In July of 2018, a devastating downpour in western Japan forced 2 million people to evacuate their homes. The changing environment is expected to cause more heat stress, an increase in waterborne diseases, poor air quality, and diseases transmitted by insects and rodents. The IPCC predicts that increases in global mean temperature of less than 1.8 to 5.4 degrees Fahrenheit (1 to 3 degrees Celsius) above 1990 levels will produce beneficial impacts in some regions and harmful ones in others. The potential future effects of global climate change include more frequent wildfires, longer periods of drought in some regions and an increase in the number, duration and intensity of tropical storms. As a result, the ocean is becoming more acidic, affecting marine life. We are already seeing changes in the distribution of some water-borne illnesses and disease vectors. It's created more extreme and frequent blizzards, heat waves, and other forms of extreme weather. Heat stress, droughts, and flooding events may lead to reductions in crop yields and livestock productivity. It is projected to rise another 1 to 8 feet by 2100. Many states and cities are beginning to incorporate climate change into their planning. By the end of this century, what have been once-in-20-year extreme heat days (one-day events) are projected to occur every two or three years over most of the nation. Decreased water availability will have economic and environmental impacts. The intensity, frequency and duration of North Atlantic hurricanes, as well as the frequency of the strongest (Category 4 and 5) hurricanes, have all increased since the early 1980s. The Arctic Ocean is expected to become essentially ice free in summer before mid-century. In some regions, particularly in the western United States, drought is an important factor affecting communities. Susan Callery That downpour is just one example of the climate pheno… Climate change is already prompting an increase in migration, with people being forced to leave their homes because of drought, flooding, and other climate-related disasters.
