Thousands of diplomats, activists, journalists and lobbyists are gathering in the sweltering, tropical heat of Belém, at the mouth of the Amazon, for the Cop30 climate talks.

Since Brazil was awarded the hosting duties three years ago, hopes have been high that the Amazonian Cop – taking place in the country that hosted the Earth summit where the global fight for the climate first began – could be a turning point in the fight against climate breakdown.
