TITLE=ENVIRONMENT REPORT - Effects of Climate Change in the United¹ States BYLINE=Cynthia Kirk

（Start at 59" ）This is Bill White with the VOA Special English ENVIRONMENT REPORT.
Government researchers in the United States say climate change could have serious health effects for Americans. They say hot weather may cause more health problems, such as heat stroke².  It also may increase （1）flooding and air pollution. 
A team of scientists from Johns Hopkins University in (2) Baltimore, Maryland examined connections between climate, weather conditions and human health risks. The (3) Global³ Change Research Program of the Environmental⁴ Protection⁵ Agency⁶ organized the research.  It is the first time that public health experts have examined the possible health effects of (4) worldwide climate change in the United States.
In recent years, the cities of Chicago, Illinois， Philadelphia, Pennsylvania and (5) Cincinnati, Ohio have had long periods of extreme⁷ heat.  Hundreds of people became sick and died.  Experts say many American cities are not prepared for severe⁸ heat. They say this problem will probably increase in the future.
Extreme weather events such as severe storms cause hundreds of deaths and injuries in the United States each year.  Researchers say climate change could increase these events.  They say rising temperatures will increase rainfall, cause sea levels to rise and increase floods and other severe weather events. 
Experts say water and food supplies could become unsafe by increases in rainfall and flooding. Weather influences the transport of （6）bacteria.
Hotter weather is also expected to increase air pollution. As air heats up, it mixes with sunlight⁹ to produce （7）ozone smog. This pollution slows the growth¹⁰ of plants and trees.  It can also damage human lungs. 
Scientists say Americans will also be at greater risk of diseases¹¹ such as （8）dengue, yellow fever and （9）malaria. These diseases are usually found in very warm climates. They are passed to humans by insects. They were once common in the United States.  Scientists say Americans could be at risk again if disease-carrying insects move to other warm and wet climates.  Scientists also say international travel can transport diseases to other countries.
The study calls for better efforts to protect the public health against the effects of air pollution, extreme heat, floods and other severe weather events.
