The incredible tragedy for #ArcticScience of NOAA shutting down their #methane monitoring data. 5th May 2025 is the last data we'll ever get.

โpersisting with an inadequate fees-led model of higher education, in which universities are run as competing businesses funded by student consumers, is producing a dystopian academic landscapeโ

A bowl of red berries. Little red round ones are Chilean guava berries and the others are the last of the seasonโs raspberries.
Red Chilean guava berries happily growing on the little shrubs at my allotment
Harvested our precious minute crop of Chilean guava berries this weekend.
Little red balls that are somewhere between a strawberry and herbal tea in taste.
Apparently Queen Victoriaโs favourite berry that she had shipped in from her private stash garden in Cornwall.
So for-profit AI companies have trained on the world's largest collaborative volunteer project and a precious free resource, to make money for their for-profit enterprises. They have crushed traffic to the volunteer project, starving it of donors and volunteers

Globally averaged CO2 concentration (a) and its growth rate (b) from 1984 to 2024. Increases in successive annual means are shown as the shaded columns in (b). The red line in (a) is the monthly mean with the seasonal variation removed; the blue dots and blue line in (a) depict the monthly averages. Observations from 179 stations were used for this analysis.
Holy wow, +3.5 ppm COโ last year, up from +2.4 ppm average the past decade, and +0.6 ppm in the 1960s.
It gets scarier the closer you look at it. All this is a stress test for the planet, and it's buckling.
Two big reasons for the massive increase: wildfires, and the ocean sinks are shutting down.
Plug-in hybrid electric vehicles (PHEVs) pump out 5 times more planet-heating pollution than official figures show.
Running costs understated.
PHEVs emit just 19% less CO2 than petrol/diesel cars
Underestimate of emissions lets carmakers avoid fines.
Why do govts not corroborate industry claims?
We need mitigation AND adaptation.
Global warming impacts are already evident in the UK, and will definitely worsen in the coming decades even under the most optimistic scenarios.

Remember you know sooo much more than them so itโs not like a conference talk to your peers. I find it calms nerves to be reminded of this.
Speak slowly and repeat yourself often to consolidate knowledge (and to help those that daydream and missed it the first time ๐).
Have fun ๐คฉ

View out over Ryanโs field near the Hayle estuary on a quiet Sunday morning. Blue sky breaking through the cloud.
A lone spoonbill (centre) foraging amidst a whole heap of gulls (mostly herring and greater black backed), and a few ducks.
A beautiful lapwing (one of my favourite waders) on the water with ducks, gulls and a redshank in the background.
Nothing nicer than an early morning trip to Hayle estuary with a friend. So many amazing birds! ๐ฆ
