Log – 2025 December – Update

Updated °C Milestones – From First Appearance to Permanence with the 2025 data

Added update to Errata page. Minor typo in Warming Tapestry , and I’m a bit suspicious of the +0.71C number in Global Warming Baseline Adjustments for Nasa GISS data.

Log – 2025 December – Update to Spiral Warming

Updated Spiral of Global Heat with the latest data (up to mid December 2025) and posted to BlueSky.

Log – 2025 November – CO2 (ppm), Warming Stripes, Conferences

CO2 – Global Warming Stripes – Conferences – Following a request on BlueSky from Tadzio Mueller (requested out to the internet in general), I made an update to this classic graphic.

Log – 2025 November – Longest Running Average

To mark the 3-year-running average crossing 1.5C (Copernicus and Berkeley Earth data), I added Longest Running Average graphic, which shows what the longest running average is for 1.5C on any date, and also for other global warming milestones

I have been posting updates to the other graphs over the year. E.g.

Log – 2024 October – Move to Loess Smoothing

While comparing my work to that of others, I started to notice that “Loess” was a popular smoothing technique. I had come up with my own smoothing technique which wasn’t ideal and wasn’t great at the start/end of the trend line. Also I was labelling it pretty poorly.

I have updated all the graphics and analysis to use Loess (with a 30 year window of data).

See post: Improved Smoothing Function – Loess – which points to the older graphs
