Follow the conversation...What does that have to do with the OP? Indirectly it does, climate change, changes everything including bacteril behaviors, usually becoming more virulent.
We know insect behavior is very much affected by atmospheric conditions, and so is bacterial behavior.
Climate cange is only the second most dangerous threat to humanity.
Number one is the soaring scale of antibiotic resistance.
Deaths due to antibiotic resistance each year in the US: 35,000
Deaths due to cancer: 600,000
Deaths due to heart disease: 650,000
Not that it isn't a problem - but it's got a ways to go to become even the #2 killer.
Virus have nothing to do with antibiotics.Not necessarily.
An exponentially growing respiratory system contagion with no adequate medical treatment can cross the tipping point from invisible to single greatest cause of mortality in a few days. How far - that measure - this virus is from its tipping point to plague is not known, and may change at any time (mutations being frequent in these kinds of infections, while selection pressure is nearly ideal for its rapid evolution in places like the US that 1) lack key features of modern public health setups 2) have a mobile population. (The snowbirds are packing for their northern migration from the coastal States and busy southern ports even now).
As far as thread relevance - a plague virus will surely and significantly interfere with the kinds of deliberate efforts a response to AGW would require. But it may reduce CO2 output, and slow AGW down - plagues in the past seem to have delayed or reduced the effects of agriculture and other aspects of civilization on climate worldwide, simply by destroying the agriculture and those other aspects. This one would have to kill more people to bring the same benefit, but that's not impossible.
