Climate change is disrupting natural ecosystems in a way that is making life better for infectious diseases and scientists believe that just a one- or two-degree change in temperature can lead to disease outbreaks. It is very reasonable because they also found some pathogens reproduce more often in warmer temperatures, so there are more germs around to cause infection.

The author warns that malaria and yellow fever may become more common as milder winters permit the seasonal survival of more mosquitoes, which carry these diseases and climate warming could enable them to move into areas where the cold once kept them out. Also we can meet in the last part of the article some examples of effects occurred.
