Climate Rappin' -- Great Lakes Are Too High, Or Too Low -- Who Cares ?

I moved to Michigan from New York in July 1977. Here we are partially surrounded by Great Lakes, not that I see them often. 
But articles about the lakes are common. 
It seem like once in every decade, the local media get hysterical about the Great Lakes water level. The water level is either too low, or too high. I'm not sure the water level is ever 'perfect' !

I have a file of articles on the subject, from the past decade, taking up space in my computer. But I don't know the years the old articles were written.
Maybe it doesn't matter. 

After all, some people were hysterical about climate change in the 1970's, 1980's, 1990's, 2000's and 2010's. What difference does the decade make?  Climate alarmism all sounds the same to me. And despite our wonderful climate, they are now more hysterical than ever !

The climate on our planet has warmed a lot for 20,000 years.  That's good news because my acre was under an ice glacier 20,000 years ago.  10,000 years ago the large majority of climate proxy studies revealed the climate was slightly warmer than today.

The current mild warming trend has been in progress since the late 1600s -- about 325 years. For the past 50 years, climate alarmists have been warning us of a coming climate crisis ... that never shows up.. They consistently predict two to three times the global warming that actually happens. And they ONLY use a global average temperature, that not one person lives in. Averages hide important data. Based on a national average IQ, Bill Gates' intelligence is just average!

Using a single average temperature disguises the fact that post-1975 warming was mainly in the northern half of the Northern Hemisphere, mainly in the coldest six months of the year, and mainly at night. The actual warming is mainly in places, and at times, that are good news!  Alaska has warmer winter nights. Is that an existential  crisis?  It's not even a minor problem. it's good climate news.

Water level alarmism about the Great Lakes is a subset of the global climate alarmism. Here are some quotes from a June 2020 article, and two older articles, with unknown dates, from the past decade. This is how climate change writers get attention:


"Three Great Lakes and Lake St. Clair set record high water levels in May.
The forecast for water rising to mid-summer shows an all-time high water mark is possible since good records began 102 years ago."

Lake Michigan and Lake Huron topped the previous May water level record by 4 inches. This extra water represents 3.2 trillion gallons that Lake Michigan-Huron never had in a month of May.

All of the Great Lakes are in their normal seasonal rise, and usually peak water levels are reached around July."


Great Lakes high water ‘is going to affect everyone in Michigan."


from nationalgeographic.org:
"The upper Great Lakes reached near-record low water levels in October.
This was most evident on Lakes Michigan and Huron, where lake levels dropped to less than two inches (4 cm) above record lows and 28 inches (71 cm) below the long-term average. All five lakes, plus Lake St. Clair, remain below their long-term averages.

Rock and sand recently exposed by low water levels made stretches of the northern Lake Michigan shoreline look like a moonscape. Recreational boaters had trouble navigating the shallow water this fall, and shipping companies lightened loads to compensate for low water. Lakes Michigan and Huron hovered just above a record low set nearly 50 years ago, and Lake Superior was within five inches (11 cm) of a record low set in 1925."

from michiganradio.org
"Lake Michigan is approaching a record low water level. Just about a half a meter less, and the record will be beat. That's how much the water level in Lake Michigan would have to drop to reach the record low level set in March of 1964.
In that month, the Lake Michigan water level was measured at 175.58 meters above sea level. This past July, it was measured at 176.04 meters above sea level.


Mark Breederland, an extension educator for the Michigan Sea Grant, said Lake Michigan is 23 inches below the long-term average.  Lakes Michigan and Huron are in the midst of a decade-long stretch of below-average water levels, said Keith Kompoltowicz, chief of watershed hydrology at the U.S. Army Corps of Engineers' Detroit District."
