I recommend that climate change activists take a look at this video. According to 24/7 News Source, “images of what's being called an ‘Ice Tsunami’ are taking social media by storm. It shows ice being blown from the Niagara River over a retaining wall in Ontario, Canada just across from Buffalo, New York.” Giant pieces of ice were sent spilling over the retaining wall, creating an icy barrier.
Here is a link to one of the videos: (caution there is some mild swearing on the video) https://www.youtube.com/watch?v=kzSudWe1QuE.
It shows the ice flowing over a retaining wall. Things were even more dramatic to the south in Hamburg, where ice mounds up to 30 feet tall also came ashore, piling up on a handful of lakefront properties. Winter is still in full force.
