Born when co2 was 320ppm. It's now 423ppm :( bicycle as primary transport Brompton & mountain bike & mountain e-bike. unix/linux sysadmin, more ops than dev. Bookish. Concerned about AGW, biome, enshittification

This folks is the coolest Summer you will ever experience again
As parts of America sizzle under a heat dome
Southern Europe is frying too with Turkey setting a new record of over 50 C (122 F)
These temperatures will kill you if you stay out too long outside and if you have no air conditioning

Killing the only planet known to harbor life at ever faster rate

Little more than half a year into 2025, mankind has already hit Earth Overshoot Day, consuming resources at a rate that far outpaces the capacity to restore them.

Will this be the last Keeling curve upate from NOAA for CO2 at Mauna Loa?

June 2025: 429.61 ppm

This may be a tragic moment:

A lot of media are covering Europe’s heatwave πŸ”₯ but few are connecting it to the climate crisis.

Tools like the Climate Shift Index show this heatwave is up to 5x 😱 more likely because of climate change. That context matters.

The CERES data are shown from 2001 to 2023. The CMIP6 data are shown from 2000 to 2030. All EEI are given as 12-month running means. CMIP6 model mean is shown by a thick black line and individual models are shown in thin gray lines. Only one ensemble member for each of the models is shown.

Data from CERES show that from 2001 to 2023, Earth absorbed more energy than any CMIP6 model predicted.

Models with ECS < 2.5Β°C fail to match observed LW & SW trends (LW↓, SW↑). This means future warming may be closer to higher-sensitivity projections.

The drought in Europe is bound to cause food shortages as it continues unabated. I wonder whether mankind will wake up & smell the coffee, whilst coffee still exists.

Europeans are kept completely oblivious about the rate of summer warming.

Gross negligence from those responsible to keep us informed and safe.

Seems important:

All ('IPCC') CMIP6 models are completely unable to reproduce what NASA satellites observed!

The rate of global warming (starting with Earth's Energy Imbalance and now surface air temperature) has more than doubled!

COβ‚‚ at Mauna Loa just reached a monthly average of >430 ppm for the first time.

That's possibly higher than in over 3.3 million years.

The global RATE of increase is off the chart.

It's hard to exaggerate how unprecedented this is!

Cartoon entitled "Road Positioning" and subtitled "Times when it might be safer to cycle in the middle of the lane". There are four illustrated examples

1. Approaching road narrowings where it would be unsafe for drivers to overtake e.g. traffic islands etc

2. In slower-moving traffic. Keeps you visible. You can move over to the left again if the traffic speeds up.

3. Where there are parked cars and a car door might be opened.

4. On quiet roads. Keeps you away from various hazards found in the gutter.

People who cycle are often accused of cycling "in the middle of the road".

What they really mean of course is cycling in the middle of the lane, and there are lots of good reasons why people do this, explained succinctly in this @davewalker.bsky.social cartoon for @cyclinguk.bsky.social

Quite possibly the biggest climate story of the year (especially when we look back on this in a few years' time)

For the first time on record, China's emissions are falling due to clean energy growth, not slow power demand...

Just your regular reminder of where global CO2 emissions are tracking compared to scenarios that keep warming to below 1.5C in 2100, with "no or low overshoot" (maximum temperature around 1.6C).

Accounts with that in their profile, to me indicate how lazy/careless they are and it helps to determine whether they're worth listening to.
