Much as I hate the direction of travel here, these pledges are largely 🐂💩. Local to me Eastleigh set a target of 2025 in 2019. Did they meet it? Get close? Here's the most recent GHG report so I assume not. Approved the airport expansion in 2021 (although technically not "their" emissions) 🤷
I am struggling to think of a more inaccurate adjective for coal than "clean". It might have powered the industrial revolution and been at the heart of mining communities, but it's filthy stuff, even before you burn it.
Compare with NHS advice on vaccines 👇 So strange to see the US government losing its way so badly.
Oh, and for the "Europe has more deaths from high temperatures than America has from guns" crowd, here is some data you can actually compare. ourworldindata.org/grapher/temp...
This is the chart everyone needs to see alongside excess mortality figures for heatwaves. In the UK, for example, far more people die from temperatures of 5-15°C than above 25°C. 5/6
That is poor evidence in support of your point. PISA scores for science have paralleled the OECD average. Even if you choose to ignore that, the decline started with children beginning secondary school before the 2010 election and certainly well before Gove's NC and GCSE changes.
... this is partly because it's so badly specified. I mean, look at this 👇. Does this mean I-V and R-T graphs, particle model explanations, just "thermistor resistance changes with T", or something else? #iTeachPhysics
However, the manual for Casio fx-991CW has only this, which could mean anything but might mean it is a piece of crap that only a mathematician could love ;-)
Actually, seen your profile so I'm going to assume you're using x10^x and not y^n (like most students do when you get hold of them after GCSE). I have a Casio fx-85GT and it defaults to that button working how it should but you can change the setting. Manual 👇
People in their 60s are about 10 times safer drivers than people in their 20s. People in their 70s at least 3 times safer. Older than that and they barely drive at all.
How about this for an interesting poll. Not sure how much it's properly weighted, but even so. From @roadscholar.bsky.social limbostructure.substack.com/p/making-bri...
The number and trend in NEETs is a real concern, but it's important to remember it's not new.
This does imply the late 1990s figure in the Timpson report was pretty much a peak. There may be holes in that data but I think it is unlikely that PX rates now are 1/3 of the 1990s rate. They probably were around 2012/13/14, but they're more like 2/3 of the 1990s rate now.
This report goes back slightly further. assets.publishing.service.gov.uk/media/5a7a3d...
After Covid we've fairly strong evidence behaviour in schools got more difficult and PX rate increased, although not massively. PX rate now reported termly, so the PX rate on this graph is more like 0.04/term just before Covid, peaks 2023/24 at 0.05/term.
After Timpson, PX rate was flat at around 0.10 until Covid. explore-education-statistics.service.gov.uk/find-statist...
Timpson report data goes back to 1997-98. www.gov.uk/government/c... PX rate 0.16 in 1997/98.
@profbeckyallen.bsky.social is writing some remarkably good stuff about curriculum. profbeckyallen.substack.com/p/the-curric... This bit definitely captures a problem we've got in science at the moment.
Yes, sure, absolutely no-one has ever retired from the UK to go and live in France.
I get why it's 72 not 70, but if you're dividing by 10 and 7... ¯\_(ツ)_/¯
Even more dramatic just how much of a problem younger drivers are if you look at the absolute data, because older drivers do fewer miles.
Okay. Post about younger drivers: Mile for mile, drivers in their early 80s are substantially safer than drivers in their 20s. This is UK.
