Greta Thunberg’s endorsement lands Polish coal miner in hot water

A Polish coal mining union chided one of its leaders for meeting climate activist Greta Thunberg as a misstep that undermines their efforts to keep coal as the country’s key source of energy.

The meeting -- held in coal-dependent Poland earlier this month -- made it to the speech that Thunberg, 17, gave at the World Economic Forum in Davos on Tuesday. She accused the global leaders of giving up on the climate change fight.
