When the term "extinction" doesn't come up once in a one hour talk, you are not expecting it? Not ruling it out, but not likely? You are expecting severe social collapse and decline of populations but not necessarily an extinction event? I was monitoring wildlife. Mere collapse would be lovely.

Compare and contrast the Government language. £3,750 EV grant on a £35k car: ‘helping families’. Cycle to Work: ‘subsidising leisure’. And yet cycling delivers TEN TIMES the impact of electric cars for reaching net zero. It’s almost like narrative, not data, is driving policy.

🚨 None of the UN IPCC models capture what NASA satellites are seeing. We should assume and prepare for the worst, as there is a non-zero chance of 3°C of global warming by 2050. We better assume that it will happen and/or try to make sure that it doesn't happen. 1/

I just updated this NASA CERES graph. The regional level of Absorbed Solar Radiation increased by 4.2 W/m² in 20 years!! That's more than the global greenhouse gas forcing increase since 1750! The 2 W/m² Net Flux increase indicates that there is a lot more regional warming in the pipeline.

A lot of media are covering Europe’s heatwave 🔥 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. csi.climatecentral.org/climate-shif...

Data from CERES show that from 2001 to 2023, Earth absorbed more energy than any CMIP6 model predicted. Models with ECS < 2.5°C fail to match observed LW & SW trends (LW↓, SW↑). This means future warming may be closer to higher-sensitivity projections. doi.org/10.1126/scie...
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.

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
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.

This increase in Outgoing Longwave Raditation (0.75 W/m² in 20 years!) led many climate sceptics (some ill intended, many honestly and understandably confused) to doubt the role of greenhouse gases. Without the 0.85 W/m² greenhouse gas forcing increase, 1.6 W/m² would now be leaving Earth as OLR!
