The 35 Errors In "An Incovenient Truth" - Part 9

ERROR 22 Mountain glaciers worldwide "disappearing"

Gore says that “the ice has a story to tell, and it is worldwide.” He shows several before-and-after pictures of glaciers disappearing.

The Facts:

The glacial melt began in the 1820s, long before humankind could have had any effect, and has continued at a uniform rate since, showing no acceleration since humankind began increasing the quantity of CO2 in the atmosphere. Total ice volumes in three of the last four Ice Ages were lower than they are today, and “global warming” had nothing to do with that.

Despite Al Gore’s claim that glaciers are “disappearing” world wide, he clearly forgot to mention these ones that are growing in some cases for the first time in 250 years.

NORWAY : Ålfotbreen Glacier, Briksdalsbreen Glacier, Nigardsbreen Glacier
Hardangerjøkulen Glacier, Hansebreen Glacier, Jostefonn Glacier,
Engabreen glacier ;
FRANCE: Mt.Blanc;
SWITZERLAND: Silvretta Glacier;
RUSSIA: Maali Glacier;
GREENLAND: glacier advancing 7.2 miles per year!;
NEW ZEALAND: All 48 glaciers in the Southern Alps have grown during the past year, most notably the Fox, Franz Josef glaciers.
SOUTH AMERICA: Argentina's Perito Moreno Glacier; Chile's: Pio XI Glacier;
ECUADOR: Antizana 15 Alpha Glacier;
UNITED STATES: Colorado, Washington (Mount St. Helens, Mt. Rainier*and Mt. Shuksan), California (Mount Shasta)' Montana, Glacier Peak, Washington, Alaska (Mt. McKinley and Hubbard first time in 250 years).
CANADA: Helm Glacier, Place Glacier
HIMALAYER’S: in the Hindu Kush and the Karakoram.

So it could also be argued there is world wide growth of Glacier’s too.

ERROR 23 Sahara desert "drying"

Gore says terrible tragedies are occurring in the southern Sahara because of drought which he blames on “global warming.”

The Facts:

There is no drought caused by “global warming.” In 2007 there were record rains across the whole of the southern Sahara. In the past 25 years the Sahara has shrunk by some 300,000 square kilometres because of additional rainfall. Some scientists think “global warming” may actually mitigate pre-existing droughts because there will be more water vapor in the atmosphere. Before 1200 AD there were frequent, prolonged and severe droughts in the Great Plains. Since 1200 AD, there has been more rainfall. Likewise, the US has had more rainfall since the 1950s than it had in the earlier part of the 20th Century, when the great droughts which were then common were described by John Steinbeck in The Grapes of Wrath. South African rainfall was also more stable in the second half of the 20th Century, when human effect on climate is said to have become significant, than in the first half.
