One of the things we’re repeatedly told is that there will be some 200 million climate migrants by 2050 or so. Sounds like quite a flood really.
But do note, that’s the cumulative figure to 2050, not 200 million all trying to move in one year. Also:
More people than ever living outside their home country: Number of migrants worldwide hits 232 million
It’s less than the number of international migrants that we have at present.
And as we know, because we are continually told it, the current migration numbers are not a problem.
