One of my favorite websites is Spaceweather.com, run by NASA. Spending some time on that site, especially when they are learning what really happens during a deep solar minimum or what may happen during a Coronal Mass Ejection, is an eye-opener to just how fragile this planet is.
It is a pure miracle we can converse today. And yes, we are most definitely “doomed”.
“how fragile this planet is.”
I just don’t believe it is fragile. It has been here billions of years and has uncounted events occur and yet, it is still here, unique to the universe.
