Bill Gates has reignited debate over a climate agenda that prioritizes emissions cuts over the immediate needs of countries already facing deadly climate impacts.
Fossil fuel emissions have hit a record high while many nations have done too little to avert deadly global heating.
After the International Court of Justice declared that countries have a legal duty to curb greenhouse gas emissions, Pacific Island advocates are heading to COP30 to demand that world leaders phase out fossil fuels, fund recovery from climate disasters, and center Indigenous voices in climate decisions.
