Yes, they are.
But we know this is happening. So we can deal with it in two ways:
1. Reduce output of pollution/heat to reduce greenhouse effect & rising seas
2. Start to move stuff away from the ocean. The rise is happening slowly, so require new infrastructure to be 20 feet, or whatever, above sea levels.
Or I guess we could just keep hoping it goes away, or the idiots on the House Science committee pray it away...
