Global environmental challenges
When he wrote “The Snows of Kilimanjaro” in the 1930s, Ernest Hemingway described the summit of that African mountain as “wide as all the world, great, high, and unbelievably white in the sun.”
It’s still wide, but may not be white much longer, according to a new study published in the Proceedings of the National Academy of Sciences that says the remaining ice fields atop Kilimanjaro in Tanzania could be gone in 20 years or less, a casualty of climate change. Changes in clouds and precipitation play a minor role but the scientists say it’s mostly due to global warming.
Here’s the trail of data released by the National Science Foundation, which helped fund the research:
– 85 percent of the ice that covered the mountain in 1912 had been lost by 2007, and 26 percent of the ice there in 2000 is now gone.
We hear a lot of grim news about how sea ice has been melting more than usual in recent summers in the Arctic, how glaciers from the Himalayas to the Andes are melting or how winter sports such as ice hockey in Canada may be under threat from global warming.
