Floods have always threatened Americans.
I'm guessing you're not familiar with the 1889 Johnstown, Pennsylvania flood.
I'll bet you attribute that to global warming, too.

Record number compared to what, exactly?
Do you even understand how your world works?
How many tornadoes were there in the decade of the 1940s?
Don't even attempt to answer, because you can't, since no one knows.
Apparently, you're unable to discern the difference between tornadoes that are observed, and those that are not.
If a tornado touches down in a farmer's field in Kansas at 3:00 AM in 1946, who knows?
No one knows, because no one saw it.
The next day, or perhaps days later, the farmer trolling his fields might find evidence of tornado, but he tells no one, because it isn't important. There's no point in contacting the local TV or radio station or the National Weather Service.
That tornado is never recorded in the data.
You had hundreds of tornadoes just like that, that were never observed and so never reported and never recorded as data.
That changed in the 1950s. Major airports and many regional airports now have radars that can see 25 miles. They can detect an F4 or F5, and sometimes an F3, but not F0s, F1s or F2s.
Over the next several decades, radars became more powerful, 40 mile range in the 1960s, 160 miles in the 1970s and 220 miles in the 1980s.
Then, in the 1990s, you covered every inch of the US with Doppler Radar.
Now, you can see all tornadoes F0s through F5s, even in areas where there are no people and no one physically observes them.
For the not-too-intelligent, it gives the false impression that tornadoes are increasing, when in fact the real truth is only the number of tornadoes
detected has increased.
The actual number of tornadoes that occur decade to decade has remained unchanged for the last several thousand years.
However, you now have the ability to detect 90% of all tornadoes, even when no one observes them, but a lot of F0s and F1s still go undetected.
There was an F0 in Oxford, Ohio a few years ago that wasn't detected by radar, but it happened to lift off the roof of one home and damage a few others, and that's the only reason it was recorded.
