Mass migration from Africa to Europe will accelerate unless more is done to tackle climate change, naturalist Sir David Attenborough has told attendees at the International Monetary Fund (IMF) spring meeting in Washington, reports the Times. The paper quotes Attenborough on the link between migration and warming saying: “It is happening in Europe. People are coming from Africa because they can’t live where they are. If things go so more parts of the world become uninhabitable, that’s what will happen.” The Guardian also covers his speech, quoting him saying: “I find it hard to exaggerate the peril. This is the new extinction and we are half way through it. We are in terrible, terrible trouble and the longer we wait to do something about it the worse it is going to get.” Separately, Reuters reports that UK chancellor Philip Hammond told the IMF on Thursday he would use meetings in Washington this week to “urge fellow international policymakers to find ways to achieve sustainable economic growth and tackle climate change”. Hammond called on world leaders to put climate change and sustainable growth at the centre of their economic strategies, reports BusinessGreen. Meanwhile, the Washington Post carries an interview with Attenborough, under a headline that says he is now “talking about climate change like never before”. Attenborough tells the paper the US reversal on climate change policy is “a big blow” that makes it “more and more urgent that we keep going”. He also endorses the youth climate strikes, saying: “You don’t solve anything by striking. But you do change opinion, and you do change politicians’ opinions. And that’s why strikes are worthwhile.”
