In the article, “First warmer, then sicker,” there are some examples of the results of global warming. “Incremental temperature changes have begun to redraw the distribution of bacteria, insects and plants, exposing new populations to diseases that they have never seen before.” In Sweden, global warming has increased the “cases of tick-borne encephalitis since 1980s.” In Africa, it increased the area where mosquitoes can inhabit in Mt. Kenya, “bringing malaria to high villages that had never been exposed before.” On the other hand, global warming “helped reduce some diseases related to cold weather.” “One British study found that the number of children infected with a cold-like virus known as respiratory syncytial virus has been declining with warming temperature.” Moreover, according to the study by University College London, “each increase of 1.8 degrees clipped three weeks off the end the virus’ winter season.” That is, global warming causes some disease, but it also decreases the virus’ winter season and the number of some other diseases.
Global warming has a lot to do with biology. According to the book, “Essential Biology with Physiology,” the definition of biology is “the scientific study of life”, and global warming has affected biological life a lot. For example, the aforementioned fact about redrawing the distribution of creatures will make big impact on biological life on Earth.” Although global warming has helped reduce some diseases related to cold weather, it can harm biological life more as evident on the malaria exposure brought on by mosquito inhabitance in Mt.Kenya. According to the article, “The Role of Climatic Change in the Evolution of Mammals,” if climate changes “so fast that evolutionary adaptations simply cannot keep up… the fate for populations that experience such an effect is extinction.” That is, global warming probably adversely affects biodiversity on the earth. “Extinctions may so far outweigh evolutionary additions to...
