Argentina has withdrawn its delegation from the COP29 climate summit in Baku, Azerbaijan, on orders from President Javier Milei, raising concerns about the stability of the Paris Agreement. This decision, confirmed by Ana Lamas, Argentina's undersecretary for the environment, follows Milei's past claims that the climate crisis is a 'socialist lie' and previous threats to exit the Paris Agreement, although he has since retreated from that position. The withdrawal comes shortly after Milei's conversation with US President-elect Donald Trump, who has expressed intentions to pull the US out of the Paris Agreement once more. This move by Argentina, traditionally an active participant in climate negotiations, has sparked anxiety about potential ripple effects, emboldening other nations to reconsider their commitments. Brazil, in contrast, has updated its climate targets, committing to a significant reduction in emissions by 2035. The departure of Argentina, coupled with Trump's electoral promises, poses a potential threat to global climate efforts.
