“My heart aches when I think of my village, my ancestors, my old days. I had no choice but to leave my birthplace.”

Now in Dhaka’s poor Mirpur area, living in a one-room hut raised over a swamp, Begum and Jewel may be away from the swelling Mehgna, but say they can’t adjust to the difficult city life.“We had a place of our own and didn’t have to pay any rent. Our monthly income was sufficient to run our family,” recalled Begum, referring to their life back in Ramdaspur.

“Now we are forced to pay home rent and spend such an amount of money for food that what we earn isn’t enough for the family,” she said.Arzu Begum stands by the door of her house in the poor Mirpur area of Dhaka, Bangladesh on July 3, 2022.

Her husband earns 12,000 takas ($136) a month by doing a “dirty job” going door-to-door and sorting household waste while Begum earns another 4,000 takas ($45) as a cleaner for two different houses. Her income pays the family’s rent and Jewel’s barely covers the rest of the family’s outgoings.Jewel, who used to catch fish in his village, says they lived there joyfully and thought of giving a better life to their children.

“I had a plan to raise my children properly, to send them to school. But now, everything is so uncertain that I don’t know how we would survive. My children are growing up but I cannot take care of them,” he said.

“My job is very dirty, I don’t feel good sorting out all the nasty stuff I collect from households in my wealthy neighborhood,” he added.EDITOR’S NOTE: This story is part of an ongoing series answering some of the most fundamental questions around climate change, the science behind it, the effects of a warming planet and how the world is addressing it.

There may be an uptick in climate-related policy, discussions and activism, but the science isn’t all that new.Scientists in the early 1800s began to recognize that some gasses and water vapor could trap heat in the atmosphere. And for the last sixty years, researchers could definitively measure that carbon dioxide levels in the atmosphere were rising, thanks to a

Meteorologists in the middle of the twentieth century also started to understand the climate as a “system that is dynamic, constantly changing, and perhaps also vulnerable to external forcing and alteration,” said Martin Mahony, a lecturer of human geography at the University of East Anglia who studies the history of climate science and its interactions with politics.Add to that the knowledge that CO2 levels were going up and scientists started realizing that this could be a major issue.
