Asked to slide into Dale Earnhardt's car days after his death, Harvick felt uneasy about replacing the Intimidator. Now, a decade after Earnhardt's fatal crash at Daytona, Harvick has embraced his role and was comfortable enough to deliver an emotional speech to his Richard Childress Racing team.

FILE - In this Oct. 12, 2000 file photo, an inspector wades through the checkout aisles of a supermarket in Uckfield, south of London, as the local river burst its bank and caused the town to flood, after several days of heavy rain and a night of severe storms. Two studies in the journal Nature link global warming to extreme rainstorms and snowfalls and find these weather events are getting substantially worse. One study found that the strongest precipitation events were 7 percent wetter in the 1990s than they were in the 1950s. The other looked at costly flooding in England and Wales in the fall of 2000 and found that global warming more than doubled the likelihood of that flood occurring. Both studies used computer modeling. (AP Photo/Alastair Grant, File)
