Climate change is the human thumb on the scale, pushing us toward disaster. It is not a distant danger — it is already with us. As we continue to burn fossil fuels, its effects will only grow.
Some years ago I worked in Nigeria, helping to find peaceful solutions to conflicts. Its capital city, Lagos — one of the world’s megacities, with a population estimated at 14 million to 21 million — will most likely experience a sea-level rise of around 35 inches in the next few decades if current warming trends continue.
Even in this best-case scenario, which depends on the global community’s sticking to the Paris climate change agreement, many of the shops I visited and homes I passed during my years in the country will be flooded. The rising waters are already changingways of life and pressuring people to leave their homes. In the coming years, experts predict that millions of peoplein Lagos will be forced to move.
