Is there really a correlation between CO2 and cholera?

Risk of Disease Rises With Water Temperatures - washingtonpost.com

When a 1991 cholera outbreak that killed thousands in Peru was traced to plankton blooms fueled by warmer-than-usual coastal waters, linking disease outbreaks to epidemics was a new idea.

Now, scientists say, it is a near-certainty that global warming will drive significant increases in waterborne diseases around the world...

Cholera - Wikipedia, the free encyclopedia

* 1816-1826 - First cholera pandemic: Previously restricted, the pandemic began in Bengal, and then spread across India by 1820. The cholera outbreak extended as far as China and the Caspian Sea before receding.
* 1829-1851 - Second cholera pandemic reached Europe, London and Paris in 1832. In London, the disease claimed 6,536 victims; in Paris, 20,000 succumbed (out of a population of 650,000) with about 100,000 deaths in all of France.[19] The epidemic reached Russia (see Cholera Riots), Quebec, Ontario and New York in the same year and the Pacific coast of North America by 1834. [20]

* 1849 - Second major outbreak in Paris. In London, it was the worst outbreak in the city's history, claiming 14,137 lives, over twice as many as the 1832 outbreak. In 1849 cholera claimed 5,308 lives in the port city of Liverpool, England, and 1,834 in Hull, England.[19] An outbreak in North America took the life of former U.S. President James K. Polk. Cholera spread throughout the Mississippi river system killing over 4,500 in St. Louis[19] and over 3,000 in New Orleans[19] as well as thousands in New York.[19] In 1849 cholera was spread along the California and Oregon trail as hundreds died on their way to the California Gold Rush, Utah and Oregon.[19]
* 1852-1860 - Third cholera pandemic mainly affected Russia, with over a million deaths. In 1853-4, London's epidemic claimed 10,738 lives.
* 1854 - Outbreak of cholera in Chicago took the lives of 5.5% of the population (about 3,500 people)
