Hi Guys
I saw once a couple of iceblocks remaining earlier this year in a news report on Kilimanjaro, Wiki has this to say
In the late 1880s the summit of Kibo was completely covered by an ice cap with outlet glaciers cascading down the western and southern slopes, and, except for the inner cone, the entire caldera was buried. Glacier ice flowed also through the Western Breach.[31]
An examination of ice cores taken from the North Ice Field Glacier indicate that the "snows of Kilimanjaro" (aka glaciers) have a basal age of 11,700 years.[32][33] A continuous ice cap covering approximately 400 square kilometers covered the mountain during the period of maximum glaciation, extending across the summits of Kibo and Mawenzi.[34] The glacial ice survived drought conditions during a three century period beginning ~2200 BCE.[35]
The period from 1912 to present has witnessed the disappearance of more than 80% of the ice cover on Kilimanjaro. From 1912-1953 there was ~1% annual loss, while 1989-2007 saw ~2.5% annual loss. Of the ice cover still present in 2000, 26% had disappeared by 2007. While the current shrinking and thinning of Kilimanjaro's ice fields appears to be unique within its almost twelve millennium history, it is contemporaneous with widespread glacier retreat in mid-to-low latitudes across the globe. At the current rate, Kilimanjaro is expected to become ice-free some time between 2022 and 2033.[35]I just thought I give an example far away from Canada. Now from that you can see change from 1912 but see
