While I already mentioned some of the devastating dust storms of the past, I was surprised to see red dust storms happening here on Earth right now. The recent fires in Australia have created some massive dust storms off the coast of Western Australia that have to be seen to be believed. Below is an image of a "red wave" provided by The Newcastle Herald. The paper noted that "The Bureau of Meteorology said the incredible sight of a 'red wave' at sea was created as wind and rain caused the storm to dump the sand
and dust it had taken from the land."
You can find more images here, such as the two below.
