In Denver, particularly so. Not one, but two new low maximum temp records have been set in Denver on two consecutive days. See the NWS record reports:

RECORD EVENT REPORT
NATIONAL WEATHER SERVICE DENVER CO
800 PM MDT SAT AUG 16 2008

…RECORD LOW MAXIMUM TEMPERATURE SET IN DENVER FOR AUGUST 16TH…

THE HIGH TEMPERATURE AT DENVER INTERNATIONAL AIRPORT TODAY WAS 58
DEGREES.

THIS 58 DEGREE READING WILL REPLACE THE PREVIOUS LOW MAXIMUM
TEMPERATURE RECORD FOR AUGUST 16TH WHICH WAS 63 DEGREES SET 118
YEARS AGO IN 1890.

Of course just a few days ago, they were talking about consecutive 90 degree days, and the possibility of a even longer new record, but it looks like the cold wet snap prevented that from happening: Read the rest of this entry »

Gore wrong on Kilimanjaro snow: Its the trees and “freezer burn”

17 08 2008

From the “we told you so” department, more agreement that Al Gore’s An Inconvenient Truth movie poster child for global climate change has nothing to do with climate change at all, and everything to do with local effects of land use change. This results in less wind laden moisture (via evapotranspiration) to deposit on the mountain and increased sublimation aka “freezer burn”. What next? Wrapping Kili’s glacier like the Germans are doing? – Anthony

Deforestation behind loss of Mt Kili snow

A scientific theory has linked the loss of snow on Mount Kilimanjaro to deforestation and dismissed suggestions that the dwindling of glaciers on Africa`s highest peak was due to global warming.

The theory is highlighted in a recent study report compiled by two researchers from Britain`s Portsmouth University, Nicholas Pepin and Martin Schaefer, who surveyed the mountain`s glaciers for 11 days.

The researchers, who revealed their findings at a news conference in Dar es Salaam yesterday, said the mountain`s glacier surface had shrunk from 20 km in 1880 to a mere two kilometres in 2000.

They said the development was caused more by local than regional factors, with Pepin suggesting that deforestation mainly due to extensive farming as the major cause.

“Deforestation of the mountain`s foothills is the most likely culprit because without forests there is too much evaporation of humidity into outer space.

The result is that moisture-laden winds blowing across those forests have become drier and drier,“ he explained.

“Loss of humidity automatically leads to a reduction in cloud cover. Clouds play a crucial role in protecting ice from sunrays, with fewer sunrays meaning faster freezing of water,“ he added, citing reduced precipitation as another reason for the receding ice cover on the mountain`s summit.

Last year, another study on the dwindling ice cover on the mountain`s cap suggested that global warming had nothing to do with the alarming loss of its beautiful snows. Read the rest of this entry »
