The author hypothesizes that the increased reports of tornadoes since the 1950s is probably explained by our finding a higher percentage of tornadoes that occur rather than an increase in the actual number of tornadoes. This is based on the fact that our ability to find tornadoes has improved since the 1950s.

The author assumes that our ability to find tornadoes has increased enough to account entirely for the increased reports of tornadoes since 1950.

The argument concerns whether the number of tornadoes has increased. The damage produced by an average tornado does not reveal anything about the overall number of tornadoes.

If anything, this might undermine the argument by suggesting that there has been an increase in the number of tornadoes.

This suggests there hasn’t been an overall increase in actual tornadoes, because we’d expect all kinds of tornadoes to increase, not just the small ones. Instead, the explanation for the increased reports of small tornadoes might simply be easier identification of them.

If anything, this might undermine the argument by suggesting that there might be more tornadoes (which would account for the increased deaths due to tornadoes).

This tells us that the range in which tornadoes are most common has been about the same. But the range staying the same doesn’t tell us anything about the overall frequency of tornadoes within that range.
