Glaciers’ Retreat Not From CO₂

Retreating glaciers are often pointed to as “proof” of human-induced global warming by those predicting climate catastrophe.

And they are partially correct. The planet IS warming and glaciers ARE retreating, but the beneficial warmth began more than 300 years ago. That was long before any temperature increases could have been caused by emissions of carbon dioxide. The chart here is a compilation of 169 glaciers worldwide (Oerlemans 2005).

Note that, although our current warming trend began in the late 1600s, the glacial retreat wasn’t initiated until the early 1800s. That is because it took 100-plus years for the warming to cause more summer melting than winter accumulation.

A highlight of many Alaskan cruises, Glacier Bay is often pointed to as a warning of our “sins of emission.” However, retreat of this glacier began in the late 1700s and had retreated some 50 miles before significant additions of CO₂ in the mid-20th century. There have been only about 10 miles of retreat since (Seramur 2001).

Glacial facts simply do not support the theory that CO₂ is the primary cause of modern warming.

Fun Fact: Famine Is Declining … A LOT

Modest warming, more CO₂ and use of nitrogen fertilizer (manufactured from fossil fuels) are boosting food production and driving a significant decline in famine.
