Not everyone was a fan of climate activist Greta Thunbergs passionate speech at the World Economic Forum in Davos earlier this week.
On Thursday, U.S. Treasury Secretary Steven Mnuchin chided the 17-year old climate activist and her demand for a complete divestment from the fossil fuel industry with the stock answer of choice for every adult whos found themselves debating a teenager. Is she the chief economist or who is she? Im confused, Mnuchin said, then clarifying that it was a joke that was funny.
After she goes and studies economics in college she can come back and explain that to us, Mnuchin continued, according to CNBC.
Thunberg later responded on Twitter without directly mentioning Mnuchin by name.

My gap year ends in August, but it doesnt take a college degree in economics to realize that our remaining 1.5 degrees Celsius carbon budget and ongoing fossil fuel subsidies and investments dont add up, Thunberg wrote, alongside a graph showing rising emission levels.
So either you tell us how to achieve this mitigation or explain to future generations and those already affected by the climate emergency why we should abandon our climate commitments the young activist continued.
Thunberg made the call for fossil fuel divestment as well as an end to subsidies, exploration, and extraction in remarks she gave at the World Economic Forum earlier this week. We dont want these things done by 2050, 2030 or even 2021, Thunberg said. We want this done now.

Thunbergs tussle with Mnuchin wasnt her first with the Trump administration this week. During his own Davos speech on Tuesday, President Donald Trump called climate activists and scientists perennial prophets of doom, and said it was not a time for pessimism. (Trump also called Thunberg very angry in an interview with the Wall Street Journal prior to his Davos appearance.)
Later that day in her speech, Thunberg didnt mention Trump by name but paraphrased his earlier remarks. You say children shouldnt worry. You say: Just leave this to us. We will fix this, we promise we wont let you down. Dont be so pessimistic, Thunberg said.
And then, nothing. Silence, she continued. Or something worse than silence. Empty words and promises which give the impression that sufficient action is being taken.
On Thursday, the Bulletin of the Atomic Scientists moved its doomsday clock to 100 seconds to midnight, largely due to the simultaneous existential dangers of climate change and nuclear war.
If decision makers continue to fail to act citizens around the world should rightfully echo the words of climate activist @GretaThunberg and ask: How dare you? Bulletin CEO Rachel Bronson said.
