A new study shows that prevalence of kidney disease in workers exposed to high temperatures may be linked to a global increase in the number of heat waves caused by climate change . Researchers studied increases in chronic kidney disease among groups such as poor agricultural workers after an epidemic of such disease amongst male sugar cane workers in Central America was initially thought to be linked to chemicals or chemicals . However , higher levels of illness were discovered among cane cutters than amongst those applying pesticides . This suggested that the workers most at risk were those experiencing the most intense physical exertion and highest temperatures . Other epidemics are in Andhra Pradesh in India and also 100,000 rice workers in Sri Lanka . Global warming has increased temperatures overall by nearly 1 degree Celsius (just under 2 degrees Fahrenheit) over the past century, and they are expected to rise by another 3 to 4 degrees C by the end of this century, the authors write. Workers in Africa and the Middle East may also be at risk .
