Unprecedented melting of glaciers !
“Glaciological and geodetic observations (~5200 since 1850) show that the rates of early 21st-century mass loss are without precedent on a global scale, at least for the time period observed”
Dr Michael Zemp, director of WGMS
As ~ 1850 was the glacial maximum of the Little Ice Age, glaciers should still be receding at ever-increasing speed.
“without precedent” – I’m sorry but history says different –
26 May 1906 – “The latest report includes 90 glaciers in the Swiss Alps, in Norway, Greenland, the Caucasus, the Pamir, the North West United States, Western Canada. and Africa, and practically all are growing smaller. In the Savoy Alps and the Pyrenees small glaciers have quite disappeared.” http://trove.nla.gov.au/newspaper/article/38087689
21 November 1908 – ” There has been a general retreat, he says, of the European glaciers since 1861.”

During the Little Ice Age (LIA), alpine glaciers around the world reached their maximum Holocene extents, generally dating back to about 1500 AD. There followed several periods of cooling and warming when repeatedly glaciers expanded and retreated. Glaciers during the cool period of 1880 to 1915 reached almost to their LIA maxima, retreated during the 1915 to 1945 warm period, expanded again during the 1945-1977 cool period, and retreated during the 1978 to 2000 warm period.

Other surging glaciers
Since measurements began in 1895, Alaska’s Hubbard Glacier has been thickening and steadily advancing into Disenchantment Bay. The advance runs counter to so many thinning and retreating glaciers nearby in Alaska and around the world. More details here.

Ancient stumps and logs have also been popping out from under southern Alaska’s Mendenhall Glacier.

& you may want to consult Ötzi the iceman on what the glaciers where like then – https://en.wikipedia.org/wiki/Ötzi

That tells us it was at least 2~4 °C warmer when the forest grew & before the glaciers started, also that glaciers surge naturally…without mans intervention.
