Hi @garethsjones.bsky.social, I'm not sure I ever thanked you for allowing me to show your lovely HadCM3 runs (although they weren't actually on the floor of the Tate Modern, there was just a bit of gaffer tape). Anyway, 20 years on, thanks dude!!

Thanks, @stottpeter.bsky.social! As you know, that graph projected onto the floor of the Tate Modern came from you and your group at the @metoffice.gov.uk (especially Gareth Jones, if I remember rightly). So it was "graphs like yours" that convinced David Attenborough about climate change.

Climate modelling work (e.g. GeoMIP) suggests that SRM geoengineering could work as a temporary/emergency way to cool the climate. This certainly does not justify large-scale implementation at this stage. However, open research on SRM needs to be encouraged, not driven underground.

10% GDP boost to Global South from clean energy transition
