How does the war in Ukraine affect the global economy?

I finally started studying macroeconomics and I'm interested in knowing more about the global economy. With the war in Ukraine, I was curious to know: <br>- Do we have projections on what will happen if it continues/nations start war? <br>- Is there any potential war damage that hasn't been factored in? <br>- How much damage to infrastructure must happen to cause long term economic detriment?<br><br>Thank you for your help, it's not really in my wheelhouse.
