Climate change hits the poorest hardest

Research shows that rising temperatures pose a greater risk of illness and death, as Hong Tsang reports from Hong Kong.

It was the flu that made Jordan Lee, 10, miss an important final-term exam. The night of Nov 12 was a nightmare. When Lee's temperature hit 40 C and stayed there, he was admitted to Caritas Medical Centre in Hong Kong and remained there until the fever abated.

The boy is always ill. His mother, who would only give her name as Ms Tao, quickly realized that after she and Jordan moved into a cramped, poorly ventilated apartment in Sham Shui Po, Kowloon, five years ago. Lee has been in poor health ever since.
