"they've been wrong since forever."

Forever began in 1896.

Arrhenius developed a table showing temperature increases/decreases across the latitudes for the following ratios of future-to-present carbon dioxide levels: 0.67, 1.5, 2.0, 2.5, and 3.0 (Table VII, op. cit.). To quote from this table, a doubling of the amount of carbon dioxide would produce a temperature increase ranging from a minimum of 4.95oC near the Equator (latitudinal range 0-10o N, or 0-10o S), to a maximum of 6.05oC in the Arctic (latitudinal range 60o-70o N). This latter accomplishment is remarkable since more than one-hundred years later the issue is still the subject of much debate.

In 1908, he wrote
On the other hand, any doubling of the percentage of carbon dioxide in the air would raise the temperature of the earth's surface by 4°;

The equilibrium climate sensitivity (ECS) refers to the equilibrium change in global mean near-surface air temperature that would result from a sustained doubling of the atmospheric (equivalent) carbon dioxide concentration (?Tx2)
As estimated by the IPCC Fifth Assessment Report (AR5) "there is high confidence that ECS is extremely unlikely less than 1°C and medium confidence that the ECS is likely between 1.5°C and 4.5°C and very unlikely greater than 6°C." [4]

We spiked at 1.51 last Feb, with CO2 up about 41%. If this is linear, that would put the sensitivity at about 3.75 degrees.

Arrhenius really had it together.
