Wilting heat, deadly storms, flash floods, coastal erosion, more days with unhealthy air &#151; those are just some of the effects of rising temperatures on the Northeast, a group of scientists reported Wednesday. They urged governments and citizens to take steps now to avoid the most devastating consequences of global warming.
