@russvought "alarmism"? Curious - because all of their predictions have come true so far.

@scotslassnow Ooof! Let me know if you get into the 940s!

Monitoring UK observations feed.
Lowest sea level pressure I could see is 948 hPa, Kinloss, Scotland.
Exceptionally low pressure.

I believe this ties #StormÉowyn with the notorious UK Great Storm of 1987 in terms of pressure intensity.

@PDAcortex @PhysInHistory Write that up then - with the calculations which show that TSI (assume you know what that is) is forcing DT.

Cheers.

[Dr. Craig Wallace @craigwallace]

@sterlingwalker @PDAcortex @PhysInHistory "It’s been written up."

with radiative balance calculations showing something other than carbon raising the temperature?

Definitely send me that paper. That will be enormous news.

[Dr. Craig Wallace @craigwallace]

@Ceist8 @PDAcortex @PhysInHistory Exactly this.

[Dr. Craig Wallace @craigwallace]

@PDAcortex @PhysInHistory "scientific consensus is irrelevant"

It is - when there is the emergence of a new theory that disproves the present one.

If you have one, you should definitely write it up asap.

LATEST sweep of global T:
Spt 2023:
HadCRUT5: +1.63°C above pre-industrial.
[ ^ 7th month in record to >1.5°C ]
NOAAGlobalTempV5.1: +1.59°C above pre-industrial.

5/5 Individual months in exceedance of 1.5°C are not a breach of the UNFCC Paris Agreement which requires a multi-annual sequence of >1.5°C to demonstrate a clear non-natural cause, but indicate our proximity to the threshold.

[Dr. Craig Wallace @craigwallace]

1/n Diagnosing individual, continuing, months in exceedance of 1.5°C is, naturally, sensitive to each month's pre-industrial value (nominally 1850-1900). These values differ, evidently substantially, between major datasets as a result of constituent data & assemblage techniques..

[Dr. Craig Wallace @craigwallace]

4/n This 'seasonality of discrepancy' will apply to all future years, unless re-versioning of either data effects the early records. The larger discrepancy within NOAAGlobalTV5 most likely attributable to use of ERSST for marine temperatures as opposed to HadSST4.

[Dr. Craig Wallace @craigwallace]

@RHarrabin This is an excellent overview of precisely that point: https://t.co/s0ZvAAQiZr

[Dr. Craig Wallace @craigwallace]

4/n To be clear: both records indicate numerous individual months that have been hotter, by >1.5°C, than their corresponding monthly pre-industrial average.

[Dr. Craig Wallace @craigwallace]

1/n The monthly 1.5°C breaches identified in HadCRUT5, relative to 1850-1900, are corroborated by the Berkely Land/Ocean Temperature Record. In fact the breaches are stronger, and more numerous, in BEST:
