According to various sources, Nostradamus predicted several events for 2023, but it is important to note that his predictions are often vague and open to interpretation. Here are some of the predictions that have been attributed to Nostradamus for 2023:

• Great War: Nostradamus predicted "a great war" that would result in many deaths due to evil-doing. Some followers speculate that this could entail a severe escalation of the conflict between the United States and Russia, perhaps due to the Russian invasion of Ukraine in 2022.

• Rising temperatures and sea levels: Nostradamus predicted that temperatures would rise further and sea levels would rise to unexpected levels. He wrote, "Like the sun, the head shall sear the shining sea: The Black Sea’s living fish shall all but boil."

• New Pope and Celestial fire: Nostradamus predicted the arrival of a new Pope, and that the next Pope would cause a debacle. He also foresaw "Celestial fire on the Royal edifice." This is thought to imply that a new world order will rise from the ashes of civilization.

• Failed economy and cannibalism: Nostradamus predicted that humanity may face the threat of cannibalism due to a failing economy, writing: "There are no abbots, monks, no novices to teach. Honey will cost much more than candle wax, the price of wheat will be high. Man will be agitated and eat his friend in despair".

• Climate disaster: Nostradamus predicted that the dry land will dry up even more and there will be great floods when you see the rainbow. As climate change continues to worsen, this forecast doesnt seem far-fetched for the coming year.

It is important to note that Nostradamus predictions are often open to interpretation and are not always accurate. While some of his predictions have come true in the past, many others have not.
