I best reply to myself as otherwise I'd be covering points made by several others.

Firstly, the initial question was abut what to do about the migrant situation and very few have offered meaningful suggestions about what to do about the situation as it exists now.

The thread has been off-topic all over the place and somehow climate change has been one of the points raised. What climate change has got to do with the migrant situation I don't know but the resident sesquipedalian doesn't seem to think that the Sun is the driving force behind life on this Planet but it just happens to be so. The Planet itself also enters the fray and affects life here and also affects the climate. Rock, ice and mud (sediment) samples clearly show how the climate changed over millions of years swapping back and to between extremes of heat and cold long, long before Man appeared on the Planet.

The Japanese earthquake of 2011 shifted the Earth's axis by over 6 inches and while that's not a lot, had Man had anything to do with it there would be good reason to point the finger at him.

So, if Man is now affecting climate change so drastically, how come similar changes in climate happened millions of years before he appeared? That said, if you want to continue with climate change, please start a new thread.

These migrants are heading for the UK because it seems likely that they've been told (by using the benefits of modern communications) that the UK is the land of Milk and Honey where the fools give you money and houses for nothing. If they were merely escaping some form of persecution, wouldn't you think that the first place of refuge that they got to would have been their safe haven? Why trek thousands of miles more if there wasn't another reason?

What to do with them? Send them back.
