Jason, that's bullshit.
Our planet doesn't have to rotate at any particular pace to stay in this orbit.
Obviously though, if it rotated 20x slower, the days would be 20x longer and the nights would be 20x longer as well. This would mean that part of the Earth would heat up much more while the other side cooled much more. As long as we still had an atmosphere like the one we have now, this would probably cause a lot of storms and wind also due to the extreme tempurature differences.

Well. If we lose the rotation speed, we lose our magnetic field. With that gone, all plant life is going to die very quickly at the hands of solar radiation. We'll be next.
Life plays a very critical role in keeping surface temperatures balanced. Plants convert carbon dioxide, a greenhouse gas, into oxygen- and with that done away you have only to look at our sister planet, Venus, to learn how things would be over here.
Venus is an oven with a steady 400 degree surface temperature. Atmospheric pressure is the same as being a mile underwater.
It is said that life could have existed on Venus long ago in the high elevations. An asteroid was thought to have hit the planet, slowing down its rotation.

The temperature would increase very much. The situation would be pretty much like Venus.

Imi: ok!
Ellis: sorry: It is not our rotation speed that makes our magnetic field and shield: it is the DIFFERENCE between surface and the core...

Pretty drastically, because we'd hurtle into the sun and be vaporized. The Earth needs to spin at this speed to stay in its orbit.
