This is fascinating.

https://www.washingtonpost.com/climate- ... ford-lake/

tl;dr:
The sharpest sign of change was a surge in radioactive plutonium that started in Crawford Lake’s mud around 1950. The element rarely occurs naturally on this planet; it could only have come from nuclear weapon tests happening thousands of miles away.

Other shifts weren’t necessarily new, but they appeared at scales ten or a hundred times greater than anything the lake had seen before. A lighter form of nitrogen — a molecular signature of burning fossil fuels — proliferated. The amount of fly ash increased eightfold in less than five years. Acid rain, caused by pollution reacting with water in the atmosphere, diminished the calcite layers.

Still more sediments recorded irreversible losses. Certain microbe species were eliminated locally. The amount of elm pollen plummeted — a consequence of the invasive fungus that was decimating North America’s tree populations at the time.

All the while, greenhouse gas pollution made the planet inexorably hotter. The lake’s calcite layers became thicker during warm years; pollen grains show how the forest composition shifted to include more heat-loving tree species.

Average temperatures in southern Canada have increased about 1.5 degrees Celsius (2.7 degrees Fahrenheit) in this time. The globe as a whole is now warmer than it’s been at almost any point since the end of the last ice age.

These changes all are the result of what scientists call “the Great Acceleration” — the dramatic, simultaneous surge in almost every measure of human activity that started in the mid-20th century and continues through today.

The same evidence appears all over the planet, in every potential golden spike site the Anthropocene Working Group has examined. Peat bogs, ocean basins, the skeletons of coral reefs — even the ice of Antarctica has been permanently tainted by human pollution.

“What we have measured, in a very objective and quantitative way, is we are living in a world with conditions that are no longer within the last 11,000 years of natural variability,” McCarthy said. “The Earth is, in fact, fundamentally different.”
It simply is not true that what we're experiencing are the natural ebbs and flows that would have happened without our involvement.

kind of a, um, frightening perspective?

I have lived in the city of Chicago for 28 years. I have never hear the tornado sirens go off as much as they have been going off this evening. Thankfully for me much of the bad stuff is happening to the North, South, and West. I do feel very sympathetic for those who are in danger.

It was pretty wild. I saw one trying to form, and it dissipated

Glad you're ok!

I went up on the rooftop after the storm. Took a few pics and videos. Videos are much better but I struggle figuring out how to post them on here.
In the mean time, a few pics......

Tornado sirens on and off several times in last 15. Currently can’t see Lyons park from my windows (40 yards away).

Definite wall cloud came in around Clinton and wrapped north. I was by 6th street dillons and turned around and drove about 110 for a mile on the KTA to secure my kitties and such.

While posting update. Rain mixed with hail it seems.

Defix—-just left to go check on my sisters place. RR bridge flooded, traffic backed up almost to Elmo’s when I was getting out. I’d stay in for a bit if you had plans to leave

Thanks for the heads up! There are two or three more rounds of severe weather tonight so I think I'm just going to stay in so I can make a mad dash to the basement if need be.

Glad you guys are ok!
Stay home tonight and look out your window/s to see old bitches riding their bicycles.

Earlier today the weather forecasters were predicting a bad storm around 6:30 tonight but it never materialized. I'm kind of bummed being that I am inside and have no plans to go out tonight.

My son's girlfriend was flying into Kansas City from Toronto late this afternoon just when the storms hit. They turned her plane around and sent them back to Toronto. I don't know if she'll try to get back tonight or first thing in the morning or somewhere in between.

Basement? Nah. Summer between my junior and senior year of college we had about 5 tornado warnings. Our basement of the PoS home we rented was scary af. So instead our procedure was go to fridge, grab beer, and go out to the porch to look for the tornado.

Got to see one form then go away, the rest were nothing.
