US philanthropists vow to raise millions for climate activists

Fund donates 500,000 to grassroots Extinction Rebellion and other groups, with promise of more to come

A group of wealthy US philanthropists and investors have donated almost half a million pounds to support the grassroots movement Extinction Rebellion and school strike groups - with the promise of tens of millions more in the months ahead.

Trevor Neilson, an investor and philanthropist who has worked with some of the world's richest families, has teamed up with Rory Kennedy - daughter of Robert Kennedy - and Aileen Getty, whose family wealth comes from the oil industry, to launch the Climate Emergency Fund.
