An American-Canadian Treasure
The Great Lakes have one of the longest hydrographic records in North America.
It’s amusing, but also tragic, to see how the National Geographic magazine has attempted to use the Great Lakes in its efforts to promote CO2 as the cause of climate change.
Again, in this month’s issue, they have highlighted pictures that supposedly show the effects of climate change. One picture is of a woman standing on a spit of land in India’s Ganges River Delta, with water swirling around her, with the caption, “Conditions that could possibly be attributed to climate change.”
A few years ago, they used similar pictures from the Great Lakes to show that the Great Lakes were drying up due to climate change. They retain these articles on their website.
One article is entitled Down the Drain, with the headline:
“The Great Lakes hold a fifth of Earth’s surface fresh water, and they’ve shrunk dramatically. If it keeps up, shipping and fisheries could be left high and dry.” (Emphasis added.)
The National Geographic is not alone in ignoring science.
For example, the editor of Power Magazine had to issue a retraction over his claim that the oceans would rise 11.9 feet in 100 years and threaten Florida. (The actual text has been removed from the magazine’s archives.)
Fortunately, science, combined with some critical thinking, can be used to examine these absurd claims. For example, the editor of Power Magazine had to issue a retraction after a reader brought his incorrect statement to light.
In the case of the Great Lakes, there is a record of surface water levels going back to the 1800s.
Lakes, historic hydrographic record
The charts show that nearly all the Great Lakes are above their long-term average levels.
The charts show that water levels in all the Great Lakes have varied over the past century and a half.
- Lake Superior had its lowest water level in 1926.
- Lakes Michigan-Huron had their lowest water levels in 1964.
- Lake Erie had its lowest water levels between 1934 and 1936.
- Lake Ontario had its lowest water level in 1965.
When all the lakes are viewed together, it’s clear that levels have risen and fallen for various reasons since 1860.
There is no apocalypse due to global warming.
Perhaps even more threatening than media attempts to scare people is the attempt by the EPA to use the Great Lakes as a climate change indicator.
This is an outrageous effort by the government to influence people about a political issue.
The EPA’s attempt is pathetic since their evidence refutes their use of the Great Lakes as a climate change indicator, despite their attempt to distort the actual historic record.
The EPA website is especially pernicious, because it should be a trustworthy source, not an Orwellian purveyor of misinformation.
For those interested in evaluating the above comments for themselves, the links to the historic record and the EPA’s attempt at influencing people are shown here:
