The lower troposphere is still warm from the El Nino.
But not as warm as it was in April 1998, when CO2 was much lower.
From April to November 1998, troposphere temperatures plummeted, as seen in this animation.
It appears we may be doing a repeat of 1998. But I am not a forecaster, and climate experts say that CO2 is the thermostat control knob. So temperatures can only go up.
