Leaders pledge to act for climate after Greta Thunberg's emotional speech

She had earlier given a speech in the United Nations on Monday in which she scolded for doing little. Following this, leader after leader promised to do more to prevent a warming world from reaching even more dangerous levels. As they made their pledges at the Climate Action Summit, though, they and others conceded it was not enough. And even before they spoke, teenage climate activist Greta Thunberg shamed them over and over for their inaction: "How dare you?"

Secretary-General Antonio Guterres concluded the summit by listing 77 countries that committed to carbon neutrality by 2050, 70 nations pledging to do more to fight climate change, with 100 business leaders promising to join the green economy and one-third of the global banking sector signing up to green goals. "Action by action, the tide is turning," he said. "But we have a long way to go."

Businesses and charity pledge support for climate change

Businesses and charities also got in on the act, at times even going bigger than major nations. Microsoft founder Bill Gates announced Monday that his foundation, along with The World Bank and some European governments, would provide $790 million in financial help to 300 million of the world's small farmers adapt to climate change. The Gates foundation pledged $310 million of that. "The world can still prevent the absolute worst effects of climate change by reducing greenhouse gas emissions and developing new technologies and sources of energy," Gates said. "But the effects of rising temperatures are already under way." As the day went on Monday and the promises kept coming, the United States seemed out in the cold.

Greta Thunberg 'scolds' world leaders for empty words

Before world leaders made their promises in three-minute speeches, the 16-year-old Thunberg gave an emotional appeal in which she scolded the leaders with her repeated phrase, "How dare you." "This is all wrong. I shouldn't be up here," said Thunberg, who began a lone protest outside the Swedish parliament more than a year ago that culminated in Friday's global climate strikes. "I should be back in school on the other side of the ocean. Yet you have come to us young people for hope. How dare you. You have stolen my dreams and my childhood with your empty words."

"We are in the beginning of a mass extinction and yet all you can talk about is money," Thunberg said. "You are failing us."
Later, she and 15 other youth activists filed a formal complaint with an arm of the U.N. that protects children, saying that governments' lack of action on warming is violating their basic rights. U.S. President Donald Trump mocked Thunberg on Twitter, writing: "She seems like a very happy young girl looking forward to a bright and wonderful future. So nice to see!"
