A lot has been written about the impact of global warming, but an article on ABC News discusses an aspect I had never thought about before. The article discusses the public health aspects of global warming. The article mentions a number of cases that can be directly or indirectly linked to global warming. For example, what was thought to be an outbreak of the Norfolk virus, on an Alaskan cruise ship, turned out to be due to “…a type of cholera-like bacteria, Vibrio parahaemolyticus…” How is this possible?
“There’s a sort of threshold level, above which concentrations of Vibrio in oysters become (accumulated) enough to cause illness in humans,” said McLaughlin, a medical epidemiologist with the Alaska Department of Health and Social Services in Anchorage. “That temperature is about 15 degrees Celsius. What we found was that 2004 was the first summer on record during which the temperature exceeded that.”
The article goes on to discuss insect borne diseases and asthma, among others. Definitely worth a read…
