Global warming was blamed for evaporating the Great Lakes, now blamed for high water levels in Chicago’s ‘climate emergency’ – Updated 2

Global warming was blamed for evaporating the Great Lakes, now blamed for high water levels in Chicago’s ‘climate emergency’ – Updated 2

“What we are seeing in global warming is the evaporation of our Great Lakes.” That was Illinois Senator Dick Durbin in 2013 when Lake Michigan was at a record low. You can find plenty of claims to the same effect from the time. Nobel Prize winner Al Gore chimed in around then, too, saying climate change was driving Great Lakes levels down by causing evaporation.

But that was then and this is now.

What’s causing today’s record high levels? Climate change, naturally.

So now, citing “catastrophic lakefront erosion” from high water, Chicago just declared a climate emergency. It’s radical, and is reproduced in full below.

Mayor Lori Lightfoot and Durbin want the federal government to help Chicago pay for damage to its shoreline. Lightfoot’s accompanying statement is reproduced below. You’ll be relieved to see that she’s putting “equity” at the center.

Given that Lightfoot hasn’t exactly been friendly to President Trump, you might be concerned about what reception her request for federal help will get. Per the Chicago Tribune, Lightfoot acknowledged “some concern, of course,” that President Donald Trump won’t see the urgency in sending help to Chicago — a city he has treated as a public antagonist for years — to combat climate change, an issue he hasn’t deemed a high priority.

Why, yes, I’d have some concern, too, of course. She called Trump’s visit to Chicago “insulting, ignorant buffoonery.” Not that he’s vindictive or anything.

And since sustainability is emphasized in Lightfoot’s statement, I’d also have some concern about sustainability of claims about the causes of Great Lakes water fluctuations. I confess to being old enough to remember exceptionally high lake levels in the late 1970s when global cooling was blamed.

Nestlé’s Profits Trump Clean Water in Flint

Nestlé’s Profits Trump Clean Water in Flint

Screw the people of Flint, or so goes the mantra of the Michigan Department of Environmental Quality (MDEQ), which last month approved a controversial permit that will allow Nestlé to pump and bottle 400 gallons of fresh water per minute from the state’s White Pine Springs, near the Osceola Township. Meanwhile, back in Flint, residents still aren’t buying the Governor’s bullshit that their water is safe to drink.

The privatization of the public’s water is only becoming more prevalent as reservoirs dry up around the globe. Bottled water sales have skyrocketed in the last ten years while access to fresh, affordable H20 has decreased. In places like Cape Town, South Africa, which is in the midst of a dire water shortage, it’s not just climate change that’s making the city quench for thirst — the impoverished can’t afford private water but residents with money are able to subsidize their meager rations.

“Many of the rich own water-bottling companies, they can afford to buy water,” Ebrahiem Fourie of the Cape Town Housing Assembly recently told journalist Dahr Jamail. “The available ground water [springs] are usually in affluent areas, which makes them easy to access, and with the current water restrictions the rich have cars to load their water.”

Mega-corporations like Coca-Cola and Nestlé may seem like a nice solution for communities that don’t have access to clean drinking water. Their water is potable, portable and generally safe. However, as we are witnessing in Cape Town, private companies in the water business cater to those with cash. The poor are left out to dry. Deals like Nestlé is scoring in Michigan won’t fix the water problem in Flint — which is one of the poorest communities in the nation — it will likely exacerbate it.

The pumped hydro storage potential of the Great Lakes

The pumped hydro storage potential of the Great Lakes

The potential energy contained in the waters of the Great Lakes amounts to approximately six thousand terawatt hours, enough to supply the US and Canada with electricity for an entire year were the lakes to be drained to sea level. This of course will never happen, but there may be potential for partial utilization of the resource. A pumped hydro system that uses Lakes Huron and Michigan as the upper reservoir and Lake Ontario as the lower could theoretically generate 10 terawatt-hours, or more, of seasonal energy storage without changing lake levels significantly. The most likely show-stopper is the increased likelihood of flooding in the lower St. Lawrence River during pumped hydro discharge cycles. (Inset: Niagara falls runs dry in 1969).


The idea of using the Great Lakes for pumped hydro storage isn’t new – I remember reading about it once before but can no longer find the article. What brought it back to mind was a comment posted by Alex on the recent 100% renewable California thread in which he agreed that while there were indeed no fresh water lakes that no one cared about there were some that could perhaps be adapted for pumped hydro without anyone noticing:

Alex says:

“The only existing fresh-water lakes that would be feasible targets for large-scale pumped hydro are in fact those that no one cares about.”

Or perhaps those that are so big you won’t notice the change. Here is a modelling challenge: Lake Ontario and either Lake Erie or Lake Huron.

I estimate 6TWh per metre elevation change in Lake Ontario.

Last record-breaking winter with snow hits Canada, US, before “nobody knows what snow is”

Last record-breaking winter with snow hits Canada, US, before “nobody knows what snow is”

UPDATE: Record breaking snow falling in upstate New York. Pennsylvania.

The airport in Erie, Pennsylvania, has had a whopping 65.1 inches of snow from this lake effect event — the highest snowfall total from any event on record in Erie. (Heavy lake effect snow is produced by cold Arctic air moving over relatively mild water temperatures in the Great Lakes.) — World News, ABC (US) News

40,000 people in Cleveland lost power overnight.

New York City may have coldest New Year’s Eve since 1960s… — ABC News

In freak conditions, Canadians (and many people in the US too) are getting a chance to enjoy record cold for the last time before climate change makes winters unbearably mild.

Extreme cold in Toronto smashes 57-year-old temperature record

Temperatures observed at Toronto’s Pearson International Airport bottomed out at -22 C [-7.7F]  this morning. The previous record for this date was set in 1960, when it hit -18.9 C. [-2F]

Tristan Hopper does some first class bragging about the cold:

Mars and the North Pole are warmer than Winnipeg: A guide to how damned cold it is

Vancouver is as cold as Moscow, Toronto is colder than CFS Alert and a piece of the country roughly the size of Europe was under an extreme cold warning

It’s colder in Winnipeg than it has ever been in Scotland (ever)

The coldest ever in Scotland was apparently only – 27C. (-16.6F). And for southerners, “CFS Alert” is the worlds most northern inhabited place, deep into the Arctic, and beyond even where Inuits would live. Today, by the way, in midsummer the South Pole warmed up to -18C.

Scientific concern begins over lack of Great Lakes’ ice

Scientific concern begins over lack of Great Lakes’ ice

Thursday, February 4, 2016, 2:56 PM – Ice coverage on the Great Lakes is near record-low levels for this time of year, and scientists are concerned about the effect this will have on wildlife species in the months to come.

Southern Ontario set some record high temperatures on Wednesday, February 3, 2016. For example, the afternoon high of 16oC at Toronto’s Pearson International Airport managed to beat out all other records for the day in the city going back to 1842. It was also the highest daily temperature ever recorded for Toronto in the month of February going back 174 years.

While typical February chills were interrupted by this unusually balmy day, the Great Lakes were still feeling the effects of an already unusually warm winter, with some of the lowest ice coverage numbers on record.

Back on January 11, coverage was logged at just 3.8 per cent – remarkably low, given what the previous two years were like by that time of the year, and largely a consequence of a warm December thanks to the strong El Niño pattern in the Pacific Ocean.

Since then, although there were a few days in the latter half of January where coverage actually got up into the double-digits, as of February 3, only 5.7 per cent of the lakes were covered with ice.

By comparison, in 2015, ice coverage was at 50.5 per cent, while in 2014 – the year with the second highest coverage on record since 1973 – it was 71.6 per cent.

The unusually large expanse of open lake water so far this winter has been providing fuel for some pretty intense snow squalls. Looking at the current forecast for the rest of February, with a cold snap is expected going into Week 2, and then a return to mild weather later in the month, it’s likely that will continue, even with a slight rebound in ice coverage that should come during that cold snap.

Microplastics at ‘alarming levels’ in Canadian lakes and rivers

Microplastics at ‘alarming levels’ in Canadian lakes and rivers

Microbeads just tip of plastic iceberg floating in Canadian waters

Tiny plastic pellets called microbeads have gotten a lot of attention as a major water pollutant, but less-discussed microplastics are equally concerning, according to new research being done in Canada.

“In recent years, they’ve been detected in a growing number of lakes and rivers worldwide. They’re everywhere, and often in alarming levels,” said Anthony Ricciardi, a professor at the McGill School of the Environment, who is working on a study about microplastics.

Microplastics are small particles of plastic less than five millimetres in size that are often found in bodies of water near large urban populations. Microbeads, which are used in toothpastes, makeup and body cleansers, are one part of the broader category of microplastics.

Microbeads are “getting all the attention, but they’re only one component to this,” Ricciardi said. “As time goes on, people are going to realize the importance of the other pieces, too.”

A 2014 study of the U.S. Great Lakes by the 5 Gyres Institute found an average of 43,000 microplastic particles per square kilometre. Near cities, the number jumped to 466,000.

Dislodged from clothing in the wash

The plastic particles in the Great Lakes include microbeads, but also come from other sources, such as bits of polymer that detach from clothing when it is washed, as well as granules from industrial abrasives.

Cheers! Ontario takes action to limit water transfers within the Great Lakes basin | – Environmental Defence

Cheers! Ontario takes action to limit water transfers within the Great Lakes basin | – Environmental Defence.

By Anastasia Lintner, Lintner Law and Nancy Goucher, Environmental Defence

Last Thursday, the Government of Ontario filed a new regulation that, commencing on January 1, 2015, will stop diversions of water from one Great Lakes watershed to another (save for well-defined exceptions).  With this new regulation, Ontario has finally fulfilled its commitments under an agreement we have with Quebec and the U.S. Great Lakes states, so that both Canadian and U.S. jurisdictions must follow strict standards and procedures should they want to move major amounts of water within or outside of the Great Lakes-St. Lawrence River Basin.

The Great Lakes may seem like a limitless resource (we often hear that these lakes hold almost 20 per cent of the world’s available surface freshwater), but in reality, these water bodies are not as stable as some might like to think. About 99 per cent of the water we see is left over from when the glaciers melted some 10,000 years ago. That means only one per cent of the water in the lakes is renewed annually. If more than that leaves the system in a year, water levels will decline. That’s why we need to guard our water supplies and carefully control how much water we artificially move between watersheds.
