Activists at COP26 tell the rich world to get its head out of the sand and keep its promises on climate change. Africa is paying an outsized price for pollution by developed nations. Also, Covid-19 has kept the border between DR Congo and the Republic of Congo closed for a year and a half. Those who depend financially on inter-country travel are barely hanging on.

As climate change continues to take effect, we are all going to have to change the way we behave in order to survive. That's the conclusion of Eric Klinenberg, a professor of social science at New York University who's written a book focusing on the extreme 1995 heatwave in Chicago. Temperatures there hit over 41°C, killing hundreds of people. Klinenberg says it's not just infrastructure that will have to change, but the whole way we interact with our families and those living around us.
