Last year Lewis Gordon Pugh completed the coldest swim in history. He swam 1 km in the southern ocean. Near the coast of Antarctica. The water there is very cold 0°C. The water at your local swimming pool is probably about 27°. The cold water wasn’t his only problem. The southern ocean is also the home of the leopard seals. They’re big, fast and dangerous. They normally eat penguins. So Lewis made sure that there were no penguins near him. Lewis has also swam at the other end of the world in the icy waters of the Arctic Ocean. Why does he do it? He wants to make people aware of global warming. We can see the effects of global warming very clearly in the Arctic and Antarctic, he says. Because a lot of the ice has gone. Lewis hasn’t finished swimming. Next year, he’s going back to swim in the Arctic Ocean again.
