Mt Kilimanjaro – the snow cover is increasing says Tanzanian minister

27 maj, 2008

Här kommer ett intressant uttalande av Ms Shamsa Mwangunga,The minister for Natural Resources and Tourism, i Tanzania i gårdagens The Citizen (Dar es Salaam).


”…says contrary to reports that the ice caps were decreasing owing to effects of global warming, indications were that the snow cover on Africa’s highest mountain were now increasing.

Among the signs of more snow is the decrease in temperatures in areas surrounding the mountain, heavy rainfall this year and increased precipitation and spring water flow on the slopes of the mountain,” she pointed out.”

She said reports that the ice caps at the 5,895 metres high mountain would disappear in the next 20 years were overblown because there were signs that the snow cover had increased in recent years.”

Det här var ju ett av paradnumren (tillsammans med isbjörnarna) i Al Gores Doom and Gloom show ”An inconvenient truth”. Och användes som ett ”avgörande” bevis för Global Warming Hysterikernas tes att CO2 driver temperaturen.

I en undersökning ”The Shrinking Glaciers of Kilimanjaro: Can Global Warming Be Blamed?” som presenterades i American Scientist, Volume 95, Number 4 (2007) gjord av Philip W. Mote, Georg Kaser (glaciologist, the University of Innsbruck) konstateras följande:

”But the commonly heard-and generally correct-statement that glaciers are disappearing because of warming glosses over the physical processes responsible for their disappearance. Indeed, warming fails spectacularly to explain the behavior of the glaciers and plateau ice on Africa’s Kilimanjaro massif, just 3 degrees south of the equator, and to a lesser extent other tropical glaciers. The disappearing ice cap of the ”shining mountain,” which gets a starring role in the movie, is not an appropriate poster child for global climate change. Rather, extensive field work on tropical glaciers over the past 20 years by one of us (Kaser) reveals a more nuanced and interesting story. Kilimanjaro, a trio of volcanic cones that penetrate high into the cold upper troposphere, has gained and lost ice through processes that bear only indirect connections, if any, to recent trends in global climate.

The fact that glaciers exist in the tropics at all takes some explaining. Atmospheric temperatures drop about 6.5 degrees Celsius per kilometer of altitude, so the air atop a 5,000-meter mountain can be 32.5 degrees colder than the air at sea level; thus, even in the tropics, high-mountain temperatures are generally below freezing. The climber ascending such a mountain passes first through lush tropical vegetation that gradually gives way to low shrubs, then grasses and finally a zone that is nearly devoid of vegetation because water is not available in liquid form. Tropical mountaintop temperatures vary only a little from season to season, since the sun is high in the sky at midday throughout the year. With temperatures this low, snow accumulates in ice layers and glaciers on Kilimanjaro, Mount Kenya and the Rwenzori range in East Africa, on Irian Jaya in Indonesia and especially in the Andean cordillera in South America, where 99.7 percent of the ice in tropical glaciers is found.”

”But Mote and Kaser say that the Kilimanjaro glaciers are not melting but sublimating-turning straight to vapor-under the direct action of solar radiation at temperatures that remain below freezing. Whatever is happening elsewhere, Kilimanjaro’s ice seems not to be succumbing to climate change.”

Figure 3. Kilimanjaro’s location in a dry and cold tropical climate zone changes its mass- balance equation. In the tropics glaciers do not move between winter and summer, snowfall and melting; temperatures vary more from morning to afternoon than from season to season. The ice cap on Kilimanjaro consists of ice on the 5,700-meter-high flat summit, some with vertical edges, and several slope glaciers, mostly at altitudes where temperatures stay well below freezing and the major source of energy is solar radiation. Considerable infrared radiation is emitted from the glacier surface into the surrounding air, and the glaciers lose the most mass through sublimation-the direct conversion of ice to water vapor. Observers have seen only a trickle of meltwater.

Och så här sa den engelske domaren om Al Gores film:

”A controversial documentary on climate change which has been sent to thousands of schools has been criticised by a High Court judge for being ‘alarmist’ and ‘exaggerated’.

Mr Justice Burton said former US vice-president Al Gore’s film, An Inconvenient Truth, was ‘one-sided’ and would breach education rules unless accompanied by a warning.

Despite winning lavish praise from the environmental lobby and an Oscar from the film industry, Mr Gore’s documentary was found to contain ‘nine scientific errors’ by the judge.

The judge then set out nine errors in the film which went against current mainstream scientific consensus:

Error 5: The disappearance of snow on Mt Kilimanjaro due to global warming. Judge: It cannot be established that the recession of snows on Mt Kilimanjaro is mainly attributed to human-induced climate change.”

Och så här sa reportern i New York Times i ett reportage där de besteg Kilimanjaro från den 21 januari 2008:

”I had wanted to climb to the roof of Africa before climate change erased its ice fields and the romance of its iconic ”Snows of Kilimanjaro” image. But as we trudged across the 12,000-foot Shira plateau on Day 2 of our weeklong climb and gazed at the whiteness of the vast, humpbacked summit, I thought maybe I needn’t have worried.

An up-and-down-and-up traverse of the south face of Kibo, the tallest of the mountain’s three volcanic peaks, showed us a panorama of the summit ice cap and fractured tentacles of glacial ice that dangled down gullies dividing the vertical rock faces. And four days later, when we reached 19,340-foot Uhuru, the highest point on Kibo, we beheld snow and ice fields so enormous as to resemble the Arctic.

It looked nothing like the photographs of Kibo nearly denuded of ice and snow in the Al Gore documentary ”An Inconvenient Truth.” Nor did it seem to jibe with the film’s narrative: ”Within the decade, there will be no more snows of Kilimanjaro.”

”Patchy snow covered the upper slopes above approximately 18,500 feet. At dawn, as we reached Stella Point at the lower lip of Kibo’s summit crater, the fluted walls of the flat-topped Rebmann Glacier stretched out to our left.

Snow blanketed the summit area, a mile and a half wide and hemmed by glaciers. Uhuru, the highest point in all Africa, was a 45-minute slog ahead.”
