So confident am I that the number of deaths from violent storms will continue to decline that I challenge Mr. McKibben - or Al Gore, Paul Krugman, or any other climate-change doomsayer - to put his wealth where his words are. I'll bet $10,000 that the average annual number of Americans killed by tornadoes, floods and hurricanes will fall over the next 20 years. Specifically, I'll bet that the average annual number of Americans killed by these violent weather events from 2011 through 2030 will be lower than it was from 1991 through 2010.
