Little Ice Age Commentary climateprogress.org A detailed look at the Little Ice Age October 7, 2010 Here’s a key point that the media has failed to explain and the the anti-science disinformers refuse to accept: The Earth’s overall temperature does not change randomly on a decadal scale — it changes when it is driven to do so by an external forcing. The Little Ice Age is a case in point, as Skeptical Science explains in this repost: The argument that we’re simply “coming out of the Little Ice Age (LIA)” makes one of two assumptions: The planet oscillates around some natural equilibrium temperature such that after it cools, it must warm to return to this temperature, and vice-versa. Whatever caused the LIA cooling has reversed phase and is now causing global warming. The first assumption demonstrates a lack of understanding regarding what causes planetary temperature changes. The second does not hold up under scrutiny of the empirical data.
