This is the worst podcast I've listened to in a long time, lots of out dated views straight out of the 80's. Very disapointing Dr Karl, I thought u would have followed the science instead of this rot.

For the first time ever in my 70 year life I now understand why there is also a high tide on the side away from the moon! I have been pondering this for at least 50 years! Now I can visualise it.
