Top Pro & Con Arguments
Glaciers have been growing and receding for thousands of years due to natural causes, not human activity.
The IPCC predicted that Himalayan glaciers would likely melt away by 2035, a prediction they disavowed in 2010.  In 2014 a study of study of 2,181 Himalayan glaciers from 2000-2011 showed that 86.6% of the glaciers were not receding. 
A study of ice cores published in Nature Geoscience said the current melting of glaciers in Western Antarctica was due to “atmospheric circulation changes” that have “caused rapid warming over the West Antarctic Ice Sheet” and cannot be directly attributed to human caused climate change.  According to one of the study authors, “[i]f we could look back at this region of Antarctica in the 1940s and 1830s, we would find that the regional climate would look a lot like it does today, and I think we also would find the glaciers retreating much as they are today.”  According to Christian Schlüchter, Professor of Geology at the University of Bern, the retreat of glaciers in the Alps began in the mid-19th century, before large amounts of human caused CO2 had entered the atmosphere.
