Global Warming

[someone036]

I have been unsure about global warming, since I don't know much about it, but this has definitely given me some views on it: There has been snow on Mount Kilimanjaro for the past 11,000 years. It is gone now.

Yeah, because look at all the pictures and documented journals proving that snow has been there that long.....and what was there prior to 11,000 years ago....perhaps its just now returning to normal.

Who let this troll in.....hes muking up the carpet dammit!

may I just add that the oldest piece of documented history is 5,000 years old and hmmm,

it doesn't say anything about a snow covered mountain.

And your point is? Anecdotal "evidence" such as that is meaningless. The only evidence that is meaningful are actual temperature measurements and those show that global temperatures have risen by less that 1 degree Celsius in the 100+ years since the end of the 500-year Little Ice Age. In other words, the temperature increase is natural and there is nothing that humans can do about it.

If you want more meaningful anecdotal evidence, the 2 largest glaciers in the world that make up 90% of all the world's glaciers - the Antarctic Ice Cap and the Greenland Ice Cap - are both thickening and expanding.

Here is why it is shrinking:

Excerpt:



When Thompson's reports of glacial recession on Kilimanjaro first emerged in 2002, the story was quickly picked up and trumpeted as another example of humans destroying nature. It's easy to see why: Ice fields in the tropics—Kilimanjaro lies about 220 miles (350 kilometers) south of the Equator—are particularly susceptible to climate change, and even the slightest temperature fluctuation can have devastating effects.

"There's a tendency for people to take this temperature increase and draw quick conclusions, which is a mistake," said Douglas R. Hardy, a climatologist at the University of Massachusetts in Amherst, who monitored Kilimanjaro's glaciers from mountaintop weather stations since 2000. "The real explanations are much more complex. Global warming plays a part, but a variety of factors are really involved."

According to Hardy, forest reduction in the areas surrounding Kilimanjaro, and not global warming, might be the strongest human influence on glacial recession. "Clearing for agriculture and forest fires—often caused by honey collectors trying to smoke bees out of their hives—have greatly reduced the surrounding forests," he says. The loss of foliage causes less moisture to be pumped into the atmosphere, leading to reduced cloud cover and precipitation and increased solar radiation and glacial evaporation. Evidence of glacial recession on Kilimanjaro is often dated from 1912, but most scientists believe tropical glaciers began receding as early as the 1850s. Stefan L. Hastenrath, a professor of atmospheric studies at the University of Wisconsin, Madison, has found clues in local reports of a dramatic drop in East African lake levels after 1880. Lake evaporation indicates a decrease in precipitation and cloudiness around Kilimanjaro.
