>Nuclear will also boil over Swiss rivers and shallow lakes.

What on earth are you talking about?

Slight hyperbole, but nuclear reactors in Switzerland and France shut down more and more often because the water needed to cool them down is already too hot:

It is far from boiling, but these limits are there to avoid killing all life in the rivers.

Note though that those limits exist just like the emission limits for WiFi: it was a sane number when it was decided. It's not clear at all that raising the temperature a little more will "kill all life in the rivers". It would probably deserve some research.

I think it would be more accurate to say "avoid killing the most vulnerable life" crossing the line would not be the end of the world.
