Global Warming: Causes and Effects>The United States was responsible for 20% of the global greenhouse gases emitted in 1997.(Greenhouse gases are emissions that rise into the atmosphere and trap the sun's energy keeping heat from escaping.) >Most of the world's emissions are attributed to the United States' large-scale use of fuels in vehicles and factories.>Damaging storms, droughts and related weather phenomena cause an increase in economic and health problems. Warmer weather provides breeding grounds for insects such as malaria-carrying mosquitoes. >Earths temperature has risen 1 degree Fahrenheit in the last century. The past 50 years of warming has been attributed to human activity.
