"The history of temperature change over time is related to
the shape of the continents, the shape of the sea floor,
the pulling apart of the crust, the stitching back together
of the crust, the opening and closing of sea ways, changes
in the Earth's orbit, changes in solar energy, supernoval
eruptions, comet dust, impacts by comets and asteroids,
volcanic activity, bacteria, soil formation, sedimentation,
ocean currents, and the chemistry of air. If we humans, in
a fit of ego, think we can change these normal planetary
processes, then we need stronger medication."
