I was reading through that, waiting for them to mention marine fuel (which they do). Cleaner fuel is causing less cloud cover, so we’ve been accidentally geoengineering a cooler climate for a while - until we “fixed” it in 2020.
I read/watched something a few years back arguing that we should shoot sea water into the air from cargo ships to restore this beneficial effect.
I decided on Symfonium as well - especially once I realised the author, Tolriq, was the same on who’d made Yatse, my favourite Kodi remote. Tolriq is an indie developer and always has very fair pricing and excellent support, so I’m happy to pay (once, per app) for a polished experience.
