Twenty-four people collapsed, and six were hospitalized from excessive heat at a Donald Trump rally in Las Vegas, where temperatures hit 40°C. A similar incident occurred days earlier in Phoenix. These events, reminiscent of India's election campaign grounds, highlight the 'Third Worldisation' of climate in the First World. Despite the heatwave in the US, Trump promoted more oil and gas extraction. European voters also prioritized economic concerns over environmental issues, even as heat and extreme weather increasingly affect traditionally temperate climates. Transnational efforts are essential to address these growing climate challenges.
