Javier Milei, a right-wing politician and presidential candidate in Argentina, is known for denying climate change and promoting a radical neoliberal agenda. His political rise has been supported by the Atlas Network, a U.S. nonprofit that fosters free-market think tanks globally. Milei's economic proposals include reducing government ministries, cutting public spending, and dollarizing the economy. The Atlas Network has influenced Latin American politics by funding think tanks that share strategies and ideologies. Milei's connections to these think tanks have helped him disseminate his ideas and gain significant support, as evidenced by his lead in Argentina's primary election. Despite his climate change denialism, the topic was not a primary focus in the primaries, overshadowed by Argentina's food crisis. Milei's success represents a victory for the Atlas Network's ideals in Argentina.
