Occasional Thoughts on Climate Change

Here are the temperature anomalies for the Nepal/Tibet area. If Copernicus confirms this data for August, that will raise questions about JB's maps. Perhaps, just as with the CFSv2, they have a cold bias?

Thanks, Don. Wow, this isn’t even close to the cold JB showed though it was unlabeled. Is he by chance using normals from the Eocene epoch?

I have never seen this type of real-time analysis map be +1.0 degrees C

Even when it is using the cooler 1981-2010 instead of the warmer 1991-2020 for climo?

I've been tracking since 2023. Over 1C daily is very warm but it has happened before mainly in the 23/24 nino. 1.04C in Nov 2023 is the highest monthly value. August was 0.942 the 5'th highest monthly value , the higher values were the last 4 months of 2023. Note that changes to the gfs model may change the metric.

Honestly I will say that I have not checked that specific map very often. It's not of particular interest, day to day, for me.

It seemed like some individual days in the 2016 El Nino were very high like +0.8C or something. For example, Feb 2016 is listed as +0.817C on that web site. The recently monthly anomaly values, like July and August 2026, are high (on that web site), +0.764C and +0.942C. So that's pretty insane.

Didn't even try, what's a few billion dead as long as the worst people on the planet keep getting richer

The level of cognitive dissonance on display from the snow lovers here still trying to wishcast a future as the planet burns is lol

Following the warmest August and warmest month on record in the ERA-5 dataset, September 1 started with a global mean temperature of 16.739C. That destroyed the monthly record of 16.607C from September 1, 2024. The preliminary 0.132C difference between the new mark and the old record is the largest difference between any first and second highest monthly values.
