The Chase Center hasn’t opened for business yet, and already a climate change report is putting into question the arena’s long-term viability.

According to a Zillow analysis, Bay Area homes worth $50 billion will be in “grave risk” of rising sea levels in 2050. Barring a dramatic global initiative to combat climate change, much of San Francisco’s Mission Bay could be swamped, along with 80,000 other properties, by 2100.

Which would bring new meaning to Splash Brothers. Or Splash Hit, for that matter.

We interrupt this dire forecast for a reality check: This was a calculated and deliberate endeavor by Golden State Warriors, who are certain they did their homework. In an interview with KCBS’ Matt Bigler, Warriors president and COO Rick Welts said the team is in receipt of a study that “guarantees us for the next hundred years. At least (based on what) we know today, we should be in great shape. It’s a hundred-year project.”

By the way, the Warriors aren’t the only local sports franchise working to mitigate the effects of sea level change as they build their forever home.

Mitigating is good. But the bugaboo is that climate change is a slippery little devil. What “we know today” may not be the conventional wisdom in a decade or two. Thus there is no sure way to know how the next 50 years are going to play out, never mind the next 80.

This much is certain. You can find voices on both sides of the complex issue — those who believe Mission Bay will be half full by the turn of the next century, and those who believe it will be half empty.

“This is going to be a tough truth,” he said, “but we are too late. We are 10 years too late. We need to do everything we can to start moving the climate in the right direction, but we also need to start moving out people to higher ground.”
