A brief comment on the LA Times writeup.
Point 1: Notice that there has been a subtle or not no subtle change where some researchers are ascribing ancient warmings to the influence of ancient CO2 emissions. Keep in mind that no one has yet shown that the CO2 increase occurred before the warming. The warming could have occurred, and it caused the CO2 increase.
Point 2: Notice in recent times that large volcanic eruptions have caused global cooling. Why not also in the past?
