We return now to the COP 26 climate change conference in Glasgow, Scotland,where leaders are trying to reach new agreements and commitments toward reducing emissions and slowing the impacts of global warming.William Brangham is there for us all week.In his report tonight, he looks at key questions about getting enough help to the world's most vulnerable nations.On the bustling streets of Dhaka, Mohammad Nirob is part of what's becoming the biggest migration inside Bangladesh.Seven years ago, the 45-year-old had to leave his wife and four kids behind in their village over 100 miles away to come here and earn money.Why? His prior life and livelihood had been washed away by ever-increasing floods, ones that are getting worse in a warming world.I had run a business before. But the business is no more now.The shops, the houses have been devoured by the river.For more than half the year, our house was submerged two to three times a month.When the high tide happened and the river water flowed into our house, it restricted our movements, our lives.Climate refugees like Nirob are partly why Dhaka is one of the fastest growing cities in the worldand why Bangladesh represents one of the great cruelties of climate change.Those that have done little to cause the problem are paying the biggest price.
