There is a new version of the PIOMAS model. It shows the anomaly trend is less negative than the previous model suggested. I don't know the reason for this, but perhaps someone here does and could write a post about it before Watts finds out about this.

Look here:

Or, to comare with the previous model:

I guess this article expains it.

Daniel, suggest you post in the general chat forum in future. It's where most people hang out and comment. A lot of other sections get ignored - just the way it is.

Trend is greater with the adjustment.

Robert, I think you should compare these two images. The top one is the graph currently displayed on the PIOMAS page. The bottom one is the version 2 graph.

Here is what the data actually looks like when smoothed over 365 days.

Rob, do you have the actual numerical data? All I've ever been able to find is the volume anomaly trend graph.
