The advocates of global warming allege that all sorts of things will go bad because of global warming. They take that the earth will grow warmer as a given, ignoring data from the last 10 years. For example, they say that increasing damage in the South from Pine Beetles is due to global warming, despite evidence that the temperature of the southern US has been falling for 30 years. (This has been explained by the doomsters; it turns out that the declining temperature is due to increased CO2 combined with naturally occurring aerosols. That sort of confuses me.) That does not answer the question of how does the Pine Beetle know global warming is happening, and is spurred to more activity, if it is colder in the Pine Beetle's habitat? Now an English scientist named Muir has decided that global warming threatens to cause a cholera pandemic. The prominent French medical scientist Paul Reiter says the prediction is not credible.
