Been catching up on things.... this sounds devastating. I hope for the best for you and your family and friends. Glad to hear that you are safe.
I'm afraid that severe flooding is becoming more common due to the global climate crisis. As the polar ice caps melt away, sea levels and water tables rise. Places that were once safe from floods are now at risk. Countries like the U.S. and China, who are huge polluters, are most at fault due to the inaction of those governments. It's sad; even though many individuals take great care to reduce waste and fuel consumption in their daily lives, the problem continues to grow because our government refuses to enact limits and penalties on industrial polluters.
