The 7 hottest days on Earth in the last 100,000+ years all happened in the last week: July 6 ~ 17.23°C / 63.01°F July 7 ~ 17.20°C / 62.96°F July 4 ~ 17.18°C / 62.93°F July 5 ~ 17.18°C / 62.92°F July 8 ~ 17.17°C / 62.90°F July 10 ~ 17.12°C / 62.81°F July 9 ~ 17.11°C / 62.79°F

Just to be perfectly clear. We are witnessing, in real time, the collapse of civilization. It's pretty f&%king horrible, even for a doomer who knew this was coming eventually, I've got to say. Pretty f&%king horrible.

Another day, another record for the North Atlantic. Everything is happening so fast, it's hard to get a sense of the enormity of these anomalies, let alone their consequences.

My simple thought on Truss as PM: I am now convinced that the UK is going to be the first "first world" country to completely implode and collapse, and that its going to happen very soon, maybe by next summer. I have no idea what this will trigger worldwide, but it won't be good.

Wow! Wow! Wow! North Atlantic sea surface temperature anomalies are going vertical again. And yes, I needed to extend the y-axis. Yesterday's temperature of 24.49°C (76.08°F) was 4.2σ above the 1991-2020 mean. The previous high for July 17 was 23.71°C (74.68°F) in 2020.

Wow, just wow. The planet is breaking. Antarctic sea ice extent is the headline for me this morning. There was actually a net *decrease* in ice extent day over day, and it's mid-winter there, peak freeze season. Extent is now 6.4 standard deviations below the 1991-2020 mean.

Breaking News! Well humanity, we did it, even if just for one day. Yesterday, Nov. 18, was the first time in recorded history that the global 2m surface temperature breached 2.0°C above the 1850-1900 IPCC baseline. The long-term average remains below 1.5°C. But not for long.

No relief in sight. Day after day in range 45-50C, even 10 days out. That's 113-122F. These are temperatures that kill. Pakistan and NW India are being hit hardest, but it is brutal throughout most of India. Although there is little reporting, the death toll must be staggering.

It finally happened, breaking 5 sigma, the same statistical threshold physicists used to prove the existence of the Higgs boson. At 2,700,000 km² below the 1991-2020 mean, Antarctic sea ice extent was 5.14σ below the mean, roughly a 1-in-7,400,000 chance.

Our favorite planet has now seen 20 days in a row breaking the modern-day record high-temperature of 16.924°C (62.46°F) set on July 24, 2022. This global heatwave is likely the hottest 20-day stretch in the last 100,000+ years.

Apologies in advance for not explaining this in any way, but here are the daily standard deviations for Antarctic sea ice extent for every day, 1989-2023, based on the 1991-2020 mean. Each blue line represents the SD's for a full year. Lighter is more recent. 2023 is in red.

Here we go again, a new record anomaly for North Atlantic sea surface temperatures. Today's anomaly is a full 1.15°C above the 1982-2023 mean for the day. I thought the previous peak was high, but I may need to extend the y-axis again soon! Data: climatereanalyzer.org/clim/sst_daily…

What's happening to Antarctic sea ice extent isn't getting enough global media attention. And by "enough" I mean none. Nothing. This ongoing and dramatic collapse is completely absent from today's news. Yesterday's sea ice extent was 4.02σ below the 1991-2023 mean (1-in-34,000).

Breaking news! Code FUBAR!!! Well, today is the day I have to extend the y-axis to accommodate a new record Global sea surface temperature of 21.21C. How is your day going?
