Some personal news: last week I became a German citizen! A typically understated, bureaucratic ceremony, but it still meant a lot to me. I’m looking forward to voting in my first German election, and shouting at people when they cycle on the Bürgersteig ;)

This has been a tumultuous week in Australian climate politics! And a good example of how target setting becomes a focal point for agenda-setting on climate, as per @jacobedenhofer.bsky.social, @chflachsland.bsky.social and my paper (below)

Bowen says cutting emissions by more than 70% ‘not achievable’ as 2035 target criticised from all sides
Albanese says 62% to 70% range represents ‘the sweet spot’ as Coalition rejects ‘economy wrecking’ target while Greens label it a ‘betrayal’
