” degrees, is the measurement of the change in temperature rather that the actual temperature. The actual temperature is somewhere around 15C. The exact temperature can be contentious. So the anomaly is usually charted.)
The red line is the “average of 102 IPCC CMIP-5 climate model runs. The man-made global warming theory doesn’t have one model. They had 102 models all churning out forecasts of the future global temperature. All with different assumptions of what will the future look like. All of them show rising temperature based primarily the amount of Carbon Dioxide (CO2) in the atmosphere. The forecast spread is all over the place based upon a number of other assumed forces. Christy averaged the forecasts and that is source of the red line.
Then Christy added the atmospheric temperatures that were MEASURED, by satellites and weather balloons.
So, stating the obvious, we have actual measured temperatures versus forecast temperatures. One can note that over the time, the separation between actual and forecast has gotten greater and appears that trend will continue
These forecast high temperatures are what propels the catastrophic man-made global forecasts of sky high sea levels, melting glaciers, mass migrations, mass extinction of species, terrifying severe weather, and deadly heat. The media revels in these forecast disasters and gives them top billing. But why would you believe this will be the Earth’s future? Surely if everyone knew this or have just learned it, why would they be persuaded to foist these irrational conclusions upon us?
You may be thinking that only one model would be necessary if they really could forecast average global temperatures.
