An excerpt from

Averaged across the state of Georgia, the long-term annual temperature history shows that the first half of the 20th century was, in general, much warmer than the most recent 50 year period. Obviously, “global warming” has not had much of an effect on the temperatures here. While it is often reported that globally the last 10 years were the hottest on record, the story is much different in Georgia where only 1 of the 10 hottest years on record statewide occurred during the past 10 years. Four of the state’s 10 all-time hottest years, including the hottest year on record, occurred during the 1920s—more than 75 years ago. Further, while only 14 of the recent 50 years were above the long-term average, 38 of the first 50 years of the 20th century were warmer than average.
Also note this paragraph:
The two tropical diseases most commonly cited as spreading as a result of global warming, malaria and dengue fever, are not in fact “tropical” at all and thus are not as closely linked to climate as many people suggest. For example, malaria epidemics occurred as far north as Archangel, Russia, in the 1920s, and in the Netherlands. Malaria was common in most of the United States prior to the 1950s (Reiter, 1996). In fact, in the late 1800s, a period when it was demonstrably colder in the United States than it is today, malaria was endemic in most of the United States east of the Rocky Mountains—a region stretching from the Gulf Coast all the way up into Northern Minnesota—including the southern half of Georgia. In 1878, about 100,000 Americans were infected with malaria; about one-quarter of them died. By 1912, malaria was already being brought under control, yet persisted in the southeastern United States well into the 1940s. In fact, in 1946 the Congress created the Communicable Disease Center (the forerunner to the current U.S. Centers for Disease Control and Prevention) for the purpose of eradicating malaria from the regions of the U.S. where it continued to persist. The CDC was located in Atlanta, Georgia primarily because this region was the primary one which was still affected by the disease. By the mid-to-late 1950s, the Center had achieved its goal and malaria was effectively eradicated from the United States. This occurred not because of climate change, but because of technological and medical advances. Better anti-malaria drugs, air-conditioning, the use of screen doors and windows, and the elimination of urban overpopulation brought about by the development of suburbs and automobile commuting were largely responsible for the decline in malaria (Reiter, 1996; Reiter, 2001). Today, the mosquitoes that spread malaria are still widely present in the Unites States, but the transmission cycle has been disrupted and the pathogen leading to the disease is absent. Climate change is not involved.
