Climate experts claim that melting glaciers are proof of global warming, because they lack the science skills most people pick up in kindergarten.
Glaciers melt during interglacial periods (i.e. last 20,000 years) because more ice melts every year than accumulates. When this reverses, we are in an ice age.
According to Hansen, the years around 1910 were the coldest on record, yet Swiss glaciers were rapidly melting.
