Brazil's first lady, Janja Lula da Silva, swore at billionaire Elon Musk during a G20 social event on Saturday at which she spoke about the need to regulate social media to rein in misinformation.

The plea, made in a letter to G20 leaders from UN Framework Convention on Climate Change Executive Secretary Simon Stiell, comes as negotiators at the COP29 conference in Baku struggle in their negotiations for a deal intended to scale up money to address the worsening impacts of global warming.

Negotiations were deadlocked Saturday at the midway point of the UN climate summit, with hopes pinned on G20 leaders intervening to strike a critical finance pact at the crunch talks. After nearly a week of bargaining in Azerbaijan, nations were no closer to agreeing a $1 trillion deal for climate-action investments in developing nations.

Half way through the UN climate conference in Baku, the UN climate chief looked ahead to the gathering of the Group of 20 (G20) powers next week and issued a dire warning about the outlook for the globe unless changes are made.
