Here’s a recent report, posting a video from 2014 saying the glaciers could be gone by 2020. The report itself, headlined ‘Mount Kilimanjaro’s Glaciers Estimated to be Gone by 2030’, says: ‘In 2006, National Geographic News published some stunning satellite images of Africa, courtesy of United Nations Environment Program. One of the images shows the glacial retreat occurring on Mount Kilimanjaro between 1976 and 2006. Earlier predictions of the glaciers disappearing by 2020 were obviously incorrect.’ (Al Gore was in the 2020 camp).
The next line is interesting: ‘Glacial retreat is attributed to lower precipitation, and not global warming.’ No research is quoted to support that statement, but this journal article says: ‘During the last 120 years, annual precipitation on Mount Kilimanjaro (Tanzania) has decreased by 600–1200 mm (Hemp, 2005a)’. UNESCO pushes the usual CO2 climate theory and hazards another prediction, much more cautious now, as COP27 is about to start.

Glaciers at many UNESCO World Heritage sites including Yellowstone and Kilimanjaro National Park will likely vanish by 2050, the UN agency warned Thursday, urging leaders to act fast to save the rest, reports Phys.org.
The warning followed a study of 18,600 glaciers at 50 World Heritage sites—covering around 66,000 square kilometres (25,000 square miles)—which found glaciers at a third of the sites were “condemned to disappear”.
The study “shows these glaciers have been retreating at an accelerated rate since 2000 due to CO2 emissions, which are warming temperatures”, UNESCO said.
The glaciers were losing 58 billion tonnes of ice every year, equivalent to the combined annual water use of France and Spain, and were responsible for nearly five percent of observed global sea-level rise, the agency explained.
“Glaciers in a third of the 50 World Heritage sites are condemned to disappear by 2050, regardless of efforts to limit temperature increases,” UNESCO said.
“But it is still possible to save the glaciers in the remaining two thirds of sites if the rise in temperatures does not exceed 1.5°C compared to the pre-industrial period.”
Countries have pledged to keep global warming to 1.5 degrees Celsius above pre-industrial levels—a goal the world is set to miss on current emission trends.
“This report is a call to action,” said UNESCO head Audrey Azoulay, ahead of the COP27 climate summit in Egypt starting on Monday.
