"Although malaria was eradicated from the United States in the early 1950s, it had once been a prevalent disease, especially prior to the 1880s. Through-out the nineteenth century, malaria affected most populated regions in the United States, significantly undermining the health of the population and the U.S. economy. Above all, malaria was one of the country’s leading causes of death. According to the U.S. Census Bureau, 45.7 out of every 1,000 deaths resulted from malarial fevers in 1850."
It was (and is) controlled by draining swamps and getting rid of standing water, the use of insecticides and window screens. If malaria can be controlled today in Florida, I think most of the rest of the country doesn't need to worry about mosquito death pills for quite a while.
The greenhouse effect is most noticeable in the coldest parts of the greenhouse, like putting a lid on food in the microwave to spread the warming effect. The most impacted places will be furthest from the equator, which is why glacial melt is so prominent already. It's the canary in the coal mine. Once all that ice is lost, the climate patterns we know and can predict may and likely will change and be irriversible. There may be some local good effects, like farming in VA, but extreme heat/cold storms or tropical pestilence may negate any farm yield. Climate science is way more interconnected than we can wrap our heads around. The second third and 100th order derivates are unpredictable.
