The retreat of glaciers since 1850 is a well-documented effect of climate change. The retreat of mountain glaciers provide evidence for the rise in global temperatures since the late 19th century. Examples include mountain glaciers in western North America, Asia, the Alps in central Europe, and tropical and subtropical regions of South America ...
The retreat of the Laurentide Ice Sheet in Canada led to the formation of moraines and up to 26 proglacial lakes scattered throughout central Canada. The deglaciation occurred from the last glacial maximum (21,000 years ago) to 7000 years ago. Some of the lakes in the southern Ungava Bay area were fully deglaciated c. 6,000 years ago. [5]
1816 Year Without a Summer, caused by volcanic dust of Mount Tambora eruption; 1850–present Retreat of glaciers since 1850, instrumental temperature record; Present and recent past global warming, perhaps to be named the Anthropocene period

The Last Glacial Period caused a much lower global sea level This glaciation radically altered the geography north of the Ohio River , creating the Great Lakes . At the height of the Wisconsin Episode glaciation, the ice sheet covered most of Canada , the Upper Midwest , and New England , as well as parts of Idaho , Montana , and Washington .
A warming climate has melted three glaciers on Mount Rainier, the tallest volcano in the lower 48 states — more evidence of the rapid worldwide decline of mountain ice.
An important aspect of glacier development is that temperatures during the rest of the year should not cause the complete loss of the previous winter’s snow accumulation, this is how glaciers ...
For example, interruptions of the usual deep cold water circulation and penetration depths in the North Atlantic have feedbacks that promote further glacial retreat. [19] Deglaciation influences sea level because water previously held on land in solid form turns into liquid water and eventually drains into the ocean.
