It is a truism that any observed change in nature will be blamed by some experts on global warming (aka “climate change”, “climate crisis”, “climate emergency”).
When the Great Lakes water levels were unusually low from approximately 2000 through 2012 or so, this was pointed to as evidence that global warming was causing the Great Lakes to dry up.
Take for example this 2012 article from National Geographic, which was accompanied by this startling photo:
The accompanying text called this the “lake bottom” as if Lake Michigan (which averages 279 feet deep) had somehow dried up.
Then in a matter of two years, low lake levels were replaced with high lake levels. The cause (analysis here) was a combination of unusually high precipitation (contrary to global warming theory) and an unusually cold winter that caused the lakes to mostly freeze over, reducing evaporation.
Now, as of this month (June 2019), ALL of the Great Lakes have reached record-high levels.
Time To Change The Story
So, how shall global warming alarmists explain this observational defiance of their predictions?
Simple! They just invoke “climate weirding” and claim that the climate emergency has caused water levels to become more erratic, to see-saw, to become more variable!
The trouble is that there is no good evidence in the last 100 years that this is happening.
This plot of the four major lake systems (Huron and Michigan are at the same level, connected at the Straits of Mackinac) shows no increased variability since levels have been accurately monitored (data from NOAA Great Lakes Environmental Research Laboratory):
This is just one more example of how unscientific many global warming claims have become. Both weather and climate are nonlinear dynamical systems, capable of producing changes without any ‘forcing’ from increasing CO2 or the Sun. Change is normal.
What is abnormal is blaming every change in nature we don’t like on human activities. That’s what happened in medieval times, when witches were blamed for storms, droughts, etc.
One would hope we progressed beyond that mentality.

Yes, and California is still in permanent drought, as seen in the link below.

for decades now they have been screaming about the low water levels in the great lakes!
Some people are total suckers they fall for anything their told and they beleive everything thay see on CNN or read in the NYT’s and their willing to send in money to some fake cause like SAVE THE POLAR BEARS, SAVE THE RAIN FORESTS, Etc
In 2012, global warming was mainstream claptrap. Drought hit the Midwest hard. The Great Lakes were low. Now climate change is the Devil threatening imminent climate catastrophe. The Great Lakes are high. You have to be gullible to believe it.
Here in Michigan we had quite a bit of snow this winter with snow causing the postponement of several major league baseball games in April and a light snow falling in May — a rare occurance — This late-coming Spring pushed the “April showers” to fall heavily in May and early June. Also this year, the Great Lakes were nearly 100 present frozen over, and none of the water which made up the ice (or snow atop the ice) was able to flow off the lakes. Since Michigan lies in the center of four of the Great Lakes, I assume that surrounding areas had similar weather. For those of you who are not familiar with the Great Lakes, the Great Lakes watershed is enormance. A great part of Ontario, Canada, and all or part of the following states: Michigan, Minnesota, Wisconsin, Illinois, Indiana, Ohio, Pennsylvania, and New York — are part of the Great Lakes watershed.
also this year, You don’t have to be too bright to figure out the snow melt and rain from this vast area have to run off somewhere, and that “somewhere” is the Great Lakes. The lake levels around Michigan have risen and fallen many times. No one should take the level of any given year as “typical”. Wait a few years to see what happens.
Back in 1963 when Carson’s Junk Science book Silent Spring was making all this bunk about DDT and its so called impact on Birds and how it effected their ability to reproduce in the 1970’s they banned DDT because of this lie in the 1990’s it was The Rain Forests now its Global Warming/Climate Change when also back in the 1970’s it was Global Cooling and New Ice Age was coming this is all a attempt to force the New World Order on us all with the Democrats doing the dirty work someone else is pulling the strings
They changed the story from Global Cooling in the 70’s to Global Warming in the 2000’s, to Climate Change.
Anything that happens is because of human activity. Not the sun. Not volcanic or tectonic action. Nothing but humans. So we can control our destiny. Except we can’t. We are at the mercy of mother nature, a force greater than us.
Deal with it, Climate Alarmists.
