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.
