You hear the meteorologists talking about Hurricane Harvey, that it’s a five hundred year flood or even a thousand, a tool of scientific deception to enhance their global warming mantra, because the level of floods were not measured and recorded a thousand years ago, so all they’re saying is that flooding from Harvey was a one in a thousand chance of happening, which assumes that they know that there were not such floods a thousand years ago, or five hundred, or eight hundred, or three hundred.
