How we got climate change started early in Europe

Turns out that soot from the early industrial revolution has been tabbed as one of the main reasons (if not the main reason) that glaciers in the Alps started melting and receding in the 1850s. This was prior to the generally-accepted end of the Little Ice Age, and also prior to a significant increase in greenhouse gas emissions and greenhouse gas atmospheric concentrations, which has since, over decades, led to increased melting, which is likely the major cause of glacier shrinkage now. 

Which all goes to show that the climate is a multi-faceted system, and changing any factors can affect other factors downstream. In this case, the glacial meltwater streams downstream.

Pollution melted Alps' glaciers, not rising temperatures
