And not everyone’s voice is equal here. Knowledge matters. We must respect outside opinions but recognize when you are at the leading edge understanding what you disagree with is hard
You can disagree and argue as much as you like but the point of evaluating something scientifically is that not every statement should be given equal credence because evidence matters
JD Vance: "Science as practiced in its best form is that if you disagree with it, then you ought to criticize it and you ought to argue against it."

I am on my way home to Toronto and the aurorae are absolutely phenomenal.

If you are anywhere in the northern half of the continent, get outside and look up! Or better still, put your camera on a 10 second exposure and point it up.

Nights like this are the best. All the trouble of the world is momentarily set aside while we're collectively marveling at the pretty lights and nature together. This is how it's supposed to be. Life, I mean. Shared joy and all. 🙂

Even with the lights of Chicago those Northern lights are lighting!

An update from the NWS on the potential snow event. Read it.

One key: “…As a result, the expectation is for the lake effect snow bands to be unusually intense with peak snow rates of 3 to locally 5 inches per hour, frequent lightning and thunder, and pockets of hail.”

Stunning imagery!
The Copernicus Sentinel-2 polar-orbiting satellite made an extremely fortuitous pass over Hurricane Melissa right before it made landfall in Jamaica to provide these stunning images of one of the most powerful Atlantic hurricanes in history

The eyewall of Category 4 Hurricane #Melissa is about to exit Jamaica and re-emerge over very warm water (30-31°C) as it heads for eastern Cuba. How much rebuilding will it do?
I have a couple long radar loops from Pilon and Guantanamo at bmcnoldy.earth.miami.edu/tropics/radar/

#Melissa's landfall intensity of 185 mph/892 mb ties it with the Florida Key's Labor Day Hurricane of 1935 as the record minimum pressure of any TC making landfall *anywhere* the NATL basin. I feel for the residents of #Jamaica 😞

The most recent recon data suggests that Melissa continues to intensify. Central pressure now down to 907 mb and a dropsonde released in the northeast eyewall measured a mean wind in the lower 150m of 185 knots (213 mph). This hurricane is truly in rarefied air as far as Atlantic hurricanes.

Heads up Chicago. It's coming our way. Harvesting my remaining chillies and tomatoes today.
Could be a bit frosty tomorrow morning for southwestern parts of Wisconsin, as temperatures are expected to dip into the mid-30s. A Frost Advisory is in effect from 2 am until 9 am tomorrow.

Friday morning could be even colder, with a freeze looking possible for most of the state.

EV Chargers at work are STILL out today due to follow on issues. the AWS outage is case in point why unfettered consolidation is a BAD idea. We need regulators to black hat possible national issues when companies become... to big to fail...

THIS. Ev chargers at work are out today because of AWS. Over reliance on a single provider is making our technological society brittle.
#AWSOutage
Reliance on central cloud services has, in may ways, improved cybersecurity and stability around the world. But this standardisation comes with major tradeoffs—the platforms become a single point of failure for large swaths of critical services.
