The 30th UN Climate Change Conference in Belem, Brazil, is taking place against the backdrop of a major pushback against climate action. The United States has withdrawn from the Paris Agreement. The European Union has diluted its 2040 climate target. Some of the world’s largest banks—J.P. Morgan, Bank of America, and Morgan Stanley—have walked away from their net-zero alliances. Even Bill Gates, a champion of climate innovation, now argues that the world should prioritise health and development over climate goals—ignoring that prosperity and public health depend on a stable climate.
