A study by researchers from MIT and the Swiss Federal Institute of Technology in Zurich shows that rainfall could increase by 3 to 15 percent for every degree Celsius the planet warms. If the average global temperatures rise by 4 degrees over the next hundred years because of increased carbon dioxide emissions, the U.S. and Europe could experience increased rainfall. Some areas will experience increased rainfall while other places will see a decrease in rainfall such as around the subtropical oceans. This increase in average rainfall would bring the question of how to update the building codes so structures can adapt to the higher risks of flooding that will impact many living in coastal areas, according to the article. For the last 25 years scientists have predicted, based on climate models, that the intensity of rainfall will increase. This information came from 22 models based on different areas from all around the world and all of the predictions showed that the highest increase in extreme rainfall will occur over parts of the Asian monsoon region.
Even without climate change, large numbers of people around the world still face the threat of famine. And climate change may be the one factor that makes things worse. In poor African countries, the food supply in those countries is already in a precarious state. For most
