This morning at Broadbeach.
Desmos, Geogebra, JSXGraph and Wolfram|Alpha are excellent graph plotters when the domain and range is limited, but can fall over for various "challenge" plots when the domain or range is extended. My ASVG plots are more successful, but are not generalised. See bourne2learn.com/math/asvg/as...

The UK took its Kyoto agreements more seriously than most, and will reach 0% fossil fuels by around 2090 at the current rate. (This is better than the world average which is over 200 years to get to zero carbon.)

"Solastalgia" is the term used to describe the grief felt when coming across environmental destruction.
This used to be a nature corridor of sorts at the end of my street. Now it's a bare, hot wasteland set to become a 4-lane motorway.
Madness.
