Two interesting graphs from my son's science fair paper

Note that it has warmed every season in every hemisphere,
but there was more warming in the winter than the summer.
In his paper of 1896, "On the Influence of Carbonic Acid
in the Air upon the Temperature of the Ground," Svante
Arrhenius correctly predicted this result. He said,
"The influence is in general greater in the winter
than in the summer, [ . . . ]"
Does 21st century science still agree with Arrhenius
that this is due to CO2 and H20 saturating the same
portions of the infra-red spectrum and diminishing
each other's effect?
