Not all of the effects of climate change are bad. For example, climate change causes an elongated growing season, which isn't necessarily a bad thing. However, most of the effects of climate change WILL cause problems.
Climate change causes many chsnges in precipitation. In some areas, there has been and will be an increase in precipitaion, which can cause floods. This increase will occur in all regions of the U.S., but some regions will recieve a greater increase in precipitation than others.
Droughts and heat waves will become more intense accross the nation, and cold waves will become less intense. The temperatures in the summe will ontinue rising, which will cause te soil to dry out. This in turn will cause heat waves and droughts to become more intense.
"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[,]" (https://climate.nasa.gov/effects/). This means that as climate change gets worse, hurricanes will become more frequent, and therfore will be the cause of much more damage.
It is a well-known fact that climate change causes sea levels to rise. Why? Well, the increasing amount of CO2 in our atmosphere traps more and more heat in our atmosphere. This heat melts glaciers and other ice, including the polar ice caps, and melting these ice forms adds MUCH MORE WATER to our oceans. The sea level of our oceans has increased by 8 inches since 1980, and it is predicted to rise another 1-4 ft. by 2100. Additionally, warmer ocean water takes up more space, which also contributes to sea level rise. On top of all this, "the Arctic Ocean is expected to become essentially ice free in [the] summer before mid-century[,]" (https://climate.nasa.gov/effects/).
