o sexto sentido dos glaciares

World is Getting Warmer:

This is from 1906. Most records show that glaciers have retreated since around 1820 right up to date. Those who want to blame retreating glaciers today on man-made CO2 have to first explain why the natural retreat from 1820 to about 1955 ended natural somehow at the exact moment that manmade Co2 took over.
