No, severe weather events have not become more frequent or more extreme.
From my latest at Town Hall:
Hard data, collected over decades, show no increase in the frequency or severity of hurricanes over the past century. Additionally, droughts are not more common, severe, or of greater length . . .
In recent decades, flooding has become more common in some places, while it has declined in other regions. Yet evidence indicates manmade land alterations, such as channelizing streams and rivers and filling areas with impervious surfaces (concrete, buildings, and parking lots) are mostly responsible for the flooding, not modestly warmer temperatures or increased rainfall.
Although severe weather events have not become more extreme, the mainstream media and environmental zealots have resorted to endless fearmongering campaigns to make the public believe this is happening because of climate change.
