Coincidence? There was no man made CO2 (or very little) back then.


How do you know when the El Nino peaked?


We know ENSO peaked back then because if you read the articles in this
thread, they say so. A scientist, with no agenda save science, says
so. ENSO has a cycle, and the last cycle peaked around 800AD+, when
there was a warming period.

Ergo, man-made GHGs may not be responsible for ENSO.

Ergo, ENSO may be responsible for GW.

Ergo, further research is needed on the AGW = GW hypothesis.
