The United States' financial chief on Thursday told Swedish teen Greta Thunberg to go study before calling for a fossil fuel halt, prompting the climate campaigner to reply it doesn't “take a degree” to understand the science.
The spat between US Treasury Secretary Steven Mnuchin and Thunberg again highlighted the tensions over climate change at the World Economic Forum (WEF) in Davos, where governments have come under pressure to act on global warming as well as talk about the issue.
German Chancellor Angela Merkel on Wednesday also said in a keynote address that governments were obliged to act on the younger generation's concerns over climate change.
Mnuchin had earlier advised Thunberg, who has been bitterly critical of US policy during her stay at Davos, to study economics before giving out lessons. Asked about the 17-year-old's demand for an immediate halt to investment in fossil fuels, he told reporters: After she goes and studies economics in college, she can come back and explain that to us.
But in a thread of tweets, Thunberg dismissed Mnuchin's comments in a typically withering response.
My gap year ends in August, but it doesn't take a college degree in economics to realize that our remaining 1.5 degrees carbon budget and ongoing fossil fuel subsidies and investments don't add up, she wrote.
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, she added.
In a speech on Tuesday, US President Donald Trump had castigated the prophets of doom and those that predicted a climate apocalypse, in comments widely seen as an attack on Thunberg who sat in the audience.
But either by accident or design, there was no meeting between Trump and Thunberg before the US leader left the Swiss ski resort on Wednesday declaring he would have loved to have met the climate activist, Time magazine's Person of the Year.
Thunberg at the forum had repeated her climate warnings in sometimes withering terms, hammering home in a speech that it was time to panic because the house is burning. Notably she had called for an immediate halt to investments in fossil fuel exploration and extraction and an end to fossil fuel subsidies.
