Brazil's newly nominated head of the planned 2025 COP30 climate summit in the Amazonian city of Belem warned on Tuesday that President Donald Trump's decision to withdraw the United States from the Paris Agreement would cast a shadow over the talks.

Brazil warned Tuesday that US President Donald Trump's decision to withdraw from the Paris climate agreement would have a major impact on COP30 talks to be held in the Amazon in November.
