Editor's note

Wildfires in the Arctic are normal. But climate researcher Nancy Fresco says this year’s fires – stretching across Siberia, Greenland and Alaska – reflect worrying trends. She describes how frequent and intense wildfires, driven by warmer temperatures, are not only disrupting life for people in the regions, but also changing Arctic ecosystems and the cycles of regrowth scientists have seen in the past.

During his first term in office Nigeria’s President Muhammadu Buhari delayed announcing his ministerial appointees. His second term started with a similar delay. On both occasions Buhari claimed he was taking time to pick candidates whose reputations were not tainted by corruption. But this cabinet, like the last, includes a number of his political cronies who have been associated with graft allegations. Ini Dele-Adedeji argues that this means the next four years of Buhari’s government will be more of the same - and that’s bad news for Nigerians.
