Those who believe global warming is reality rather than science fiction have a new report to support their claims.
The National Wildlife Federation and the Asthma and Allergy Foundation of America says the heat that has gripped much of the country this summer could be worse and even standard fare by the year 2050.
Future heatwaves are predicted to be especially dangerous for asthma sufferers because of ever-increasing ozone levels. States from Florida to Maine have endured record or near-record temperatures this summer. Two states, Rhode Island and Delaware, saw their hottest July ever.
